农作物害螨的重要天敌——植绥螨类最适宜的生存条件是大气相对湿度较大,日照时数短和丰富的交替食料。广东柑桔面积大部分分布在丘陵及平原地带。柑桔园的大气相对湿度一般较小,日照长,周围植被单一。这样的生态特点有利于桔全爪螨Panonychus citri的发生而不利于植绥螨类种群的建立。因此,研究此类地区柑桔园的气候和食料对植绥螨类种群的影响和探讨利用植绥螨的可行途径是富有生产实 Crops mites important natural enemies - phytoseiidae most suitable living conditions are relatively large atmospheric humidity, short sunshine duration and rich alternate food. Most of the area of ​​citrus in Guangdong is located in the hills and plains. Citrus Orchard’s atmospheric relative humidity is generally small, long sunshine, surrounded by a single vegetation. This ecological feature is conducive to the occurrence of Panonychus citri, but not conducive to the establishment of phytoseiidae population. Therefore, studying the impact of climatic and foodstuffs on phytoseiidae populations in citrus orchards in such areas and exploring possible ways of using phytoseiosis mites are rich in production
