    This paper gives a concise introduction of insect-plant relationships, the recent development on the investigations of botanical insecticides, the chemistry of plant resistance to insects in relation to the breeding of resistant varieties, and the active defense of plants against insect attack in relation to insect control.These four problems are closely interrelated. The discussions were mainly based on the biochemistry and ecology point of view and some of the results of research on botanical insecticides relevant to this area recently carried out in the Laboratory of Insect Toxicology,South China Agricultural Univsrsity were presented. In forecasting of insect outbreaks the authors pointed out that usually methematical models upon which predictions were based centered on two major assumptions. One was the fluctuations in weather acted as the main determination of insect abundance and the other had to do with the interplay of such biological factors as parasites, predators, and pest pathogens. These predictive models sometimes failed because they were predicted on the belief that plants played a totally passive role in population dynamics, while in fact, it is the plant that is really pulling the strings. In China, investigations on insecticides from natural products and the defense mechanisms of plants to insect attack undoubtedly lead to breakthroughs in the system of integrated pest management (IPM) .

    本文介绍了植物与昆虫之间的关系、植物杀虫剂最近研究的进展、植物抗虫性的化学及其在抗虫育种中的作用、植物对昆虫的主动防御及其在害虫防治中应用的展望。主要从生物化学及生态学方面进行讨论,指出这四个问题具有内在的联系。对植物杀虫剂的探入研究,今后可能获得对环境安全而对害虫不产生抗药性的新一代农药。研究作物抗虫的遗传基因,可以培育出高抗优良品种。对于植物对害虫主动防御的探索,可以在害虫预测预报上获得新的进展。作者认为在我国开展植物自身控制害虫作用的研究具有深远的意义,将可使害虫综合防治获得划时代的突破。

    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.

    本文对川楝素的来源、发现、提制、生产、应用及药理、毒理、毒性等方面的研究历史、现状及展望作了简单叙述。旨在讨论进一步研究这一天然化合物的重要意义。特别是通过对川楝素在医学上的药理、毒性等方面研究成果的回顾、总结,而为深入研究其在害虫防治方面的作用机制及应用措施提供依据、寻找线索、开创思路。

    Results of laboratory and field experiments with mixtures of toosendanin, Bacillus thurin-giensis (B. t.), B. t. No. 6 (containing 0.05% cypermethrin), etlianol extract of the root-bark of the thunder-god-vine (Trypterygium tvilfordii Hook f.) or chlorpyrifos showed marked synergistic effects in controlling the damage of the cabbage worm.

    Results of laboratory and field experiments with mixtures of toosendanin, Bacillus thurin-giensis (B. t.), B. t. No. 6 (containing 0.05% cypermethrin), etlianol extract of the root-bark of the thunder-god-vine (Trypterygium tvilfordii Hook f.) or chlorpyrifos showed marked synergistic effects in controlling the damage of the cabbage worm. It was found that although the conventional organic insecticides such as cartap, chlorpyrifos exhibited a rapid toxic action against the. cabbage worm, yet those survived the treatment fed and developed normally, and the weight of the pupae was similar to that of the unreated larvae. With botanical insecticides, however, either applied alone or in admixture with other insecticides, the percentage of pupation was significantly decreased in the larvae which survived the treatments and interestingly, the weight of the pupae was found to be markedly lighter, than the untreated control. This discovery seems to indicate that the toxic principles of the botanical insecticides, such as toosendanin and Trifterygium alkaloids would possess growth disrupting properties against the cabbage worm and furthermore it may have far-reaching importance in studying the mechanism and genetics of insecticide-resistance. .

    川楝素分别与苏芸金杆菌(B.t. var.galleriae)、青虫菌6号、雷公藤根粉乙醇抽提物以及化学农药乐斯本混用,对保护作物避免菜青虫(Pieris rapae L.)幼虫的取食为害有明显的增效作用,而且对幼虫的化蛹及蛹重都有明显的仰制作用,具有理论和实际意义。
