Lipid and protein loads in pupating larvae and emerging adults as affected by the composition of Mediterranean fruit fly (Ceratitis capitata) meridic larval diets

摘要: The effects of sucrose and amino acid (aa) composition concentration in meridic larval diets (e.g., partially defined at the chemical level) was examined on several parameters Mediterranean fruit fly (Medfly) development. Lipid protein levels pupating larvae emerging adults were examined. Different concentrations diet had small upon most development parameters. However, significantly affected ability to accumulate lipid reserves proteins. Adults from different did not differ their contents loads. Specific deletions aa diet, general concentration, a strong effect lipids Glycine-deletion deleterious, followed by deletion all non-essential aa, serine. High has detrimental larvae, some extent levels, manipulations diet. loads manipulations. Based analysis frequency distribution it is suggested that Medfly seems regulate level content within certain range, regardless history or contents. Proteins do seem be regulated as are lipids. These results point an interesting unexpected metabolic regulation energetic resources during metamorphosis Medfly. Arch. Insect Biochem. Physiol. 56:97–109, 2004. © 2004 Wiley-Liss, Inc.
