采用EtF处理3个品系的锈赤扁谷盗,EtF能快速杀死试虫,但杀虫效果随温度的升高而降低,试虫对EtF的耐受力与对PH3的抗性有相同的趋势;锈赤扁谷盗成虫对EtF的忍耐力强于幼虫,使用EtF分别与PH3和CO2混合熏蒸处理锈赤扁谷盗。结果表明:EtF对PH3和CO2有明显的增效作用。
EtF can kill the test insects rapidly with EtF, but the insecticidal effect decreases with the increase of temperature. The resistance of the test insects to EtF is the same as that of PH3 The trend of tolerance to EtF was stronger than that of larvae on EtF, and EtF was mixed with PH3 and CO2 to fumigate rusty flat-bottom steal. The results showed that: EtF on PH3 and CO2 have obvious synergies.
