Abstract We used the following new range of insect species as baits for trapping entomopathogenic fungi: Plodia interpunctella, Rhyzopertha dominica, Tribolium confusum, Trogoderma granarium, Ephestia kuehniella and Tenebrio molitor, which constitute important stored product pests. Soil samples were collected from random points in olive tree orchards in Western Greece using Geographical Information Systems (GIS) and sample point coordinates were located with the Global Positioning System (GPS). Entomopathogenic fungi were identified by sequencing the ITS4 and ITS5 regions of the genomic DNA. Among the isolated fungal species, Beauveria bassiana and Metarhizium anisopliae showed the highest frequency, at 33.8% and 25.4% respectively. They also caused the most infestations of R. dominica and T. confusum whose mortality reached 33–97% and 87–100% respectively. We have also isolated various other fungal taxa such as Aspergillus alliaceus, Aspergillus insuetus, Aspergillus sp., Apophysomyces ossiformis, Chaetomium acropullum, Chaetomium sp., Chaetomium globosum, Chaetomium truncatulum, Trichoderma gamsii and Purpureocillium lilacinum. Our study confirms that T. confusum and R. dominica may be further utilized as baits for entomopathogenic fungi.

储藏产品害虫作为捕获希腊西部橄榄树果园昆虫病原真菌的模型

摘要 我们使用以下新的昆虫种类作为诱饵诱捕昆虫病原真菌:间点螟、多米尼卡丝虫、三叶草、谷斑蝽、绦虫和黄粉虫,它们是重要的贮藏害虫。 摘要 我们使用了以下新的昆虫种类作为诱饵来诱捕昆虫病原真菌:Plodia interpunctella、Rhyzopertha dominica、Tribolium confusum、Trogoderma granarium、Ephestia kuehniella 和黄粉虱。使用地理信息系统 (GIS) 从希腊西部橄榄树园的随机点收集土壤样本,并使用全球定位系统 (GPS) 定位样本点坐标。通过对基因组 DNA 的 ITS4 和 ITS5 区域进行测序来鉴定昆虫病原真菌。在分离的真菌物种中,白僵菌和绿僵菌的出现频率最高,分别为 33.8% 和 25.4%。它们还导致 R. dominica 和 T. confusum 的死亡率分别达到 33-97% 和 87-100%。我们还分离了各种其他真菌类群,例如 Aspergillus alliaceus、Aspergillus insuetus、Aspergillus sp.、Apophysomyces ossiformis、Chaetomium acropullum、Chaetomium sp.、Chaetomium globosum、Chaetomium truncatulum、Trichoderma gamsii 和 Pureopureolum。我们的研究证实,T. confusum 和 R. dominica 可进一步用作昆虫病原真菌的诱饵。
