Abstract
We have developed an online database describing the known cell lines from Coleoptera, Diptera, Hemiptera, Hymenoptera, and Lepidoptera that were developed from agricultural pests. Cell line information has been primarily obtained from previous compilations of insect cell lines. We conducted in-depth Internet literature searches and drew on Internet sources such as the Cellosaurus database (https://web.expasy.org/cellosaurus/), and inventories from cell line depositories. Here, we report on a new database of insect cell lines, which covers 719 cell lines from 86 species. We have not included cell lines developed from Drosophila because they are already known from published databases, such as https://dgrc.bio.indiana.edu/cells/Catalog. We provide the designation, tissue and species of origin, cell line developer, unique characteristics, its use in various applications, publications, and patents, and, when known, insect virus susceptibility. This information has been assembled and organized into a searchable database available at the link https://entomology.ca.uky.edu/aginsectcellsdatabase which will be updated on an ongoing basis.

Abstract
The origin of the order Hemiptera can be traced to the late Permian Period more than 230 MYA, well before the origin of flowering plants 100 MY later in during the Cretaceous period. Hemipteran species consume their liquid diets using a sucking proboscis; for phytophagous hemipterans their mouthparts (stylets) are elegant structures that enable voracious feeding from plant xylem or phloem. This adaptation has resulted in some hemipteran species becoming globally significant pests of agriculture resulting in significant annual crop losses. Due to the reliance on chemical insecticides for the control of insect pests in agricultural settings, many hemipteran pests have evolved resistance to insecticides resulting in an urgent need to develop new, species-specific and environmentally friendly methods of pest control. The rapid advances in CRISPR/Cas9 technologies in model insects such as Drosophila melanogaster, Tribolium castaneum, Bombyx mori, and Aedes aegypti has spurred a new round of innovative genetic control strategies in the Diptera and Lepidoptera and an increased interest in assessing genetic control technologies for the Hemiptera. Genetic control approaches in the Hemiptera have, to date, been largely overlooked due to the problems of introducing genetic material into the germline of these insects. The high frequency of CRISPR-mediated mutagenesis in model insect species suggest that, if the delivery problem for Hemiptera could be solved, then gene editing in the Hemiptera might be quickly achieved. Significant advances in CRISPR/Cas9 editing have been realized in nine species of Hemiptera over the past 4 years. Here we review progress in the Hemiptera and discuss the challenges and opportunities for extending contemporary genetic control strategies into species in this agriculturally important insect orderr.

Abstract
Aphids are common agricultural pests with a wide range of hosts from agriculture to forestry plants. As known, aphids also serve as the major vectors to transmit plant viruses. Although numerous studies have focused on interactions between aphids and plant viruses, little is known about the aphid viruses, i.e., the insect viruses that are infectious to aphids. In the past four decades, several aphid viruses have been identified in diverse aphid species. In this review, we present a brief view of the aphid pathogenic viruses from several aspects, including classification of aphid viruses and characters of the viral genome, integration of viral sequences in host genomes, infection symptoms and influence on aphids, as well as host range and transmission modes. Taken together, these studies have increased our understanding of the rarely known aphid viruses, and will potentially contribute to the development of new strategies for controlling aphid populations.

Abstract
The use of viruses for biological control is a new option to be considered. The family Dicistroviridae, which affects only invertebrates, is one of the families that have been proposed for this purpose. The Triatoma virus (TrV), a member of this family, affects triatomine transmitters of Chagas disease, which is endemic in Latin America but also expanding its worldwide distribution. To this end, we attempted virus replication in Diptera, Aedes albopictus (clone C6/36) and Lepidoptera Spodoptera frugiperda (SF9, SF21) and High Five (H5) cell lines. The methodologies used were transfection process, direct inoculation (purified virus), and inoculation of purified virus with trypsin. Results were confirmed by SDS-PAGE, Western blotting, RT-PCR, electron microscopy, and immunofluorescence. According to the results obtained, further analysis of susceptibility/infection of H5 cells to TrV required to be studied.

