摘　　要：通过桉树枝瘿姬小蜂Leptocybe invasa产卵危害、针刺损伤和外源茉莉酸甲酯(MeJA)喷施等不同诱导桉树Eucalyptus spp.抗性处理,测定桉叶中与化学防御相关生理生化物质的变化,并用模糊相似优先比法分析比较不同诱导方式对受害植株上的桉树枝瘿姬小蜂的生长发育、繁殖力和种群趋势等生物学指标的影响,综合评价桉树诱导抗性的抗虫效果。结果表明:对桉树植株喷施1.0 mmol·L-1MeJA诱导处理,能够诱导桉树植株产生与桉树抗桉树枝瘿姬小蜂危害较为相似的化学防御效果,证明了喷施外源MeJA在诱导抗性中有积极的作用,可作为该害虫综合治理的一种有效的手段。Through different induction treatments, such as Leptocybe invasa damage, mechanical damage,and exogenous methyl jasmonate(MeJA) spraying, we had measured changes of physiological and biochemical substances in eucalyptus leave which play a role as chemical defense to the wasps. By different induction treatments, the effects on indicators of the growth, development, reproductive activity and population trends of L.invasa were studied by the method of fuzzy similitude priority. The results showed that: Vague comparative method on similarity evolution between oviposition-induction and other induction treatments, showed that spraying 1.0 mmol·L-1MeJA can make the similar result as oviposition, demonstrated spraying MeJA plays an active role in induced resistance, which can be used as the supplementary method for integrated pest management to the wasps.
