Resumen:
Abstract Larvicidal effects of interaction betweenLarvicidal effects of interaction between
Bacillus thuringiensis var. israelensis (Bti), temephos
and Leptolegnia chapmanii zoospores on larvae ofvar. israelensis (Bti), temephos
and Leptolegnia chapmanii zoospores on larvae ofLeptolegnia chapmanii zoospores on larvae of
Aedes aegypti were determined under laboratory and
seminatural conditions. In laboratory bioassays, two
concentrations of Bti (0.012, 0.027 ppm), two of
temephos (0.00035, 0.001 ppm), and a single concentration
of L. chapmanii zoospores (6.1 9 104 zoospores
ml-1) were evaluated. Trials under field-like
conditions were performed in a single container and
then placed either in the shade or in direct exposure to
sunlight. We evaluated concentrations of Bti and
temephos at 3-fold those normally used in laboratory
tests: 0.09 and 0.003 ppm, respectively, plus
1.8 9 105 zoospores ml-1 of L. chapmanii. The
combined effect of sublethal concentrations of Bti,
temephos, and L. chapmanii zoospores thus indicated
that this fungus is not inhibited by the larvicides and
