Abstract
A study was carried out on the potential impact of certain insecticides on the
abundance of the pink bollworm, Pectinop < /em>hora gossyp < /em>iel/a (Saunders) on cotton in
Kafr El-Sheikh Governorate, Egypt, during 2002 and 2003 seasons. Results showed
that fenpropathrin and thiodicarb were the most effective toxicants, whereas,
profenofos occupied the last class in reducing the pink bollworm population.
Deltamethrin and chloropyrifos were of moderate effect in this respect. Also, the
changes in susceptibility of the larvae to insecticides were studied using the residual
vial bioassay technique. Data showed that the pink bollworm larvae were more
tolerant to the tested pyrethroids than the carbamates and organophosphates
insecticides. The study indicates the potentiality of the vial bioassay technique to give
data that may serve as reference values to determine if tolerance to any of the
insecticides develops in field populations of the pink bollworm.
