Abstract
Cassava is an essential tuber crop used to produce food, feed, and beverages. Whitefly pests, including Aleurothrixus aepim (Goeldi, 1886) (Hemiptera: Aleyrodidae), significantly affect cassava-based agroecosystems. Plant odours have been described as potential pest management tools, and the cassava clone M Ecuador 72 has been used by breeders as an essential source of resistance. In this study, we analysed and compared the volatile compounds released by this resistant clone and a susceptible genotype, BRS Jari. Constitutive odours were collected from young plants and analysed using gas chromatography-mass spectrometry combined with chemometric tools. The resistant genotype released numerous compounds with previously described biological activity and substantial amounts of the monoterpene (E)-β-ocimene. Whiteflies showed non-preferential behaviour when exposed to volatiles from the resistant genotype but not the susceptible genotype. Furthermore, pure ocimene caused non-preferential behaviour in whiteflies, indicating a role for this compound in repellence. This report provides an example of the intraspecific variation in odour emissions from cassava plants alongside information on odorants that repel whiteflies; these data can be used to devise whitefly management strategies. A better understanding of the genetic variability in cassava odour constituents and emissions under field conditions may accelerate the development of more resistant cassava varieties.

Abstract
Tyrosine metabolism has an intense role in the synthesis of neurotransmitters. Our study used an untargeted, sportomics-based analysis of urine samples to investigate changes in metabolism during a soccer match in 30 male junior professional soccer players. Samples were collected before and after the match and analyzed using liquid chromatography and mass spectrometry. Results showed significant changes in tyrosine metabolism. Exercise caused a downregulation of the homogentisate metabolites 4-maleylacetoacetate and succinylacetone to 20% (p = 4.69E-5) and 16% (p = 4.25E-14), respectively. 4-Hydroxyphenylpyruvate, a homogentisate precursor, was found to be upregulated by 26% (p = 7.20E-3). The concentration of hawkinsin and its metabolite 4-hydroxycyclohexyl acetate increased ~six-fold (p = 1.49E-6 and p = 9.81E-6, respectively). Different DOPA metabolism pathways were also affected by exercise. DOPA and dopaquinone increased four-to six-fold (p = 5.62E-14 and p = 4.98E-13, respectively). 3-Methoxytyrosine, indole-5,6-quinone, and melanin were downregulated from 1 to 25%, as were dopamine and tyramine (decreasing to up to 5% or 80%; p= 5.62E-14 and p = 2.47E-2, respectively). Blood TCO2 decreased as well as urinary glutathione and glutamate (40% and 10% respectively) associated with a two-fold increase in pyroglutamate. Our study found unexpected similarities between exercise-induced changes in metabolism and the inherited disorder Hawkinsinuria, suggesting a possible transient condition called exercise-induced hawkinsinuria (EIh). Additionally, our research suggests changes in DOPA pathways may be involved. Our findings suggest that soccer exercise could be used as a model to search for potential countermeasures in Hawkinsinuria and other tyrosine metabolism disorders.

Abstract
Schinus terebinthifolius Raddi has been extensively studied due to its antioxidant, anti-inflammatory and antibiotic properties. Recently, its seeds have been tested against some insect pests as an insecticide, repellent and antifungal agent. Microencapsulation by spray-drying is widely used in the food and drug industries, as well as in the microencapsulation of essential oils, since it protects the oils against several effects, such as oxidation and thermal degradation, thus optimising its use. The aim was to microencapsulate S. terebinthifolius essential oil by spray-drying maltodextrin and arabic gum as encapsulating agents and SiO2 as a colloidal adjuvant. The morphology of the microcapsules was analysed by scanning electron microscopy (SEM), which evidenced mainly regular spherical-shaped particles with sizes between 5 and 10 µm. The thermal stability was studied by thermogravimetric analysis-differential scanning calorimetry (TGA-DSC), and the microcapsules were stable at temperatures up to 200°C. The microencapsulating agents and the spray-drying technique produced microcapsules capable of protecting the essential oil against external effects, such as thermal degradation.

Abstract
A novel baculovirus observed to infect Automeris liberia (Cramer) (bullseye moth) is here described. Caterpillars of A. liberia with symptoms of viral infection were collected from African oil palm plantations in Tailândia, PA, Brazil. Macerated caterpillars were then offered to caterpillars of Automeris cinctistriga (Felder & Rogenhoper), leading to viral symptoms and death before pupation. A transmission electron microscope was used for virus ultrastructural identification. The presence of viral occlusion bodies (OBs) containing multiple nucleocapsids was observed and such features are compatible with Alphabaculovirus (Baculoviridae). Molecular detection by PCR with primers for polyhedrin gene (polh) and for late expression factor-8 gene (lef-8), confirmed that this isolate belonged to Alphabaculovirus genus. To our knowledge, this is the first record of a baculovirus isolated from or associated to Automeris. The name Automeris liberia nucleopolyhedrovirus (AuliNPV) is proposed for the new virus.

Abstract
RESUMO: Dentre os métodos de controle da propagação da doença do anel-vermelho, o uso de feromônios associado às armadilhas com alimentos tem se mostrado eficiente na captura do inseto-praga. O feromônio utilizado é denominado como Rincoforol e é disponibilizado em microtubos. Estudos estão em desenvolvimento para aplicar o agente de captura em matrizes sólidas. Nesse contexto, o presente trabalho foi realizado a fim de avaliar a capacidade adsortiva do carvão ativado do endocarpo do coco de dendê na incorporação do Rincoforol para liberação controlada do feromônio em campo. Para isso, foi realizado um planejamento experimental completo (23) a fim de avaliar a influência do uso de estabilizante junto ao feromônio, da granulometria do carvão ativado e do número de furos do sachê no processo de liberação, obtendo como resposta a perda de massa. Verificou-se que a condição que favorece a liberação controlada do feromônio, ao comparar com a liberação realizada em eppendorf, foi o uso do Rincoforol formulado (com estabilizante) adsorvido em carvão com menor granulometria (35 < ᴓ < 28 mesh) e sachê com 5 furos, condição encontrada no experimento de número 3, o qual apresentou uma menor perda de massa.

