磷化铝和溴甲烷对稻水象甲熏蒸作用研究初报

A Preliminary Study on the Fumigation Effect of Aluminium Phosphide and Methyl Bromide on Rice Water Weevils

采用磷化铝、澳甲烷对用水象甲的薰蒸研究表明,在20℃以上,两种药剂处理稻谷对新一代成虫杀死100%群体的剂量和时间分别是1g/m^3-14h和35g/m^3-48h;处理稻草后杀死100%群体的剂量和时间分别为0.5g/m^3-16h和30g/m^3-16h.

The results on observation on the fumigating rice water weevils with aluminium phosphide and methyl bromide showed that when treating the paddy with the aluminium phosphide and methyl bromide at about 20℃,the lethal dosages and the corresponding durations for killing 100% adult populations of a new generation are 1g/m3, 14h and 35g/m3, 48h, respectively. When treating the straw with the two agents,the figures are 0. 5g/m3,16h,and 30g/m3,16h, respectively.
