稻水象甲对水稻危害损失及防治指标的探讨
The Losses Caused by Rice Water Weevil(Lissorhoptrus oryzophilus Kuschel) and the Threshold for its Control
【摘要】 为了有效地控制稻水象甲的危害,于1995~1996年进行了2a的扣笼接虫试验,通过计算分析,明确了不同虫口密度下稻水家甲对水稻生育及产量的影响情况,得出了稻水象甲的防治指标为30头/m2。
【Abstract】 Rice water weevil is an important pest in rice fields. Experiments have been carried out in rice seeding boxes for two years (1996~ 1997). The effectiveness of different pests intensities on rice yields was found out, which suggested that 30 rice water weevils per SM (square metre) was the control index.
