Cold-hardiness in the predatory miteAmblyseius potentillae (Acari: Phytoseiidae)
Tóm tắt
Cold-hardiness was studied in the predatory miteAmblyseius potentillae (Garman) by determining the mortality after exposure to −5°C. Predators reared under diapause-inducing conditions were more cold-resistant than mites that had been kept under long-day conditions. An acclimatization period at 4°C prior to exposure to sub-zero temperatures had a positive effect on the cold-hardiness of the predator, and was remarkable in diapausing mites. Lower temperatures during diapause induction had a positive effect on cold resistance in this predator; mites in which diapause was induced at 15°C were more cold-resistant than mites that had been subjected to short-day conditions at 18 and 20°C. A day/night temperature rhythm did not increase the cold-hardiness of the mite when grown under long-day conditions. Such a rhythm did increase the cold-hardiness of the diapausing predator when given a short acclimatization period, but this effect disappeared after longer acclimatization periods.
