Effect of Gamma Irradiation and/or Entomopathogenic Fungi on Some Biological Aspects of Galleria mellonella L. (Lepidoptera: Pyralidae)

Abstract

Studying the impact of gamma radiation in conjunction with the LC50 of the entomopathogenic fungi on a few biological characteristics of Galleria mellonella (L.) larvae was the goal of the current work. The effects of single doses of gamma radiation (70, 100, 125, and 150 Gy) given sequentially or combined with the LC50 of specific entomopathogenic fungi (Beauveria bassiana, Paecilomyces lilacinus) against the Greater wax moth. The first generation (F1) of G. mellonella was examined for its larval pupal period, pupation percent, sex ratio, and adult survival percent. Gamma irradiation and LC50 of combined treatments of Beauveria bassiana and Paecilomyces lilacinus prolonged the larval-pupal period, while pupation, adult emergence, survival and sex ratio were lower in the combined treatment than in either treatment alone get more. The combined treatment was greater than either, in the case of fungal or irradiation treatment alone.
