Diapause Prevention in Aphidoletes aphidimyza (Diptera: Cecidomyiidae) by Low-intensity Light

Abstract
Low-intensity radiation at night prevented diapause in larvae of the predatory midge Aphidoletes aphidimyza (Rondani) under environmental conditions (9:15 [L:D] photoperiod and 2l:l5°C [T:C] thermoperiod) that induced 100% diapause when “night” was dark. Diapause incidence was negatively related to radiation per unit area at levels 2 (50% of larvae within a 10-m radius.
