In malaria endemic villages of the Indian State of Orissa, the impact of be
dnets treated with lambdacyhalothrin at 25 mg/m(2) on malaria vectors was a
ssessed during a 3-year intervention trial beginning in May 1990. The main
malaria vector was Anopheles culicifacies with a small contribution from An
opheles fluviatilis. The impregnated bednets caused a significant reduction
in vector density as assessed by morning indoor resting catches, man-bitin
g rate, light trapping, the proportion of females engorged with human blood
, and the parity rate as compared with villages with untreated or no nets.
No statistically significant difference was observed in these parameters be
tween the villages with untreated nets or no nets. The trial demonstrated t
hat the lambdacyhalothrin-treated nets were highly effective against the ma
laria vectors.