Abstract
The rice brown planthopper (BPH), Nilaparvata lugens (Stål), is one of the most destructive insect pests of rice in Asia. Although resistant rice varieties can be effective in managing planthopper populations, BPH has repeatedly been able to overcome resistant rice varieties. It is possible that BPH adaptation to resistant rice varieties may be related to its endosymbionts. We investigated methods for culturing BPH cells in order to study in-depth interactions between rice, BPH, and its endosymbionts. In this study, we tested EX-CELL™ 405, EX-CELL™ 420, Mitsuhashi and Maramorosch's medium, and Kimura's medium, for in vitro culture of BPH cells. Only Kimura's medium was found to be suitable for BPH cell culture, and BPH embryos around blastokinetic stage were the best source for BPH cell culture. Cells from BPH embryonic tissues adhered to the plate substrate, and the migration of cells was observed within 24 h in primary culture. After 3 mo of subculture, various types of BPH cells were successfully maintained in the Kimura's medium.

Abstract
The first continuous cell line from the embryo of Gampsocleis gratiosa (Orthoptera: Tettigoniidae), designated as RIRI-GG1, was established. This cell line was serially subcultured in modified Grace medium. The cells were grown adherent to a culture flask and had spindle-like and polygonal shapes. The chromosome number ranged from 26 to 79 at the 50th passage, and 68% of cells had a diploid chromosome number. The growth rate was determined at the 53rd passage, and the population doubling time was calculated to be 122.1 h. The rDNA internal transcribed spacer and the mitochondrial cytochrome c oxidase subunit I gene sequence analysis indicated that the RIRI-GG1 cell line was derived from G. gratiosa. This cell line had no apparent susceptibility to Autographa californica nucleopolyhedrovirus and Bombyx mori nucleopolyhedrovirus.

RNA viruses in hymenopteran pollinators: evidence of inter-Taxa virus transmission via pollen and potential impact on non-Apis hymenopteran species. PLoS One 2010; 5:e14357.

Abstract
Although overall pollinator populations have declined over the last couple of decades, the honey bee (Apis mellifera) malady, colony collapse disorder (CCD), has caused major concern in the agricultural community. Among honey bee pathogens, RNA viruses are emerging as a serious threat and are suspected as major contributors to CCD. Recent detection of these viral species in bumble bees suggests a possible wider environmental spread of these viruses with potential broader impact. It is therefore vital to study the ecology and epidemiology of these viruses in the hymenopteran pollinator community as a whole. We studied the viral distribution in honey bees, in their pollen loads, and in other non-Apis hymenopteran pollinators collected from flowering plants in Pennsylvania, New York, and Illinois in the United States. Viruses in the samples were detected using reverse transcriptase-PCR and confirmed by sequencing. For the first time, we report the molecular detection of picorna-like RNA viruses (deformed wing virus, sacbrood virus and black queen cell virus) in pollen pellets collected directly from forager bees. Pollen pellets from several uninfected forager bees were detected with virus, indicating that pollen itself may harbor viruses. The viruses in the pollen and honey stored in the hive were demonstrated to be infective, with the queen becoming infected and laying infected eggs after these virus-contaminated foods were given to virus-free colonies. These viruses were detected in eleven other non-Apis hymenopteran species, ranging from many solitary bees to bumble bees and wasps. This finding further expands the viral host range and implies a possible deeper impact on the health of our ecosystem. Phylogenetic analyses support that these viruses are disseminating freely among the pollinators via the flower pollen itself. Notably, in cases where honey bee apiaries affected by CCD harbored honey bees with Israeli Acute Paralysis virus (IAPV), nearby non-Apis hymenopteran pollinators also had IAPV, while those near apiaries without IAPV did not. In containment greenhouse experiments, IAPV moved from infected honey bees to bumble bees and from infected bumble bees to honey bees within a week, demonstrating that the viruses could be transmitted from one species to another. This study adds to our present understanding of virus epidemiology and may help explain bee disease patterns and pollinator population decline in general.

