Effect of American Cyanamid CL-47031 on Fecundity and Longevity of the Boll Weevil1

Abstract
Usually when an insecticide is evaluated for its control of a particular insect, the only criterion of effectiveness is whether it killed the test species. However, other effects also may be important. For instance, Ouye and Knutson (1957) reported that house flies, Musca domestica L., which survived larval treatment with malathion lived fewer days and produced fewer eggs than untreated insects. Also, Adkisson and Wellso (1962) reported that adult pink bollworms, Pectinophora gossypiella (Saunders), which survived low dosages of DDT lived fewer days and produced fewer eggs than the untreated controls. Other similar studies were reviewed by Ascher (1964).
