Abstract: 
Bioassays against larvae of A. aegypti were conducted with neem seed kernel extracts obtained by extraction with water and organic solvents. Permanent exposure of 4th instar larvae to treated water resulted in a conspicuous growth-disrupting effect, mainly during imaginal development [insect growth regulators (IGR)]. The effectiveness of the extracts increased with decreasing polarity of the solvents used for extraction. Three neem seed kernel extracts caused an extreme prolongation of the larval period when 1st instar larvae were continuously exposed to treated water until adult emergence. The time necessary for lethal action of neem seed kernel extracts to set in was similar to that reported for some synthetic IGR.
