Trichogramma showed high control efficacy on cotton bollworm eggs after three times of release both in the second and in the third generation bollworm periods. The parasitism on the second and third generation bollworm eggs were 66.0%-70.7% and 76.0%-81.2%, respectively, which were significantly higher than that in the control (second generation: 7.0%-12.3%, third generation: 5.2%-7.4%). And the injury rate of cotton buds and bolls in the second and third generation bollworm were 2.2% and 3.1%, respectively, which were significantly lower than that in the control (second generation:8.5%, third generation: 20.9%). In the second generation bollworm period, number of bollworm eggs or larvae in the Trichogramma released cotton field did not differ to that in the chemically controlled field. But in the third generation, there were significantly less bollworm eggs and larvae in the Trichogramma released cotton field. There were more predators in the Trichogramma released cotton field. These results indicated that cotton boll worm in the transgenic insect-resistant cotton field can he effectively controlled by mass-releasing of T.
结果发现:棉铃虫卵在棉株不同部位的分布差异较大,2代棉铃虫卵主要分布在叶正面、叶背面和茎尖,3代棉铃虫卵主要分布于蕾铃;在放蜂田,赤眼蜂对棉株不同部位棉铃虫卵的寄生率差异较大,2,3代棉铃虫时期对叶正面、叫背面、茎尖、蕾铃的棉铃虫卵寄生率均较高,对叶柄和茎杆处卵的寄生率较低;并以3代棉铃虫时期的寄生率较高;在2,3代棉铃虫时期分别连续释放3次赤眼蜂,对棉铃虫具有很强控制作用,2,3代棉铃虫卵的被寄生率分别为66.0%~70.7%和76.0%~81.2%,均显著高于化防田的自然寄生率(2代:7.0%~12.3%,3代:5.2%~7.4%);蕾铃被害率分别为2.2%和3.1%,均显著低于化防田(2代:8.5%,3代:20.9%;2代棉铃虫时期,放蜂田和化防田的棉铃虫卵量和幼虫数量差异均不显著,但3代棉铃虫以后,放蜂田棉铃虫卵量和幼虫数量均显著低于化防田,且放蜂田的捕食性天敌数量显著高于化防田。
