THE EFFECTOF ULTRAVIOLET RADIATION AND SOME INSECT GROWTH REGULATORS(IGR) ON EGGS OF GREATER WAX MOTH .GALLERIA MELLONELLA (LEPIDOPTERA : PYRALIDAE)

Abstract

The study was conducted for 1/11/2016 and so 15/5/2017 the greater wax moth Galleria mellonella (Lepidoptera: pyralide) was reared in the lab to determine the effect of ultraviolet radiation at different exposure times, different distances, and insects growth regulators Match and Neporax, and their synergetic effects on eggs mortality percentages . TheResults showed that one-day eggs treated with ultraviolet radiation from a distance of 5 or 10 cm or when treated with growth regulators were more mortality than that of six days eggs , positive proportion was found between The eggs mortality percentages and duration of exposure to radiation or concentration of growth regulators, growth regulator Neporax at 2 ml / L was more affected to the eggs mortality percentages than the growth regulator Match at the concentration of 2 g / L which cause mortality percentages (77 and 48)% Respectively , the synergetic effect between the ultraviolet radiation of 10 cm and the time of 5 minutes with growth regulators Match and Neporex at concentration of 0.5 ml or g / l or vice versa, one day eggs have mortality percentages more than six days eggs , highest eggs mortality percentage 88% were recorded at synergetic between UV and the growth regulator Neporex. The results of this study indicate the possibility of using alternative methods instead of chemical pesticides for control the greater wax moth.
