| 摘 要： | 【目的】研究棉蚜茧蜂对不同品种、不同生育期棉花的趋性行为反应,为了解天敌昆虫与寄主之间关系,利用棉蚜茧蜂对棉蚜等害虫进行防控。【方法】以生产上大面积种植的GK-12(对照为泗棉3号)、新棉33B(亲本为新棉33)和SGK321(亲本为石远321)等3组棉花品种为材料,于棉花7叶期、现蕾前期和现蕾期,设计无虫棉植株、被棉蚜为害后剔除虫体的植株以及棉蚜+有虫株等3种不同处理,借助“Y”型嗅觉仪,检测棉蚜茧蜂在棉花不同生育期对这3种不同处理的趋性。【结果】棉蚜茧蜂无法识别健康的常规棉和转基因棉花植株;对不含棉蚜的被害棉来说,转基因棉对棉蚜茧蜂更具吸引力。而对含有棉蚜的有害棉来说,除7叶期GK12、新棉33B和现蕾期GK12这3组处理外,其他各组的转基因棉对棉蚜茧蜂均具较强的吸引作用。【结论】两类不同的棉花品种对棉蚜茧蜂不存在排斥性,棉蚜为害转基因棉花后更能吸引棉蚜茧蜂。

| Abstract: | 【Objective】 With the large-scale cultivation of transgenic cotton, population of non-target pests such as Aphis gossypii Glover have been increased. Lysiphlebia japonica Ashmead is an important parasitic natural enemy which can control A. gossypii Glover efficiently.【Method】 To evaluate the performance of L. japonica Ashmead in transgenic cottons at different growth stages, three pairs of cotton varieties including GK-12 (its parental isoline: Simian 3), Xinmian 33B (its parental isoline: Xinmian 33) and SGK321 (its parental isoline: Shiyuan 321) were used. All the plants were divided into three treatments: health plants, plants infested by A. gossypii Glover and plants infested by A. gossypii Glover.【Result】 The results showed that L. japonica Ashmead was not able to distinguish the healthy transgenic cotton plants from healthy conventional cotton. L. japonica Ashmead preferred transgenic cottons to conventional cottons after both of them were damaged by A. gossypii Glover. In the aphid removal treatment, L. japonica was more attracted by all three Bt cotton varieties. However, more L. japonica chose the corresponding parental isolines when GK12 was in seven-leaves stage or bud stage and 33B was in seven-leaves stage.【Conclusion】 This research provides an important basis for the ecological safety evaluation of transgenic cotton and integrated pest management in cotton fields. |
