摘要
本文报道１９９４～１９９５年间，在上海进行的异色瓢虫Ｈａｒｍｏｎｉａａｘｙｒｉｄｉｓ（Ｐａｌｌａｓ）人工饲养及防治棚栽草莓蚜虫的初步研究结果。在室内以人工饲料喂养该种瓢虫成虫时，取得了良好效果。在蚜虫缺乏季节，它能完成正常发育，但对雌虫产卵量和卵的孵化率等方面受到一些影响。田间试验表明，用异色瓢虫防治草莓蚜虫，在瓢蚜比例为１：１００时，可以不用打药而能有效地控制蚜害。
The paper reported the result of a preliminary study on the artificial diet and controlling aphids of Harmonia axyridis (Pallas) conducted in Shanghai during 1994-95. The satisfactory result was obtained when this coccinellid fed with artificial diet in laboratory. It can be completed normal development in the aphid failure season. But the total amount of eggs laid and egg hatching rate, etc. were certainly affected. Field experiments showed that the strawberry aphids could be succesfully controlled by H.axyridis as a predator:prey ratio of 1: 100 in plastic covering without the need of insecticides.
