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.

Full grown larva is 20 mm long, greyish-white, with sparse hair-like setae on the body. Larvae are able to chew through foil wrapping to infest protected products.
In an integrated pest management programme, the combined use of MD and water traps eliminates large numbers of male and female almond moths. The almond moth thrives best in warm, humid environments.
Larval growth and rate of development depends on temperature. The almond moth or tropical warehouse moth Cadra cautella is a small, stored-product pest. They fly actively in the mornings and evenings to lay eggs within days after emergence.
Phycitini Household pest insects Cosmopolitan moths Moths described in Although it thrives best in tropical climatesit has spread to many regions around the globe due to its tendency to infest dry goods that are shipped internationally.
A variety of species within the order Hymenoptera are parasites of the almond moth. Only moths who live to adulthood will be able to reproduce and thus spread the bacteria further. The wing span is mm and both fore- and hind-wings have broadly rounded tips and short fringes of hairs.
While instances of remating are low in almond moths, it is most likely to occur in instances where the cautlela received only seminal compounds and no spermatophore.
Ephestia Cautella, Warehouse Almond Moth – Russell IPM – SPI
This pest attacks a variety of stored products that include rice, wheat, maize, beans, cotton seeds and cotton cake, flour, bran, oat ephetsia and maize-meal, dry fruits such as fig, almond, raisins, dates, pears, ground nuts, walnuts etc.
These seminal compounds appear to contain chemicals which decrease female remating, and enhance the number of eggs laid by the female. Sticky cauteella baited with a sex pheromone can be used to monitor adults. Previous tab Next tab.
Xylocoris flavipes is a type of beetle which feeds preferentially on the eggs and early larval stages of the almond cautellx. In the almond moth, mating lasts between 1.
Mortality tended to be increased with the increasing of temperature and exposure time. Adult almond moths do not eat during their short lifespan but will drink water if they have access to it. Results obtained confirmed that water is a considerable attractant for E.

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. When pupation draws near, they generally migrate epnestia from the foodstuff, and climb walls in search of crevices to pupate safely away from the food source.
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 confused with the Indian meal moth, Plodia interpunctella but ehpestia be differentiated from it by the distinct colouring of the forewings of Indian meal moth a dark band separating the two cautell coloured halves of the forewing.
Braconidae and Cautellla pretiosum Hymenoptera: Before pupation, the last instar larva builds a cocoon. Views Read Edit View history. An admixture of approved grain insecticides, especially organophosphorus compounds, will protect against this pest. This is marked by tensing of the abdominal muscles, which raises the abdomen, spreads the wings, and retracts the ovipositor. Fumigation of grain stocks with phosphine will control existing infestations but will not protect against re-infestation.
Bulletin of Entomological Research, 55 4: Retrieved from ” https: Like the raisin moth, the almond moth has achieved an essentially cosmopolitan distribution due to inadvertent transport with food products in its larval form.
Adults The adult forewings are greyish-brown with scattered darker patches.
