Abstract
The Asian longhorned tick, Haemaphysalis longicornis, is an invasive species, originally from eastern Asia, and was first reported in the USA in New Jersey. It is now reported in several eastern states. In 2018, researchers reported H. longicornis in northwest Arkansas (Benton County). This tick species is a proven vector of livestock and human diseases, which prompted the current survey of ticks in southwest Missouri. A tick drag in Greene County, Missouri, produced 2 H. longicornis nymphs on June 9, 2021. This is the first report of this species for both the state and county.

Abstract
A survey of adult and immature mosquitoes in southern and western Missouri conducted from June 14 to September 23, 2016, yielded 32 species and 7 genera. The invasive species Aedes albopictus and Ae. japonicus were dispersed widely in the state, but the survey failed to collect any Ae. aegypti. This note discusses the impact of changes in the Missouri mosquito fauna on the risk of human disease transmission.

Abstract
During its deployment to Kuwait from 2011-2012, the 983rd Medical Detachment (Preventive Medicine) was augmented with a 4-person laboratory section which provided polymerase chain reaction capabilities not normally associated with an Army Level III preventive medicine detachment. Although common in many civilian laboratories, this was the first time this equipment was used by a deployed Level III Army preventive medicine detachment to identify an outbreak in this theater. It allowed rapid identification and description of a gastrointestinal disease outbreak caused by norovirus in Kuwait. The technology contributed to a decreased time required to identification of the causative agent (hours vs days) and thus the implementation of appropriate preventive measures. Based on this event, the authors suggest the addition of a modified laboratory section to the modified table of organization equipment for deployable preventive medicine detachments.

Abstract
An inexpensive and rapid bioassay using adult red flour beetles was developed for use in assessing the decontamination of environments containing organophosphates and related chemicals. A decontamination protocol was developed which demonstrated that 2 to 3 applications of 5% bleach solution were required to obtain nearly complete decontamination of malathion. The bioassay was also used to screen common household cleaners as potential decontaminating agents, but only 5% bleach was effective at improving survival of insects on steel plates treated with 25% malathion. A toxic degradation product (malaoxon) was detected using gas chromatography/mass spectrophotometry; this toxin affected the decontamination efficacy and resulted in continued toxicity to the beetles until subsequent decontaminations. The bioassay provides evidence to support the use of red flour beetles as a sensitive, less expensive method for determining safety levels of environments contaminated with malathion and other toxins, and may have application in the study of chemical warfare agents.

Abstract
Vector control remains a key component of many anti-leishmaniasis programs and probably will remain so until an effective vaccine becomes available. Technologies similar to those used for control of adult mosquitoes, specifically interior residual sprays and insecticide-treated nets, are currently at the forefront as disease control measures. This article provides a review of literature on the biology and control of sand fly vectors of leishmaniasis in the context of changing disease risks and the realities of modern vector control. The Literature Retrieval System of the Armed Forces Pest Management Board, Washington, DC, was the primary search engine used to review the literature.

Abstract
OBJECTIVE To monitor adult mosquito abundance in northern Belize before/after the first tropical storm of the wet season to estimate the time required for development/recovery of potential vector populations; determine which species predominate post-storm; and compare the effectiveness of two types of mosquito traps-octenol-baited Mosquito Magnets® and U.S. Centers for Disease Control and Prevention (CDC) light traps (with/without octenol). METHODS Field experiments were conducted in Orange Walk Town, Belize, 21 May to 3 June 2008. Incidence rate ratios and exact binomial 95% confidence intervals were reported and trap-nights calculated to compare species abundance pre- and post-storm as well as trap-type effectiveness. RESULTS Twice as many species and three times more Anopheles spp. were trapped pre-storm versus post-storm. However, greater numbers of Aedes taeniorhynchus and Culex (Culex) spp. were trapped post-storm. Mosquito Magnets® were consistently more effective than the CDC traps, obtaining twice as many Anopheles spp. and four times as many culicine species as the octenol-baited version (which collected 14 times more mosquitoes overall and 3.5 times more culicine species than the unbaited version). The unbaited CDC trap did not trap any Anopheles spp. during the study period. CONCLUSIONS Results indicated octenol is an effective attractant for An. crucians in northern Belize; malaria risk in Belize declines immediately post-storm (i.e., mosquito abundance drops); and arboviral risk associated with the rapid increase in culicine mosquitoes post-storm may represent a greater public health threat than malaria (although further research and active disease surveillance is necessary to validate this hypothesis).

