摘要
以砂梨（Ｐｙｒｕｓ ｐｙｒｉｆｏｒｉｓ Ｎａｋａｉ）叶作饲料，研究了２０、 ２２．５、 ２５、 ３０℃四种 温度和在２５℃条件下，６０％、７０％、８０％、９０％四种相对湿度对梨木虱Ｐｓｙｌｌａ ｐｙｒｉｓｕｇａＦｏｒｓｔｅｒ生长发育和繁殖的影响，结果表明梨木虱卵期、若虫期和全 世代生长发育最适温度分别为２０－２２．５℃，２２．５，２５℃和２２．５－２５℃，雌成虫繁殖 最适温为２５℃．生长发育和繁殖最适相对湿度为７０－８０％。
Pear leaf psylla psylla pyrisuga Forster were fed on Pyrus pyriforis Nakai leaves at 20-30℃and at 60-90% of relative humidity with 25℃. The results showed that the optimuM temperature for the development of the eggs,nymphs and the whole generation was shown to range from 20. 0-22.5℃, 22.5-25℃. and 22. 5-25℃， respectively. The optimun temperature for the reproduction of the female adults was 25℃. The optimum humidity for the development and reproduction of the pest was 70-80% of relative humidity.
