我们在玛纳斯县调查害虫天敌时,发现当地农田有十多种瓢虫,其中以多异瓢虫、七星瓢虫、方斑瓢虫和深点食螨瓢虫数量最多,菱斑巧瓢虫、二星瓢虫、十三星瓢虫、十一星瓢虫和蓝瓢虫数量较少,双斑唇瓢虫、连斑毛瓢虫、四斑毛瓢虫以及其余几种瓢虫仅偶然见到。此外,食菌的廿二星瓢虫和食植的藜花瓢虫数量很多。据了解,北疆一些地方的情况也大致相同。这些瓢虫的成虫大都有图谱可资查对,但幼虫的识别尚少资料。为了保护和利用天敌,我们将8种食蚜瓢虫、深点食螨瓢虫、廿二星瓢虫和藜花瓢虫的幼虫形态进行了描述,以供田间识别时参考。
When we investigated the natural enemies of pests in Manas County, we found that there are more than ten kinds of ladybugs in the local farmland, among which, the ladybugs have the highest number of Ladybugs, Ladybugs, Ladybugs, Insects, two-star ladybugs, thirteen star ladybugs, eleven ladybugs, and blue ladybugs were fewer in number, with two-spotted ladybugs, even ladybugs, four ladybugs and the remaining ladybugs only occasionally See. In addition, there are a large number of twenty-two ladybugs and four resident ladybugs of ladybugs. It is understood that the situation in some parts of northern Xinjiang is also roughly the same. Most of the adults of these ladybugs are available for mapping, but larval identification is still poorly documented. In order to protect and utilize natural enemies, we described the morphology of larvae of 8 species of Aphis gossypii, Depth mites Ladybug, 22nd ladybug and Ladybug, for the reference of field identification.
