Fruit Fly Hosts
Hannah Trow and her mother found a seed weevil living in a mango they bought from a store in Marton, Newzealand. The find raised biosecurity concerns, with Horticulture New Zealand chief executive Peter Silcock, claiming that “mangoes are a potential host for fruit flies.”
While the Ministry of Primary Industries in New Zealand has confirmed that more cases of foreign insect pests in imported mangoes since a 10-year-old girl's discovery have come to light, there is no cause for panic. According to the MIP, “the mango Hannah found the weevil in would have been irradiated by Australian authorities before entering the country. The finding of a different insect is not a reason to have concerns regarding fruit flies. After irradiation, adult weevils can survive but would be sterile."
Since ONE News aired the story, more complaints have surfaced. However, the Ministry claims it receives a “dozen calls” regarding Australian mango seed weevils each year and remains confident in the biosecurity measures in place for stopping fruit fly outbreaks.
