The effect of artificial feed of Harmonia axyridis
Abstract：With the concept of green plant protection, natural enemy insects are more and more important in agricultural production.As one of potential natural enemy insects, Harmonia axyridis have already got our attention. Harmonia axyridis belong to coleoptera, ladybirds insects, was originally found in Asia. because of its strong ability in pest control, Harmonia axyridis was artificial introduced to all over the world. Large-scale breeding of Harmonia axyridis to improve the quality of important crops and promote ecological agriculture plays an important role in promoting. This experiment consisting of two insect state (adult male and female adult) aims to determine the ability of this kind of insect prey, the results showed that food conditions have no significant impact on the two kinds of adult feeding, which may be associated with the choosed insect age.In addition, the predator - prey effect of two species was also calculated by using the model, which was of great significance to the timely release of Harmonia axyridis and its control effect.

人工饲料对异色瓢虫捕食效应的影响
异色瓢虫是常见的一种捕食性瓢虫，在我国很常见，在俄罗斯、蒙古、朝鲜和日本等地也比较常见，所以，异色瓢虫又称为亚洲瓢虫。有关异色瓢虫的色斑变型的研究有很多，从瓢虫外观到基因对色斑类型的控制都有非常详细的研究[1-4]；异色瓢虫色斑变形的特性在其生物防治方面，近年内已有广泛的应用，但是对异色瓢虫进行大规模的人工饲料饲养并且将其用于生物防治，国内外还没有成功的先例。
随着我国现代农业发展，对无公害绿色农业要求的不断提高，要通过使用捕食性昆虫防治田间的植食性害虫已成为我国植保工作中的一项重要组成部分。异色瓢虫作为一种捕食性优势种瓢虫，具有捕食范围大，食量大，产卵量大的优点，可成为田间有效防治害虫的手段。但目前由于缺少有效的人工饲料，昆虫源饲料的获得又费时费力，因此异色瓢虫的产量极为有限，极大的限制了异色瓢虫在农业害虫防治上的运用[5.6.7]。
