Fruit fly control methods, fruit fly trapping, garden cleaning and biological control to reduce the harm.

As the temperature rises in summer, oriental fruit flies are also ready to move, not only the people's favorite mango, guava is easy to suffer, often used for warm jujube, but also the favorite food for fruit fly larvae. The agricultural improvement farm in Miaoli District reminded that unlike ordinary fruits, red jujube can be bagged to avoid insect pests, so control measures should be carried out during the flowering period of red jujube trees in mid-April: fruit fly trapping, fruit drop and biological control, and reducing the number of fruit fly groups. in order to reduce the harm of jujube fruiting period.

Lu Meijun, director of the biological control branch of the Miao change field, said that the oriental fruit fly will lay eggs in the fruit, causing fruit drop and fruit decay. The fruit fly larvae living in the red jujube will jump from the fallen fruit into the soil to pupate after ripening, and continue to reproduce after breaking the pupae. Farmers are advised to avoid throwing the fruit into the garden. Fruit fly migration and fecundity is strong, the implementation of garden management is not only the responsibility of a single farmer, regional control can reduce the harm of fruit fly.

In addition to the garden management of falling fruit, Miao Chestnut Farm points out that farmers can hang yellow armyworm boards, spray sticky insect glue, hang long-term trapping boxes of methyl clove oil and protein yeast ingots and other trapping materials to reduce the number of adults. In addition, the biological control field of Miaoli Farm also mastered the cultivation technology of Oriental fruit fly natural enemy "format wide wasp". The format wide wasp can parasitize on the pupa of Oriental fruit fly, prevent fruit fly from becoming pupa, and reduce the number of adults through biological control. However, Lu Meijun said that at present, because the cultivation technology of "format wide wasps" has not yet been changed, and the number of wasps in the control field is limited, it is suggested that farmers should first easily obtain materials and start with the management of the park.
