Abstract

The ambrosia beetle Blandford (Coleoptera: Curculionidae: Scolytinae) has recently emerged as a pest in Chinese poplar plantations, causing significant economic losses through damage to host trees in association with its mutualistic fungus . This study evaluated the biocontrol potential of strain B-BB-1, strain B-SM-1, its metabolite prodigiosin, and two ectoparasitic mites, and . exhibited significant lethality toward adult female , reduced offspring production, and inhibited growth. and prodigiosin had certain lethal effects on larvae and inhibited the growth of . Both mites effectively parasitized beetle pupae and larvae, with no significant differences in efficacy between the two species. These agents demonstrate promise for the biological control of , offering insights for managing ambrosia beetle infestations.
