Abstract excerpt
Allozyme variation was studied in three Nilaparvata lugens biotypes infesting specific rice varieties and a biotype infesting a weed grass, Leersia hexandra. Of the 20 enzymes in N. lugens for which activity was noted, 9 were polymorphic. Eleven enzyme loci were monomorphic for the same allele in all biotype populations; the rest were polymorphic for two or more alleles. The mean number of alleles per polymorphic...
