genetic diversity of the planthopper, sogatella furcifera in the greater mekong subregion detected by inter-simple sequence repeats (issr) markers.the white backed planthopper, sogatella furcifera (hemiptera: delphacidae), is a serious pest of rice in asia. in the present study, inter-simple sequence repeat (issr) markers were employed to investigate the genetic diversity and differentiation of 47 populations sampled from 14 prefectures of the greater mekong subregion. a total of 14 selected primers yielded 121 bright and discernible bands, with an average of 8.6 bands per primer. according to the hierarchical analysis of molecular varianc ...201020569129
[insecticide resistance of different populations of white-backed planthopper, sogatella furcifera (horváth) (homoptera:delphacidae)].resistance to some insecticides used commonly in different populations of the white-backed planthopper, sogatella furcifera collected from zhejiang, guangxi, yunnan and hainan province in china was measured. the specific activities of some resistance-associated enzymes, i.e. esterase, carboxylesterase, glutathione s-transferase and acetylcholinesterase from these populations were also measured. the resistant levels to malathion, methamidophos, isoprocarb and buprofezin were markedly higher in yu ...200211962304
