Identification of a whitefly species by genomic and behavioral studies.
Recognition of this new species, the silverleaf whitefly, is critical in the search for management options.
The Bemisia tabaci species complex
Comparative research, using a variety of techniques, forms the basis from which similarities and differences between populations can be inferred and seven groups within the species complex are proposed.
Description of a Species of Bemisia (Homoptera: Aleyrodidae)
The species has been demonstrated to be distinct from B. tabaci (Gennadius) by crossing experiments, studies on intraspecific and interspecific mating behavior, analysis of allozymic frequencies, PCR analysis of genomic DNA, and morphological evaluation.
Management of plant viral diseases through chemical control of insect vectors.
In this article we consider the role of epidemiological factors and transmission processes of insect-vectored viruses on the effectiveness of insecticides in a disease management program. We also
Bagrada hilaris (Hemiptera: Pentatomidae), An Invasive Stink Bug Attacking Cole Crops in the Southwestern United States
It is learned that the bagrada bug has a single population peak between July and October in urban areas dominated by native and introduced weeds, and two population peaks (March-May and September-November) timed with the production of cole crops in agricultural areas.
Proximity to citrus influences Pierce's disease in Temecula Valley vineyards
It is found that citrus groves have influenced the incidence and severity of Pierce's disease in grapes, and California grape growers should take additional care with vineyards located near citrusGroves.
Behaviors of Female Eretmocerus sp. nr. californicus (Hymenoptera: Aphelinidae) Attacking Bemisia argentifolii (Homoptera: Aleyrodidae) on Sweet Potato
Behaviors of Eretmocerus sp. nr. californicus Howard females on Bemisia argentifolii Bellows & Perring infesting sweet potato, Ipomoea batatas (L.) Lam, were described and quantified. Walking speeds
Courtship Behavior of Bemisia argentifolii (Hemiptera: Aleyrodidae) and Whitefly Mate Recognition
It is proposed that the discrimination of signals sent and received from courting whiteflies becomes more intense with each successive phase in the courtship cascade, resulting in courtships between reproductively incompatible whiteflies.
Biology of Aceria guerreronis (Acari: Eriophyidae) on queen palm, Syagrus romanzoffiana (Arecaceae)
It is found that 172.71 degree days are required for mites to mature from the egg to the adult stage, indicating this species is arrhenotokous.
Prey stage preference and functional response of the predatory mite Galendromus flumenis to Oligonychus pratensis
The consumption rate of G. flumenis at constant densities of O. pratensis eggs, larvae, protonymphs and deutonymphs was determined, and the functional response of predator females was defined, where the predator consumed significantly more eggs than other prey stages, and displayed a type II functional response on all prey stages.
