Behaviors of Eretmocerus sp. nr. californicus females attacking Bemisia argentifolii Bellows & Perring infesting cotton, Gossypium hirsutum L., and melon, Cucumis melo L., were quantified. Adult female behaviors were described and quantified for Eret. sp. nr. californicus to establish a behavioral time budget analysis. Females readily searched for host whitefly nymphs on cotton leaves with walking speeds averaging 0.5 mm/s. Females remained infrequently on melon leaves; those that did remain and search for hosts averaged walking speeds of 0.33 mm/s. The duration of host assessment by antennation was related to subsequent behaviors. Rejecting a host was a shorter process than …
