Development of high level resistance to phosphine fumigant in flat grain beetles (Cryptolestes ferrugineus) in large bulk storages in Australia poses a serious threat to the biosecurity of Australian grain. The level of resistance in this species is the highest ever detected in any stored grain insect pest in Australia with a resistance factor of 875. Laboratory studies showed that at 0.5 mg/L and at 1 mg/L of phosphine 30 and 24 days are required, respectively, to attain population extinction. These doses are currently being tested in field trials for their validation. Moreover, we have developed an action plan in collaboration with project scientists and the major Australian bulk handling companies aimed at eradicating infestations of phosphine resistant flat grain beetles and preventing their spread. The key components of this plan include the use of grain protectants and sulfuryl fluoride to eliminate phosphineresistant populations, adoption of an intensive hygiene program and monitoring of insect populations through inspection, sampling and resistance testing. |
