1. Reproductive behaviours and host plant selection mediated by semiochemicals in Neoleucinodes elegantalis (Lepidoptera: Crambidae) / Comportamento reprodutivo e seleção de hospedeiro mediada por semioquímicos em Neoleucinodes elegantalis (Lepidoptera: Crambidae)
The searching behaviour in insects is important to acquire food, meeting mates, oviposition sites location and protect the insects against predators. Thus, the majority of herbivorous insects select their host plant and, in particular, the plants part, which it will feed and oviposit on, using, among other tools, host plants semiochemicals. This paper aims:

2. Experimentos sobre a influência de Chaoborus brasiliensis (Diptera: Chaoboridae) sobre a migração vertical de microcrustáceos do Lago Monte Alegre, Brasil
O objetivo deste trabalho foi avaliar se a migração vertical dos microcrustáceos do Lago Monte Alegre é relacionada aos predadores invertebrados, nomeadamente larvas de Chaoborus brasiliensis. A hipótese testada no experimento foi a de que o comportamento migratório da presa seria dependente do contato físico com as larvas de Chaoborus ou dos "kairomo

3. Are light traps baited with kairomones effective in the capture of Lutzomyia longipalpis and Lutzomyia intermedia? An evaluation of synthetic human odor as an attractant for phlebotomine sand flies (Diptera: Psychodidae: Phlebotominae)
Phlebotomine sand flies are often captured with human bait and/or light traps, either with or without an animal bait. More recently, synthetic attractants have been used as bait in traps to improve the capture of phlebotomine sand flies as well as other insects of medical and veterinary importance. The aim of the present study was to evaluate the effects of

4. Síntese do feromônio sexual e respostas eletrofisiológicas frente ao óleo essencial de Psidium guajava de Tryrinteina arnobia / SYNTHESIS OF THE SEX PHEROMONE AND ELECTROPHYSIOLOGICAL RESPONSES TOWARDS THE Psidium guajava ESSENTIAL OIL OF Thyrinteina arnobia
The study of semiochemicals involves the knowledge of different interaction levels between organisms and allows us to understand communication mechanisms and the action of specific compounds in the insect behavior. The eucalyptus-brown-looper, Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae) is considered an important pest in Brazil for native pl

5. Cucurbitacins as kairomones for diabroticite beetles
The characteristic bitter substances of the Cucurbitaceae act as kairomones for a large group of diabroticite beetles (Chrysomelidae, Galerucinae, Luperini), promoting host selection and compulsive feeding behavior. These beetles (e.g., Diabrotica undecimpunctata howardi) respond to as little as 1 ng of cucurbitacin (Cuc) B on thin-layer plates by arrest and

6. Olfactory receptors in the melon fly Dacus cucurbitae and the oriental fruit fly Dacus dorsalis
Male melon flies (Dacus cucurbitae) from a colony in Hawaii were evaluated for limit of response to the olfactory stimulant raspberry ketone and to more than 40 related molecules. The results were compared with the limits of response of oriental fruit flies (Dacus dorsalis) under identical conditions. The nature of the response of the two species to attracti

7. An acoustic microscopy technique reveals hidden morphological defenses in Daphnia
Inducible defenses are common strategies for coping with the selective force of predation in heterogeneous environments. In recent years the conspicuous and often dramatic morphological plasticity of several waterflea species of the genus Daphnia have been found to be inducible defenses activated by chemical cues released by predators. However, the exact def
