Atividade inseticida de extratos aquosos de meliáceas sobre a mosca-branca Bemisia tabaci (Genn.) biótipo B (Hemiptera: Aleyrodidae)
[Insecticidal activity of aqueous extracts of meliaceae plants on the silverleaf whitefly, Bemisia tabaci (Genn.) biotype B (Hemiptera: Aleyrodidae)]
Neotropical Entomology 30 (1), 133-137
Abstract: The insecticidal effect of aqueous extract of twigs, leaves, fresh fruits and ripe fruits of Melia azedarach L. and twigs, leaves and cortex of Trichilia pallida Swartz was evaluated on eggs and nymphs of silverleaf whitefly Bemisia tabaci (Genn.) biotype B reared on tomato plants. The extracts were tested at the concentration of 3% (w/v). In the first experiment, the extracts were applied only on the egg stage. In the second experiment, the extracts were applied on eggs and 3-day old nymphs. Independent experiments were carried out for each plant species. The parameters evaluated were mortality and duration of egg and nymphal stages. Concerning M. azedarach, fresh fruits were the most effective plant structure followed by leaves and ripe fruits. For T. pallida, twigs were the most effective structure followed by leaves. The extract of twigs of M. azedarach and cortex of T. pallida did not show significant insecticidal activity. None of the plant extracts affected the duration of the immature stages.
Avaliou-se a atividade inseticida de extratos aquosos (na concentração de 3% p/v) de ramos, folhas, frutos verdes e frutos maduros de Melia azedarach L. e de ramos, folhas e córtex de Trichilia pallida Swartz, ambas Meliaceae, sobre ovos e ninfas da mosca-branca Bemisia tabaci (Genn.) biótipo B, criada em tomateiro. No primeiro experimento, os extratos foram aplicados sobre ovos, enquanto no segundo, a aplicação foi feita sobre ovos e ninfas com três dias de idade. Foram conduzidos experimentos independentes para cada espécie vegetal. Os parâmetros avaliados foram mortalidade e duração das fases de ovo e ninfa. Os frutos verdes de M. azedarach foram a estrutura vegetal mais efetiva, seguindo-se as folhas e os frutos maduros. Para T. pallida, os ramos foram os mais efetivos, vindo a seguir as folhas. Os extratos de ramos de M. azedarach e de córtex de T. pallida não apresentaram efeito inseticida significativo. Nenhum dos extratos testados afetou a duração das fases imaturas.
