摘要
以砂梨ｐｙｒｕｓｐｙｒｉｆｏｒｉａＮａｋａｉ叶作饲料，在２０～３０℃下，梨木虱ＰｓｙｌｌａｐｙｒｉｓｕｇａＦｏｒｓｔｅｒ生长发育速率随温度升高而加快，发育历期缩短。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℃。卵期、若虫期、产卵前期和世代发育起点温度分别为—０．０３℃，３．８４℃，１０．５２℃和２．３３℃。
Pear leaf psylla(Psylla pyrisuga Forster)were fed on Pyrus pyriforis Nakai leaves at 20～30℃.The development of the insect was accelerated with the rise in temperature in the range of 20～30℃. The optimum temperature for the development of the eggs, nymphs and the whole generationwas shown to range from 20.0 ℃ to 22. 5℃, 22. 5℃ to 25℃ and 22. 5℃ to 25℃,respectively.The optimum temperature for the reproduction of the female adults was 25 ℃. The development ze-ro of the insect at the egg stage, nymphal stage,preoviposition stage and of the whole generationwas-0.03℃,3.84℃,10.52℃and 2.33℃,respectively.
