13. Morfología del cibario en subgéneros de Psorophora Robineau-Desvoidy (Diptera: Culicidae)
We describe the cibarial morphology in eight Psorophora species Robineau-Desvoidy: Ps. (Grabhamia) cingulata (Fabricius), Ps. (Gra.) confinnis (Lynch Arribálzaga), Ps. (Janthinosoma) ferox (Humboldt), Ps. (Jan.) albipes (Theobald), Ps. (Jan.) cyanescens (Coquillett), Ps. (Psorophora) lineata (Humboldt), Ps. (Pso.) cilipes (Fabricius), y Ps. (Pso.) ciliata (

14. Morphometry of the antenna, number and distribution of structures in sensory olfactive bees Euglossina and Meliponina (Hym: Apidae) / MORFOMETRIA DA ANTENA, NÚMERO E DISTRIBUIÇÃO DE ESTRUTURAS SENSORIAIS OLFATIVAS EM ABELHAS EUGLOSSINA E MELIPONINA (HYM: APIDAE)
Most part of the external sensory receptaclles known are located in the antennal flagellate: sensilla placodea (olfactory discs, D.O.), basiconica, trichodea (cerdas), coeloconica, ampullaceae and campaniformia. The Apidae bees have been studied on diverse aspects, the external morphology, among which has call the attention for its importance is the bee ante

15. Morphometry of the antenna, number and distribution of structures in sensory olfactive bees Euglossina and Meliponina (Hym: Apidae) / MORFOMETRIA DA ANTENA, NÚMERO E DISTRIBUIÇÃO DE ESTRUTURAS SENSORIAIS OLFATIVAS EM ABELHAS EUGLOSSINA E MELIPONINA (HYM: APIDAE)
No flagelo antenal se encontra a maior parte de receptores sensoriais externos conhecidos: sensilla placodea (discos olfativos, D.O.), basiconica, trichodea (cerdas), coeloconica, ampullacea e campaniformia. Nas abelhas Apidae, têm sido estudadas sob os mais diversos aspectos, a morfologia externa, sendo que um dos caracteres que tem chamado a atenção pel

16. 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

17. Analysis of antenal sensilla patterns of Rhodnius prolixus from Colombia and Venezuela
Antennal sensilla patterns were used to analyze population variation of domestic Rhodnius prolixus from six departments and states representing three biogeographical regions of Colombia and Venezuela. Discriminant analysis of the patterns of mechanoreceptors and of three types of chemoreceptors on the pedicel and flagellar segments showed clear differentiati

18. Patterns of antenal sensilla of Panstrongylus megistus from three Brazilian states
The objective of the present study was to analyze and describe the phenotype of the antennal sensilla of Panstrongylus megistus, one of the epidemiologically most important species of triatomines in Brazil. Specimens from the Brazilian states of Goiás (GO), Minas Gerais (MG), and Rio Grande do Sul (RS) were compared, based on studies of four types of sensil

19. Morphology of olfactory sensilla and its role in host plant recognition by Neomegalotomus parvus (Westwood) (Heteroptera: Alydidae)
A morfologia externa dos sensilos de adultos de Neomegalotomus parvus (Westw.) (Het.: Alydidae), incluindo poros e pontos permeáveis na cutícula, foi estudada em microscópio eletrônico de varredura, em relação à função olfativa. A evidência comportamental do olfato e a importância dos diferentes segmentos antenais na localização do hospedeiro, e

20. Changes associated with laboratory rearing in antennal sensilla patterns of Triatoma infestans, Rhodnius prolixus, and Rhodnius pallescens (Hemiptera, Reduviidae, Triatominae)
We examined changes in the array of antennal sensilla of three species of Triatominae (Triatoma infestans, Rhodnius prolixus, and R. pallescens) following their establishment for different periods in laboratory culture. In each case, the laboratory colonies were compared with conspecific samples taken directly from the field, by quantitative analysis of the

21. Last instar larva of Trypoxylon (Trypoxylon) maidli Richards (Hymenoptera, Crabronidae), with biological notes on one nest
The last larval instar and the cocoon of Trypoxylon (Trypoxylon) maidli Richards, 1934 are described. This larva is apparently indistinguishable from that of T. clavicerum exiguum Tsuneki, 1956. They can be distinguished from larvae of other species in the subgenus by the following features: integument of body smooth, sensilla on both sensorial area and labr

22. Relationship between antennal sensilla pattern and habitat in six species of Triatominae
In order to determine if habitat similarity is correlated with a similarity of sensilla pattern, we analyzed six species of Triatominae present in two biogeographic regions of Brazil: the "caatinga" and the "cerrado". In broad terms Triatoma infestans (cerrado) and T. brasiliensis (caatinga) are found in human domiciles, T. sordida (cerrado) and T. pseudomac

23. The frontal weapon of the termite Armitermes euamignathus Silvestri (Isoptera, Termitidae, Nasutitermitinae)
Frontal weapon is the term used to designate the apparatus consisting of frontal gland and associated structures that participate in the chemical defense of termite soldiers. The ultra structure of the frontal gland and the scanning microscopy of the soldier head was investigated in the termite Amiitermes euamignathus Silvestri, 1901.Campaniform sensilla was

24. Inter-specific and developmental differences on the array of antennal chemoreceptors in four species of triatominae (Hemiptera: Reduviidae)
The aim of the work was to investigate the pattern of chemoreceptor sensilla in adults and fifth stage nymphs of Rhodnius prolixus, R. neglectus, Triatoma infestans and T. sordida in order to study differences and similarities between genera and species. Three types of sensilla were analyzed by light microscopy: thin-walled trichoidea, thick-walled trichoide
