Abstract

The present study was carried out during the season of 2013 to evaluate two insect growth regulators (IGRs) and two organophosphorous insecticides against the cotton leafworm Spodoptera litorallis (Boisd) as well as three pyrethroids against the cotton bollworms (the pink and spiny bollworms) in El-Beheira Governorate. In addition to, effect of these tested compounds on cotton yield was studied.
The results in general revealed that the IGRs had general means of infestation reduction percentages of cotton leafworm ranged between 87.4 % (Dimifron) and 85.6 % (Deflox) ,while, the organophosphorous insecticides as Nasr-Phos gave 84.7 % and Adwuprof gave 83.9%. Alfa-Power as a synthetic pyrethroid gave higher reduction of cotton bollworm with higher percentage increase of cotton yield (84.4 and 118.1 %, in respect) followed by Pest-Pox and Nasr-Thrin as follow.
