Enhancement of The Role of Two Entomopathogenic Fungi, as a Control Measure against The Peach fruit fly, Bactrocera zonata (Saunders) (Diptera:Tephritidae) in Egypt

Abstract

Peach fruit fly, Bactrocera zonata (Saunders) is a serious and destructive pest of horticultural fruits in Egypt, tropical and subtropical regions in the world. The pest causes high loss in production annually. The frequent use of chemical insecticides to control this pest resulted many problems such as environmental pollution, pesticide residues on products and possible development of resistant and virulent strains of pest. There is a need in the whole world to develop safe and effective alternative methods for controlling this pest. Bioagents such as entomopathogenic fungi can act as the role of environmentally friend alternative to chemical insecticides. A variety of fungal enzymatic activities can be tested in sample fashion by deterging the ability of culture to grow on
