果核杧果象生物学特性研究

截获泰国产芒果中的果核杧果象,在我国气候环境下对该虫的幼虫和蛹饲养、成虫越冬存活率及浸水死亡率等进行研究.该虫在原芒果果核内饲养的幼虫出成虫存活率为59.1%,蛹为75%;在恒温湿条件下保湿饲养的幼虫出成虫存活率为27.3%,蛹为36.3%.成虫恒温湿条件下不同材料中越冬存活率均达66%以上,常温湿条件下平均不足49%.越冬前成虫浸水10h全部死亡,常温湿条件下越冬后成虫浸水6h全部死亡,恒温恒湿条件下越冬后成虫浸水8h全部死亡.研究结果表明,泰国产的果核杧果象在我国南方环境条件中化蛹、羽化、越冬仍然存在较高的存活率,该虫可以在我国南方芒果产区定殖危害.

The research of Sternochetus olivieri (Faust) (Thailand) in biological characters

This paper studies the larvae and pupae feeding, the adults overwintering livability, and soaking in water death rate of Sternochetus olivieri (Faust), finding in the mango from Thailand, under the our country weather environment. The larvae feeding in the mango seed become the adults livability as 59.1%, the pupae are 75%; The larvae feeding under the constant temperature and wet condition become the adults livability as 27.3%, the pupae are 36.3%; The adults livability overwintering under the constant temperature and wet condition reach to 66% above, the normal temperature and wet condition are average not enough 49%. Soaking in water, all the adults before overwintering die in 10 hours, the adults overwintering under the normal temperature and wet condition are 6 hours, the adults overwintering under the constant temperature and wet condition are 8 hours. The results showed that the Sternochetus olivieri (Faust) from Thailand, turning to pupae and adults, overwintering in the our country the southern environment condition, still exists a higher livability. That insect can exist and harm at the southern mango produce area of our country.
