AB Fusarium spp., as well as other endophytic or pathogenic fungi that form communities, havebeen reported to be phoretically associated with bark beetles (Coleoptera; Scolytinae) worldwide.This applies to Fusarium circinatum Nirenberg and O’Donnell, the causal agent of pine pitch canker(PPC), which threatens Pinus radiata D. Don plantations in northern Spain. The main objective ofthis study was to study the fungal communities associated with bark beetles and their galleries instands affected by PPC, with special attention given to Fusarium species. Funnel traps and logs wereplaced in a P. radiata plot known to be affected by F. circinatum. The traps were baited with differentattractants: four with (E)-pityol and six with ethanol and α-Pinene. In addition, fresh green shootswith Tomicus piniperda L. feeding galleries were collected from the ground in 25 P. radiata plots affectedby PPC. Extracts of whole insects and gallery tissues were plated on agar medium to isolate andidentify the associated fungi. A total of 24 different fungal species were isolated from the bark beetlegalleries constructed in logs and shoots, while 18 were isolated from the insect exoskeletons. Tendifferent Fusarium species were isolated from tissue and insects. Fusarium circinatum was isolatedfrom bark beetle exoskeletons (1.05% of the Pityophthorus pubescens Marsham specimens harbouredF. circinatum) and from the galleries (3.5% of the T. piniperda feeding galleries harboured the pathogen).The findings provide information about the fungal communities associated with bark beetles inP. radiata stands in northern Spain.
