Feeding and growth of caterpillars of the Siberian moth Dendrolimus superans sibiricus (Lepidoptera, Lasiocampidae) during summer diapause
Entomological Review 82 (8), 1084-1088
Abstract: The role of the larval summer diapause in the intrapopulation synchronization of adult emergence in the Siberian moth Dendrolimus superans sibiricus Tschtvr. was assessed. The prolongation of the larval stage occurs owing to decreased consumption, assimilation, and utilization of food, in spite of the favorable conditions for development. It was shown for the example of 4th instar larvae that the summer diapause increases larval period to 3 weeks and significantly decreases the rate of food consumption in comparison with controls. In diapausing larvae, the utilization of food consumed by the larval decreases by 20% and the efficiency of use of consumed and utilized food for larval growth falls by half in comparison with controls. As a result, the relative growth rate in diapausing larvae is strongly reduced (0.009 mg/day against 0.073 mg/day in controls).
