| 摘 要： | ３００ Ｇｙ γ射线辐照棉铃虫（ Ｈｅｌｉｃｏｖｅｒｐａ ａｒ ｍ ｉｇｅｒａ Ｈｕｂｎｅｒ） 成虫（ 棉田第１ 代） 在田间的扩散试验表明：释放的标记虫约９７ ％ 集中在离释放点半径７２０ ｍ 的范围内。最远平均扩散距离为６１５ ｍ 。棉铃虫扩散密度与扩散距离呈倒数相关，符合模型 Ｎ ＝－ ０８３ ＋ １６４７３４／ ｘ 。野生棉铃虫有向嫩绿寄主植物扩散的趋势。

| Abstract: | The field dispersal ability of cotton bollworm, Helicoverpa armigera(Hübner) irradiated with 300Gy of γ rays was studied. The results showed that about 97% of cotton bollworm was dispersed in 720m. The 615m was the farthest of average dispersal distance. The dispersal density of cotton bollworm was correlated with the reciprocal of dispersal distance, as the model: N=-0 83+1647 34/x. The dispersal of cotton bollworm had taxis to the green and fresh host. |
