Association of entomopathogenic fungi with exotic bark beetles in New Zealand pine plantations
Mycopathologia 169 (1), 75-80
Abstract: Hylastes ater and Hylurgus ligniperda are introduced pests of re-established Pinus radiata in New Zealand. Both species breed under the bark of stumps in recently harvested areas. Adult maturation feeding on pine seedlings planted in adjacent areas can significantly impact seedling growth, and in severe cases seedlings will die. Entomopathogenic fungi are important natural mortality factors in bark beetle populations, and Beauveria spp. are predominant. Here, we report on the isolation of other fungal species from H. ater in New Zealand. Based on morphological characteristics and sequencing data, two species, Metarhizium flavoviride var. pemphigi and Hirsutella guignardii, were recovered from H. ater. Both are new records for New Zealand and appear to be the first records of these species from bark beetles worldwide.
