Preliminary Investigation of Insect Pests in Mid-season Indica and Japonica Rice Fields of Xinyang Region
摘要
Abstract
Investigation and collection of rice insect pests were conducted in mid-season indica and japonica rice fields of the Xinyang region.By identification,187 specimens collected were divided into 8 orders,and 34 families.Chilo suppressalis,Cnaphalocrocis medinalis,Tryporyza incertulas,Sesamia inferens,Oxya chinensis,Nilaparvata lugens,Sogatella furcifera, Chloethrips oryzae,Haplothrips aculeatus were the dominant pests among them.Chloethrips oryzae and Cnaphalocrocis medinalis caused far more serious damage on japonica rice compared with indica rice,while Nilaparvata lugens and the third generation of Tryporyza incertulas caused less serious damage on japonica rice.The occurrence regularity of Chilo suppressalis changed from two generations to three generations per year because of the change in cropping pattern from indica to japonica rice.关键词
