摘要
甲基毒死蜱拌合小麦的生产试验,无论是采用砻糠载体法还是喷雾法施药,对防治米象类、锯谷盗和米虱等其效果都十分显著.而对照囤中在试验后期出现了大量米象类和米虱等害虫,但处理堆中只有少数的米象类和米虱. 室内生物测定表明,各处理堆中对玉米象的防治效果均可保持一年.和生产试验的结果一致,对于杂拟谷盗的防治效果是20ppm甲基毒死蜱和30ppm防虫磷相当.对于谷蠹10ppm甲基毒死蜱的效果与30ppm的防虫磷接近. 甲基毒死蜱不但对玉米象、杂拟谷盗和谷蠹的当代成虫的防治效果突出,而且对它们的第二代(F_1)也有显著的防治效果.
Chlorpyrifos-methyl has good efficacy on prevention of rice weevils, oryzaephilus surinamensis L. and Liposcelis bostrychophilus etc. Both methods of spray and manual husk carrier have the same effect.
A great numbers of rice weevils and L. bostryhophilus ect. occurred in the late experiment of the wheat without pesticide, and onlya few pests in the treatment. The results of laboratorial experiment showed that the Chlorpyrifos-methyl has efficacy on prevention of maize weevil during a year in all treatments and its effective dosage to Tribolium Confusum duv. and Rhizopertha dominica (Fab.) is 20ppm and 10ppm respectively, corresponding to 30ppm of malathion's.
The pesticide has also good efficacy on prevention of generations (F_1) of these pests.
