(formerly known as ) Back (Hemiptera: Aleyrodidae), commonly known as pepper or solanum whitefly, is a new emerging whitefly pest of several horticultural crops in the United States. During the preliminary survey for pepper whitefly infestation in Florida, a whitefly-specific predatory beetle Horn (Coleoptera: Coccinellidae) was observed associated with this pest in the natural ecosystem. The current study was undertaken to determine the efficacy of this naturally occurring predator, , and an entomopathogenic fungus, (formerly known as ) () (Wize) (Hypocreales: Cordycipitaceae), alone or in combination, under controlled laboratory conditions. Whitefly mortality for (88%), beetle (100%) and + beetle (100%) treatments were similar and significantly higher compared to control. In the combination treatment, did not impact longevity and daily food intake, indicating a neutral interaction between the two treatments. Results showed that both of these natural biological control agents could potentially offer an effective alternative in the battle against invasive whiteflies such as pepper whitefly in U.S. horticulture production, either as a stand-alone strategy or in an integrated approach. Although these findings are promising, compatibility of the two treatments needs to be evaluated further under greenhouse and semi-field conditions before recommending to commercial growers.
（原名为 ）烟粉虱（半翅目：粉虱科），通常被称为辣椒或茄白粉虱，是美国几种园艺作物中新出现的粉虱害虫。在佛罗里达州对辣椒白粉虱侵染情况的初步调查中，在自然生态系统中观察到一种粉虱特有的捕食性甲虫——霍恩瓢虫（鞘翅目：瓢虫科）与这种害虫有关。当前的研究旨在确定这种自然存在的捕食者以及一种昆虫病原真菌——玫烟色棒束孢（原名为 ）（ ）（维泽）（肉座菌目：虫草科）单独或联合使用时在可控实验室条件下的效果。烟粉虱死亡率在 （88%）、甲虫（100%）和 + 甲虫（100%）处理中相似，且与对照相比显著更高。在联合处理中， 未影响 的寿命和每日食物摄入量，表明两种处理之间存在中性相互作用。结果表明，这两种自然生物防治剂在美国园艺生产中对抗入侵性粉虱（如辣椒白粉虱）的战斗中都有可能提供一种有效的替代方案，无论是作为单独的策略还是综合方法。尽管这些发现很有前景，但在向商业种植者推荐之前，需要在温室和半田间条件下进一步评估两种处理的兼容性。
