Description:
Temperature, starvation, and nutrition stresses, applied singly and in combination, significantly affected the susceptibility of chrysoperla carnea to Beauveria bassiana and varied in effectiveness according to insect age and gender. he nutrition stress caused the most significant increase in adult and larval mortality and larval developmental failure. arval mortality and developmental failure were also increased by the starvation stress. he temperature stress affected C. Carnea mortality only when used in combination with nutrition and/or starvation. ossible mechanisms for the effects of the stresses on C. carnea response to B. bassiana are discussed.
