通过分析总结湖北省水稻三化螟48a中发生为害的消长演变和防治措施的发展变化,进一步认识了三化螟发生为害的年度间演变规律和周年发生规律。认为冬春气候(气温、雨量)、水稻栽培制度和中稻生育期等因素与三化螟为害密切相关。并从治螟技术的发展历程提出了合理选择药剂、改善施药方式、发挥天敌自然控制作用的治螟策略。
By analyzing and summarizing the development and changes of the growth and development of the rice stem borer, Chilo suppressalis (Walker) (Chilo suppressalis), and the control measures, the evolution and the annual occurrence of the yellow rice borer (Chilo suppressalis) were further studied. It is concluded that the winter and spring climate (temperature, rainfall), rice cultivation system and middle-season rice growth stage are closely related to the damage of the rice stem borer. And from the development history of rice borer technology, we proposed a strategy of controlling rice borer with rational selection of pesticides, improvement of pesticide application and natural control of natural enemies.
