Development of the B-biotype of Bemisia tabaci (Gennadius, 1889)(Homoptera: Aleyrodidae) on three varieties of pepper at constant temperatures. [link]Paper  abstract   bibtex   
Phenology models for the B-biotype of Bemisia tabaci on three varieties of Capsicum annuum (Morrón, Piquillo and Yolo-Wonder) were elaborated by fitting observed developmental times at seven constant temperatures (17, 20, 23, 26, 30, 33 and 35°C) to different mathematical functions. The number of generations of the B-biotype of Bemisia tabaci in Almeria, one of the most important horticultural regions in Spain, was also estimated. The observed developmental times decreased as temperature increased, except at 35°C. The most accurate developmental rates were determined with the Lactin model r(T)=eρT-e[ρTm-(Tm-T)/b]+λ (modification 2 of the Logan model). The optimal temperature on the three varieties was around 32°C and the maximum lethal temperature ranged from 37.5°C (for egg and nymph on Morrón) to 41.2°C (for egg and nymph on Yolo-Wonder). The best lower development threshold (c) and thermal constant (K) estimates were obtained with the linear model tT=K+ct, where t=development time in days; T=temperature in °C, and with the IMPACT-DDU Program, respectively. The lowest value of c was determined on Piquillo (8.7°C). The thermal constant ranged from 93 to 108 Degree-Days (DD) for eggs and from 288 to 302 DD for nymphs. For the complete period (from adult to adult) the thermal requirement estimate was greater on Yolo-Wonder (437 DD) than was on Morrón (401 DD) and Piquillo (404 DD). The number of cumulative generations in Almería (Spain) through 1998-99 was 19 on Morrón and Piquillo and 18 on Yolo-Wonder.
