13. Estrutura e ultra-estrutura das glândulas salivares de Cimex hemipterus (Fabricius, 1803) (Hemiptera: Cimicidae) / Structure and ultrastructure of the salivary glands of Cimex hemipterus (Fabricius, 1803) (Hemiptera: Cimicidae)
Cimex hemipterus is a hematophagous insect that can be an experimental host of the Trypanosoma cruzi and may play a role as vector of Chagas disease. This work analyzed the structure of the salivary glands of C. hemipterus. Adults were dissected and the salivary glands were analyzed in light microscopy and transmission electron microscopy. The secretory port

14. Identificação e quantificação de hemócitos de fêmeas ingurgitadas de Boophilus microplus inoculados com fungos Metarhizium anisopliae, Beauveria bassiana, Penicillium corylophilum e Fusarium oxysporum. / Identification and quantification of hemocytes obtained from engorged females of Boophilus microplus (Canestrini, 1887) (Acari: Ixodidae) inoculated with Metarhizium anisopliae, Beauveria bassiana, Penicillium corylophilum and Fusarium oxysporum
Biological control of the tick Boophilus microplus with Metarhizium anisopliae and Beauveria bassiana has been evaluated by several researchers. The selection of specimens resistant to chemical products is a mechanism used by arthropods for survival and maintenance in the environment. It is already known how fungi penetrate the host and their pathogenic pote

15. Efeitos do substrato e da densidade populacional sobre as atividades comportamentais e níveis de homócitos em relação à densidade em Litopenaeus vannamei (BOONE, 1931)
Carciniculture in Brazil occupies world-wide prominence due to shrimp culture, and the state of Rio Grande do Norte has presented the best results in the culture of the Litopenaeus vannamei in the last decade. This species has been shown to adapt easily to different environments and is between the five most cultivated penaeids of the world. The ponds are usu

16. Transformação genética de maracujá amarelo visando resistência à Xanthomonas axonopodis pv. passiflorae / Genetic transformation of yellow passion fruit to confer resistance to Xanthomonas axonopodis pv. passiflorae
Bacterial spot disease caused by Xanthomonas axonopodis pv. passiflorae is a serious problem in many passion fruit production areas in Brazil, especially if associated with anthracnose. Genetic transformation provides an alternative for obtaining resistant plants. Bactericide proteins such as attacins, found in the haemolymph of insects, have been used to co

17. Action of Trypanosoma rangeli in infections with virulent Trypanosoma cruzi populations
In experimental murine infections with Trypanosoma rangeli it has been observed development immune response to Trypanosoma cruzi. The aim of the present work was to analyze the result of antigenic stimuli and the protective effect with T. rangeli in T. cruzi infections. Mice groups immunized with metacyclic trypomastigotes of T. rangeli (Choachí-2V strain),

18. Haemolymph electrophoretic pattern of Ascia monuste orseis larvae (Lepidoptera: pieridae) parasitized by Cotesia glomerata (Hymenoptera: braconidae)
Cotesia glomerata is a natural enemy of the vegetable plague Ascia monuste orseis and preferably parasites 2nd, 3rd and 4th instar larvae. Parasitism effects on the haemolymph protein profile of Ascia monuste orseis larvae from the 2nd to 7th days were analyzed both qualitatively and quantitatively by SDS-PAGE and Coomassie-Blue binding methods. Quantitative

19. Ultra-estrutura de glândulas abdominais tegumentares em Oxaea flavescens (Hymenoptera, Andrenidae, Oxaeinae)
The sternal glands of the abdomen of Oxaea flavescens (Klug, 1807) consist of class III glandular cells around a reservoir constituted by branched folds of the intersegmental membrane of segments III, IV and V. The gland cells are rich in rough endoplasmic reticulum and produce a secretion with mucous aspect. The treatment with oxidated osmium and ruthenium

20. Ação da hidrocortisona no desenvolvimento de Schistosoma mansoni Em biomphalaria glabrata
Hydrocortisone (cortisol) is the main example of a drug which presents antiinflammatory and immunosupressive efTects in mammals like other compounds as corticosteroids, suprarenal hormones with steroid formation or any others with similar activities. Its main activity is on the cell defence and is used in the infection and allergy cases best inhibiting pri

21. Studies on haemolymph nodes. IV. Comparison of the route of entry of carbon particles into parathymic nodes after intravenous and intraperitoneal injection.
Haemolymph nodes are found in certain mammals including man. In the rat they are located near the kidneys, spleen and thymus. A distinctive feature is that their sinuses contain numerous erythrocytes. For renal and splenic haemolymph nodes, the erythrocytes appear to be extrinsic in origin, entering the node via its afferent lymphatics (Hogg et al. 1982; Abb

23. Insect immunity: developmental and inducible activity of the Drosophila diptericin promoter.
Diptericins are 9 kDa inducible antibacterial peptides initially isolated from immune haemolymph of Phormia (Diptera). Following the isolation of a Drosophila cDNA encoding a diptericin homologue, we have now cloned a genomic fragment containing the Drosophila diptericin gene. To dissect the regulation of this gene, we have transformed flies with a fusion ge

24. Scab formation and wound healing of plant tissue by soldier aphid
In the social aphid Nipponaphis monzeni, a unique gall-repairing behaviour has been known: when a hole is made on the gall, many soldier nymphs discharge body fluid on the breach, which promptly solidifies and plugs the hole. Here, we experimentally investigated the subsequent fate of repaired galls and their inhabitants. Irrespective of natural repair by so
