从Cacopsyllasp中分离到一种新的、但尚未发表的昆虫病原真菌(ARSEF13372)。(半翅目：木虱科)。假丝酵母属的几种韧皮部细菌，可引起果树的病害，如苹果繁殖、梨衰退和欧洲核果黄化。为了确定潘多拉的寄主范围和生防潜力，我们进行了实验室侵染生物测定；半翅目韧皮部取食昆虫暴露于标准化地区培养的菌丝垫上主动释放的分生孢子。我们记录了Pandorasp.nov的致病性。在昆虫科昆虫中，分别命名为Cacopsylla和Triozidae，Cacopsylla，Pricola(Foerster)，C.Pickta(Foerster，1848)，C.pruni(Scopli)，C.peregrina(Foerster)和Trioza apicalis Foerster。在接种后10天内，身体上出现了感染的身体体征，证明了潘多拉普。11月在实验室条件下，对供试昆虫种类具有侵染性，显著缩短了白纹伊蚊(夏季形态和若虫)、白纹伊蚊、白纹伊蚊、普鲁尼白纹伊蚊、白纹伊蚊和白粉虫的平均存活时间。对植原体、真菌和昆虫寄主之间的潜在相互作用进行了评估，结果表明，介体苹果和/或其寄主植物苹果的植原体感染(‘Candidatus Phytodium Mali’)。并未显著影响FC的存活率。11月感染。感染生物检测结果与潘多拉普的关系进行了讨论。11月寄主范围及其作为生防剂在果园木虱害虫综合治理策略中的适宜性
A new but still unpublished entomopathogenic fungus (ARSEF13372) in the genusPandora(Entomophthorales: Entomophthoraceae) was originally isolated fromCacopsyllasp. (Hemiptera: Psyllidae). Several species of the genusCacopsyllavector phloem-borne bacteria of the genus ‘CandidatusPhytoplasma‘, which cause diseases in fruit crops such as apple proliferation, pear decline and European stone fruit yellows. To determinePandora’s host range and biocontrol potential we conducted laboratory infection bioassays; Hemipteran phloem-feeding insects were exposed to conidia actively discharged fromin vitroproduced mycelial mats of standardized area. We documented the pathogenicity ofPandorasp.nov. to species of the insect families Psyllidae and Triozidae, namelyCacopsylla pyriL.,C. pyricola(Foerster),C. picta(Foerster, 1848),C. pruni(Scopoli),C. peregrina(Foerster), andTrioza apicalisFoerster. The occurrence of postmortem signs of infection on cadavers within 10 days post inoculation proved thatPandorasp. nov. was infective to the tested insect species under laboratory conditions and significantly reduced mean survival time forC. pyri(summer form and nymph),C. pyricola,C. picta,C. pruni,C. peregrinaandT. apicalis. Assessing a potential interaction between phytoplasma, fungus and insect host revealed that phytoplasma infection (‘CandidatusPhytoplasma mali’) of the vectorC. pictaand/or its host plant appleMalus domesticaBorkh. did not significantly impact the survival ofC. pictaafterPandorasp. nov. infection. The results from infection bioassays were discussed in relation toPandorasp. nov. host range and its suitability as biocontrol agent in integrated pest management strategies of psyllid pests, including vector species, in orchards.