Abstract
Most studies on interior (or indoor) residual spraying (IRS) have been targeted on permanent/semipermanent structures. We measured the utility of a portable field bioassay, which can be set up quickly to determine the best chemical repellent or irritant for use as an IRS during an emergency or military situation when displaced persons are temporarily housed in tents. If the bioassay were used over an extended period of time, it would also offer a unique way to monitor vector susceptibility and would be able to determine which chemical is most efficient in individual populations. In total, 2193 mosquitoes belonging to seven species in five genera were collected over the study period. No statistical differences were found between any of the treatments, control, and standard tents utilizing the 4 x 4 Latin square design. Therefore, we conclude that IRS with these tested chemicals in military-issued two-person tents are not effective or significant at stopping mosquito entrance. Further studies on implementation of a portable, field bioassay should include utilizing different mosquito traps in the bioassay and looking at the difference between contact irritants and spatial repellents in different-sized tents, as spatial repellency may be more important in smaller-sized tents.

Abstract
Over 35,000 cases of Japanese encephalitis (JE) are reported worldwide each year. Culex tritaeniorhynchus is the primary vector of the JE virus, while wading birds are natural reservoirs and swine amplifying hosts. As part of a JE risk analysis, the ecological niche modeling programme, Maxent, was used to develop a predictive model for the distribution of Cx. tritaeniorhynchus in the Republic of Korea, using mosquito collection data, temperature, precipitation, elevation, land cover and the normalized difference vegetation index (NDVI). The resulting probability maps from the model were consistent with the known environmental limitations of the mosquito with low probabilities predicted for forest covered mountains. July minimum temperature and land cover were the most important variables in the model. Elevation, summer NDVI (July-September), precipitation in July, summer minimum temperature (May-August) and maximum temperature for fall and winter months also contributed to the model. Comparison of the Cx. tritaeniorhynchus model to the distribution of JE cases in the Republic of Korea from 2001 to 2009 showed that cases among a highly vaccinated Korean population were located in high-probability areas for Cx. tritaeniorhynchus. No recent JE cases were reported from the eastern coastline, where higher probabilities of mosquitoes were predicted, but where only small numbers of pigs are raised. The geographical distribution of reported JE cases corresponded closely with the predicted high-probability areas for Cx. tritaeniorhynchus, making the map a useful tool for health risk analysis that could be used for planning preventive public health measures.

Abstract
Funnel traps are often used to sample for the presence of Aedes aegypti (L.) (Diptera: Culicidae) larvae in subterranean aquatic habitats. These traps are generally > or = 15 cm in diameter, making them impractical for use in subterranean sites that have narrow (10-cm) access ports, such as those in standard-sized septic tanks. Recent research indicates septic tanks may be important habitats for Ae. aegypti in Puerto Rico and the Caribbean. To sample mosquito larval populations in these sites, a miniaturized funnel trap was necessary. This project describes the use of a smaller funnel trap for sampling larval populations. The effects of larval instar (third and fourth) and population density on trap efficacy also are examined. The trap detected larval presence 83% of the time at a larval density of 0.011 larvae per cm(2) and 100% of the time at densities > or = 0.022 larvae per cm(2). There was a significant trend of increasing percentage of recaptured larvae with higher larval population densities. Although the miniaturized funnel trap is less sensitive at detecting larval presence in low population densities, it may be useful for sampling aquatic environments with restricted access or shallow water, particularly in domestic septic tanks.

Abstract
Leishmania infections in American veterans of Iraq and Afghanistan have raised concern that veterans could serve as reservoirs of Old World parasites for domestic vector populations. A survey of sand flies on three U.S. Army facilities in the southern United States was conducted to identify potential vectors. Five species, including two new state records, are reported for Fort Hood, TX. Very few flies were detected in Fort Bragg, NC. Large numbers of a man-biting species, Lutzomyia shannoni, were trapped on Fort Campbell, KY. Weekly activity patterns for dominant species are presented. In addition, an infection experiment was conducted to determine if a domestic sand fly is susceptible to infection with Old World Leishmania major. Lu. shannoni became infected and supported Le. major up to 6 days postprandial. Metacyclogenesis and actual transmission of Le. major to an uninfected mouse did not occur because infected flies did not take subsequent blood meals.

