Genotypic virulence profiles and mobile genetic elements related to invasiveness in Neisseria gonorrhoeae strains Open
Introduction: The increasing incidence of Neisseria gonorrhoeae (NG) has become a global health threat due to drug resistance and potentially invasive disease. Few studies in Brazil have analyzed the presence of resistance genes and its co…
Pheromone release and perception, and fertility of insecticide-exposed cotton boll weevils (Anthonomus grandis grandis) Open
The objective of this work was to evaluate the effects of sublethal exposure to the insecticides malathion and beta-cyfluthrin on the pheromone perception and emission by the cotton boll weevil (Anthonomus grandis grandis Boheman (Coleopte…
Bait type affects the diversity assessment of cetoniid beetles in the Brazilian Cerrado Open
Cetoniidae (Coleoptera), known as flower and fruit beetles, form a diverse group, feed on nectar, pollen, plant exudates, and are highly attracted to fermented fruits. To evaluate their diversity in natural and agricultural areas, traps ba…

Protective Geometry and Reproductive Anatomy as Candidate Determinants of Clutch Size Variation in Pentatomid Bugs Open
Many animals lay their eggs in clusters. Eggs on the periphery of clusters can be at higher risk of mortality. We asked whether the most commonly occurring clutch sizes in pentatomid bugs could result from geometrical arrangements that max…

Host‐marking pheromone of the South American fruit fly <i>Anastrepha fraterculus</i> and cross‐recognition by the Mediterranean fruit fly <i>Ceratitis capitata</i> (Diptera: Tephritidae) Open
Following oviposition, females of many fruit flies deposit on the fruit surface a host‐marking pheromone (HMP) that can deter oviposition by conspecifics and heterospecifics, thereby minimizing overexploitation of hosts. We describe the ov…

Neotropical maize genotypes with different levels of benzoxazinoids affect fall armyworm development Open
Plants are equipped with various defensive attributes against herbivores, including volatile and nonvolatile compounds. In maize plants, benzoxazinoids mediate resistance against some herbivores, with the most abundant being (2 R )‐2‐β‐D‐g…
Stink Bug Communication and Signal Detection in a Plant Environment Open
Plants influenced the evolution of plant-dwelling stink bugs’ systems underlying communication with chemical and substrate-borne vibratory signals. Plant volatiles provides cues that increase attractiveness or interfere with the probabilit…
