| 摘 要： | 根据室内饲养观察结果估测,枸杞负泥虫LemadecempunctataGebler各虫态的发育起点温度分别为卵期(7.8±2.2)℃,若虫期(7.6±2.1)℃,预蛹期(8.1±0.9)℃,蛹期(9.3±3.0)℃,产卵前期(8.2±3.2)℃;有效积温分别为卵期88.4日·度,若虫期138.3日·度,预蛹期71.3日·度,蛹期65.9日·度,产卵前期126.8日·度;全世代的发育起点温度为(7.7±1.9)℃,有效积温为526.8日·度。根据有效积温法则推算,枸杞负泥虫在宁夏地区年发生理论代数为3.81(代),与实际观察结果基本吻合。

| Abstract: | The developmental threshold temperature of Lema decempunctata Gebler for egg, larva,prepupa,pupa,adult and whole generation were determined as (7.8±2.2)℃,(7.6±2.1)℃,(8.1±0.9)℃,(9.3±3.0)℃, (8.2±3.2)℃ and (7.7±1.9)℃, respectively. The corresponding effective accumulated temperatures each stage were 88.4,138.3,71.3,65.9,126.8 and 526.8 degrees-day respectively.The yearly occurring generation number of the insect pest predicted by effective accumulated temperature was 3.81 in Ningxia Region,which was consisotent with the records in field. |
