Its habitat is some kind of dry food product, which is stored in warehouses or similar industrial environments, in dried fruit, they are commonly found, but they have also been found in nuts, beans, flour, and other grains.

Food source:

Almond moth larvae also hatched onto a variety of dry foods and products, which they use as their primary food source, although several different kinds of dried fruit and other dried products are being infested by moths, the ideal food for larvae development is cracked and ground seed, then whole seed and grain. Larva also feed on eggs and other smaller larvae, so they called them cannibalistic. Adult almond moths don’t eat during their short life span; they even drink water if they have access to it.

Life cycle

In warm and humid environments, it thrives best .30-32-degree Celsius temperature range is ideal for almond moth development. 70=80% relative humidity is ideal, eggs hatch in half to three days if the condition is optimum, 17-37 days are required for the larval developmental period ranging from five instars; if temperature and humidity are optimal, then pupation takes place in 7 days, Adult almond moths, male and female, live an average of 6-7 days and 10 days respectively.

Biological control:

There are some predators of the almond moth, Xylocoris flavipes, which is also called true because it feeds on the eggs and early larval stages of the almond moth, some mites, Blattiscocius tarsalis, also feed on the almond’s eggs throughout its life cycle, it will be considering the mechanisms of controlling infestation of almond moth.

Parasites:

Parasites of the almond moth also belong to the Hymenoptera, and several parasites of the genus Trichogramma, including. Evanescens, T. cacoeciae, Trichogramma are very small wasps; they will puncture the eggs of the almond moth, leave their own progeny inside eggs, Inside the egg, the actual larvae will be killed. Other kinds of wasps are produced from the eggs of the moth, which are called bracon hebetor, and Venturia canescens parasitize almond larvae in the later instar.

Diseases:

Several types of invertebrates, including the almond moth, which is infected by some bacteria, Wolbachia, it is transmitted from mother to offspring, as it resides in the ovaries of its host. The almond moth is not directly killed by these bacteria; the moths who are in their adult stages can reproduce and spread the bacteria further.

Chemical:

synthetic pyrethroid insecticide. Pyrid Aerosol is used as a flushing agent, to treat tight cracks and crevices where moths or other pantry pests may be hiding, in small spaces, almond moths tend to hide and lay their eggs, by applying these, we can control and kill them with contact.
