Survival of Helicoverpa punctigera (Wallengren) and H. armigera (Hübner) (Lepidoptera: Noctuidae) pupae submerged in water
Journal of the Australian Entomological Society 29 (3), 191-192
Abstract: The effect of varying periods of submersion in water on survival of non-diapausing pupae of Helicoverpa punctigera (Wallengren) and H. armigera (Hübner) was investigated. At 25°C the submersion time to kill 50% of pupae was 49 h for H. punctigera and 35 h for H. armigera. Since pupae survive relatively long periods under water, drowning may not be an important mortality factor in the field except when prolonged waterlogging occurs.