Abstract
Dicistroviruses are members of a recently defined and rapidly growing family of picornavirus-like RNA viruses called the Dicistroviridae. Dicistroviruses are pathogenic to beneficial arthropods such as honey bees and shrimp and to insect pests of medical and agricultural importance. Our understanding of these viruses is uneven. We present highly advanced studies of the virus particle structure, remarkable mechanisms of internal ribosome entry in translation of viral RNA, and the use of dicistroviruses to study the insect immune system. However, little is known about dicistrovirus RNA replication mechanisms or gene function, except by comparison with picornaviruses. The recent construction of infectious clones of dicistrovirus genomes may fill these gaps in knowledge. We discuss economically important diseases caused by dicistroviruses. Future research may lead to protection of beneficial arthropods from dicistroviruses and to application of dicistroviruses as biopesticides targeting pestiferous insects.

Abstract
Pea enation mosaic virus (PEMV: family Luteoviridae) is transmitted in a persistent, circulative manner by aphids. We inserted cDNAs encoding the structural proteins of PEMV, the coat protein (CP) and coat protein-read through domain (CPRT) into the genome of the baculovirus Autographa californica multiple nucleopolyhedrovirus with and without a histidine tag or an upstream Kozak consensus sequence. The Sf21 cell line provided the highest level of CP expression of the cell lines tested and resulted in production of virus-like particles (VLPs). The CPRT was not detected in recombinant baculovirus-infected cells by Western blot. Addition of a Kozak sequence increased the yield of baculovirus produced VLPs. Baculovirus-expressed VLPs purified on a nickel NTA column were of variable size (13-30 nm) and contained CP mRNA. The purified VLPs were also shown by RT-PCR to contain 70% of 154 baculovirus mRNAs, indicative of non-specific RNA encapsidation in the absence of viral RNA replication. When fed to the pea aphid, Acyrthosiphon pisum (Harris), the VLPs entered the aphid hemocoel, demonstrating that CPRT is not required for uptake of PEMV from the aphid gut. Baculovirus expression of PEMV VLPs provides a useful tool for future analysis of RNA encapsidation requirements and molecular aphid-virus interactions.

Abstract
Availability of a cloned genome from which infectious RNA can be transcribed is essential for investigating RNA virus molecular mechanisms. To date, no such clones have been reported for the Dicistroviridae, an emerging family of invertebrate viruses. Previously we demonstrated baculovirus-driven expression of a cloned Rhopalosiphum padi virus (RhPV; Dicistroviridae) genome that was infectious to aphids, and we identified a cell line (GWSS-Z10) from the glassy-winged sharpshooter, that supports RhPV replication. Here we report that RNA transcribed from a full-length cDNA clone is infectious. Transfection of GWSS-Z10 cells with the RhPV transcript resulted in cytopathic effects, ultrastructural changes, and accumulation of progeny virions, consistent with virus infection. Virions from transcript-infected cells were infectious in aphids. This infectious transcript of a cloned RhPV genome provides a valuable tool, and a more tractable system without interference from baculovirus infection, for investigating replication and pathogenesis of dicistroviruses.

Abstract
Detailed investigation of virus replication is facilitated by the construction of a full-length infectious clone of the viral genome. To date, this has not been achieved for members of the family Dicistroviridae. Here we demonstrate the construction of a baculovirus that expresses a dicistrovirus that is infectious in its natural host. We inserted a full-length cDNA clone of the genomic RNA of the dicistrovirus Rhopalosiphum padi virus (RhPV) into a baculovirus expression vector. Virus particles containing RhPV RNA accumulated in the nuclei of baculovirus-infected Sf21 cells expressing the recombinant RhPV clone. These virus particles were infectious in R. padi, a ubiquitous aphid vector of major cereal viruses. The recombinant virus was transmitted efficiently between aphids, despite the presence of 119 and 210 vector-derived bases that were stably maintained at the 5' and 3' ends, respectively, of the RhPV genome. The maintenance of such a nonviral sequence was surprising considering that most RNA viruses tolerate few nonviral bases beyond their natural termini. The use of a baculovirus to express a small RNA virus opens avenues for investigating replication of dicistroviruses and may allow large-scale production of these viruses for use as biopesticides.
