Ragb. Consoli et al., SOME ENVIRONMENTAL AND BIOLOGICAL FACTORS INFLUENCING THE ACTIVITY OFENTOMOPATHOGENIC BACILLUS ON MOSQUITO LARVAE IN BRAZIL, Memorias do Instituto Oswaldo Cruz, 90(1), 1995, pp. 121-124
The influence of environmental and biological factors on the efficacy
of Bacillus thuringiensis serovar israelensis and B. sphaericus as mos
quito larvicides are reviewed. The importance of strain dependence, cu
ltivating media/methods, mosquito species/specificity, formulations an
d their relation to mosquito feeding habits, as well as temperature, s
olar exposure, larval density and concomitant presence of other aquati
c organisms are addressed with reference to the present status of know
ledge in Brazil.
