调查了山东省根结线虫的危害植物种类,以危害较重的4个不同用药水平地区的蔬菜根结线虫为研究对象,进行了形态学和酯酶同工酶谱鉴定,采用室内接触法和室内盆栽试验测定和比较了不同种群2龄幼虫对阿维菌素和辛硫磷的敏感性,并比较了保护酶的差异。山东省保护地蔬菜根结线虫为南方根结线虫Meloidogyne incognita,其危害的植物有51种,占调查总数的66.2%。2龄幼虫对阿维菌素的敏感性差异倍数为0.97～1.23、对辛硫磷为0.94～1.10,无显著性差异,其总体趋势为用药历史越长、用药量越多,药剂的敏感性越低;雌虫体内的可溶性蛋白存在细微差异,而POD和SOD同工酶谱带无显著差异。
The species of root-knot nematodes in Shandong Province were investigated. The root-knot nematodes of four different application levels were studied for their morphological and esterase isozymes. The indoor contact method and The indoor pot experiment was conducted to determine and compare the susceptibilities of the 2nd instar larvae to avermectin and phoxim. The protective enzymes were also compared. Meloidogyne incognita, a root-knot nematode in the protected area of Shandong Province, has 51 species of plants that are harmful, accounting for 66.2% of the total number of surveys. The second-instar larvae had a significant difference of 0.97-1.23 for abamectin and 0.94-1.10 for phoxim. The general trend was that the longer the history of drug use, the more the dosage, the sensitivity of the agent The lower the soluble protein in the female there are slight differences, and POD and SOD isozyme bands no significant difference.
