“…Chan et al (2000) analyzed the amount of protein, amino acids, fat, minerals, and carbohydrates in fresh diet, spent diet and in fruit fly larvae reared on this diet. Also the meridic diet of Chang et al (2000) (with at least one unknown chemical structure) was based on Tanaka's diet.

Five larval diets for laboratory rearing of Ceratitis capitata were tested. These diets were based on wheat bran, microcellulose, potato starch and agar. To evaluate the quality of diet, pupal rearing efficacy and pupal weight were checked. The best results were obtained with an agar based diet used for Manduca sexta laboratory rearing. To simplify the preparation and to reduce the cost of this diet, a new formulation was developed. Larvae reared on the new agar-based diet achieved higher pupal rearing efficacy than larvae reared on bran diet recently used in medfly mass rearing facilities. Heat treated medflies reared on the new agar-based diet achieved similar pupal rearing efficacy with heat treated medflies reared on bran diet. When testing population density, higher pupal rearing efficacy was again achieved on new diet. The highest pupal rearing efficacy was achieved with 100 eggs per 25 g of diet, lowest with 500 eggs per 25 g of diet. Concerning pupal weight, there was no difference in results achieved on Petri dishes with different larval population densities. Larvae reared on new agar-based diet reached better results than larvae reared on bran diet. The preparation of the new diet is simple and the cost is low, so it is good for laboratory tests and rearing.

“…The essential amount of this vitamin for first and second instar larvae in the artificial diet is 0⋅008 g per 100 g of artificial diet. Chang et al (2000) in the study of the factors affecting the growth of Ceratitis capitata, found that it is essential for growth, in small quantities. Therefore, the silkworm's requirement (and also the need of most insects) for this vitamin is very limited and high doses of this vitamin can leave many negative effects.…”

A high-dose of vitamin B 3 in silkworm diet interrupts larval feeding and normal growth. High mortality of larvae occurs during molting and they cannot complete this process normally. Also the larvae exhibit nicotinamide hypervitaminosis symptoms such as immobility, dyspepsia, darkening of the skin, inability to excrete normally, exerting brownish fluid from anus and swelling of rectal muscles. Maximum larval weights in 1, 2 and 3 g/l treatments were 2⋅9, 1⋅6 and 1⋅2 g respectively, while maximum larval weight in the control was 5⋅6 g. Larval stage compared to control had increased 18, 26 and 31 days respectively. The concentration increase of uric acid in haemolymph demonstrates the hyperuricemia, while other measured biochemical compounds show significant decrease; sodium and potassium did not change significantly.[Etebari K and Matindoost L 2004 Effects of hypervitaminosis of vitamin B3 on silkworm biology; J.

“…These types of diets for larvae fruit flies seldom have been developed (Tsitsipis, 1989). Recently, Chang et al (2000) reported on the development of a meridic larval diet for the Medfly, in which all of the ingredients but one are chemically characterized. The new diet is based on corncob as a bulking agent that, despite some trace nutrient elements, is basically a nutritionally inert substance (Chang et al, 2001).…”

The effects of sucrose and amino acid (aa) composition and concentration in meridic larval diets (e.g., partially defined at the chemical level) was examined on several parameters of Mediterranean fruit fly (Medfly) development. Lipid and protein levels of pupating larvae and emerging adults were examined. Different sucrose concentrations in the diet had small effects upon most of the development parameters. However, sucrose concentration significantly affected the ability of larvae to accumulate lipid reserves and proteins. Adults emerging from the different sucrose diets did not significantly differ in their lipid contents and protein loads. Specific deletions of aa from the diet, and general aa concentration, had a strong effect upon the parameters of development and pupating larvae lipids and proteins. Glycine-deletion was the most deleterious, followed by the deletion of all non-essential aa, and serine. High aa concentration in the diet has a detrimental effect upon development. Lipid contents in pupating larvae, and to some extent protein levels, were affected by aa manipulations in the diet. Lipid and protein loads in emerging adults were not significantly affected by aa manipulations. Based on the analysis of lipid frequency distribution it is suggested that the Medfly seems to regulate the level of lipid content in emerging adults within a certain range, regardless of the larval diet history or lipid contents. Proteins do not seem to be regulated as are lipids. These results point to an interesting and unexpected metabolic regulation of energetic resources during metamorphosis of the Medfly.
