甲酸乙酯熏蒸菜豆象的初步研究
发布时间：2018-10-20 16:45
【摘要】：本文利用广口瓶密闭熏蒸法,测定了不同浓度、时间和温度条件下甲酸乙酯对菜豆象的熏蒸效果。结果表明:选用浓度为45μL/L处理24 h或50μL/L处理12 h,均能使其成虫达到90%以上的死亡率,说明甲酸乙酯具有良好的速效性;菜豆象的熏蒸效果随熏蒸浓度的增加、温度的升高和时间的延长而逐渐增强;各虫态耐药性比较表明:甲酸乙酯浓度的高低对菜豆象各虫态耐药性影响较大,低浓度下卵的耐药性最差,而高浓度下成虫和卵的耐药性最差。
[Abstract]:In this paper, the fumigation effect of ethyl formate on bean weevil at different concentration, time and temperature was determined by sealed fumigation in jar. The results showed that the treatment of 45 渭 L / L for 24 h or 50 渭 L / L for 12 h could increase the mortality of adult worms to more than 90%, which indicated that ethyl formate had a good quick effect, and the fumigation effect of bean elephant increased with the increase of fumigation concentration. The increase of temperature and the prolongation of time showed that the concentration of ethyl formate had a great influence on the resistance of bean weevil, and the resistance of eggs at low concentration was the worst. The resistance of adults and eggs at high concentration was the worst.
