Frankliniella occidentalis (Pergande) is an important horticultural pest that causes serious damage to rose plants, which is one of its preferred foods. In this study, rose petals, rose flowers, and 10% honey solution + kidney bean pods were chosen as foods to assess their influence on the growth, development and fecundity of F. occidentalis. The results showed that developmental time of immature F. occidentalis with the following trend: rose flowers <10% honey solution + kidney bean pods < rose petals < kidney bean pods. The longevities of both female and male adults were lowest when feeding on the rose petals and were highest when feeding on rose flowers. The fecundity was in the following order: rose flowers >10% honey solution + kidney bean pods > rose petals > kidney bean pods. The net reproductive rate (R0), intrinsic rate of increase (r), and finite rate of increase (λ) of F. occidentalis feeding on rose petals and kidney bean pods were lower than those feeding on rose flowers and 10% honey solution + kidney bean pods. The development, longevity, fecundity, and parameters have significantly changed since F1 generation after feeding with the three food types. The results indicated that different parts of rose flowers had a significant effect on the development of thrips, and nectar and pollen had a positive effect on thrips population increase and reproduction.
西花蓟马（Frankliniella occidentalis (Pergande)）是一种重要的园艺害虫，会对玫瑰植株造成严重损害，玫瑰是其偏爱的食物之一。在本研究中，选取玫瑰花瓣、玫瑰花和10%蜂蜜溶液+菜豆荚作为食物，以评估它们对西花蓟马生长、发育和繁殖力的影响。结果表明，西花蓟马未成熟期的发育时间呈以下趋势：玫瑰花<10%蜂蜜溶液+菜豆荚<玫瑰花瓣<菜豆荚。雌雄成虫取食玫瑰花瓣时寿命最短，取食玫瑰花时寿命最长。繁殖力顺序如下：玫瑰花>10%蜂蜜溶液+菜豆荚>玫瑰花瓣>菜豆荚。取食玫瑰花瓣和菜豆荚的西花蓟马的净生殖率（R0）、内禀增长率（r）和周限增长率（λ）低于取食玫瑰花和10%蜂蜜溶液+菜豆荚的西花蓟马。用这三种食物类型喂食后，自F1代起，发育、寿命、繁殖力和参数均发生了显著变化。结果表明，玫瑰花的不同部位对蓟马的发育有显著影响，花蜜和花粉对蓟马种群增长和繁殖有积极作用。
