Abstract:
Schizotetranychus bambusae Reck is an important pest injuring the leaves of bamboo. The mite hibernates on fallen leaves.In the soil chink of the basis of bamboo and in the leaf sheaths as impregnated female adults.They move out in the first decade of April the next year and hibernate slowly in October.The period of each dcvdopmental stage is negatively correlated with temperature Ianged from 20℃to 30℃.The developmental peri-od of one generation is 20 days at 20℃, and 10.3 days at 30℃.The period of oviposition is the longest(17.8 days)at 20℃.Average egg number per female is the largest (28.0)at 25℃.The peak of oviposition is on 4-8 days after hatching.The effective accumulated temperature of one generation is 204.7 day—degree and the developmental zero is 9.6℃.
Key words: Schizotetranychus bambusae Reck, Bionomics, Effective. accumulated temperature, Generations
