Identification of Defensive Compounds in Metathoracic Glands of Adults of the Stink Bug Dichelops melacanthus (Hemiptera: Pentatomidae)
Os conteúdos das glândulas metatorácicas de insetos adultos do percevejo Dichelops melacanthus (Hemiptera: Pentatomidae) foram analisados. Os compostos de defesa foram identificados combinando as técnicas de cromatografia gasosa (CG), cromatografia gasosa acoplada à espectrometria de massas (CG-EM) e por comparação de seus índices de retenção com os de compostos padrões. Tridecano foi o compone...
متن کاملNatural History of Tropical Parasitoid Wasps
The order Hymenoptera currently includes the impressive number of more than 115000 known species. The tropical hymenopteran fauna, however, is poorly known and this number probably represents just a small fraction of the real richness of the group. A great part of the species within Hymenoptera is composed of parasitoids, animals that exploit other organisms to death in order to acquire the foo...
متن کاملTranscriptome-Based Identification of Highly Similar Odorant-Binding Proteins among Neotropical Stink Bugs and Their Egg Parasitoid
Olfaction plays a fundamental role in insect survival through resource location and intra and interspecific communications. We used RNA-Seq to analyze transcriptomes for odorant-binding proteins (OBPs) from major stink bug pest species in Brazil, Euschistus heros, Chinavia ubica, and Dichelops melacanthus, and from their egg parasitoid, Telenomus podisi. We identified 23 OBPs in E. heros, 25 OB...
متن کاملThe chemical volatiles (semiochemicals) produced by neotropical stink bugs (Hemiptera: Pentatomidae).
In recent years the growing concern about environmental changes and how we are using the natural resources have triggered a search for natural products as alternatives to synthetic pesticides. The stink bugs produce a wide variety of chemical compounds (semiochemicals) that show potential to manage these insects. The stink bugs Chinavia impicticornis (Stål), C. ubica (Rolston), Dichelops melaca...
متن کاملNeuroethology of Parasitoid Wasps
Predators as diverse as snakes, scorpions, spiders, insects and snails manufacture venoms to incapacitate their prey. Most venoms contain a cocktail of neurotoxins and each neurotoxin is designed to target specific receptors in the nervous and muscular systems. Most neurotoxins act peripherally and interfere with the ability of the prey's nervous system to generate muscle contraction or relaxat...
