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.
