【摘要】 从2001年7月10日至2001年8月29日,在山西省应县林场一片10公顷杨树林中,通过释放85Gy辐射不育光肩星天牛雄虫,对辐射不育法控制光肩星天牛种群繁殖的效果进行了研究。尽管平均释放比仅为2～5,但不同方法的调查结果都显示,释放的辐射不育虫有效地抑制了林间光肩星天牛自然种群的繁殖。结果表明,当代光肩星天牛种群卵孵化率为20%左右,F1代存活率为27%左右。更多还原

【Abstract】 An experiment to evaluate the effect of released sterile insects on reproduction of natural A. glabripennis population was conducted at a 30-hectare poplar tree forest in Ying County of Shanxi Province from July 10 to August 29, 2001. Though the releasing ratio was only about 2～5, results from different methods showed that the reproduction of natural A. glabripennis population was suppressed effectively by releasing sterile insects, and that hatch ratio of eggs laid by parent generation was about 20% and survival ratio of F1 progeny about 27%.更多还原
