Oriental fruit moth overwinter as larvae in silken cocoons on the tree or in the duff on the orchard floor.

In the spring the larvae become pupa, and begin to emerge as adults during April, shortly The Oriental fruit moth in California book peach trees bloom. Time from egg laying to hatch can take anywhere from 5 to 21 days depending on the temperature.

Oriental fruit moths have four to five generations per year in Pennsylvania, with the first and last two generations most numerous.

They overwinter as larvae in silken cocoons on the tree or on the ground, and they pupate and begin to emerge as adults during April, shortly before peach trees bloom.

These females lay up to eggs, primarily. The Oriental fruit moth is a small moth, just about a quarter of an inch long. It’s gray, nondescript, and mostly flies at night between dusk and dawn, so you’re unlikely to run into them in the garden.

The adults find host trees to lay eggs. The eggs then turn into larva, which can feed on the tips of fruit. Oriental fruit moth larvae possess a small, dark, comb-like structure called an “anal comb” which can be seen using a good quality hand lens or, if the larvae are very small, using a microscope.

Adult oriental fruit moth are small (about mm), greyish-brown moths with silvery scales on their wings. The underside of forewings is light. Oriental fruit moth can infest pears, peaches, nectarines, apricots, plums and apples.

There are three generations of oriental fruit moth in Ontario. A partial fourth generation may develop in some years, with adult flight and egg-laying activity extended into October. Eggs from this generation hatch and larvae move into fruit prior to harvest.

The oriental fruit moth (Grapholita molesta) is the No. 1 peach crop pest. Peach trees (Prunus persica) grow in U.S. Department of Agriculture plant hardiness zones 5 through 9. The small, grayish. The adult oriental fruit fly is somewhat larger than a housefly, about 8 mm in length.

The body color is variable but generally bright yellow with a dark T shaped marking on the abdomen. The wings are clear. The female has a pointed slender ovipositor to deposit eggs under the skin of host fruit.

Eggs are minute cylinders laid in batches. D.E. Sonenshine, in Reference Module in Life Sciences, Other successes and some limitations.

Affected areas heal leaving a small scar. Oriental Fruit Moth. Scientific name: Grapholita molesta Phenology models predict timing of events in an organism's development.

For many organisms which cannot internally regulate their own temperature, development is dependent on temperatures to which they are exposed in the environment.