Abstract
Sand fly fever has severely impacted military missions in southern Europe and the Middle East for hundreds of years. After a brief respite following the malaria eradication programs of World War II, it has returned as a significant disease among residents in and travelers to the Mediterranean rim. It is a more severe disease now, with potential vectors in the United States. Sand fly fever is discussed in terms of its viruses, vectors, disease, control, and potential domestic impact.

Abstract
Two species of phlebotomine sand flies, Lutzomyia shannoni (Dyar) and Lutzomyia vexator (Coquillett), are reported for the first time from Kentucky and Ohio. L. vexator also is reported for the first time from Tennessee. These insects were found in a northeasterly band extending from southwestern Kentucky to southwestern Ohio. Both species were consistently captured from mid-July through September in 2006 and 2007 by using CO2-baited Center for Disease Control light traps. Weekly sampling revealed that these flies are more abundant in the southern part of this band than in the northern part, but increasing densities throughout this new range indicate that the flies are currently expanding their range. Although both species have been reported further north along the Atlantic coast, and L. vexator along the Pacific coast, neither of them had been reported this far north along the Mississippi Valley. Previous reports established L. shannoni as far north as west central Tennessee and L. vexator in a similar spatial pattern in the eastern part of its range, extending as far north as northern Alabama. Whether the new records reported herein represent a northerly expansion of the geographic range of these species or are reflective of sampling changes is inconclusive. However, the former scenario could presage an increased prevalence of the diseases associated with this group of insects.

Abstract
Surveillance and control procedures for the mosquito vectors of West Nile virus (WNV) and other arboviruses are described in response plans that vary among states. To ensure that naval installations in the eastern United States follow WNV response plan criteria similar to those of their host states, we conducted a telephone survey of 25 personnel who directed surveillance and control procedures in areas near these installations. For adult mosquito surveillance, 76% of respondents used Centers for Disease Control and Prevention miniature light traps baited with dry ice; 68% of respondents used these and baited Centers for Disease Control and Prevention gravid traps. We report a summary of the mosquito species that were most problematic among states. In the eastern United States, these species have tested positive for WNV and some have been reported as potential vectors of WNV and other arboviruses. Among respondents, numerical thresholds or the presence of WNV-positive mosquito pools facilitated decision-making (i.e., whether to increase surveillance or to initiate control procedures). The presence of mosquito larvae, abiotic variables, and historical databases were also important. Reports of dead birds and human serology data were used by 92% and 64% of respondents, respectively. Adult control was accomplished with synthetic pyrethroids; larvae were controlled with microbial insecticides and growth regulators. Geographic information systems and public awareness/education were used by 60% and 88% of respondents, respectively. We discuss our results in light of response plan variability and implications for the future.

Abstract
There are several natural and artificial factors that mimic the effects of chemical warfare agents, thereby causing unwarranted alarm and confusion on the battlefield. Symptoms associated with chemical warfare include paralysis, muscle tremors, heavy salivation, severe burns, blistering, and corrosive skin injuries among others. Similar symptoms can be produced from a variety of environmental sources, artificial and natural. This article reviews several published and unpublished examples of environmental factors that produce syndromes similar to those caused by these agents. Examples of such mimics include pesticides, blistering exudates from insects and plants, various types of bites, and naturally occurring diseases. The potential for confusion caused by these factors is discussed and means of discriminating between warfare agents and naturally occurring events are identified. Recommendations for the use of this information and for needed research are also discussed.

Abstract
The larval habitats of malaria vectors near the Demilitarized Zone of the Republic of Korea (ROK) were sampled from June through September 2000 to determine larval abundance and to identify environmental factors associated with high larval density. Six primary habitats were identified: rice fields, irrigation ditches, drainage ditches, stream pools, irrigation pools, and marshes. Most habitats harbored similar densities of larvae until August and September, when population densities in rice fields declined and those in irrigation pools increased. The primary vector in the ROK, Anopheles sinensis, occurred in water with a wide range of values for environmental factors, including pH, total dissolved solids, percent of surface covered with floating vegetation, and nitrate and phosphate concentrations. No environmental factor or combination of factors were found that were predictive of high larval densities. This study suggests that larval Anopheles are capable of developing in a wide range of stagnant, freshwater habitats in northern Kyunggi Province, ROK.

