| 摘 要： | 比较研究了转Bt基因棉保铃棉、中棉30与棉常规品种防治和不防治情况下棉铃虫的发生特点。结果表明:(1)各处理间棉铃虫卵的发生时期基本一致,发生量则差异较大;(2)转Bt基因棉棉铃虫幼虫的发生量远低于常规棉(平均低72.4%);(3)在生长前期各处理均有一定数量的天敌类群,对棉铃虫的发生具有较好的控制作用。 |

| Abstract: | The characteristics of cotton bollworm(CBW) Helicoverpa armigera, in transgenic Bt cotton and general cultivars fields were comparatively studied the results were as follows: (1) All four cultivars indicated that the occurrence periods of CBW’s eggs were nearly of the same while the quantity of their eggs varies greatly. (2) The quantity of CBW’s larvae in transgenic Bt cotton was much less than that of general cultivars(- 72.4%). (3) During the former period of cotton growing a certain amount of species and its population of CBW’s natural enemies had been established which benefits the control of the incidence of the CBW. |
