Title: My VistaPrint Electronic Business Card

The incubation period for the eggs is about one week. The young larvae bore to the center of the fruit, where they feed until reaching maturity. Many infested fruits drop to the ground in June. After about 16 days in the larval stage, the full-grown larvae leave the fruit, enter the soil to a depth of about 1 inch, construct pupal cells and pupate. The length of time between larval entrance into the soil and the emergence of the new adult is about 30 days. The complete cycle from egg to adult takes about 50 to 55 days. After the adults emerge from the soil in late summer, they will feed on maturing apples until cold weather forces them into hibernation quarters. Hope this helps!

Hi

Does any one know how long the PC larvae are in the fruit that drop on the ground? Just Curiosity.

thanks
