Distribution and Sampling of Bemisia argentifolii (Homoptera: Aleyrodidae) and Eretmocerus eremicus (Hymenoptera: Aphelinidae) on Cantaloupe Vines

Studies were conducted to examine the spatial distribution of immature Bemisia argentifolii Bellows & Perring and immature Eretmocerus eremicus Rose & Zolnerowich on cantaloupe vines and to develop efÞcient sampling plans. More B. argentifolii eggs were found on the 3rd leaf from the terminal of a cantaloupe vine than on any other leaf. The density of whiteßy nymphs peaked at leaf position 8, w...

Bemisia tabaci (Homoptera: Aleyrodidae) instar effects on rate of parasitism by Eretmocerus mundus and Encarsia pergandiella (Hymenoptera: Aphelinidae)

Studies were conducted to compare preference among Bemisia tabaci Gennadius, biotype B instars for parasitization by Eretmocerus mundus Mercet and Encarsia pergandiella Howard when provided one instar only, two different instars, and four different instars simultaneously. In the single-instar no choice treatment, Er. mundus was more successful in parasitizing the younger host instars, while En....

Reproduction and development of Eretmocerus eremicus (Hymenoptera: Aphelinidae) on Trialeurodes vaporariorum (Homoptera: Aleyrodidae)

Eretmocerus eremicus is the most abundant parasitoid of the Bemisia complex in North America. It can parasitize equally successfully the most common whiteflies in greenhouses, Trialeurodes vaporariorum and the Bemisia complex. The parasitoid is used in Europe for whitefly control, either alone or in combination with releases of Encarsia formosa. Life-cycle and demographic parameters of this par...

Behaviors of Female Eretmocerus sp. nr. californicus (Hymenoptera: Aphelinidae) Attacking Bemisia argentifolii (Homoptera: Aleyrodidae) on Cotton, Gossypium hirsutum, (Malavaceae) and Melon, Cucumis melo (Cucurbitaceae)

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 walk...
