Differential variation in development of the B- and Q-biotypes of Bemisia tabaci on sweet pepper Capsicum annnuum L. at constant temperatures

Developmental rates of the B- and Q-biotypes of Bemisia tabaci (Gennadius, 1889) were studied at seven constant temperatures (17, 20, 23, 26, 30, 33, and 35°C) on sweet pepper, Capsicum annuum L. ('Morrón'). The egg incubation period and the times required to complete development at all im...
