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。
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.
