摘要: 松墨天牛在我国的危险性和潜在风险性日益突出,应用辐照不育技术控制该虫是绿色防治的重要途径之一。本研究通过室内试验,测定并分析不同辐照剂量60Coγ射线辐照松墨天牛雄成虫对松墨天牛的取食、排泄、交配、产卵、寿命、防治效果等的影响,筛选对松墨天牛雄成虫的γ射线最佳辐照剂量,为该项技术的实际应用提供科学依据。结果表明,与对照相比(未进行γ射线辐照),150、200、250和300 Gy剂量(剂量率1.5 Gy/min)60Coγ射线辐照对雄性松墨天牛取食、排泄和寿命等生物学特性均无明显影响(P>0.05);4种剂量γ射线辐照的雄成虫配对后,能正常刻槽产卵,但卵的孵化率均为0,即失去生殖能力。当雌:雄:处理过雄性天牛比为1:1:6时,150 Gy剂量辐照对天牛的防治效果较好,雌雄交配后卵的孵化率仅为2.63%。权衡辐照雄成虫对其取食、排泄、交配、寿命和防治效果的整体效应,在实际应用中应选择150 Gy剂量60Coγ射线辐照为宜。

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 ofM. 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 60Coγ-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.

Key words: Monochamns alternatus, 60Coγ-ray, irradiation, control efficiency
