| A multitude of insects and mites attack fruit crops throughout the tropics. The traditional method for controlling most of these pests is the application of chemical pesticides. Growing concern on the negative environmental effects has encouraged the development of alternatives. Inundatively and inoculatively applied microbial control agents (virus, bacteria, fungi, and entomopathogenic nematodes) have been developed as alternative control methods of a wide variety of arthropods including tropical fruit pests. The majority of the research and applications in tropical fruit agroecosystems has been conducted in citrus, banana, coconut, and mango. Successful microbial control initiatives of citrus pests and mites have been reported. Microbial control of... |

| Resumo Fêmeas adultas do vespídeo Angiopolybia pallens (Lepeltier) foram observadas alimentando-se do material do ninho, ovos e girinos do ninho de espuma construído pela rã Leptodactylus pentadactylus (Laurenti) próximo de Manaus, Brasil. Larvas e adultos de moscas de efidrídeos, Gastrops willistoni Cresson, foram encontrados em todos os ninhos de espuma de L. pentadactylus encontrados entre 15 de julho a 21 de dezembro de 1978. As larvas provavelmente alimentam-se de ovos não desenvolvidos, material do ninho e dos corpos de insetos que tinham ficado presos no material viscoso. Um eucoilídeo parasito de larvas de efidrídeo foi observado "in situ" e criado em laboratório das coletas de campo de larvas de G. willistoni. Associações esporádicas adicionais... |

| The effect of the hyphomycete Paecilomyces fumosoroseus (Wise) Brown & Smith on the predatory and parasitic activity of Aphelinus asychis Walker, a common parasitoid of the Russian wheat aphid, Diuraphis noxia (Mordvilko), was investigated under three different humidities. Three cohorts of 20 female A. asychis were treated with 5.2 x 10(4) spores/cm² (twice the LD95 for D. noxia). Each female was then individually maintained in a ventilated Petri dish in which were placed three barley leaves and 20 third-instar D. noxia. Cohorts of 20 treated females were each held at one of the following relative humidities along with an equal number of untreated control insects: 67-73%, 85-89%, and 94-98%. Every 24 hours over a period of one week, the surviving... |
