Fruit fly affects crops seriously. Fruit fly adults generally are acting actively during the day, especially from 1pm to 4 pm in the afternoon, and stop actions after dark falls. Fruit fly adults usually are active at temperature between 21~30°C and acting more actively on sunny days than cloudy days, and barely acting in rainy days. In case of high temperature, they often find shelter in the shade, such as the shady side of leaves. Spawning begins in mid-April and it is a most serve period from May to August.
Fruit fly adults use the ovipositor to penetrate skin of fruits to spawn eggs. After the larva hatching, the fruit fly larvae drill into fruits to feed. Then damaged fruits turn yellow, stinky and rotting. What’s worse, maggots creep inside, causing fruit falling.
