This dissertation studied biochemical characters of enzymes associated to op resistance in field populations of locusta migratoria manilensis ( meyen ) from huanghua - hebei, pingshan - hebei, beidagang - tianjin and wudi - shandong, where the insecticide selection pressures are considered different
本文選取我國東亞飛蝗河北黃驊、河北平山、天津北大港和山東無棣四個殺蟲劑選擇壓力不同的東亞飛蝗自然種群進行有機磷抗性相關酶的生化特性研究。 -
The two areas are important in locust control in china because of the frequent massive outbreaks of locusta migratoria manilensis ( meyen ). the selection pressure of op was found higher in huanghua - hebei and beidagang - tianjin than in pingshan - hebei and wudi - shandong. ld50 values for malathion of huanghua - hebei and beidagang - tianjin are higher than those of pingshan - hebei and wudi - shandong
天津北大港、河北黃驊及河北平山三種群對馬拉硫磷的ld _ （ 50 ）值分別是山東無棣種群的1 . 96 、 1 . 8及1 . 02倍，這說明，我國重點蝗區殺蟲劑的選擇壓力已經造成當地東亞飛蝗種群對常用殺蟲劑的敏感性下降。
