Abstract | Persistence of Bacillus thuringiensis var. israelensis (Vectobac WDG) and methoprene (Metoprag S-2G) was evaluated against
Aedes aegypti late third instar larvae of the Rockefeller strain in a semi-field bioassay. Tests were performed in Rio de Janeiro,
using containers made of plastic, iron, concrete and asbestos, placed in a shaded area. The formulations used were 0.2 g of
Vectobac-WDG and 1g of Metoprag S-2G per 100 liters of water in house storage containers. Vectobac WDG was tested twice, in
March and in April/May, 2002. In March (temperature ranging from 21.5 to 39.3 ºC), 70-100% mortality was observed by the 7th
day and declined abruptly thereafter. No significant differences were observed among the container types. In April/May (18.6 to
34.8 ºC) mortality was higher than 70% to 30-36 days in all cases, except in the iron container (40% mortality on the 12th day).
Metoprag S-2G was evaluated in April/May, 2002, and induced mortality higher than 70% up to 15 days in the plastic and iron
containers and only seven days in the concrete container. In the asbestos container, maximal mortality was achieved on day one
post-treatment (66%). Our results point to a low persistence of both formulations in the weather conditions of Rio de Janeiro. | pt_BR |
