60Coγ射线辐照雄成虫对松墨天牛生命力及防治效果的影响
Vitality and Control Efficiency of Monochamns alternatus Males Irradiated by 60Coγ-ray
摘要
Abstract
The Japanese pine sawyer beetle,Monochamus alternatus,is of pest status and potential risks in our country.The sterility irradiation technology is considered an environment-friendly alternative to insecticides for control of this pest.In this study,the influences of 60Coγ-ray irradiation of different dosages on feeding,excretion,mating,oviposition,longevity and reproductive capacity of M.alternatus were evaluated.And the irradiation dosage of 60Coγ-ray against M.alternatus was tested.This study provided a foundation for the practical application of this technology to control M.alternatus.The males irradiated by 60Coγ-ray of 150,200,250 and 300 Gy dosages maintained the normal levels of feeding,longevity and excretion.The mating ability of males irradiated by four dosages of 60Coy-ray with females was normal,although the mated females oviposited,no eggs hatched.When the ratio of females,normal males and irradiated males was 1∶1∶6,the 150 Gy of 60Coγ-ray showed a better control efficiency and only 2.63% of the eggs hatched.Therefore,the 150 Gy of 60Coγ-ray is recommended for practical application.关键词
