1. Gross morphology and ultrastructure of the female reproductive system of Diaphorina citri (Hemiptera: Liviidae)
The morphological traits of the female reproductive system of Diaphorina citri were examined in detail. Diaphorina citri has telotrophic ovaries with ovarioles organized as a "bouquet", displaying a rudimentary terminal filament and a syncytial tropharium. The vitellarium carries a single growing oocyte at each maturation cycle, which is connected with the t

2. O extrato de neem (Azadirachta indica) causa alterações no desenvolvimento ninfal, no aparelho reprodutor e sistema digestivo do predador Supputius cincticeps (Heteroptera: Pentatomidae)? / Does the neem (Azadirachta indica) extract cause nymphal development, the reproductive system and digestive tract of the predator Supputius cincticeps (Heteroptera: Pentatomidae)?
The subfamily Asopinae presents important species of predators, as Supputius cincticeps (Stal) (Hemiptera: Pentatomidae). These stinkbug present potential for the biological control of Lepidoptera defoliators in eucalyptus plantations in Brazil.Botanical insecticides, mainly neem (Azadirachta indica), are alternative for the control of herbivore insects of a

3. Herbivory affects ovarian development in the zoophytophagous predator Brontocoris tabidus (Hetereoptera, Pentatomidae).
The effect of prey-based and combination prey and plant-based diets [Tenebrio molitor pupae alone; T. molitor pupae and Eucalyptus cloeziana plants; T. molitor pupae and Eucalyptus urophylla plants; and T. molitor pupae and Psidium guajava (guava) plants] on the morphometry of the ovary of Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) was analyz

4. Desenvolvimento ovariano e influência da cópula na maturação dos ovários de Diaphorina citri Kuwayama (Hemiptera: Psyllidae)
As many other insects with a restricted diet, the citrus psyllid Diaphorina citri Kuwayama, which vector the causing agent of the Huanglongbing, the bacteria Candidatus Liberibacter spp., is intimately associated with symbiotic microorganisms. These mutualist symbionts play a key role on their host nutritional ecology, and are vertically transmitted to the p

5. Sequence and expression pattern of the germ line marker vasa in honey bees and stingless bees
Queens and workers of social insects differ in the rates of egg laying. Using genomic information we determined the sequence of vasa, a highly conserved gene specific to the germ line of metazoans, for the honey bee and four stingless bees. The vasa sequence of social bees differed from that of other insects in two motifs. By RT-PCR we confirmed the germ lin

6. Modifications of reproductor system of Brontocoris tabidus (Heteroptera: Pentatomidae) after exposition to deltamethrin / Modificações do aparelho reprodutor de Brontocoris tabidus (Heteroptera: Pentatomidae) após exposição à deltametrina
Beneficial insects such as Pentatomidae predators can be negatively or positively affected by insecticides. This research studied the impact of the deltamethrin Decis 25CE, with the concentrations of 0,0165%, 0.033% e 0.066%, representing the treatments T1, T2 and T3, respectively, on the reproductive system of males and females of the predator Brontocoris t

7. Histomorphometric evaluation of the female reproductive system of Tropidacaris collaris (Stoll,1813) (Orthoptera: Romaleidae) submitted to three photoperiods / Avaliação histomorfométrica do aparelho reprodutor feminino de Tropidacris collaris (Stoll,1813) (Orthoptera : Romaleidae) submetido a três fotoperíodos
In Brazil, the presence and the increase of the population of grasshoppers are linked, certainly, to the deforestation and to the new types of manipulation of agroforestry cultures, implanted in the cerrado and other regions. Among the species of grasshoppers of economic importance, the Tropidacris collaris (Stoll, 1813) (Orthoptera: Romaleidae) is highlight

8. Estudo da fauna de Anacroneuria (Plecoptera: Perlidae) na Bacia Hidrográfica do Rio dos Sinos, Estado do Rio Grande do Sul, com dados sobre a fecundidade de Anacroneuria trimacula / Study of the fauna of Anacroneuria (Plecoptera: Perlidae) from the Rio dos Sinos basin, and data on the fecundity of Anacroneuria trimacula
Stoneflies are ancient and relatively primitive insects. Plecopterans number about 2000 species belonging to 16 families. In Brazil two families are known, Gripopterygidae and Perlidae. Two genera of Perlidae have been reported from Rio Grande do Sul State, Anacroneuria and Kempnyia. The intention of this work was to inventory the Anacroneuria fauna in the S

9. Immature stages, internal morphology and morphometry of Platyscytus decempunctatus (Carvalho, 1945) (Heteroptera: Miridae) / Estágios imaturos, morfologia interna e morfometria de Platyscytus decempunctatus (Carvalho, 1945) (Heteroptera: Miridae)
Platyscytus decempunctatus (Heteroptera: Miridae) is a small mirid (three to four mm) found in plants of Solanum cernuum Vell. (Solanaceae), where it develops throughout its life cicle. The study of the insect internal morphology describes the basic internal tracts of the salivary glands, the midgut, the male and female reproductive structures and the Malpig

Biology of the leaf gall inducer Neotrioza tavaresi Crawford, 1925 (Hemiptera, Psyllidae) on strawberry guava tree (Psidium cattleianum). A field study was conducted in Curitiba region, State of Paraná, southern Brazil, to describe the life cycle of Neotrioza tavaresi Crawford, 1925, a leaf galling insect in strawberry guava trees (Psidium cattleianum).

11. Determinação das castas em Scaptotrigona postica (Latreille) (Hymenoptera, Apidae, Meliponini): diferenciação do ovário
Both castes of Scaptotrigolia postica (Latreille, 1804) possess four ovarioles in each ovary. Queen and workers have the same ovarian development during the larvallife, but in lhe late larval stage the queen ovary beco me larger. During pupation a higher rate of cell division is observed in queen ovarioles and a higher rale of cell death in workers. Newly em

12. Patriline effect on the activation of the ovary and production of drones in queenless workers of Apis mellifera. / Efeito da linhagem paterna sobre a ativação dos ovários e produção de zangões em operárias de Apis mellifera deixadas órfãs
Rainhas de Apis mellifera acasalam com 10-20 zangões. O parentesco médio entre as operárias filhas da rainha, portanto, atinge valores bastante divergentes entre operárias da mesma patrilínea (r=0,75) e operárias de diferentes patrilíneas (r=0,29), o que deve resultar em conflitos de interesse no que diz respeito à reprodução. Neste estudo abordamo