Abstract
A cost-comparison of two methods for the control of malaria in the Republic of Korea was performed. The cost of larviciding with methoprene granules was estimated at $93.48/hectare. The annual cost of providing chemoprophylaxis was estimated at $37.53/person. Remote sensing and geographic information systems were used to obtain estimates of the size of vector larval habitats around two U.S. Army camps, allowing an estimate of the cost of larviciding around each of the camps. This estimate was compared to the cost of providing chloroquine and primaquine chemoprophylaxis for the camp populations. Costs on each of the camps differed by the size of the larval habitats and the size of the at-risk population. These tools allow extrapolation of larval surveillance data to a regional scale while simultaneously providing site-specific cost analysis, thus reducing the cost and labor associated with vector surveillance over large areas.

Abstract
Field trials evaluating selected commercially available mosquito traps variously baited with light, carbon dioxide, and/or octenol were conducted from 18-27 September 2000 in a malarious area near Paekyeon-ri (Tongil-Chon) and Camp Greaves in Paju County, Kyonggi Province, Republic of Korea. The host-seeking activity for common mosquito species, including the primary vector of Japanese encephalitis, Culex tritaeniorhynchus Giles, was determined using hourly aspirator collections from a human and propane lantern-baited Shannon trap during hours when temperatures exceeded 15 degrees C. The total number of mosquitoes and number of each species captured during the test was compared using a block design. Significant differences were observed for the total number of mosquitoes collected, such that, the Mosquito MagnetTM with octenol > Shannon trap > ABC light trap with light and dry ice > Miniature Black Light trap (manufactured by John W. Hock) > or = New Jersey Trap > ABC light trap with light only. Significant differences in numbers collected among traps were noted for several species including: Aedes vexans (Meigen), Anopheles lesteri Baisas and Hu. An. sinensis Weidemann. An. sineroides Yamada, An. yatsushiroensis Miyazaki, Culex pipiens pallens Coquillett L., Cx. orientalis Edwards and Cx. tritaeniorhynchus. Host-seeking activity for most common species showed a similar bimodal pattern. Results from these field trap evaluations can significantly enhance current vector and disease surveillance efforts especially for the primary vector of Japanese encephalitis, Cx. tritaeniorhynchus.

A concurrent 5 x 5 test found significant differences in trap catch, where Mosquito Magnet with octenol > New Jersey light trap > or = EPAR Mosquito Killer with CO2 > or = ABC light trap with light and dry ice > Centers for Disease Control (CDC) light trap (manufactured by John W. Hock) with light and octenol. Significant differences in trap catch were noted for several species including: Aedes vexans, Anopheles sinensis, An. yatsushiroensis, An. lesteri, Culex pipiens, and Cx. orientalis. Traps baited with octenol captured significantly fewer Cx. pipiens than those not baited with octenol. Likewise, no Cx. orientalis were captured in octenol-baited traps. Host-seeking activity showed a similar bimodal pattern for all species captured. Results from these field trap evaluations can significantly enhance surveillance efforts. Significantly greater numbers of mosquitoes were captured with mosquito traps using counterflow technology (e.g., Mosquito Magnet and CFG traps) when compared to standard light and carbon dioxide-baited traps. Additionally, field evaluations demonstrate that various traps can be utilized for isolation and detection of arboviruses and other pathogens.

Abstract
An outbreak of a blistering disease was reported in a military unit training in the Arizona desert during heavy rain and flooding. In a unit of 249 personnel, 33 presented with dermatologic complaints, and 4 met stringent diagnostic criteria for dermatitis linearis. A fifth patient presented with symptoms and signs of "Nairobi eye." Staphylinid (rove) beetles related to the paederids, which have been responsible for vesicular dermatitis outbreaks in other parts of the world but not previously in the United States, were collected at the site. Reports in the antique scientific literature document paederids in the area after periodic floods. These findings suggest that rove beetle dermatitis should be added to the differential diagnosis of vesicular dermatitis in western North America.
