不同品系抗刺吸式转基因棉对Q型烟粉虱生长发育的影响
Effects of different anti-piecing-sucking pests transgenic cotton lines on growth and developments of Bemisia tabaci biotype Q
摘要
Abstract
In order to evaluate the resistance effects of different anti-piecing-sucking pests transgenic cotton varieties on Bemisia tabaci biotype Q, we investigated the differences in body size, developmental duration, survival rate, adult longevity, fecundity and life-table parameters of B. tabaci biotype Q on 3 different anti-piecing-sucking pests transgenic cotton varieties and their corresponding maternal cotton varieties. The results showed that differences in most parameters including body size, developmental duration, survival rate and adult longevity were not significant between each transgenic cotton variety and its corresponding maternal cotton variety. But the fecundity of female adults and net reproductive rate ( Ro ) of population of B. tabaci on transgenic cotton varieties was significantly lower than that of its corresponding maternal line, respectively. The other life-table parameter, population doubling time (t) , was higher on each transgenic cotton line than on the corresponding maternal line. These results showed that the 3 anti-piecing-sucking pests transgenic cotton varieties were resistant to B. tabaci biotype Q. Furthermore, fecundity of female adults, net reproductive rate (R0) and popula-tion doubling time (t) could be 3 important indexes to evaluate the resistance effects of other transgen- ic cotton varieties on anti-sap-sucking pests.关键词
