25. INTERACTION BETWEEN THE COTTON BOLLGARDTM, THE TWOSPOTED SPIDER MITE, Tetranychus urticae KOCH (ACARI: TETRANYCHIDAE) AND ITS PREDATORY MITE Phytoseiulus macropilis (BANKS) (ACARI: PHYTOSEIIDAE). / INTERAÇÃO ENTRE O ALGODOEIRO BOLLGARDTM, O ÁCARO RAJADO, Tetranychus urticae KOCH (ACARI: TETRANYCHIDAE) E O PREDADOR Phytoseiulus macropilis (BANKS) (ACARI: PHYTOSEIIDAE)
Cotton plants have been genetically transoformed with genes from the bacterium Bacillus thuringiensis Berliner (Bt) which confers the plant resistance against certain lepidopoteran pest species. The Bt-cotton carries genes that express the toxin Cry1Ac. This creates new interactions in the agroecossystems encouraging researches to answer the questions about

26. Nutrition of the tomato and her influence in the preference for shelter, feeding and oviposition of Bemisia tabaci (Genn.) biotype B / Nutrição do tomateiro e a sua influência na preferência para abrigo, alimentação e oviposição de Bemisia tabaci (GENN.) biótipo B
A Bemisia tabaci biótipo B constitui-se atualmente uma grande ameaça não só a cultura do tomateiro mais a diversas outras culturas. O objetivo dessa pesquisa foi avaliar a influência da nutrição do tomateiro na indução de resistência para abrigo, alimentação e oviposição de B. tabaci biótipo B. Os experimentos foram conduzidos na Escola de Agr

27. Laboratory and field evaluation of an oviposition trap for Culex quinquefasciatus(Diptera: Culicidae)
An ovitrap (BR-OVT) based on physical and chemical stimuli for attracting gravid Culex quinquefasciatus (Diptera: Culicidae) females was developed and evaluated under laboratory and field conditions. Attractants were assayed using alternative chamber bioassays prior to being used in the BR-OVT oviposition trap. A significant preference of gravid females for

28. Biological aspects and preference for oviposition by Bemisia tabaci (Gennadius, 1889) biotype B (Hemiptera: Aleyrodidae) on cotton cultivars / Aspectos biolÃgicos e preferÃncia para oviposiÃÃo por Bemisia tabaci (Gennadius, 1889) biÃtipo B (Hemiptera: Aleyrodidae) em cultivares de algodoeiro
The purpose of this work was to evaluate some biological aspects of egg and nymphal stages of Bemisia tabaci (Gennadius, 1889) biotype B (Hemiptera: Aleyrodidae) and to study its preference for oviposition and the effect of the presence, number and type of trichomes on the cotton cultivars BRS IpÃ, BRS 186-Precoce 3, BRS Acala, BRS Verde, BRS-200 Marrom, BR

29. Silicon influence on resistance induction to the whitefly Bemisia tabaci biotype B (Genn.) (Hemiptera: Aleyrodidae) and on vegetative development in two soybean Glycine max (L.) Merrill cultivars. / InfluÃncia do silÃcio na induÃÃo de resistÃncia à mosca-branca Bemisia tabaci biÃtipo B (Genn.) (Hemiptera:Aleyrodidae) e no desenvolvimento vegetativo em dois cultivares de soja Glycine max (I.) Merrill.
The potential for resistant Bemisia tabaci populations to develop as a consequence of intensive use of chemical insecticides has stimulated studies on integrated pest management tactics, for example, the induction of host-plant resistance. Recent studies have shown that silicon can increase plant resistance against insects. The objectives of this work were t

30. Moscas dos generos Hippelates Loew, 1863 e Liohippelates Duda, 1929 (Diptera: Chloropidae) : levantamento, sazonalidade e parametros biologicos
Liohippelates peruanus (Becker) (Diptera: Chloropidae) is one of the most abundant species in the city of Campinas, São Paulo state and it has been described as mechanical vector of the bacteria Haemophilus aegyptius, the agent of conjunctivitis and of the Brazilian Purpuric Fever (Paganelli &Sabrosky 1993), it occurs in larger number in the hottest periods

31. Aceitação e preferência de frutos para oviposição em duas populações de Ceratitis capitata (Diptera, Tephritidae)
The influence of four host fruits, orange (Citrus sinensis L.), papaya (Carica papaya L.), mango (Mangifera indica L.) and apple (Malus domestica Borkh) on oviposition behavior of Ceratitis capitata (Wiedemann, 1824) was evaluated. Experiments were carried out on two C. capitata laboratory-reared populations: one with artificial diet for 10 years with period

32. The role of urea in the oviposition behaviour of Japanese encephalitis vectors in rice fields of South India
The effect of urea on the oviposition behaviour of culicine vectors of Japanese encephalitis was studied in rice fields. Gravid females had a strong preference for oviposition in urea treated areas in rice fields, while no such preference was exhibited in untreated areas. The egg laying declined in the area where urea treated water surface had a mechanical b

33. Population dynamics, gregarious behavior and oviposition preference of Neomegalotomus parvus (Westwood) (Hemiptera: Heteroptera: Alydidae)
Interações entre Neomegalotomus parvus (Westwood) e plantas hospedeiras foram estudadas em relação ao monitoramento da população durante o ano, comportamento gregário no campo e preferência para oviposição entre plantas hospedeira e não hospedeiras em gaiolas no campo. Feijão-de-corda, Vigna unguiculata (L.) Walp., soja, Glycine max (L.) Merr. cv

34. Oviposition behavior and performance aspects of Ascia monuste (Godart, 1919) (Lepidoptera, Pieridae) on kale (Brassica oleracea var. acephala)
Host part selection by ovipositing females of Ascia monuste (Godart, 1919) (Lepidoptera, Pieridae) on kale (Brassica oleracea var. acephala) was determined in greenhouse and field. Performance of offspring (larval period, efficiency of food utilization, number of eggs/female and others) was investigated under laboratory conditions. In the field, the number o

35. Preferência por local de oviposição de Aedes albopictus (Skuse) (Diptera, Culicidae), em relação à presença de imaturos da própria espécie, sob condições de laboratório
Aedes (Stegomyia) albopictus (Skuse, 1894) is an exotic Culicidae species in Brazil. Since its first report in this country, the mosquito has been increasing its geographic distribution. This mosquito is a natural dengue and Japanese Encephalitis virus vector in Asia. The females preference for oviposition sites related with homospecific immature presence wa

36. Variation of the Oviposition Preferences of Aedes aegypti in Function of Substratum and Humidity
Two Aedes aegypti (L.) populations were studied in the laboratory regarding the preference for three types of breeding sites, i.e., flasks containing only water, flasks with a plant and flasks with a stick. Each of these breeding units was placed in one cage and the choice of the oviposition sites was determined for individual females and three females per e
