2. Intra-puparial development of the Cochliomyia macellaria and Lucilia cuprina (Diptera, Calliphoridae)
ABSTRACT The intra-puparial development of the blowflies Cochliomyia macellaria (n = 310) and Lucilia cuprina (n = 470), was studied under controlled conditions in laboratory. The 3rd instar larvae were reared until they stopped feeding, and the pre-pupae were separated according to the size in larval length and degree of pigmentation and of the cuticle. We

3. Abundance and distribution of Portunidae larval phases (Crustacea: Brachyura) in the estuarine and coastal region of the Patos Lagoon, southern Brazil
ABSTRACT: The abundance and distribution of larval phases of the Portunidae found in the estuary of the Patos Lagoon and the coastal region were studied during two years (1995 and 1999). A conical net (165 cm long, 60 cm mouth, and 330 µm mesh) equipped with a flowmeter was towed for three minutes at 2 knots at six stations within the estuary and four stati

4. The relevance of age and nutritional status on the mating competitiveness of medfly males (Diptera: Teprhitidae)
Results of previous investigations trying to ascertain which physiological factors are more important to the mating success of medfly males are controversial. In part, this controversy owes to the fact that each factor was evaluated by an independent study using different experimental designs and populations. In the present study we compare the roles of age

5. Tadpoles of the High-Andean Hyloxalus subpunctatus (Anura: Dendrobatidae) with description of larval variation and species distinction by larval morphology
This study redescribes the tadpoles of Hyloxalus subpunctatus (Anura: Dendrobatidae) based on larvae from the type locality and over most of its geographic range, including all stages of ontogenetic development. I describe tadpoles in the three developmental phases: (1) back-riding tadpoles, (2) free-swimming tadpoles, (3) froglets or individuals in metamorp

6. Aspectos bioecológicos do coró-das-hortaliças Aegopsis bolboceridus (Thomson) (Coleoptera: Melolonthidae) no cerrado do Brasil Central.
ABSTRACT: Insects commonly well-known as white grubs are the larval phase of beetles that belong to the Melolonthidae (Coleoptera). This family contains an expressive number of insect species that have different bioecological functions in the agroecosystems in the adult and immature phases. In four of five trophic levels, they are primary and secondary consu

7. Biology and morphology of Molippa cruenta (Lepidoptera: Saturniidae) in the laboratory
The goal of this contribution was to study the biology and morphology of all developmental stages of Molippa cruenta (Walker, 1855), a member of Hemileucinae (Saturniidae), endemic to southern Brazil and northeastern Argentina. Daily observations were carried out on individuals reared under controlled temperature (25 ± 1ºC), relative humidity (70 ± 10%) a

8. Caracterização do desenvolvimento ontogênico inicial de Anchoviella vaillanti (Steindachner, 1908)
This study aimed to describe morphologically the ontogenetic initial development of the freshwater anchovy, Anchoviella vaillanti, which is endemic to the São Francisco river basin. We analyzed 132 specimens (SL = 1,3-51 mm) obtained from hauls made with a 500 μm mesh conical-cylindrical plankton net in quarterly samplings in different stretches of the

9. Biologia reprodutiva da tainha Mugil liza Valenciennes e do Parati Mugil curema Valencienns (Actinopterygii, Mugilidae) na Baia de Sepetiba, RJ, Brasil
The reproductive biology of the mullets Mugil curema and Mugil liza was determined mainly by observing gonad development, size at maturation and fecundity. The objective of this study was to learn about the strategies developed by these species to maintain their exploited populations in an increasingly altered system. It was hypothesized that there are diffe

10. SELETIVIDADE DE INSETICIDAS UTILIZADOS EM CULTURA ALGODOEIRA PARA O PREDADOR Cycloneda sanguinea (LINNAEUS, 1763) (COLEOPTERA, COCCINELLIDAE) / PEDROSO, Elizabeth do Carmo. Insecticides selectivity used in cotton crop to the predator Cycloneda sanguinea (Linnaeus, 1763) (Coleoptera, Coccinellidae). 2008. 93p. Thesis (Master degree in Entomology) â Federal University of Lavras, Lavras, MG.
The preservation of natural enemies in agroecosystems is very important to the pest control and thereat it should opt by the preferential application of selective products. In this way, the objective was evaluate the insecticides effects used in the cotton crop on the eggs, larvae from third-instar, pupae and adults from ladybug Cycloneda sanguinea (Linnaeus
