Controlled laboratory experiments were conducted to study the influence of temperature on production of eggs by a sunflower stem weevil Cylindrocopturus adspersus. Maximum egg production occurred when the temperature was 30± 1°C. At 27C the rate of egg production was lower than at 30°C but significant only at the P < 0.1 level. At 20, 23. and 35C egg production was significantly lower than at 30°C (P < 0.05) indicating that temperature can be an important factor in regulating the fecundity of this species.
