It covers a range that includes much of the world, primarily situating itself in areas of California, Florida, the Eastern Mediterranean region, and some parts of Africa, Australia, and South America.
[1][2] The moth prefers to live in a hot, arid climate with little moisture and plentiful harvest for its larvae to feed on.
[3] Study of this species is important due to the vast amount of economic damage it causes yearly and worldwide to agriculture crops.
Copulation consists of specific head bump technique paired with thrusting behavior.
During the start of cold winter months, the larvae of the raisin moth will move from the fruit in which they are enveloped to the top 4 inches of topsoil.
Its population quickly increased and spread throughout the world, now claiming ubiquity in the Eastern Mediterranean region, California, Florida, and some parts of Australia, South America, and Africa.
[2] Specifically, the moth is present in regions of optimal breeding temperature and food resources.
The raisin moth prefers a climate that has arid, hot, clear, and rainless summers, along with mild winters.
In particular they feed on fallen figs, ripe carob pods, grapes, cottonseed cake, cacao beans, prunes, peaches, apricots, pears, and more.
[3] The female raisin moth lays her fertilized eggs directly on or near the surface of the fruit of the host plant.
Several hymenopteran parasitoids such as Venturia canescens and Habrobracon hebetor harm raisin moth larvae.
Specifically, Habrobracon hebetor stings and in effect parasitizes raisin moth larvae during warm winter days when they are located under tree bark.
However, this parasitoid will not affect them during warmer seasons or on host plant fruit, so it is not effective as a natural pesticide.
[2] These pheromones are quite similar to those from other moths in the Phycitinae subfamily, so elaborate courtship rituals are performed to avoid interspecies mating.
[2] Male moths also release a species specific pheromone that serves to reduce interspecies mating.
Females exhibit a post-copulatory behavior that involves performance of a drag walk with the male moth.
As the larvae feed on the insides of the fruit, it becomes filled with their excrement and fine powdery residue that is produced from the boring process.
Mating disruption through the use of synthetic pheromone mimics is also an effective strategy and a greener alternative to pesticides.
A specific pheromone, (Z,E)-9,12-tetradecadienyl acetate, also known as TDA or ZETA, belongs to many species of pyralid moths and is a male attractant.
