dc.descriptionThis paper examined: larvae growing and getting reproductive age individuals of long – horned beetle (Morimus funereus) in laboratory conditions, analyzing the amylase activity and isoamylase profiles of M. funereus larvae and great capricorn beetle (Cerambyx cerdo) larvae depending on the nutrient substrate and environmental conditions, purification and biochemical characterization of the major amylase isoform of M. funereus larvae and purification of the major amylase isoform of C. cerdo larvae. Larval develop of M. funerus larvae in the laboratory from eggs to reproductively capable individuals in two generations were described. It is shown that growing growing larvae in laboratory conditions and constant availability of food larval development was reduced, and that in the second generation higher uniformity of larvae in all of the parameters that describe the larval development was noticed. It was found that there are differences in amylase activities and isoamylase profiles of M. funerus and C. cerdo larvae depending on the substrate and nutrient conditions in the environment where they develop, thus confirming their polyphagy and high adaptability. The main α-amylase isoform of M. funereus larvae was purified to homogeneity 112 times with a yield of 15% and was biochemically characterized. Its molecular weight is determined to be 33 kDa, pI value - 3.2, optimum pH - 5.2 and optimum temperature - 45 ° C. α-Amylase activity of M. funureus larvae is depended on concentration of Ca2 + ions. Inhibitors from wheat inhibit the M. funereus amylase. Midgut amylase of M. funereus larvae shows activity towards raw starch. The main α-amylase of C. cerdo larvae was partially purified from crude extract, and the isoenzyme pattern level using two types of FPLC chromatography. Molecular mass of midgut α-amylase of C. cerdo larvae was 34 kDa and pI was less than 3.5.en
