Augmentation of Trichogrammatoidea Bactrae Nagaraja in the IPM Programme for Control of Pink Bollworm, Pectinophora Gossypiella (Saund.) In Egypt

Alia Abd El-Hafez and M. A. Nada


 
ABSTRACT

Studies were carried out to estimate fundamental bases needed for handling Trichogrammatoidea bactrae Nagaraja against pink bollworm, Pectinophora gossypiella (Saund.) eggs under field conditions; i.e., the device of release, the suitable distances between T. bactrae release points and the effect of some climatic factors (temperature and % relative humidity) on the emergence of the parasitoid from parasitized eggs and it's capability to parasitize new pink bollworm eggs. Also, studies were conducted to determine the role of augmenting T. bactrae in the IPM program for controlling pink bollworm. Field experiments were conducted during three successive cotton seasons from 1995 to 1997 under recommended cotton pests control program practices at El-Ebrahemea region, Sharkia Governorate cultivated with Giza 85 cotton variety.
