Sensitivity of larvae, pupae, and adults of the driedfruit beetle (Coleoptera: Nitidulidae) to gamma radiation
Download [PDF File]
Raisins infested with three different ages of larvae of driedfruit beetle, Carpophilus hemipterus (L.), were treated with gamma radiation doses of 130-798 Gy. Pupae and unmated adults were also treated at 338 and 486 Gy. All doses to larvae prevented adult development. Only the oldest treated larvae were able to develop to the wandering stage (late third instar) before dying. Complete larval mortality occurred sooner at higher doses. Most younger larvae died within the raisins. Mortality of irradiated pupae at both doses was 90%, and adults emerging from treated pupae died within 48 h. Irradiated adults produced no progeny and died within 1 wk after treatment.
