The event also educated farmers on methods to prevent the spread of the black-headed coconut maggot, which now has infested 5,597 rai of crops in Chonburi. In January, officials said maggots had hit 1,800 rai in Pong and Nong Plalai sub-districts.

Growers were shown how to cut and burn leaves, correctly use pesticides and release the braconid wasps, which feed on the bugs.

Wasps are being grown in a project run jointly by the Chonburi Provincial Agriculture Office, 14th Military Circle, Rajamangala University of Technology Tawan-ok, Chon­buri Plant Protection Center and community-based pest management centers.

Samar Chuenwongsa, director of the Chonburi Agriculture Office, said wasp releases were planned for the next four weeks.
