| Trialeurodes vaporariorum (West.) is a pest of greenhouse vegetables and ornamentals and infests crops in Europe and in the American continent. In Brazil, just a few cases are known on economic crops, being all restricted to greenhouse crops. In 2003, in Itatiba and neighboring localities of State of São Paulo, Brazil, field infestations of T. vaporariorum were observed, mainly on tomato and green bean. So far, whitefly infestation in this area expanded to squash and kale also. Field studies are needed for determining interactions of T. vaporariorum with plants and natural enemies, injury levels, and methods of control. |

| This study aims to evaluate the control efficacy of greenhouse whitefly by co-application of entomopathogenic fungus Lecanicillium muscarium hybrid strain 2aF43 and greenhouse whitefly parasitoid Encarsia formosa, and to reveal the interaction between both natural enemies. Although, the emergence rate of adult greenhouse whitefly reached 93.2% in control plot, co-application plot indicated significantly lower emergence rate (4.2%). Co-application plot showed higher fungal infection compared with singularly L. muscarium inoculated plot. Parasitization rate in singularly E. formosa released plot reached 81.7% and emergence rate of parasitoid was 72.1%, but lower parasitization and emergence rate of parasitoid (13.2% and 2.0% respectively) were detected on... |

| Changes in production conditions associated with biological invasions can be complex. As a result, modeling invasive species management decisions can be difficult. Modeling these decisions is further compounded by externalities associated with spatial relationships among growers. In order to calculate optimal management decisions, an accurate bioeconomic model of the feedback between grower decisions and the new biological interactions created by an invasive species population is needed. In this paper, a bioeconomic model is used to explicitly analyze how externalities caused by spatial relationships among agricultural producers affect optimal invasive species management decisions. The example of the coordinated greenhouse whitefly management in the... |
