Scientific Name: Mudaria luteileprosa Holloway
The mature durian seed borer lays eggs on the fruit near the calyx. When the fruit is 6-week old until the harvest period, it pierces through to eat the seed and excretes to dirty the flesh. The worm lives in the fruit until the fruit is mature. When the worm is mature, it will pierce through the peel to stay in the silk case underground. Most of the destroyed durian fruit are in the phase that the seed is robust.
