摘要
本文报道了史氏始叶螨的生物学特性及其防治。结果表明,史氐始叶螨完成一代需12～16,5天.卵历期5～6天,第一若螨期1.5天,第二若螨期1～1.5天。雌螨寿命10～13天,雄螨寿命6～7天。雌螨产卵期13～17天,总产卵量36～40粒。雌雄性比例为8:1。该螨发育起点温度为6.82℃,完成一代的总积温为204.67日度。在防治方面,使用12.290久效磷颗粒剂效果显著。
In this paper the biological characters and control of Eotetranychus smithi
were reported.The results showed that the generation of the spider mites was
12～16.5 days.The eggs stage was 5～6 days and the first nymphal stage 1.5
days,the second nymphal stage 1～1.5 days.The longevity of females was 10～13
days and the males 6～7 days.The oviposition stage of femal was 13～17 days.
The oviposition amout of femal was 36～40 eggs.The sex radio of females to
males was 8:1.The threshold of development temperature was 6.82℃,and the
effective constant temperature was 204.67 day degrees.In respect of control,
the usage of 12.5% monocrotopbos grannul was resultful.
