摘　　要：为探明两种不同寄主对桔全爪螨生长发育的影响,在实验条件[(26±1)℃,(70±5)%RH,10L∶14D]下研究测定了桔全爪螨在柑桔(脐橙)和花椒上的生长、繁殖、存活和生命表参数情况。结果表明,桔全爪螨在两种寄主植物上都能完成正常的生长发育,但二者间存在显著的差异。以脐橙叶为食的桔全爪螨和以花椒叶为食的桔全爪螨的每雌产卵量、净增殖力、内禀增长力、周限增长力大和种群加倍时间分别为40.33,11.76;14.67,7.41;0.185 7,0.129 0;1.204 1,1.137 8;3.73,5.37。以脐橙叶为食的桔全爪螨表现明显的生存优势,说明柑桔是桔全爪螨最为适宜的寄主。For the purpose of investigating the impact of two different host plants on the growth and development of citrus red mite,the development,reproduction and life table parameters of Panonychus citri(McGregor)are meas-ured and analyzed at26±1℃,70%±5%RH and a photoperiod of10:14(L:D)in the laboratory.The results show that the citrus red mite can grow and develop normally both on citrus and zanthoxylum.But,there are signifi-cant differences between the two host plants.The egg production per mite,value of R0,rm,X and t of the mite living on citrus and zanthoxylum leaves are40.33,14.67,0.1857,1.2041,3.73and11.76,7.41,0.1290,1.1378and5.37,respectively.The strong growth advantages of the mite living on citrus leaves indicate that citrus is the best host for P.Ctri.
