This 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.
