| 摘 要： | 为验证人工释放赤眼蜂对水稻二化螟的防治效果,笔者于2012年开展了相关试验示范。蛾始盛期开始放蜂,放蜂面积6 670 m2,3次放蜂,总放蜂量30万头。试验结果表明,放蜂田虫伤株率2.63%~3.84%,加权平均为3.28%;防控效果为77.30%~84.73%,加权平均为79.62%。科学放蜂对控制水稻二化螟、保护水田的生态环境以及提高稻米品质有重要意义。

| Abstract: | The experiment and demonstration of artificially releasing Trichogramma japonicum were conducted in rice field to control Chilo suppressalis in 2012. Three treatments of parasitoids-releasing field, farmers’self-controlling field and contrast were set up in this experiment. The date of realising Trichogramma japonicum is during the beginning peak hatching period of Chilo suppressalis. The rice area is 6 670 m2 and 3 times releasing, the total amount of Trichogramma japonicum are 300 000. The results indicated that the average insect damaged plant rate was 3.28%, the average control effect was 79.62%. It is important to release Trichogramma japonicum to control the Chilo suppressalis, protect the ecological environment of paddy fields and improve rice quality. |
