Abstract
Nine populations of three species ofNephotettix (Insecta: Hemiptera) from Peninsular Malaysia were analysed for nine enzymes comprising 11 loci. Nei's (Genetics 89, 583, 1978) genetic distance,D, betweenN. virescens andN. malayanus was 0.181, that betweenN. virescens andN. nigropictus was 0.283, and that betweenN. malayanus andN. nigropictus was 0.203. The genetic distance betweenN. nigropictus from rice plant and from the weed-grassL. hexandra at Universiti Pertanian Malaysia was 0.004 and their genetic identity was 0.996, thus indicating that this insect species feeds on both host plants. The proportion of polymorphic loci and the observed heterozygosities were higher inN. nigropictus, with a wider range of host plants, than inN. virescens andN. malayanus, restricted to rice andL. hexandra, respectively.
