Abstract

The effect of biochemical parameters i.e. total chlorophyll content, peroxidase and polyphenol
oxidase activity was studied in resistance and susceptible sorghum lines to the sorghum shootfly
and their cross combinations. The lower amounts of total chlorophyll content and high enzyme
activity were observed in resistant lines and crosses involving resistant x resistant or resistant x
susceptible constitution. The higher enzyme activity might be inducing and activating an antibiosis
mechanism leading to the reduction in the extent of damage caused by shootfly. The lower
amount of chlorophyll content turns the leaves yellowish green and probably make them
unattractive for oviposition.
