| 摘 要： | 枸杞木虱是枸杞生产中4种严重害虫之一,在室内测定了枸杞木虱各虫态及整个世代有效积温和发育起点温度:卵期有效积温为90.2日度,发育起点温度为(7.2±2.4)℃;幼虫期的有效积温为291.8日度,发育起点温度为(8.4±2.9)℃;整个世代有效积温为547.6日度,发育起点温度为(7.9±2.0)℃。宁夏地区的年发生理论代数为3～4代,与实际观察结果基本吻合。

| Abstract: | Paratrioza sinica Yang et Li is one of the four pests in the production of Chinese wolfberry. The effective accumulated temperature and threshold temperature of P. sinica at different stages and in the whole generation were determined in this paper. The results showed that the effective accumulated temperatures of the egg, larva and the whole generation were 90.2, 291.8 day\|degrees and 547.6 day degrees, respectively, and the corresponding threshold temperatures were （7.2±2.4） ℃, (8.4±2.9) ℃ and (7.9±2.0) ℃, respectively . This pest was expected to occur 3-4 generations a year in Ningxia, which is coincided with the observations. |
