摘要
根据植绥螨食性的不同 ,可以采用叶螨、花粉和人工饲料等食物来培养植绥螨。规模化饲养植绥螨多用叶螨等害螨的寄主植物先繁殖害螨 ,然后在害螨中加入一些补充食物来大量生产植绥螨。张艳璇设计的袋栽法就是这样一套新的大量繁殖植绥螨的工艺方法。植绥螨的贮存目前都采用降低发育来实现 ,一般在 5～ 1 0℃的温度下能保存 5 0d以上。在田间按一定的比例释放抗药性的植绥螨 ,能够有效的控制二斑叶螨TetranychusurticaeKoch等害螨的发生。并且在地面鼓励种植覆盖作物、允许少量杂草生长或实行生草栽培 ,能够为植绥螨提供交替食物 ,从而更好地发挥生态控制功能的作用。
Phytoseiid mites were reared by tetranychus,pollen or artificial diet according to their different feeding habit. They may be reared in-mass by using additional food and injurious mites that had been reared before hand on their host plants. A new mass rearing method was designed by Zhang Yan-Xuan that phytoseiid mites and spider mites were reared by cultivated host plants in plastic bags.The phytoseiid mites, could be preserved over 50 days by lowing their development in 5～10℃.The phytoseiid mites resistant to pesticides could be released to control Tetranychus urticae and other injurious mites in the field efficiently.Cover crops and weeds could provide additional food for phytoseiid mites, so they are important in ecological control.
