摘要
通过对神泽氏叶螨ＴｅｔｒａｎｙｃｈｕｓｋａｎｚａｗａｉＫｉｓｈｉｄａ在不同温湿度条件下发育历期的观察，结果表明；３５℃，ＲＨ６０％完成一代需６．２３±０．４４ｄ；３０℃，ＲＨ６５％完成一代需１０．８９±０．５ｄ；２５℃，ＲＨ７０％完成一代需９．１６６±１．１４ｄ；２０℃，ＲＨ７５％完成一代需１５．９２±１．１ｄ；１５℃，ＲＨ８０％完成一代需２７．４９±２．２３ｄ。江西一年可能发生１３～１６代，发育起点温度为９．９５±０．７９℃，完成一代的有效积温为１６６±３．７７３日度。
This papet daals with the development spans of Tetranychus kanzawai kishida under dif-ferent temperature and humidity conditions.The results showed: at35℃ and RH 60% thespan of one generation was 6.23 ±0.44 days;30℃,RH 65% the span of one generation was10.89±0.5 days;25℃RH 70% the span of one generation was 9.16 6± 1.14 days; 20℃,RH 75% the span of one generation was 15.92 ±1.1 days;15℃,RH 80%the span of onegeneration was 27.49 ± 2.23 days. Tetranychus kanzawai may finish 13 to 16 generationsduring a year in Jiangxi Province. The starting temperature of its development temperature is9.95 ± 0.79 ℃,The total effective accumulated temperature for one generation is 166 ± 3.773day一degrees.
