Intraspecific and interspecific pre-adult competition on the neotropical region colonizer Zaprionus indianus (Diptera: Drosophilidae) under laboratory conditions 53
Galego,Luís Gustavo da Conceição; Carareto,Claudia Marcia Aparecida.
This study analyzes the pre-adult interactions of Zaprionus indianus, a recently-introduced species in Brazil, with two others Drosophilidae under laboratory conditions. The effects of larval residues on the viability and on the developmental time of Z. indianus, Drosophila simulans and D. sturtevanti were used to evaluate pre-adult competitive interactions, conditioning the culture medium with larval residues. Pre-adult interactions between Z. indianus, D. sturtevanti and D. simulans may affect their relative abundance over time, since the viability of Z. indianus was negatively affected by residues of D. sturtevanti, and its residues reduced the viability of D. simulans and the developmental time of both D. simulans and D. sturtevanti.

Influence of different plants substrates on development and reproduction for laboratory rearing of Pseudococcus calceolariae (Maskell) (Hemiptera: Pseudococcidae) 118
Zaviezo,Tania; Cadena,Elizabeth; Flores,M. Fernanda; Bergmann,Jan.
The citrophilus mealybug, Pseudococcus calceolariae, is a polyphagous pest that has a major impact on fruit crops in central Chile, and is of quarantine importance for many markets. To study many control alternatives, it is important to develop efficient rearing protocols. The objective of this work was to determine mealybug development on three different plant substrates: sprouted potatoes, lemon fruits and Butternut squash. Insects were inoculated on the substrates, maintained at 25 °C and in total darkness until completing their development. Every one to 4 days, advancement on the development was checked by counting the exuvia. Mean developmental time for each stage, adult longevity, fecundity and fertility were determined. Preimaginal developmental...

Morphology of the immatures and biology of Chinavia longicorialis (Breddin) (Hemiptera: Pentatomidae) 82
Matesco,Viviana C; Schwertner,Cristiano F; Grazia,Jocelia.
Chinavia longicorialis (Breddin) is recorded only in Brazil, Argentina and Uruguay on host plants of at least three different families. Adults and nymphs were reared under standard controlled conditions (24 ± 1°C; 70 ± 10% RH; 12hL:12hD), and fed on green beans (Phaseolus vulgaris L.). Eggs and first instars of C. longicorialis are very similar to those of other species of Chinavia; however, the presence of orange maculae at the thoracic pleura is exclusive of first instars of C. longicorialis. Third to fifth instars have abdominal maculae divided by pseudo-sutures, a diagnostic feature of C. longicorialis nymphs. Light and dark morphs were observed for third, fourth and fifth instars. Head width measurements did not overlap between consecutive instars....

Aspects of the reproductive behaviour and development of two forensically relevant species, Blaesoxipha (Gigantotheca) stallengi (Lahille, 1907) and Sarcophaga (Liopygia) ruficornis (Fabricius, 1794) (Diptera: Sarcophagidae) 92
Barbosa,Taciano Moura; Cruz,Marília Rafaela Pereira; Pontes,Wendel José Teles; Vasconcelos,Simão Dias.
Abstract We studied aspects of the reproductive behaviour and development of two species of Sarcophagidae (Diptera) of potential forensic importance, Blaesoxipha stallengi (Lahille, 1907) and Sarcophaga ruficornis (Fabricius, 1794), which are dominant in assemblages in dry forests in Northeastern Brazil. We described the behavioural acts associated with courtship and mating and estimated the development time (from egg/larva until adult) - of both species. Description of the reproductive behaviour was based on 50 couples of each species whereas 250 larvae were used for the estimation of the developmental time. A total of 55 successful copula were observed for B. stallengi and 142 for S. ruficornis. Pre-copulatory behaviour differed between the species, as...
