摘　　要：本文利用田间调查、室内饲养观察与强迫饲喂的方法,研究了新疆马铃薯甲虫发生区的捕食性天敌的种类,明确了捕食性天敌昆虫5目25种。室内初步研究了各种天敌昆虫对马铃薯甲虫的捕食量,结果表明不同种类天敌昆虫的捕食量的差异较大,脉翅目草蛉及半翅目蓝蝽、蝎敌、原姬蝽、华姬蝽对马铃薯甲虫的捕食量相对较大。Field investigation, laboratory observation and forced feeding method were used to research the species of predators against Leptinotarsa decemlineata Say in Xinjiang. There were twenty five species predatory insect which belonged to five orders. A preliminary study on the predatory capacity of these predatory enemies was carried out in the laboratory. There were obvious differences in predatory capacity among the different kinds of predatory insects, lacewing which belonge to Neuroptera as well as Zicrona caerulea （L.）, Arma chinensis （Fabricius）, Nabis （ Nabis ） fetus L, IV. （ Nabis ） sinoferus Hsiao which belonge to Hemiptera caught more L. decemlineata Say.
