“…The compositions of proteins are a characteristic of the species and the patterns of total amino acids in body contents do not greatly vary according to the food consumed by the larvae. The differences could result from the variations of the composition of the free amino acid pool (Chen, 1985). These assessments are supported by our results showing patterns of relative amino acid content similar for newly emerged females fed as larvae on the two kinds of foods.…”

“…acids, often occurring in excess related to protein synthesis (Chen, 1985). This level reflects the metabolic state of the insect and, in this regard, further investigations on the hemolymph compartment will be required to better adjust amino acid supplies from artificial diet to ladybeetle needs for anabolism.…”

Biological and biochemical parameters of a flightless strain of Harmonia axyridis, fed on a pork liver-based artificial diet and on Ephestia kuehniella eggs as controls, were compared. The diet-grown larvae showed a significantly longer developmental time and a lower adult emergence rate compared to control larvae. The weights of the newly emerged adults were significantly higher for adults fed E. kuehniella eggs during their larval stages than fed the artificial diet. In contrast, larval food source had no effect on the duration of the pre-oviposition period or adult longevity. For adults fed on E. kuehniella eggs as larvae, a significantly longer pre-oviposition period, lower daily weight gain and fecundity were found for the diet-fed females compared to those fed on E. kuehniella eggs throughout the life span. The adult food source had no significant effect on longevity and fertility. Lower amino acid and fatty acid contents (in particular C16:1 and C18:3n-3) were found for the prepupae and newly emerged females obtained from diet-reared larvae compared to controls. Deficiencies in fatty acids C16:1 and C18:3n-3 were also observed in females obtained from E. kuehniella egg-reared larvae and fed on diet from adult emergence. The analyses of the foods showed deficiencies in artificial diet, especially for some amino and fatty acids. The results suggest a non-optimal composition of the artificial diet and some possibilities for its improvement. However, this polyphagous predator could be reared from first instar larvae to fully reproductive adults on a pork liver-based artificial diet.

“…These macromolecules are concerned with the regulation of all biochemical events in the organism (Harper et al 1993). Accumulation of proteins in haemolymph and fat body during last instar development has been established by Chen (1985). Apart from this, in silk gland, accumulation of protein is a well-established fact.…”

Ajuvenoid, R394 (Ethyl 9-cyclohexyl-3,7-dimefhyi-2,4-nonadienoate) was applied topically to 5" 1 instar silkworm, Bombyx mori L, larvae {Hybrid: ΚΑ χ NB4D2) at a dose of 0.039 nl/larva at 24, 48, 72 and 96 h, for silk yield improvement. Three major selected tissues viz., posterior silk gland (PSG), haemolymph and fat body were collected from fully-grown larvae and the total protein, total carbohydrate and total lipid contents were estimated following standard procedures. The result indicated that the content of these primary metabolites varied significantly in the selected tissues depending on the time of juvenoid application. The highest protein content was observed in the haemolymph and silk gland in the larvae treated at 72 h whereas the fat body protein content was lowest for the same treatment. The total carbohydrate was recorded lowest in the 72 h treated larvae as against the highest in the control both in haemolymph and fat body with no significant change in PSG. The total lipid content did not show any notable variation in the concentration on juvenoid administration except in the silk gland treated up to 72 h which showed a decline. The results indicate that the juvenoid induces tissue-specific responses in terms of turnover in primary metabolites which commensurates with the corresponding changes observed in the cocoon weight and cocoon shell weight.

“…Insect hemolymph contains very large amounts of free amino acids compared to body fluids of other animals, and probably constitutes a reservoir for protein synthesis (Chen, 1985). Changes in the patterns of hemolymph free amino acids are influenced by several factors, including diet composition (Mullins, 1985).…”

Improvement of an existing meat-based diet has been obtained for rearing the generalist predator Dicyphus tamaninii (Heteroptera: Miridae). The approach followed, different from the classical addition/deletion method, was performing biochemical analysis of adult carcasses in order to have information about the nutritional status of the predator. Comparison of total, free amino acids and lipid composition of meat-reared and conventionally reared females allowed detecting some nutritional deficiencies. A reformulated diet with new sources of proteins and lipids was tested again with the predator. Some biological parameters of bugs that were inferior in the initial meat diet when compared with those of the conventionally reared insects, such as nymphal development time and fresh weight, have been improved with the reformulated diet.
