  Introduction: Greenhouse whitefly, as an economic pest, has a wide and ubiquitous host range and causes great damage to many crops, including greenhouse plants. Due to the morphological characteristics and potential of resistance to chemical toxins, it is necessary to find suitable and compatible compounds for integrated control of this pest by increasing the effect and minimizing the adverse effect on the pathogenic fungus Beauveria bassiana.Methods: In this study, the effect of pathogenic fungus Beauveria bassiana alone and in combination with silica nanoparticles against second instar seeds and nymphs of Trialeurodes vaporariorum Westwood and germination power of pathogenic fungi using probit analysis, one-way analysis of variance and ANOVA SPSS software was examined.Results: LC50 values obtained from probit degradation as a result of the effect of different concentrations of silica nanoparticles and Beauveria bassiana against eggs after 7 days and against second instar nymph after 72 hours (643.97 mg / L and 170399 conidia/ ml) and (602.952 mg / L and 78379 conidia/ ml) were obtained, respectively.Results: According to the results of the present study, silica nanoparticles alone have higher toxicity than other treatments and in combination with B. bassiana can be used in integrated control of the important greenhouse whitefly pest. The most important advantage of using these compounds is their compatibility with the environment and the lack of resistance to insects against them.  Manuscript profile

  Gerbera is attacked by a large number of pests, one of the most important of which is greenhouse whitefly (Trialeurodes vaporariorum Westwood). Currently, it is controlled by chemical and large amounts of money are used to import insecticides to control this pest annually. In current research, the effect of Palizin and Imidacloprid in T. vaporariorum control in commercial gerbera greenhouses was compared. The experiment was performed in a commercial greenhouse in Pakdasht, Tehran. The same size and none flower gerbera pots were selected for further analysis. Before and after the experiment, the number of nymphs and adults were estimated. Selected factors were included: the pesticide in two levels, pesticide dose in three levels (0.5, 1 and 1.5), application time in three levels (hours 8, 12 and 16) and replications in a month in three levels (2, 4 and 6). Data was analyzed using Design Expert 10 software with RSM (Response Surface Method) method. Based on the result, the mortality percentage of whitefly adults during the use of Confidor is significantly higher than Palizin. Also the only significant factor was the pesticide type, and other factors will not make any significant changes in the response. Manuscript profile
