In laboratory trials with the pathogenBacillus thuringiensis H-14 (B. t. H-14) against culicine larvae ofCulex pipiens L. andAedes aegypti (L.), the following factors significantly influenced larvicidal activity: larval instars, mosquito species, exposure time and temperature. Variation in water pH, however, did not significantly affected efficacy. Different levels of potentiation and additive effects were also obtained when the bacterial agentB. t. H-14 applied jointly with the chemical… CONTINUE READING
