The Federal Agency for the Safety of the Food Chain (FASFC) has detected another oriental fruit fly in Belgium, as reported by the agency on Wednesday, with the insect found in a trap at the market of Sint-Jans-Molenbeek in Brussels.
The oriental fruit fly poses no threat to humans or animals but can destroy entire crops of fruits and vegetables. Since 2023, 11 such flies have been found in Belgium. To limit their spread, the FASFC monitors thirty high-risk locations every summer and inspects imported fruits and vegetables year-round. The fly can grow up to one centimetre long and resembles a common wasp.
The fruit fly is prevalent in warm countries in Africa and Asia. When found in Europe, it is often imported or brought back by travellers. FASFC advises holidaymakers against bringing back fruits or vegetables from abroad. However, due to cold winters, it is unlikely for oriental fruit flies to establish a population in Belgium.
Nevertheless, FASFC aims to remain vigilant. The larvae can consume the flesh of crops, rendering them unsuitable for consumption. To increase inspections, the agency launched a citizen science project in May, in collaboration with several partners. Citizens can help by setting traps to detect the oriental fruit fly, and farmers should also remain alert. If fruit and vegetable growers find the fly on their crops, they should immediately inform the FASFC.
