Reproductive Effect

Experiments were carried out to determine the active principle(s) in wheat-germ oil responsible for the reproductive effect exerted by this substance on the house cricket, Acheta domesticus L., and also to investigate the physiological effects of the substance(s). The active principle is vitamin E. It exerts an absolute effect on the last nymphal stadium of the male, but the female appears to be unaffected. Spermatogenic activity is disrupted in the absence of the vitamin, resulting in drastic reduction or a total absence of sperm cells in the testes. Withholding the vitamin from insects causes the preoviposition period to be lengthened and fewer eggs to be laid.

Growth And Reproduction

Lipid other than sterol improves the growth and development of nymphs of Acheta domesticus (L.), as shown by the effect of adding wheat germ oil and linoleic acid to the diet. Such lipid is also necessary for reproduction: the effect appears to be on the male, but may also be on the female.

THE FORMATION OF THE CUTICLE IN THE HOUSE CRICKET, ACHETA DOMESTICUS (L.), AND THE ROLE OF OENOCYTES

Phenolic Metabolism

The cuticle of the house cricket, Acheta domesticus (L.), is made up of three layers: an epicuticle, an exocuticle, and an endocuticle. The epicuticle is laid down first and the endocuticle only after ecdysis. The possible functions of oenocytes in the formation of the cuticle concern the secretion of substances necessary for the wax layer of the epicuticle, a contribution to polysaccharide material involved in chitin synthesis and a role in the phenolic metabolism before sclerotization.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).

By Products

As insect farming is becoming more popular in Europe and in the US, the use of food industry by-products in insects’ feed is drawing more attention. However, it is still unclear how to maximise the use of by-products in the feeds while meeting the nutritional requirements and maintaining profitable rearing yields with the current production technology. In this study, we conducted an experiment in Finnish small-scale cricket farming and laboratory conditions to determine whether five diet treatments, including by-product diets with barley mash and turnip rape, modify the overall fresh yield (kg), development time and feed conversion rate of the house crickets (Acheta domesticus). We discovered that the diets differed in the overall fresh cricket yield (kg) but not in the development time or the feed conversion rate of the crickets. The diets with a high proportion of by-product decreased the price of the feed but at the same time reduced the yield. Based on our results, complex by-product diets with the by-product proportion of 20-41% are the most suitable for house cricket rearing.
