title: [Host plant suitability and reproductive isolation of two Schizotetranychus bambusae populations from the bamboo species Phyllostachys pubescens and Neosinocalamus affini].
abstract: Development, survivorship, reproduction and procreation isolation of Schizotetranychus bambusae from the bamboo species Phyllostachys pubescens and Neosinocalamus affinis reared on different host plants were evaluated in laboratory. The results showed that the population of S. bambusae from Phyllostachys pubescens (PhS) failed to complete its life cycle when reared on the leaf of N. affinis. When the population of S. bambusae from N. affinis (NeS) was reared on the leaf of P. pubescens, the survivorship and fecundity decreased. The rm, lambda and Ro were 0.0391, 1.0399 and 2.5542, respectively. At 27 degrees C, when the PhS was reared on P. pubescens, rm, lambda and Ro were 0.1415, 1.1520, and 15.6298, respectively, whereas NeS was reared on N. affinis, rm, lambda, and Ro were 0.0993, 1.1044, and 10.0622, respectively. Reciprocal cross test between PhS and NeS showed tht the two populations could mate, but laid unfertilized eggs that produced male only, indicating the existence of reproductive isolation.
