49. Ocorrência de Toxorhynchites (Diptera, Culicidae) em Mata Atlântica, Viçosa, MG, e predação de T. violaceus sobre larvas de Aedes aegypti / Occurrence of Toxorhynchites (Diptera: Culicidae) in the Atlantic Forest at Viçosa, MG, and predation of T. vilolaceus on Aedes aegypti larvae
Toxorhynchites are long legs Culicidae. Their larvae are aquatic predators that feed on invertebrate immatures, mainly mosquito larvae, in natural or artificial water reservoirs or ponds, where larvae of mosquito disease vectors develop. Toxorhynchites adults feed exclusively on carbohydrates, what make them incapables of transmitting pathogens to human bein

50. Efeitos de inibidores de proteinases de soja em organismos não-alvo associados à cultura da cana-de-açúcar / Effects of soybean proteases inhibitors on non-target organisms associated to sugarcane
Genes of plants expressing insect proteinase inhibitors have been introduced into plants for pest control. Proteases inhibitors are present in plant tissues, mainly in seeds, and act in response to predators and pathogens. The Bowman-Birk type and Kunitz type of serine proteases inhibitors (PI) from soybean seeds are been used to increase resistance of sugar

This paper describes for the first time immature stages of Cynea diluta (Herrich-Schaffer). The specimens have been collected in plants of Alpinia purpurata (Zingiberaceae) locale knew as Panamá that grow naturally in the campus Dois Irmãos of the Federal Rural University of Pernambuco (UFRPE) and in private properties in Recife, Pernambuco. The external m

53. Seletividade de inseticidas reguladores de crescimento e de neonicotinÃides a Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) / Selectivity of insecticides growth regulators and neonicotinoids insecticides to Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae)
The effects of acetamiprid (0.05 g a.i./L), lufenuron (0.04 g a.i./L), imidacloprid (0.14 g a.i./L), novaluron (0.02 g a.i./L), triflumuron (0.14 g a.i./L) and pyriproxifen (0.1 g a.i./L) on the immature and adult stages of Trichogramma pretiosum Riley were evaluated. The work was divided in two bioassays. In the first one, eggs of Anagasta kuehniella (Zelle

54. Fogo, fenologia foliar e a fauna de lagartas em Byrsonima coccolobifolia kunth (malpighiaceae)
Despite the abundance of lepidopteran species, there are few studies focusing on lepidopteran caterpillars, such as their biology, the interactions with their host plants and the effects of fire on their community structure in Cerrado. The aim of the present study was to evaluate the effects of fire on foliar phenology of Byrsonima coccolobifolia Kunth (Malp

55. Morfologia dos ovos, dos estágios imaturos, do intestino médio e das glândulas salivares de Podisus distinctus (Heteroptera: Pentatomidae) / Egg morphology, immature stages, midgut and salivary glands of Podisus distinctus (Heteroptera: Pentatomidae)
The subfamily Asopinae presents a large number of predatory species, including Podisus distinctus (Stal) (Heteroptera: Pentatomidae) as one of the main species of this genus. These insects can be reared in laboratory and it presents potential for biological control of Lepidoptera defoliators in Brazilian eucalyptus plantations. This study aimed to describe t

56. Stomoxys calcitrans: Estabelecimento de colônia e efeito de Metarhizium anisopliae sobre seus estágios imaturos / Stomoxys calcitrans: colony establishment and effect of Metarhizium anisopliae in their immatures stages
Stomoxys calcitrans is a hematophagous fly that is related to reduction in animal production due to the stress and dissemination of pathogens. The knowledge in plague control, using entomopathogenic fungi, has been growing year by year, but few works have been done to control S. calcitrans. The aims of this study were rearing a colony of S. calcitrans to mak

57. Preliminary data on the performance of Aedes aegypti and Aedes albopictus immatures developing in water-filled tires in Rio de Janeiro
A monthly survey of Aedes aegypti and Aedes albopictus immatures in discarded tires at a site in metropolitan Rio de Janeiro showed that Ae. albopictus was much more abundant in the rainy season, but Ae. aegypti abundance showed a less clear seasonal pattern. Pupal masses for Ae. albopictus showed a seasonal trend. In contrast, Ae. aegypti pupae did not show

58. Artropodes associados as carcaças de pequenos roedores expostas em area de formação vegetal secundaria no municipio de Campinas, SP / Arthropods associated with small rodent carcasses exposed in a secondary wood area in the municipality of Campinas, SP
Although studies of the post-mortem fate of human corpses are of forensic interest, and in natural environments large animals become available to insect colonization soon after death, the fate of the vast number of small carcasses in some habitats, as well as the parameters that lead this process, are not objective of important investigations. Due to this si

59. Desenvolvimento e reprodução do predador Brontocoris tabidus (Heteroptera: Pentatomidae) no campo após exposição à deltametrina / Development and reproduction of the predator Brontocoris tabidus (Heteroptera: Pentatomidae) in field conditions after exposition to deltamethrin
Insecticide usage can have a detrimental impact on the development and reproduction of natural enemys populations. Pyrethroids such as deltamethrin is widely used in agroecossystems and forest plantations where has shown selectivity to beneficial insects such as predatory bugs. The soldier bug Brontocoris tabidus (Signoret, 1852) (Heteroptera: Pentatomidae)
