柑橘是世界上最重要的水果作物之一;然而，许多害虫和疾病影响果园，增加了生产成本。木虱Diaphorina citri是韧皮部限制性细菌“韧皮部细菌”的载体，黄龙病的病原。由于没有治愈HLB的方法，需要对病媒进行管理，主要是通过大量使用化学杀虫剂，从而选择耐药种群。我们的研究确定了昆虫病原真菌玫烟色虫草对D.在不同的时间点，通过喷雾施用真菌后的柑橘。应用电穿孔图技术监测D.柠檬在应用微生物产品后。喷雾后30 ~ 96 h的影响更为明显，与韧皮部相关的针口活动受到显著破坏，针口活动与HLB的传递直接相关。我们的研究表明，含有活性成分C.玫烟色孢菌能显著改变D.柑橘，可能有助于更可持续的管理载体，并可用于减少HLB的传播。
Citrus is among the most important fruit crops worldwide; however, numerous pests and diseases affect the orchards, increasing production costs. The psyllid Diaphorina citri, is a vector of the phloem-limited bacteria ‘Candidatus Liberibacter spp.’, the causal agent of Huanglongbing (HLB) disease. The lack of a cure for HLB requires management of the vector, mainly by intensive use of chemical insecticides, leading to the selection of resistant populations. Our study determined the effects of the entomopathogenic fungus Cordyceps fumosorosea on the probing behavior of D. citri at different time points after the fungus was applied by spraying. The electrical penetration graph technique was used to monitor the stylet activities of D. citri after application of the microbiological product. The effects were more pronounced between 30 and 96 h after the insects were sprayed, with significant disruption of the stylet activities related to the phloem and directly associated with the transmission of HLB. Our study indicated that the microbiological product Challenger®, with the active ingredient C. fumosorosea fungus, can significantly change the probing behavior of D. citri, may be helpful in more-sustainable management of the vector, and can be used to reduce the spread of HLB.
