Abstract
The present work was conducted in Qalubyia Governorate during 2010 to control the potato tuber moth, Phthorimaea operculella (Zeller) (Lepidoptera: Gelichiidae) in rustic farm storage and potato fields. Results showed that, double release of the parasitoid, Trichogramma evanescens Westwood and the predators, Chrysoperla carnea (Stephens) and Orius albidipennis (Reuter) were effective as biological agents against P. operculella under straw-cover heaps. The highest reduction percentage occurred with application of both T. evanescens and C. carnea, they reduced the infestation to 75.56% whereas application of both T. evanescens and O. albidipennis reduced the infestation to 56%. Application of O. albidipennis alone gave poor reduction percentage (5.1%). One release of O. albidipennis reduced the infestation to 21% in the field. However, application the agronomic cultural practices reduced rate of infestation to 45% at the trail end in the storge.
