摘　　要：泽漆(Euphorbia helioscopia)为大戟科(Euphorbiaceae)大戟属(Euphorbia)植物,全株含有丰富的白色乳汁,有毒,在国家高质量发展和“新农科”建设背景下,探寻泽漆在杀虫农药开发中的潜力显得尤为重要。在室内毒力测定的基础上,采用离体叶片植物介导法研究了泽漆乳浆亚致死剂量(LC35、LC25、LC15)对豌豆蚜(Acyrthosiphon pisum)生长发育和繁殖的影响。结果表明,泽漆乳浆不同亚致死剂量LC35、LC25、LC15(1.380 g/L、0.847 g/L、0.460 g/L)对豌豆蚜的生长发育和繁殖均有显著影响。经不同亚致死剂量处理后,豌豆蚜若蚜发育历期明显缩短,而成蚜期、产蚜天数明显延长,平均产蚜量和日均每雌产蚜量与对照相比均明显降低。在LC35剂量处理下,豌豆蚜若蚜发育历期最短(5.74 d),成蚜寿命(20.08 d)和产蚜历期(17.06 d)最长,平均产蚜量(86.35头)和日均每雌产蚜量(5.07头)最低。结果表明,泽漆乳浆亚致死剂量对豌豆蚜的生长发育具有促进作用,而对豌豆蚜成蚜生殖力有显著的抑制作用。Euphorbia helioscopia is a plant of the family Euphorbiaceae and genus Euphorbia,and the whole plant is rich in white latex,which is poisonous.In the context of national high⁃quality development and the construction of“new agricultural science”,it is particularly important to explore the potential of E.helioscopia in the development of insecticidal pesticides.In this study,the effects of sublethal doses(LC35,LC25,LC15)of E.helioscopia latex on the growth,develop⁃ment and reproduction of Acrythosiphon pisum were investigated by in vitro leaf plant mediated method on the basis of in⁃door virulence determination.The results showed that different sublethal doses of LC35,LC25 and LC15(1.380 g/L、0.847 g/L and 0.460 g/L)of E.helioscopia had significant effects on the growth,development and reproduction of A.pisum.After treatment with different sublethal doses,the developmental period of A.pisum nymph was significantly shortened,while the adult period and aphid production days were significantly prolonged.The average aphid production and daily aver⁃age aphid production per female were significantly reduced compared to the control group.Under the LC35 dosage treatment,A.pisum nymph had the shortest developmental duration(5.74 d),and adult aphids had the longest lifespan(20.08 d)and aphid reproduction period(17.06 d),while the average aphid production(86.35)and daily average aphid production per female(5.07 aphids)were the lowest.The results indicate that the sublethal doses of E.helioscopia latex have a promoting effect on the growth and development of A.pisum,while significantly inhibiting reproductive ability of its adult aphids.
