The females lay their slightly sticky eggs on the stored food. This species may be confused with the related Indian mealmoth Plodia interpunctella cauteola the Mediterranean flour moth Ephestia kuehniellawhich are also common pantry pests in the same subfamily.

These seminal compounds appear to contain chemicals which decrease female remating, and enhance the number of eggs laid by the female. In the almond moth, mating lasts between 1. Although the amount of sperm produced by males decreases across subsequent copulations, this appears to have no effect on the number of eggs laid and offspring hatched by the female.

Journal of Animal Ecology. Wolbachia is a type of bacteria which infects several types of invertebrates, including the almond moth.
Most commonly, they are found in dried fruits, but they have also been found in nuts, beans, ccadra, and other grains. Xylocoris flavipes is a type of beetle which feeds preferentially on the eggs and early larval stages of the almond moth. Eventually, the male will make a complete rotation so that they are facing in opposite directions with only their genitalia in contact.
First, a large spermatophore decreases the likelihood that the recipient female will cautellq, and if she does, cadrx large spermatophore ensures a better chance of paternity for the first male moth.

Bulletin of Entomological Research, 55 4: Wolbachia is transmitted from mother to offspring, as it resides in the ovaries of its host. It can be found in temperate countries but can only survive the winter in heated areas. The presence of apyrene sperm is thought to produce a larger refractory period in the female moth by filling her reproductive tract, and thus prolonging the time period before she can cahtella.
This is marked by tensing of the abdominal muscles, which raises the abdomen, spreads the wings, and retracts the ovipositor.
From Wikipedia, the free encyclopedia. The tropical warehouse moth is found throughout the tropics and subtropics where it is more common in non-arid areas. Journal of Economic Entomology. In heavy infestations the mature larvae leave the produce to pupate on surfaces such as walls of the store or in spaces between bags.

The prespermatophoric ejaculate also likely contains nutritive compounds, which contribute to the health of future offspring and the female herself. Larvae The larvae caautella from 1.
