Agriculture technology: The fruit fly of the Pacific
Agriculture technology. The fruit fly is the term used to describe small flies of the family Drosophilidae. This term also makes it possible to evoke a category of devastating and very dangerous flies belonging to the Tephritidae family. In this one, we find several species of the genus Bactrocera, of which one of the most common is Bactrocera xanthodes, better known under the name of “fruit fly of the Pacific”.
Agriculture technology: Characteristic of Fly
The adult fly is thin and translucent, with a brown-orange color. This insect likes urban and suburban environments where there are plenty of fruit trees . It is absent from forest areas. The Pacific fruit fly feeds on host plants on which they mate. She manages to bite them using her ovipositor, and lays her eggs shallow. After the females have laid their eggs, maggots emerge and grow in the decaying fruits. They then perform their pupation on the ground. This fly attacks at least 24 species including papaya , mandarin , avocado and breadfruit. It is also spreading on about 10 wild species. Adult flies are attracted by methyl eugenol, an aromatic organic compound found in many plants. They especially like hot weather.
Agriculture technology: Damage caused
It has been found that this fly infests 62% of the ripe fruit of the American Samoa breadfruit. The marks of infection are clearly visible through necrotic traces of the bites. This insect is very dangerous and threatens the productivity of fruits by lowering their quality. The result is a disruption in trade, which results in significant financial losses.
Agriculture technology: Fighting the Pacific fruit fly
Harvesting of ripe fruit should be done to limit the development of the pathogen. They must then be packaged and kept away from crops. By practicing the trapping technique, we can capture the adults. In this case, a mixture of methyl eugenol and insecticide is made. Everything must be placed in the fruit trees. This trap, in addition to limiting the proliferation of adults, also makes it possible to monitor the invasion of new areas. It is good to renew it every 3 months.
