Effect of gamma irradiation and/or certain entomopathogenic fungi on the larval Mortality of Galleria mellonella L

Article scientifique 2018 Anglais

Résumé

The present investigation was carried out to study the effect of LC 50 of the entomopathogenic fungi (EPF), Paecilomyces lilacinus and Beauveria bassiana , on larval mortality of the greater wax moth (GWM), Galleria mellonella L., under laboratory conditions and also to study the effect of different doses of gamma irradiation (70, 100, 125, and 150 Gy), separately or combined with the LC 50 of the isolates of the EPF, B. bassiana , and P . lilacinus , on the second-instar larvae of G. mellonella larval mortality. The combined treatment of gamma irradiation and EPF increased the larval mortality rates than that at each treatment alone. The highest percentage of larval mortality was 78 and 84%, with 125 Gy + B. bassiana in the case of F 1 male and F 1 female, respectively. According to the obtained results, the gamma irradiation increased the pathogenicity of the fungi against the tested larvae. The combination between the two control tools may provide satisfactory control of the insect-pest, especially, in the storage.
