[Influence of temperature on the fecundity and attack of Catolaccus grandis (Burks) (Hymenoptera, Pteromalidae), parasitoid of the cotton boll weevil, Anthonomus grandis Boheman (Coleoptera, Curculionidae)]

Abstract: The effects of the temperature on the fecundity and attack of Catolaccus grandis, a parasitoid of Anthonomus grandis, were determined under laboratory conditions at constant temperatures of 20, 25 and 30°C. The data obtained were used to calculate life and fertility tables, from that we concluded the following: (1) pre-ovipositional, high fecundity, and declining fecundity periods of C. grandis are function of the temperature, (2) Iongevities of males and females of C. grandis are affected by temperature, (3) one hundred percent of boll weevil larvae die when paralized by C. grandis females, (4) the action of C. grandis against boll weevil is not only due to larvae, but also to parasitic action of the adult females that inject toxins into the host and causes its death, (5) the attack numbers of C. grandis is a function of the temperature, (6) the periods of high attack, high paralization, and high: parasitism of C. grandis tend to decrease when the females are submitted to higher temperatures, (7) the reproduction potential of C grandis is similar to that of A. grandis, and (8) C. grandis has potential for suppressing boll weevil populations.
