Effect of Parasitoid Release Pattern on Whitefly (homoptera: Aleyrodidae) Control in Commercial Poinsettia
Under commercial poinsettia production conditions we compared two patterns of parasitoid release for the aphelinid whitefly parasitoid Eretmocerus eremicus Rose and Zolnerowich. We compared the currently used pattern of a fixed weekly release number (3 females per plant per week) to an experimental pattern in which more parasitoids were released early in the crop (wks 1-8), followed by a lower ...
متن کاملAn economic comparison of biological and conventional control strategies for whiteflies (Homoptera: Aleyrodidae) in greenhouse poinsettias.
The objective of this study was to evaluate the costs of biologically controlling infestations of silverleaf whitefly, Bemisia argentifolii Bellows & Perring, in New England greenhouse operations on poinsettia, Euphorbia pulcherrima Wild, ex Koltz, using the parasitic wasp Encarsia formosa Gahan (Nile Delta strain). Partial budget analysis was used to compare costs for conventional verses biolo...

متن کاملEffects of temperature and dietary sucrose concentration on respiration in the silverleaf whitefly, Bemisia argentifolii.
A system consisting of a flow-through chamber connected to a commercial infrared gas analysis system was developed to measure homopteran respiration during feeding. Using this system, respiration rates of 202 and 206 µmol CO(2) h(-1) g(-1) (4.96 and 5.04 ml CO(2) h(-1) g(-1)) were determined for whiteflies and cotton aphids, respectively, at 25 degrees C on diets containing 15% sucrose. These r...

Figure 1 shows a TaxPlot in which E. coli K12 has been selected as the reference genome for comparison of two strains of H. pylori, J99 and 26695. Each point in the figure represents a single E. coli protein. The X and Y coordinates represent the BLAST score for the protein’s closest match in the two strains of H. pylori. There are 217 E. coli proteins that are equally similar to proteins in th...