Abstract
The sugarcane hairy borer, Hyponeuma taltula (Schaus, 1904), attacks the base of sugarcane and causes the death of the apical bud, a symptom known as "dead heart." In recent years, there has been significant infestation in Brazilian sugarcane crops. With the purpose of finding methods for controlling and/or monitoring the pest for the sustainable cultivation of sugarcane, we characterized the mating behavior of H. taltula and confirmed the release of a sex pheromone by this insect. Sexual activity was observed between the second and ninth hour of scotophase, during which female calling caused the onset of male courtship behaviors and increased their frequency. An ethogram was built showing that males perform seven observable steps: (1) wing flapping, (2) walking with wing flapping, (3) flying, (4) flying towards the female, (5) landing near the female and walking around her, (6) attempting copulation, and (7) copulation (mating). Female sex gland extracts also triggered attraction and male courtship behaviors. These results thus confirm that the female abdominal gland produces a sex pheromone and that the presence of this pheromone in the air is needed to initiate the male courtship sequence. The sexual behavior of H. taltula is compatible with control and/or monitoring methods using female sex pheromones.

Abstract
ABSTRACT: The weevil Ozopherus muricatus Pascoe, 1872 (Coleoptera: Curculionidae) is already considered a pest in Brazil for açaí palm (Euterpe oleracea Mart.) plantations. Its presence has become more frequent and caused significant reduction in the production of açaí fruit. Studies on the biology of this insect pest are still scarce, hindering its management. For studies on pheromones, for instance, it is essential to correctly identify the sex of the insect. The objective of this study was to evaluate the existence of sexual dimorphism in pupae and adults of O. muricatus in order to allow the identification of males and females. Larvae, pupae and adults were collected from açaí plantations and kept in biochemical oxygen demand (BOD) type incubation chambers. Adults and pupae were examined under a stereomicroscope, and dimorphism was determined through observation of external morphological characteristics. In addition, adults were dissected in order to observe genitalia and confirm the sex of specimens. In the pupae, sexual dimorphism was characterized by the presence of two protuberances in the terminal ventral region of the abdomen of females, which were absent in males. In adults, sexual dimorphism was also observed, based on the final abdominal segments. In males, it was possible to see all eight abdominal tergites, while in females tergite VIII is covered by tergite VII. Thus, the sexual dimorphism present in the morphological characteristics of O. muricatus allows the distinction between males and females of this species.

Abstract
CONTEXT Propolis has promising biological activities. Propolis samples from the Northeast of Bahia, Brazil - sample A from Ribeira do Pombal and B, from Tucano - were investigated, with new information regarding their biological activities. OBJECTIVE This paper describes the chemical profile, antioxidant, anti-glycation and cytotoxic activities of these propolis samples. MATERIAL AND METHODS Ethanol extracts of these propolis samples (EEP) and their fractions were analyzed to determine total phenolic content (TPC); antioxidant capacity through DPPH•, FRAP and lipid peroxidation; anti-glycation activity, by an in vitro glucose (10 mg/mL) bovine serum albumine (1 mg/mL) assay, during 7 d; cytotoxic activity on cancer (SF295, HCT-116, OVCAR-8, MDA-MB435, MX-1, MCF7, HL60, JURKAT, MOLT-4, K562, PC3, DU145) and normal cell lines (V79) at 0.04-25 μg/mL concentrations, for 72 h. The determination of primary phenols by ultra high-pressure liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS) and volatile organic compounds content by gas chromatography-mass spectrometry (GC-MS) were also performed. RESULTS The EEP polar fractions exhibited up to 90% protection against lipid peroxidation. The IC50 value for anti-glycation activity of EEP was between 16.5 and 19.2 μg/mL, close to aminoguanidine (IC50 = 7.7 μg/mL). The use of UHPLC-MS/MS and GC-MS allowed the identification of 12 bioactive phenols in the EEP and 24 volatile compounds, all already reported. CONCLUSIONS The samples present good antioxidant/anti-glycation/cytotoxic activities and a plethora of biologically active compounds. These results suggest a potential role of propolis in targeting ageing and diseases associated with oxidative and carbonylic stress, aggregating value to them.

Abstract
The stable fly, Stomoxys calcitrans (Diptera: Muscidae), is a worldwide pest of livestock. Recent outbreaks of stable flies in sugarcane fields in Brazil have become a serious problem for livestock producers. Larvae and pupae found inside sugarcane stems after harvesting may indicate that stable flies use these stems as potential oviposition or larval development sites. Field observations suggest that outbreaks of stable flies are associated with the vinasse and filter cake derived from biomass distillation in sugarcane ethanol production that are used as fertilizers in sugarcane fields. Adult stable flies are attracted to vinasse, which appears to present an ideal larval development site. The primary goal of the present study is to demonstrate the role of vinasse in influencing the sensory physiological and behavioural responses of stable flies, and to identify its associated volatile attractant compounds. Both laboratory and field studies showed that vinasse is extremely attractive to adult stable flies. Chemical analyses of volatiles collected revealed a wide range of carboxylic acids, alcohols, phenols and aldehydes as potential attractant compounds. These newly identified attractants could be used to develop a tool for the attractant-baited mass trapping of stable flies in order to reduce infestations.
