摘要 在 2 5℃恒温条件下 ,以盆栽玉米、小麦、高粱、水稻、谷子、大麦及虮子草为食料 ,研究了食物对二点叶蝉实验种群生长发育及繁殖的影响 .结果表明 ,二点叶蝉在虮子草上不能完成世代发育 .在其余 6种寄主植物上各虫态的发育历期、存活率、雌成虫寿命及单雌平均产卵量存在显著差异 .从卵到若虫期的发育历期在高粱上最短 (2 4 1d) ,玉米上次之 (2 4 2d) ,小麦上最长 (2 5 5d) ;取食水稻时 ,若虫的存活率(4 0 8% )最低 ,成虫寿命最短 (12 2d) ,单雌平均产卵量 (12 3粒 )也显著低于其它 5种寄主植物 .用生命表参数综合评价表明 ,6种寄主植物中 ,谷子和玉米最适合二点叶蝉生长发育及繁殖 ,其次分别为高粱、大麦、小麦、水稻 . The study on the development,survivorship and fecundity of Cicadulina bipunctella reared on corn,wheat,sorghum,rice,millet,barley and Leptochloa panacea showed that the insect could develop and reproduce on all test host plants except for Leptochloa panacea.The development duration of C.bipunctella at its immature stages reared on sorghum was the shortest(24.1 d),then on corn (24.2 d),and the longest on wheat (25.5 d).The survival rate (40.8%),longevity (12.2 d) and oviposition per female (12.3 eggs) of female adults reared on rice were lower than those reared on the other five host plants.Based on the life-table parameters,the most suitable host plants for the development and reproduction of C.bipunctella were millet and corn,followed by sorghum,barley,wheat and rice.
