中文摘要:

为明确番茄褪绿病毒（ToCV）对其传毒介体烟粉虱Bemisia tabaci主要生物学特性的影响，本文研究了携带ToCV的Q型烟粉虱在非病毒寄主植物棉花Gossypium spp上的生物学指标，并测定了带毒和无毒烟粉虱主要保护酶和解毒酶活性。结果表明，在棉花植株上，带毒烟粉虱在发育历期、产卵量、成虫寿命方面与无毒烟粉虱无显著差异，但雌虫体长明显短于无毒烟粉虱。相对于无毒烟粉虱，带毒烟粉虱体内过氧化氢酶（catalase，CAT)活性明显提高，是无毒烟粉虱的3.36倍（P<0.001），超氧化物歧化酶（superoxide dismutase，SOD)和过氧化物酶（peroxidase，POD)活性无显著差异。解毒酶中，带毒烟粉虱羧酸酯酶（carboxylesterase，CarE)活性明显下降，是无毒烟粉虱活性的54%，谷胱甘肽S转移酶（glutathione-s-transferase，GST)和乙酰胆碱酯酶（acetylcholin esterase，AChE)活性无显著差异。

英文摘要:

To explicit the impact of Tomato chlorosis virus (ToCV) on main biological traits of its vector Bemisia tabaci, the biological parameters of B.tabaci Q infected by ToCV were detected on cotton (a non-host of the virus), and activities of main protective and detoxification enzymes were detected in B.tabaci Q virus infected and non-infected one. The results showed that the developmental period, fecundity and longevity were not different apparently between infected and non-infected B.tabaci. The body size of female adult of infected ones was shorter than non-infected ones. Compared to non-infected B.tabaci, activities of catalase (CAT) in infected B.tabaci increased to 3.36 times (P<0.001), while activity of superoxide dismutase (SOD) and peroxidase (POD) in infected B.tabaci didn't change significantly. In detoxification enzymes, carboxylesterase (CarE) activity in infected B-tabaci decreased significantly and which was only 54% of that of non-infected ones. Glutathione-s-transferase (GST) and acetylcholin esterase (AChE) showed no difference between infected and non-infected B.tabaci.
