摘要
本文对印度谷螟的生物学和生态学特性进行了研究,结果表明:温度和相对湿度对印度谷螟的生长发育、繁殖和死亡有很大的影响,发育温度在16℃-36℃,发育适温在24℃-30℃,28℃为最适温度,相对湿度的影响没有温度的影响大,相对湿度在70%-80%,适合于印度谷螟的生长发育和繁殖,湿度太低对其生长发育不利.粮仓调查发现:在重庆地区印度谷螟一年发生5-6代,在6、7、8月份常有很大的种群数量,危害严重.
This paper deals with the biological characteristics of the Indianmeal moth, the range of suitable temperature is 24℃-30℃. 28℃ is the optimal. 70%-80% R.H.is suitable for the moth and a lower relative humidity is not a good condition for its development.The indian-meal moth takes place 5-6 generations in a year and great damage occurs daring Jane, July and August in Chongqing.
