Description The aim of the study was to test the effect of three flavonoids on growth and survival of
Helicoverpa armigera (Hüb) and Spodoptera litura (Fab.). A set of experiments were carried out with
varying concentrations of three flavonoids namely chlorogenic acid, quercetin and rutin at 23±1ºC on
growth, development and mortality of larvae of pod borer Helicoverpa armigera and tobacco caterpillar
Spodoptera litura in artificial diets. Rutin caused significant effect on the inhibition of H. armigera larvae
in higher concentrations, where a proportion of larvae spent between 30-51 days in excess time in larval
stage III-V instar which had negative impact on growth because of cessation of feeding by the larvae. H.
armigera larvae formed cocoons of their diets and lay still inside the cocooned diet. Healthy H. armigera
moth emergence was common in chlorogenic acid and quercetin, but the moths did not produce any
progeny. In case of S. litura, rutin alone had a significant effect on arrested larval development, pupal
mortality and malformed adults compared to artificial diets with quercetin and chlorogenic acid. The
increase in concentrations of rutin did not show proportionate increase in mortality of the larvae. The
average excess days at all concentrations of quercetin and chlorogenic acid ranged between 40-55 days.
These results indicate a delay in development and suggests that rutin interferes in with physiological
processes in both insects at the time of molting.
