摘要
【目的】研究我国新疆伊犁河谷地区稻水象甲生物学及发生规律,为科学防治稻水象甲提供依据。【方法】对察布查尔县纳达齐乡等伊犁河谷主要水稻生产区稻水象甲的系统观察、调查,研究稻水象甲越冬习性、越冬场所、取食寄主出土后的种群转移规律和生活史。【结果】稻水象甲在伊犁河谷一年发生一代,4月下旬出土,5月上中旬迁入稻田,5月底至6月初为产卵期,6月为孵化期和幼虫危害期,7月上旬为化蛹期,7月中旬为新一代成虫期。【结论】明确了伊犁河谷稻水象甲主要生物学特性、发生规律,为监测和防治稻水象甲提供参考依据。
[Objective] Biology and binomics of the rice water weevil were investigated and studied in order to provide scientific and practical methods for controlling this pest.[Method] From 2009 to 2012,systematical investigations of the rice water weevil in five areas were conducted.These investigations involved the overwinter habit,places,the life cycle and the growth and decline law of the pest.[Result] The rice water weevil occur one generation a year in the Yili River Valley.Overwinter adults emerge in late April,and migrate to rice fields in early and middle May.Its ovipositor period goes from late May to early June.Larvae hatch out and damage rice in June.Larvae begin to pupate in early July,adults emerge in late July.[Conclusion] We clarified main biology characteristics and oeeurrenee regulation of the rice water weevil in the Yili River Valley,and these achievements will facilitate the monitoring and controlling of this pest.
