摘要
该文选择了青杨Populus cathayanaRehd.、华北落叶松Larix principis-rupprechtiiMayr.和山杏Aarmeniaca sibiricaLinn.,研究植物对舞毒蛾Lymantria disparL.生长发育历期、蛹重、产卵量的影响。结果表明舞毒蛾发育历期、蛹重及产卵量与所取食的寄主植物有明显的相关性,取食华北落叶松的舞毒蛾个体发育历期最短,平均为38.22±0.56 d,蛹最重,平均为1.48±0.09g,产卵量最多,平均每雌560.65±41.67粒;取食青杨的舞毒蛾发育历期最长,平均为46.68±0.65 d,蛹最轻,平均为1.17±0.08 g,产卵量最少,平均每雌315.47±49.07粒;取食山杏的舞毒蛾间于二者之间,平均历期为39.53±0.58 d,平均蛹重为1.24±0.08 g,每雌产卵量394.50±58.65粒。可以认为,在供试范围内华北落叶松最适宜舞毒蛾生长发育,山杏次之,青杨最不适宜。
Influence of host plants on the development duration, pupal weight and fecundity of Lymantria dispar was studied. Populus cathayana, Larix principis-rupprechtii and Aarmeniaca sibirica were used to feed gypsy moth larvae. The results showed that there were significant differences in the developmental duration, pupal weight and fecundity among the individuals feed on different host plants. Larvae fed on Larch had the shortest larval duration, weightier pupa and richer fecundity with a mean larval duration of 38.23 ± 0.56 d, mean pupal weight of 1.48 ± 0.09 g and mean fecundity of 560.65 ±41.67 eggs per female. Larvae fed on poplar had longer larval duration （mean duration was 46.68± 0.65 d）, lighter pupal weight（mean weight was 1.17 ± 0.08 g）. This indicated that gypsy moth preferred larch which was the most suitable host plant among the three.
