| Abstract |
The effectiveness of two compounds diflubenzuron (Dimilin) and chlorfluazuron (Atabron 5% EC) belonging to insect growth regulators (IGR) groups, against newly hatched larvae of pink bollworm (PBW), Pectinophora gossypiella (Saund.) was tested under laboratory condition of 27° t 1° C and 7580% R. H. LCSO was determined (0.0423) for Dimilin and (0.1961) for Atabron. Also, the effect of the two (IGR) compounds on some biological aspects of PBW was studied.
Insect growth.regulators prolonged the larval duration by 21.62& 23.76 for Dimilin & Atabron, respectively, than control. Also, increased the pupat period and duration of immature stages.
Two IGR caused shortened the oviposition period, where, this period estimated by 12.06 and 10.8 days for Dimilin & Atabron, than control. Also, effect on some other biological characters, such as total deposited eggs / female, hatchability, fecundity and longevity of emerged female. Results indicated that the two tested IGR compound (Dimilin & Atabron) increased pre-oviposition period, but caused shortness of female oviposition period and adult longevity. Also, they decreased the average number of deposited eggs /female.
Also some biochemical studies were carried out on larvae treated by LC50 Dimilin & Atabron to determination activities of enzymes GOT & GPT, carbohydrate hydrolyzing enzymes and total nutrient content, i.e. proteins, lipids and carbohydrates. Data revealed that treated larvae of PBW by Dimilin & Atabron caused increased total lipids, transaminase enzymes GOT & GPT, carbohydrate hydrolyzing enzymes (Invertase & Trehalase). While, cause decreased in total soluble proteins and the activity of carbohydrate hydrolyzing enzymes Amylase.
