Canine American visceral leishmaniasis and American cutaneous leishmaniasis (ACL) cases have been recorded in Espírito Santo do Pinhal. The aim of this study was to gather knowledge of the sand fly community and its population ecology within the municipality. Captures were made weekly over a period of 15 months in the urban, periurban and rural areas of the municipality, using automatic light traps. A total of 5,562 sand flies were collected, comprising 17 species. The most abundant species were Nyssomyia whitmani and Pintomyia pessoai in the rural area, Lutzomyia longipalpis and Ny. whitmani in the periurban area and Lu. longipalpis in the urban area. The highest species richness and greatest index species diversity were found in the rural area. The similarity index showed that urban and periurban areas were most alike. Lu. longipalpis was found in great numbers during both dry and humid periods. The presence of dogs infected with Leishmania infantum chagasi in the urban area indicates a high risk for the establishment of the disease in the region. A high abundance of Ny. whitmani and Pi. pessoai in the rural and periurban areas indicates the possibility of new cases of ACL occurring in and spreading to the periurban area of Espírito Santo do Pinhal.

Programas que visam o controle biológico precisam ser embasados principalmente em liberações de predadores e parasitóides para tentar minimizar efeitos adversos para o ambiente. Os coleópteros da família Histeridae como predam larvas de dípteros sinantrópicos podem auxiliar no controle das moscas que se desenvolvem em fezes acumuladas. Este trabalho teve como objetivo realizar um levantamento das espécies de histerídeos em granja avícola no município de São João da Boa Vista, estado de São Paulo, verificar seu padrão sazonal de ocorrência e investigar possíveis associações entre as mesmas. As coletas foram realizadas de janeiro de 2001 a dezembro de 2002, utilizando-se dois métodos de coleta (armadilhas de solo e o funil de Berlese - Tullgren). As espécies de histerídeos encontradas foram: Euspilostus modestus, Euspilostus (Hesperosaprinus) spp., Carcinops troglodytes e Hololepta quadridentata. O número de cada espécie diferiu entre os métodos utilizados. Na armadilha de solo, E. modestus correspondeu a 87,01% do número total de indivíduos capturados, enquanto que no funil, C. troglodytes obteve maior destaque (84,38%). E. modestus e H. quadridentata apresentaram padrões de variação mensal positivamente correlacionada com a precipitação pluviométrica (P<0,05 e P<0,01, respectivamente).

Programs for biological control are usually based on the release of predators and parasites so that no hazard is posed to the natural environment. Coleoptera of the Histeridae family feed on the larvae of synantropic diptera, enabling their use in the control of such flies. The objective of this work was to carry out a survey of the Histeridae species present at a poultry house situated in the city of São João da Boa Vista, state of São Paulo, Brazil, aiming to describe their seasonality and the possible associations between the adult specimens. Samples were collected from the poultry houses from January 2001 to December 2002, using two collection methods: soil traps and Berlese funnel. The following Histeridae species were encountered: Euspilostus modestus, Euspilostus spp., Carcinops troglodytes and Hololepta quadridentata. The number of specimens found for each species depended on the collecting method. In the case of the soil trap, E. modestus corresponded to 87.01% of the total number of collected individuals. On Berlese funnel, method C. troglodytes corresponded to 84.38% of the total number of collected beetles. The presence of E. modestus and H. quadridentata was significantly correlated to climatic variations, and positively especialy rainfall (P<0.05 and P<0.01 for E. modestus and H. quadridentata, respectively).

A study was conducted to investigate the thermal constant in an experimental population of Muscina stabulans (Fallén 1817). A natural population was obtained from a livestock and their F1 generations were maintained at four constant temperatures (16°C, 20°C, 26°C and 31°C). The thermal constant was calculated by the hyperbole method using the base temperature, tb = 4.4°C and the thermal constant K = 35.3 GD. Ricker's geometric regression, considering tb = 7.8°C and K = 28.9 GD was also calculated.

The growth of Chrysomya chloropyga (Wiedemann) larvae was compared on three different oligidic diets and mice carcass. The following performances in terms of gain in body weight were obtained: mice carcass (61.5 mg), whole dried milk plus whole dried egg (56.5 mg), whole dried milk plus casein (56 mg) and whole dried milk (55 mg). The period of most rapid growth was also different for each dietary media. This is the first time C. chloropyga has been reared on oligidic diets.

Data are given on the identification, biology, ecology, hosts, geographical distribution, control, and other aspects of the myiasis-producing flies in the Neotropical Region. The bibliography contains almost 2400 references, mainly related to Cochliomyia (ca. 1170 references), Cuterebridae (with the exception of Dematobia hominis (over 390 references), and to Dermatobia hominis (over 520 references). For Cuterebridae and Cochliomyia the bibliography covers the Américas; for ali other groups it is restricted to the Neotropics.
