| Abstract |
The pink bollworm, Pectinophora gossypiella (Saunders) is a serious pest of cotton in many parts of the world. Abbas et a1. (1996), Al-Shannaf (2002) and Aioub et al. (2003) reported that the developmental stages of bollworms are greatly influenced with insecticidal and IGRs treatments.
The pteromalid wasp Dibrachys cavus (Walker) was recorded as a generalist gregarious ectoparasitoid on the diapausing larvae of P. gossypiella existing in cotton bolls in different countries (Chu, 1978 and Cock, 1985) and attacking many species of Lepidoptera (Zerova et al., 1986 and Tkachev 1976).
Profenofos, (Curacron 72% EC) has been tested against many lepidopterous such as, P. gossypiella, Earias insularra and Spodoptera littora/is (Abbassy et al., 1984; Saad et al., 1984; Kassem et al., 1986 and Temerak 2003).
Also, IGR's were studied against P. gossypiella E. insulana and other pests by many authors as Simwat and Dhawan (1992), Rashad et al. (1993), Horowitz et a1. (1992) and Perveen (2000). On the other hand, some others studied the effect of many insecticides and IGR compounds on some natural enemies such as Bracon, Microplitis and Caroliechiles nigriceps (Tillman and Mulrooney, 2000; Stapel et al., 2000 and Khafagi and Hegazi, 2000).
The best way to conserve beneficial insects is to spray pesticides only when necessary. For this reason the present study aimed to investigate the relative efficiency of profenofos and diflubenzuron on the pink bollworm and following the effect on its parasitoid D. cavus when fed and rearing on treated host larvae.
