摘要
在30℃±1℃,70%±5%R.H.的条件下,研究90%、95%和98%浓度的氮气对储粮害虫的控制效果,结果表明:90%以上的氮气浓度均可以控制各试虫成虫产生下一代;95%和98%的氮气均可用于储粮害虫的防治,但95%氮气控制害虫需要气调的时间较长,需要根据实际防治时的经济阈值进行选择;98%氮气对各虫种均有较好的控制效果。氮气气调可用于对PH3抗性害虫的防治。
At 30℃± 1℃ and 70% ± 5% R.H.,nitrogen concentration of 90%,95% and 98% was used in the study for control the stored grain insects.The results showed that the nitrogen concentration over 90% could control the adult insects from producing the next generationcan.95% and 98% of the nitrogen concentration could be used to control stored grain insects.For 95% of the nitrogen required a longer time to control the insects,it should be selected according to the economic threshold from practice.98% concentration could control all pests effectively.Nitrogen can be used to control the PH3 resistance pests.
