中文摘要：
双斑长跗萤叶甲 Monolepta hieroglyphica（Motschulsky) 已成为新疆北疆棉区的一重大新害虫，在室内5个恒温下（19、22、25、28和31℃）研究了温度对双斑长跗萤叶甲成虫寿命及生殖力的影响。结果表明，在19、22、25、28和31℃下雌雄成虫平均寿命分别为64.1、60.8、55.6、42.1和34.7 d，雌虫平均寿命明显长于雄虫；温度对雌成虫产卵前期、产卵期及产卵量有影响，在前述19～31℃ 5个温度下，其平均产卵量分别为29.2、82.1、93.8、73.4和63.1粒/雌。
英文摘要：The leaf beetle，Monolepta hieroglyphica ( Motschulsky) ，has become a new important pest in northern cotton planting region of Xinjiang. Effect of temperature on adult longevity and fecundity of M. hieroglyphica was analyzed at five constant temperatures (19，22，25，28 and 31℃ ) . The result showed that the average longevity of males and females was 64. 1，60. 8，55. 6，42. 1 and 34. 7 d at five constant temperatures，respectively. The longevity of females was longer than males slightly. The effect of temperature on pre-reproductive period， reproductive period and life-time mean fecundity of M. hieroglyphica was significantly. The mean life-time fecundity of M. hieroglyphica was 29. 2，82. 1，93. 8，73. 4 and 63. 1 eggs / female at five different temperatures，respectively.
