Hybridization Experiments on Three Biotypes of the Brown Planthopper, Nilaparvata lugens (Homoptera: Delphacidae) at the IRRI, the Philippines

Abstract

The genetic natures of three biotypes of the brown planthopper, Nilaparvata lugens, which possess different abilities to infest resistant varieties of rice, were studied by analyzing host preference response, feeding ability and nymphal development of the three biotypes and their inter-biotypic hybrid progenies. The results indicated that the biological traits of biotypes 2 and 3 were generally carried over in a recessive or intermediate way when they were hybridized with biotype 1. © 1981, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
