Citrus greening disease is devastating the citrus industry in Florida, and the conventional synthetic pesticide applications used to control the vector, the Asian citrus psyllid (AsCP), , are rapidly becoming unsustainable. Various laboratory experiments indicate that the entomopathogenic fungus , alone and in combination with horticultural oils, may offer a more sustainable strategy for the management of AsCP. Field studies conducted in 2018 and 2019 in mature citrus indicated that alone, mixed with white oil, and the chemical standard spinetoram mixed with white oil significantly suppressed AsCP adult populations by 61-83% up to 14 days after treatment in 2018, although colony-forming units of were still present on the leaves 21 days after treatment (DAT). Only spinetoram + oil significantly suppressed AsCP, by 100%, up to 7 DAT in 2019. Natural enemies of AsCP, including lady beetles, lacewing larvae and the parasitoid , were observed in the fungal treatments and the untreated control. The AsCP suppression by and its compatibility with beneficial organisms suggest the potential use of this entomopathogenic fungus in citrus-integrated pest management.
柑橘黄龙病正在摧毁佛罗里达州的柑橘产业，而用于控制传播媒介——亚洲柑橘木虱（AsCP）的传统合成农药应用正迅速变得不可持续。各种实验室实验表明，昆虫病原真菌单独使用以及与园艺油混合使用，可能为管理亚洲柑橘木虱提供一种更可持续的策略。2018年和2019年在成熟柑橘园进行的田间研究表明，单独使用该真菌、将其与白油混合，以及将化学标准药剂多杀霉素与白油混合，在2018年处理后长达14天内，均能显著抑制亚洲柑橘木虱成虫数量达61% - 83%，尽管处理后21天（DAT）叶片上仍存在该真菌的菌落形成单位。在2019年，只有多杀霉素 + 油在处理后长达7天内显著抑制亚洲柑橘木虱达100%。在真菌处理组和未处理的对照组中均观察到了亚洲柑橘木虱的天敌，包括瓢虫、草蛉幼虫和寄生蜂。该真菌对亚洲柑橘木虱的抑制作用及其与有益生物的兼容性表明，这种昆虫病原真菌在柑橘害虫综合管理中具有潜在用途。
