褐稻虱生物型问题使抗虫品种的选育和利用变得十分复杂。研究生物型形成的规律,用以指导抗虫品种的选育和利用是国际上引人注目的问题。本文根据以前的研究成果,按褐稻虱生物型的发生概况、褐稻虱生物型的特异性、褐稻虱生物型的形成等3个方面进行综合整理。为今后开展这方面研究提供参考。
The brown planthopper biotype problems make the breeding and utilization of insect-resistant varieties very complicated. It is an internationally attractive issue to study the rules of the formation of biotypes to guide the breeding and utilization of insect-resistant varieties. Based on the previous research results, this article summarized the occurrence of the brown planthopper biotype, the specificity of the brown planthopper biotype and the formation of the brown planthopper biotype. For future research in this area provide a reference.
