| Factors such as fertilization, allelochemicals, trichomes, weather, and natural enemies can influence pest populations. Thus, it is necessary to understand the factors that predispose vegetable species to pests and the role of polyculture, crop rotation, and neighboring plants. The objective of this research was to study the hosting capacity for pests of Abelmoschus esculentus (L.), Brassica oleracea L. vars. acephala and capitata, Capsicum annuum L., Cucurbita moschata (Duchesne), Cucurbita maxima Duchesne and Cucumis sativus L., Lycopersicon esculentum Mill., Solanum gilo Raddi and Solanum melongena L., and Phaseolus vulgaris L. The higher density of Bemisia tabaci (Genn.) adults on C. sativus can be due to the higher amount of pentacosane and octacosane... |

| ABSTRACT Thysanoptera species can transmit virus to Solanaceae family vegetables, including tomato plants for industrial processing, causing the disease known as Tomato Spotted Wilt Virus (TSWV). Thrips resistance to insecticides indicate the urgent need of techniques adequate for Integrate Pest Management practices. The objective was to evaluate the control efficiency (CE%) against Frankliniella schultzei (Thysanoptera: Thripidae) of the fungus Beauveria bassiana (Bb), the resistance inducer potassium silicate (KSil) and the chemical insecticide profenophos + cypermethrin (PC) isolated, or in binary mixtures. The treatments were foliar spraying on tomato plants with Bb (T1), KSil (T2) and PC (T3) isolated or in mixtures of Bb+KSil (T4), PC+KSil (T5) and... |

| This is the first record of immature stages of species belonging to the subgenus Nyssorhynchus (Blanchard) in eutrophized breeding habitats. Larvae of Anopheles (Nys.) evansae (Brethes), Anopheles (Nyssorhynchus) rangeli (Gabaldon et al), Culex nigripalpus (Theobald) and Culex quinquefasciatus (Say) (Diptera: Culicidae) were collected in a rural eutrophized dam in Rio de Janeiro State, in Southeastern Brazil. Eutrophication was substantiated by the low diversity of mosquitoes, the high incidence of Cx. quinquefasciatus (42%) and of Daphinia sp. and, the high levels of both organic nitrogen (0.28 mg/l) and total phosphorus (0.02 mg/l). |

| Palmistichus elaeisis Delvare & LaSalle é um parasitóide pupal natural de pupas de lepidópteros desfolhadores de eucalipto e é considerado um promissor agente de controle biológico. No entanto, o desenvolvimento de técnicas de criação eficientes desse inimigo natural é inicialmente necessário para que ele possa ser utilizado em programas de controle biológico. Pupas de Bombyx mori L. são hospedeiras alternativas em potencial para criação massal de P. elaeisis. Por isto, nós avaliamos a idade mais suscetível do hospedeiro e os efeitos da idade do parasitóide na produção de progênie de P. elaeisis. Pupas de B. mori com 24, 48, 72 ou 96h de idade foram expostas a fêmeas de P. elaeisis de mesmas idades. A duração do ciclo de vida (ovo-adulto) de P.... |

| Nymphs of Podisus nigrispinus (Dallas, 1851) were fed with Zophobas confusa Gebien, 1906, Tenebrio molitor Linnaeus, 1758 (Coleoptera, Tenebrionidae) and Musca domestica Linnaeus, 1758 (Diptera, Muscidae) under 25±0.5ºC, 60±10% of RH and photophase of 12h. Nymphal viability of P. nigrispinus were 64.0%, 80.0% and 92.0% with Z. confusa, M. domestica and T. molitor, respectively. No differences were found for pre-oviposition period, number of egg masses, number of eggs, egg viability, and longevity for females of this predator fed with any of these preys. |
