摘要
在昆虫饲养室，保持温度在２４～２６℃、相对湿度７０% ～８０%的条件，及时清除不利于寄主培育和天敌繁殖的有害生物及更换萎蔫的松苗，为实现建立湿地松粉蚧种群和湿地松粉蚧寄生蜂的寄生繁殖提供寄主条件。
An experiment was held to repreduce Oracella acuta in laboratory. While the temperature was kept between 24℃and 26℃, relativity humidity from 70% to 80%, the Ora- cella acuta population was successfully established in rearing room. Clear pest that damage to host and natural enemy, changing the wilted pine seedling in time is essentially. The test support host- ing condition to parasitic wasps of Oracella acuta.
