摘　　要：通过探讨木醋液对呋虫胺、螺虫乙酯两种内吸性药剂防治桃蚜是否有增效作用,为桃蚜的绿色防控提供一定的研究基础。测定了木醋液对两种药剂的增效作用和木醋液对桃蚜体内解毒酶活性的影响,并进行了木醋液与两种药剂复配后对桃蚜种群和盆栽药效试验。结果显示:1)5 mL/L木醋液对呋虫胺防治桃蚜的增效比达到了25.9,20 mL/L的木醋液对螺虫乙酯防治桃蚜的增效比达到了20.3。2)木醋液通过抑制桃蚜体内解毒酶(AChE、CarE)活性,桃蚜对药剂的降解能力减弱,从而利于两种药剂发挥药效。3)通过盆栽试验发现,稀释200倍的木醋液,对3种浓度呋虫胺桃蚜防效均有显著的增强,起到了增效作用。稀释100、200倍的木醋液均对螺虫乙酯桃蚜防效有显著提升作用。4)木醋液浓度过高会抑制小白菜植株生长,且木醋液抑制小白菜叶片合成叶绿素。对桃蚜种群的主要影响是,降低了种群增殖力。综上,木醋液可作为一种绿色增效剂来延缓桃蚜对螺虫乙酯和呋虫胺的抗药性并增强防治效果。Through exploring whether wood vinegar has a synergic effect on the control of Myzus persicae with two kinds of internal absorption agents,dinotefuran and spirulin ethyl,so as to provide certain research basis for green control of Myzus persicae.The synergistic effect of wood vinegar on two pesticides was determined,and the effect of wood vinegar on the detoxification enzyme activity in Myzus persicae was also measured.The efficacy of wood vinegar combined with two pesticides on Myzus persicae populations and potted plants was then tested.The results show that:1)The synergic ratio of 5 mL/L wood vinegar to dinontefuran control Myzus persicae was 25.9,and the synergic ratio of 20 mL/L wood vinegar to spiralate control Myzus persicae was 20.3.2)Wood vinegar reduces the resistance of Myzus persicae to insecticides by inhibiting the activity of detoxifying enzymes(GST,AChE,CarE)in their bodies,thereby facilitating the effectiveness of the two insecticides.3)Through pot experiment,it was found that the wood vinegar diluted 200 times significantly enhanced the control effect of dinotefuran at three concentrations against Myzus persicae,and played a synergistic role.The wood vinegar diluted by 100 or 200 times has a significant improvement on the control of spirochete against Myzus persicae.4)High concentration of wood vinegar could inhibit the growth of Chinese cabbage plants,and wood vinegar inhibits the synthesis of chlorophyll in chinese cabbage leaves.The main impact on the Myzus persicae population is a decrease in population fertility.In conclusion,wood vinegar can be used as a green synergist to delay the resistance of peach aphid to spiralate and dinotefuran and enhance the control effect.
