Abstract:

A double application of 1 % lindane failed to cure head louse infestations in 38 out of 110 children in two cities. Residue tests showed considerable resistance levels in all samples from fourteen cities. The average LD 5O's were 0.9% lindane and 2% dieldrin. A baseline for malathion was determined. LD 50 is 0.1% malathion. Some survival occurred at both 0.4% and 0.8% insecticide, contrary to observations elsewhere. The results show that field collected head lice can be used for insecticidal testing.
