Interpretive Summary:

Technical Abstract: Fewer (20%) adult silverleaf whiteflies, Bemisia argentifolii Bellows and Perring, were caught in CC traps compared with suction traps. However, trap catches in the two type traps were significantly correlated. In choice and no-choice trap studies on bare ground, more adult whiteflies were caught in CC traps placed at the ground level compared to traps placed dfrom 30 to 120 cm above ground. Year round CC trap catches averaged on a weekly basis for Imperial Valley, California in 1996 and 1997 and Palo Verde Valley in 1997, showed patterns of population fluctuation that are typical in the southwestern United States. Short term whitefly adult population fluctuations in most cases appeared due to occasional wind and rains, whereas overall fluctuations reflected seasonal temperature and host density effects. Results indicate that the CC trap may be a useful tool for monitoring seasonal whitefly adult populations in any specific period of time.
