GRDC Code: DAW2212-001RTX
NGN: Furthering grower knowledge and understanding of the scientifically unidentified 'Dongara weevil'
Since 2013, an unidentified weevil has been reported by growers and advisers to be repeatedly causing damage to canola and coriander crops in localised areas of Mingenew and Dongara in Western Australia (WA). Anecdotally, the damage appears to be worse on heavier soils compared to lighter soils and the species is difficult to kill with insecticides at rates that are deemed effective for other weevil species. This investment aims to (1) expand the understanding of its distribution in WA, (2) determine some of the factors that influence the incidence and severity of crop damage caused by this species, and (3) identify or describe the 'Dongara weevil'. This information will be pivotal to better inform possible future initiatives of managing this unidentified crop pest.
