Parasitoids of Agrilus spp. in Europe: Anticipating the arrival of Agrilus planipennis

Biological Control
The emerald ash borer (EAB), Agrilus planipennis, is a woodboring beetle native to East Asia. It is highly invasive in North America, where it causes large-scale dieback of American ash species, Fraxinus spp. EAB is also invasive in Western Russia and Ukraine, and it continues to spread towards Central and Western Europe where all three native ash species are susceptible. Biological control approaches offer sustainable solutions to control invasive pests. In North America, four Asian parasitoid species that have coevolved with EAB have been introduced to control the pest. In Europe, many species of the genus Agrilus occur, and it is likely that at least some of their parasitoids will adopt EAB as a host as it spreads across the continent. However, parasitoids of Agrilus spp., are very poorly known in Europe because of the difficulty of studying the parasitoid complex of these solitary wood boring insects. In this review, we provide a literature overview of studies and records of European parasitoids of Agrilus spp. to provide a basis for future studies on the emerging parasitoid complex of EAB in Europe. Parasitoid records were found for 24 European species of Agrilus. Sixty-four parasitoid species were recorded, mostly larval parasitoids. However, it is likely that several of them are erroneous host-parasitoid associations or misidentifications, and the biology of most species and their role in the population dynamics of their hosts has been poorly studied. It is recommended to conduct pre-emptive studies on these parasitoids and their suitability as potential biological control organisms with EAB.
Co-formulation of Beauveria bassiana with natural substances to control pollen beetles – Synergy between fungal spores and colza oil
Kaiser, Deborah; Handschin, Stephan; Rohr, Rudolf P.; et al. (2020)
Biological Control
Pollen beetles (Brassicogethes spp.) are a major pest in colza (Brassica napus L., also known as oilseed rape) and show increasing resistance to commonly used insecticides. Entomopathogenic fungi (EPF) such as Beauveria bassiana have potential as a sustainable alternative means of control. However, field applications of fungal spores targeting the immigrated beetles on the crop have not been efficient to date. To enhance the effectiveness of fungal spores in insect pest control, this study focused on co-formulations of B. bassiana blastospores with vegetable oil and stone dust, which have already shown effects against pollen beetles as single treatments in previous studies. To estimate synergistic effects of these combinations, we developed a novel statistical approach based on a generalized linear mixed effect model and a parametric bootstrapping method. The combination of B. bassiana and colza oil increased pollen beetle mortality much more than expected from the additive effect of single applications, indicating a strong synergistic effect. In contrast, the combination of B. bassiana and stone dust showed an antagonistic effect, i.e. mortality was lower than expected from the additive effect of single substances. Our study confirms the suitability of a combination of entomopathogenic fungi with vegetable oil and demonstrates that combinations may exhibit a higher level of pest control than expected from single substances.
