Answer: What you describe might indicate presence of the fig wasp or it could be normal and natural. Sometimes the fruit fail to mature. This may not be due to disease but rather to natural conditions such as the type of plant and the kind of flower it produces. Figs may bloom several times a year; the fruit that develops from early blossoms may be injured by spring frosts while the fruit from late blossoms may not have sufficient time to mature. Fruit may also drop from plants stressed by nematodes or environmental conditions such as dry weather.
As for the fig wasp, the female enters the undeveloped fruit, lays her eggs and then dies. The eggs hatch and then exit the fruit. Look carefully at the fruit for entrance or exit holes.
