With an aim to search for insecticides of good environmental quali-ty,experiments have been carried out on the application of the oil andextracts of the seeds of three species of Meliaceae for the oontrol ofcitrus insects in South China.Results of laboratory and field tests showedthat a spray of 1.4% emulsified neem (Azadirachta indica) seed oilshowed potential as a strong antifeedant for the control of the Asiaticcitrus psyllid (Diaphorina citri) which transmits the yellow-shoot di-sease.There is also some evidence to show that the oil exhibited contactaction and insect growth disruption effects on the nymphs of the psyl-lid.The neem seed oil and the petroleum ether extracts of the seed ker-nals of two species of chinaberry (Melia azedarach and M.toosendan)were effective against the citrus red-mite (Panonychus citri).A sprayof 1.4% neem seed oil also gave good control of the larvae of the cit-rus leaf miner (Phyllocnistis citrella). The unique properties of the seeds of some species of Meliaceae asa repellent and antifeedant,safe to the environment and to the naturalenemies of insect pest and compatability with the agroecosystem em-phasize its potential in the integrated control of citrus insect pests.

本文应用楝科植物(印楝、川楝、苦楝)种籽油及其抽提物对柑桔木虱及其他害虫进行一系列的忌避拒食及触杀作用试验,证明印楝油有明显的忌避及拒食作用。印楝油对柑桔潜叶蛾有良好的防效。印楝、川楝及苦楝油对柑桔红蜘蛛也有较强的触杀作用。应用楝科植物杀虫剂可兼治几种害虫,对人畜安全,不污染环境,不会引起抗药性的产生,而且对害虫天敌也比较安全。

This paper gives a critical review of toosendanin, including its source, isolation, physical and chemical properties,industrial production, toxicology to vertebrates and insects, with special emphasis on the potential of development as a novel class of botanical insecticides. As far as the authors are aware, the chinaberry tree Melia toosendan Sieb. et Zucc. is mainly found in China and toosendanin was first isolated in China .We are the first group working on toosendanin as an insecticide.

This paper gives a critical review of toosendanin, including its source, isolation, physical and chemical properties,industrial production, toxicology to vertebrates and insects, with special emphasis on the potential of development as a novel class of botanical insecticides. As far as the authors are aware, the chinaberry tree Melia toosendan Sieb. et Zucc. is mainly found in China and toosendanin was first isolated in China .We are the first group working on toosendanin as an insecticide. The unique properties of the toxic principles of toosendanin as an antifeedant, systemic and stomach poison as well as insect growth regulators, local availability, safe to the environment and com, patibility with the agroecosystem emphasize its ample potential in insect pest management system.

The insect growth regulator (TGRs), Dimilin and Benzophenol Urea No..3(1—(4—chloropheny) —3—(2—chlorobenzoyl) urea) have been shown to be effective against the. Armyworm( Mythimna sepatata walker)and several fruit pests. The objective of two IGRs to the adults, eggs, larvae and pupae of Leis axvridis(Pallas), Propylaca japonica(Thunberg) and Chrysopa sinica(Tjeder) have been taken in the laboratory and fields during . 1978—1982 in Gongzhuling, Jilin Province. Results of these studies indicated that toxicity of application of Dimilin at rates of 15, 25, 50g/ha(ai)and of Benzophenol Urea No.3 at rates of 75, 150 and 300g/ha(ai) were not significant to Leis axyridis(Pallas) and Propylaca japonica (Thunberg), but caused Significant mortality to Chrysopa sinica (Tjeder) . Treatment with Dimilin(applied at 30g/ha(ai) ) and BenzoPhenol Urea No. 3 (applied at 150, 300g/ha(ai) )in scale-feilds for controlling Armyworm did not appear adverse influence to lady beetles.

1978~1982年在公主岭,应用灭幼脲杀虫剂对天敌昆虫:异色飘虫Leis axyridis(Palas)龟纹飘虫Propylaca japonica(Tkunbers)、中华草蛉Chrysopa sinica(Tjeder)的成虫、卵、幼虫及蛹进行室内试验及田间调查。结果表明灭幼脲1号15、25、50克/公顷(有效成分,以下同);灭幼脲3号75、150、300克/公顷药量对异色瓢虫和龟纹瓢虫基本无影响,对中华草蛉杀伤严重。
