Cadra calidella

[5][6][7][8] The moth mostly presides in Mediterranean countries, although it can be found in other parts of Europe due to the transport of the carobs and dried fruits on which it feeds.

It can also be found in Central Asia, Kazakhstan, Transcaucasia, Caucasus, and the western part of Russia.

[9] The larva will enter diapause when temperatures have dropped below 24°, and will spend the winter months in hibernation.

[11] As part of this problem, the moths have been imported to other European countries such as Britain in fruit storage crates.

[13] Their feeding period lasts for 20 to 21 days,[10] during which the young larvae will tunnel into the food, lining the feeding-tunnels with thick layers of silk.

[14] Adult Cadra calidella lay their eggs on the surface of the dried fruit or carob before harvest.

In laboratory experiments, the larva will wander several centimeters above the food layer before finding a satisfactory location to pupate.

Once the last instar larva begins to diapause, it will spin itself a thin silk cocoon.

The moth will oftentimes be relocated from the Mediterranean countries to other areas in Europe through the transportation of carobs and dried fruits in the food industry.

Copulation would last from a range of a few minutes to over 6 hours, after which oviposition would begin likewise during dark conditions.

[14] Female C. calidella will produce sex pheromones to attract male moths during mating and courtship.

In the calling position, the female will expose her pheromone gland, which is between the eighth and ninth segments of the abdomen.

Males may have thus increased their reproductive fitness by mating with virgins as cued by the females' pheromone concentrations.

[15] Overcrowding of C. calidella is of particular interest in studies due to the desire to limit the population sizes of the storage pests in order to minimize the damage accumulated by the moths.

However, there is an optimum population density of moths, such that the highest level of food consumption was determined to be 5 larva per culture.

[17] While there are limited resources on the predation of Cadra calidella, laboratory experiments will often encounter diseased moths due to parasitism by Bacillus thuringiensis (Berliner).

This parasitoid, along with pheromone traps, have been employed as tactics to control the reproduction of the moth due to its threat to the dried fruit industry.

[13] Cadra calidella is most commonly identified as a storage pest moth, primarily in Mediterranean countries where dried fruits and carobs is a larger industry.

Control programs, such as the integrated pest management (IPM) project was started by the Extension Service in Upper Galilee.

Research on Cadra calidella including changing temperature, photoperiods, humidity, gamma radiation, and parasitoids.

Previous chemical control methods have largely been substituted with other pest control methods such as insect-proof screens, localized application of pesticides depending on the timeline of the moth’s life cycle, sex pheromone traps, and usage of parasitoids.
