寄生蜂毒液蛋白的研究进展 总被引:7,自引:0,他引:7
寄生蜂毒液蛋白具有抑制寄主血细胞免疫、调控寄主生长发育、抑制寄主生殖系统发育、调节寄主内分泌等功能,但一直以来对其组成成分知之甚少.近年来,不仅研究了寄生蜂毒液蛋白的生化特性,而且通过分离纯化、酶活测定、基因克隆等方法明确了寄生蜂毒液的部分蛋白组分.根据这些毒液蛋白性质和功能,可将其分为麻痹毒素、抗菌活性物质、酶类、酶的抑制剂等,它们在害虫生防、药理学和生理学研究中有着广阔的应用前景.该文作者就国内外对寄生蜂毒液蛋白组成成分的研究进展进行了综述,并对其应用前景进行了简要探讨. 相似文献

Many insects, especially nocturnal insects, exhibit positive phototaxis to artificial lights. Light traps are currently used to monitor and manage insect pest populations, and play a crucial role in physical pest control. Efficient use of light traps to attract target insect pests is an important topic in the application of integrated pest management (IPM). Phototactic responses of insects vary among species, light characteristics and the physiological status of the insects. In addition, light can cause several biological responses, including biochemical, physiological, molecular and fitness changes in insects. In this review, we discuss several hypotheses on insect phototaxis, factors affecting insect phototaxis, insect‐sensitive wavelengths, biological responses of insects to light, and countermeasures for conserving beneficial insects and increasing the effect of trapping. In addition, we provide information on the different sensitivities to wavelengths causing positive phototactic behavior in > 70 insect pest and beneficial insect species. The use of advanced light traps equipped with superior light sources, such as light‐emitting diodes (LEDs), will make physical pest control in IPM more efficient. © 2019 Society of Chemical Industry 相似文献
