13. Sex pheromone and period gene characterization of Lutzomyia longipalpis sensu lato (Lutz & Neiva) (Diptera: Psychodidae) from Posadas, Argentina
Lutzomyia longipalpis s.l. is the primary vector of Leishmania (L.) infantum in the New World. In this study, male Lutzomyia longipalpis specimens from Posadas, Argentina were characterized for two polymorphic markers: the male sex pheromone and the period (per) gene. The male sex pheromone was identified as (S)-9-methylgermacrene-B, the same compound produc

14. Reproductive behaviour of Crocidosema (=Epinotia) aporema (Walsingham) (Lepidoptera: Tortricidae): temporal pattern of female calling and mating
Crocidosema aporema (Walsingham) is a major pest of legumes in the southern cone of Latin America. The mating behaviour of two allopatric populations (Uruguay and Brazil) of C. aporema kept in captivity was studied by observing the posture of calling females, the temporal pattern of pheromone emission and mating, and the response of males to calling females

15. Efeito de fatores endógenos na percepção química de Grapholita molesta(Busck) (Lepidoptera: Tortricidae) ao feromônio sexual
The oriental fruit moth, Grapholita molesta (Busck), stands out as one of the most important pest in Rosaceae orchards in Brazil. During feeding, caterpillars bore into shoots, branches and fruits, impairing the commercial production. This work aimed to study the effect of endogenous factors in the chemical perception and in the species chemotactic behavior,

17. More about the role of 2,6-dichlorophenol in tick courtship: identification and olfactometer bioassay in Amblyomma cajennense and Rhipicephalus sanguineus
This study aimed to identify 2,6-dichlorophenol (2,6-DCP) in Amblyomma cajennense and to evaluate its role in A. cajennense and Rhipicephalus sanguineus courtship. Hexanic extract from attractive females was purified by solid phase extraction and the phenol was identified by the single ion monitoring method using GC/MS. In an olfactometer, the responses of A

18. 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

21. Reproductive behavior and sex pheromone identification of Pseudaletia sequax (Lepidoptera: Noctuidae) / Comportamento reprodutivo e identificação de feromônio sexual de Pseudaletia sequax (Lepidoptera: Noctuidae)
The effects of pupal period and age on calling behavior of virgin females of Pseudaletia sequax were determined. Larvae were reared on artificial diet. Calling behavior of groups of females of similar age of pupation was observed every 10 minutes for six days at reversed photoperiod. Females were considered calling when they had assumed a characteristic posi

22. Isolamento, identificação, síntese e avaliação de campo do feromônio sexual do minador-dos-citros, Phyllocnistis citrella Stainton, 1856 (Lepidoptera: Gracillariidae) / Isolation, identification, synthesis and field evaluation of the sex pheromone from the citrus leafminer, Phyllocnistis citrella Stainton, 1856 (Lepidoptera: Gracillariidae)
The objectives of this work were to isolate, identify, and synthesize the sex pheromone of Phyllocnistis citrella Stainton, 1856 (Lepidoptera: Gracillariidae), as well as to evaluate its efficiency in field conditions, to rationalize the control of this pest within a Citrus Integrated Pest Management scope. The research was developed at the Insect of Biology

23. Contribution to the studyof chemical comunication in Lutzomyia longipalpis AND Lutzomyia cruzi (Diptera: Psychodidae: Phlebotominae) / Contribuição ao estudo da comunicação química em Lutzomyia longipalpis e Lutzomyia cruzi (Diptera: Psychodidae: Phlebotominae)
Ultrastructural cytochemistry of sex pheromone gland cells in abdominal tergites of Lutzomyia cruzi males showed the presence of large amounts of lipid inclusions, peroxisomes, mitochondria and endoplasmic reticulum profiles. In L. longipalpis it was demonstrated that these lipid inclusions appear in the gland cell cytoplasm about 9 hours after adult emergen
