The male sex pheromone serves as a key species recognition signal. Infestations have been reported in cereals and chocolate manufacturing facilities. Journal of Applied Entomology. The almond moth thrives best in warm, humid environments. High temperatures were tested against egg, late larval instars and pupal stages of E.

Almond moth Caterpillar and moth Caterpillar below and pupa above in peanut husks Scientific classification Kingdom: The Tropical warehouse moth is often confused with the Indian meal moth Plodia interpunctella. This is marked by tensing of the abdominal muscles, which raises the abdomen, spreads the wings, and retracts the ovipositor.
As such, Wolbachia does not directly kill the infected moth which houses it, because its primary means of spreading are through the moth’s reproduction.
The larvae of tropical warehouse moths commonly attack grains, nuts, dried fruits and a great acutella of other stored products. Adult of the tropical warehouse moth, Cadra cautella.
Margraf Publishers Scientific books, German. In other projects Wikimedia Commons Wikispecies. Eggs The eggs are translucent yellow with a sculptured surface. Trichogramma are very small waspsand they will puncture the eggs of almond moths and leave their own progeny ephestis. An admixture of approved grain insecticides, especially organophosphorus compounds, will protect against this pest. The fphestia caterpillars feed externally on maize grains but also cause damage to stored products through contamination with the silk webbing it produces and faecal pellets, cast skins and egg shells.
Eventually, the male will make a complete rotation so that they are facing in opposite directions with only their genitalia in contact. The act of feeding can be extremely damaging to the food produce and there is often further cautellaa of food stuffs with faecal matter.

The almond moth often takes part in courtship with other species, especially with the Indian mealmoth Plodia interpunctella. 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 Pest Science The purpose of the study was to verify the efficacy of a mating-disruption system MD applied in a confectionary factory infested by almond moths, Ephestia cautella Walkerusing pheromone traps and caurella presence of spermatophores in females caught with water traps. Zeitschrift des Wiener Entomologen-Vereins Talwana, Makerere University; John R.
Several parasites of the genus Trichogrammaincluding T. Fronting-up involves the male positioning himself first in front of the female and rapidly flapping his wings, which contain many scent scales.

Freezing and Heating Where the infrastructure exists, freezing for several days and heating for 24 hours have proved to epyestia effective control methods for stored product pests.
