In
this study, the effects of secondary metabolites on the feeding preference and
growth of generalist caterpillars, Agelastica
alni L., were investigated. Feeding experiment has been applied with a
total of 11 diet; 6 of which were prepared by adding different concentrations
of gallic acid (1, 3, 5 %) and quinine (0.125, 0.25, 0.5 %) to the control
diet, 3 diet of which prepared by adding different concentrations of gallic
acid and quinine. According to the results, the amount of gallic acid consumed
did not affect the food consumption and the amount of pupa lipids. However, the
amount of gallic acid consumed positively affects the pupal mass and the pupal
crude protein. In addition, the amount of quinine consumed negatively affected
the developmental performance of larvae except for the food consumption. As the
count of secondary metabolites in the diet increases, the pupal mass and the
pupal crude protein decrease. Overall, during the co-evolution processs, A. alni larvae may be able to adapt to
gallotannins. However, quinine, an alkaloid, is a feeding deterrence and growth
suppressor for larvae.
