【摘要】 初步试验结果表明:小麦吸浆虫(Sitodiplosis mosellana Gehin)活动幼虫化蛹和成虫羽化。在室温日均温度19.1℃下,适宜的土壤含水量范围为17—25%,最适土壤含水量为22—23%。在湿度(土壤含水量20%左右)满足的条件下,最适宜的温度为22℃,低于20℃高于24℃活动幼虫化蛹和成虫羽化百分率明显下降。不论温、湿度条件适宜与否,在幼虫中普遍存在着一部分不化蛹羽化的滞育幼虫。更多还原

【Abstract】 Results from primary experiment show that the pupaton of activae larvae and the emergence of adults of Sitodiplosis mosellana Gehin required an average daily roomtemperature of 19.1℃ and a corresponding soil moisture of 17-25%, with a most suitable range of 22-23%. When the Soil moisture was satsfactroy (about 20%), the temperature at 22℃ was favowable. Below 20℃ or above 24℃, the rate of larvae pupation and adult emergence apparently dropped down. However, there was usually a part of larvae, diapause larvae, that could not purate or emerge.更多还原
