Abstract

Experiments on daily exposure of gypsy moth larvae to heat stress have shown that it leads to an increase in the survival rate of larvae with reduced adaptation to artificial diet (AD) and a decrease in the survival rate of larvae well adapted to AD. It has been found that acetylcholine esterase and tyrosinase activities and the concentration of tyrosine derivatives are reduced significantly in stress-exposed larvae. The conclusion is drawn about a possible relationship between change in the level of larval adaptation to food and a switch in metabolism of tyrosine derivatives from hormone synthesis to melanin synthesis pathway.
