Abstract:
... Previous observations that okra-leaf cotton, Gossypium hirsutum L., sustained less seed damage caused by pink bollworm (PBW), Pectinophora gossypiella (Saunders), than normal-leaf cotton prompted a search for the cause of the reduced damage. In one series of experiments, bolls of `Stoneville 7A' okra-leaf and `Stoneville 7A' normal-leaf cotton were infested artificially with PBW eggs or first inst ...

Abstract:
... Severe natural infestations of the beet armyworm, Spodoptera exigua (Hubner), in upland cotton, Gossypium hirsutum L., result in flower infestations as well as foliage infestations. Conventional insecticide applications did not control beet armyworms in the flowers when applications were applied in early morning before the flowers opened. This problem was remedied by delaying applications until fl ...

Adults of laboratory-reared Mediterranean fruit fly, Ceratitis capitata (Wiedemann), laid eggs, and mature larvae developed in green intact bolls of cotton, Gossypium hirsutum L., in laboratory cage tests. Cotton bolls collected from early-season plants (102 d old) supported more larvae that developed to pupae (70.07 +/- 13.13 pupae per kilogram of bolls) (mean +/- SEM) than bolls collected from t ...
