Acronym: CCA. Sometimes referred to as warehouse moth or tropical warehouse moth; scientific references may use Ephestia cautella. The reduction in mating of Ephestia cautella caused by permeation of the atmosphere with synthetic sex pheromone components was investigated in the. Adults of Ephestia cautella (Wlk.) were exposed to pressures of , , , and mm Hg at 26 ± 1 °C and 70 ± 5% r.h., in a specially designed.

Factsheet – Cadra cautella Walker, – Tropical Warehouse Moth

Adult emergence from the cocoon usually occurs during the late afternoon. Adults avoid strong light cautellla rest in dark places with wings ephesgia over the dphestia. Sticky traps baited with a sex pheromone can be used to monitor adults. Webbing of grains produces lumps as in the case of Corcyra. While instances of remating are low in almond moths, it is most likely to occur in instances where the female received only seminal compounds and no spermatophore.

As almond moths exists primarily as a pestits habitat is often some kind of dry food product which is stored in a warehouse or similar industrial environment. Freezing and Heating Where the infrastructure exists, freezing for several days and heating for 24 hours have proved to be effective control methods for stored product pests.

Almond moth

When pupation draws near, they generally migrate away from the foodstuff, and climb walls in search of crevices to pupate safely away from the food source. The larvae of tropical warehouse moths commonly attack grains, nuts, dried ephestiq and a great variety of other stored products. Exposure of pupae to minutes or more is effective to get a complete mortality for the pupal stage. Journal of Stored Products Research.


Ephestia CautellaWarehouse Almond Moth. 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 remate.

Controlled atmosphere Where suitable infrastructure exists, low oxygen and carbon dioxide-enriched atmospheres can be used to control stored product pests. The wing span is mm and both fore- and hind-wings have broadly rounded tips and short fringes of hairs.

The severity of a tropical warehouse moth infestation can be reduced by good store hygiene which includes cleaning the store between harvests, immersing grain sacks in boiling water and fumigating the store to cxutella residual infestations, ensuring that all spillages are removed, all cracks and crevices in the store are filled and the selection of only uninfested material for storage.

This is marked by tensing of the abdominal muscles, which raises the abdomen, spreads the wings, and retracts the ovipositor. High temperatures were tested against egg, late larval instars and pupal stages of E. Larva of the tropical warehouse moth, Cadra cautella. The tropical warehouse moth feeds on a range of stored foods, notably cereals and cereal products.

Other common names, particularly in nonbiological literature, are dried currant moth and fig moth, which invite confusion with the close relatives Cadra figulilella raisin moth and Cadra calidella dried fruit moth. This, in addition to other mechanical barriers to insemination, make copulation rare. Talwana, Makerere University; John R. Margraf Publishers Scientific books, German. Eigenartige Geschmacksrichtungen bei Kleinschmetterlingsraupen [“Strange tastes among micromoth caterpillars”].

Only moths who live to adulthood will be able to reproduce and thus spread the bacteria further. Like the raisin moth, the almond moth has achieved an essentially cosmopolitan distribution due to inadvertent transport with food products in its larval form. Thus, the exploration of natural enemies of the almond moth including various kinds of predators and parasites has been pursued as a means to control infestations.


Ascidaein relation to the natural control of Ephestia Cautella Walker Lepidoptera: Adults The adult forewings are greyish-brown with scattered darker patches. Adult females lay around eggs during the first week, usually starting days after adult emergence. The back edges of the wings are lined with a short fringe. The larvae caterpillars feed externally on maize epheshia but also cause damage to stored products through contamination with the silk e;hestia it produces and faecal pellets, cast skins and egg shells.

Almond moth – Wikipedia

The female will either ephestla an acceptance posture, which essentially means that she remains immobile, or a rejection posture, which can involve movement away from the male or flapping of wings.

Journal of Animal Ecology. Stored Products Management, 2nd Ed. Behavioral Ecology and Sociobiology. Braconidae and Venturia canescens Hymenoptera: First, a large spermatophore decreases the likelihood that the recipient female will remate, and if she does, a large spermatophore ensures a better chance of paternity for the first male moth.

The adult tropical warehouse moth is commonly ephesia with the Indian meal moth, Plodia interpunctella but can be differentiated from it by the distinct colouring of the forewings of Indian meal moth a dark band separating the two differently coloured halves of the forewing. M and Inscoe, M. Two faint dark oblique lines bordered with a whitish suffusion lay across the fore wings.

Cosmopolitan in the eohestia and warmer temperate areas of the world. Forewings are grey-brown and banded with lighter and darker colours.
