Growth And Reproduction

AbstractThe addition of copper to an artificial diet greatly improves growth of the house cricket, Acheta domesticus (L.). Adding zinc improves growth in the presence of added copper, but not in its absence, indicating an interaction between the two trace elements. Reproduction is always ’normal’ with added copper in the diet. Zinc added at a low level will support ’normal’ reproduction, but not at high levels. Survival is poor without added copper in the diet. It is suggested that the minimum growth requirements for zinc and copper are a total of 23 μg/g diet and 14 μg/g diet respectively.

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.

Growth And Survival

AbstractThe addition of copper to an artificial diet improves growth and survival of the house cricket, Acheta domesticus (L.), the optimum concentrations being 2 μg/g for females and 10 μg/g for males. This sex difference in requirements is attributed in part to the accumulation of copper by the larval testis. Adult males showing a loss in pigmentation, the so-called ’albino’ males, are obtained on diets low in copper; the percentage of ’albino’ males is increased by the addition of vitamin E to the diet. The pigmentation effect of vitamin E is explained by movement of copper into the testis, the development of which is stimulated by vitamin E.

AbstractAddition of DL-α-tocopherol (vitamin E) at a level of 17.2 μg/g to an artificial diet containing casein, glucose, cellulose powder, salts, cholesterol, and a mixture of B-vitamins results in a loss of pigmentation in 30–50% of males on adult emergence. These albino males are of a light amber colour, apparently lacking melanin, although their cuticle appears to be sclerotized, and their sexual behaviour is normal.

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.
