中文摘要：
【目的】 明确蜜源植物益母草Leonurus japonicus、向日葵Helianthus annus和罗勒Ocimum basilicum对中华淡翅盲蝽Tytthus
chinensis的影响，为筛选合适的蜜源植物并应用于田间提供理论基础。【方法】 在室内条件下，比较了益母草、向日葵以及罗勒的花对中华淡翅盲蝽寿命、产卵量和捕食量的影响。【结果】 益母草、向日葵以及罗勒的花都显著延长中华淡翅盲蝽雌虫（P < 0.001）和雄虫（P = 0.04）的寿命，其中，雌虫寿命分别为清水对照的1.35、1.36和1.33倍，雄虫寿命分别为清水对照的1.61、1.53和1.44倍，但对中华淡翅盲蝽雌虫产卵量没有显著影响（P = 0.239）。益母草、向日葵以及罗勒的花显著提高了中华淡翅盲蝽雌虫（P < 0.001）和雄虫（P < 0.001）捕食量，其中雌虫的捕食量分别为清水对照的1.73、1.53和1.95倍，雄虫的捕食量分别为清水对照的1.52、1.52和2.24倍。【结论】 益母草、向日葵以及罗勒能够显著增加中华淡翅盲蝽雌虫和雄虫的寿命和捕食量。本研究结果为稻田系统利用合适蜜源植物促进褐飞虱Nilaparvata lugens关键天敌中华淡翅盲蝽提供理论支持。
英文摘要：
[Aim] To evaluate the effect of the
nectar producing plants, Leonurus japonicus, Helianthus annuus,
and Ocimum basilicum, on the longevity, fecundity, and predatory
function, of Tytthus chinensis, an important natural enemy of the rice
planthopper, and thereby provide a theoretical basis for selecting nectar
producing plants that enhance the biological control function of T.
chinensis. [Methods] The
impact of the above nectar producing plants on the longevity, fecundity, and
predation rate of T. chinensis were compared under indoor conditions. [Results] Flowers of L. japonicus, H.
annuus, and O. basilicum significantly (P < 0.001)
extended the longevity of female T. chinensis by 1.35, 1.36 and 1.33
times, respectively, compared to the female control group, and male longevity
by 0.61, 0.53, and 0.44 times, respectively (P = 0.04), compared to the
male control group. However, flowers of these plant species had no significant
effect (P = 0.239) on the fecundity of T. chinensis females. The
flowers of L. japonicus, H. annuus, and O. basilicum significantly (P < 0.001) increased predation rate of female T. chinensis by 1.73,
1.53, and 1.95 times, respectively, compared to the female control, and that of
males by 1.52, 1.52, and 2.24 times, respectively (P < 0.001). [Conclusion] The nectar producing plants L. japonicus,
H. annuus, and O. basilicum significantly increase the longevity of both female and male T. chinensis and
the predation rate of both sexes of this species. Our results provide
theoretical support for using suitable nectar producing plants to
improve the performance of T. chinensis as a biological control agent.
