    The ’midge blight’, in which the raspberry cane midge (Resseliella theobaldi) has an important role, is the greatest problem in the raspberry protection. The basis of the chemical protection against raspberry cane midge is the prediction of adult midge emergence. Before the application of sex pheromone traps developed for the investigation of flight pattern, the usage of the accumulated temperature was attempted for the prediction of egg laying, but these temperatures are different in each country. The aim of this paper is to give information on the time of raspberry cane midge emergence and flight pattern by using sex pheromone traps and accumulated temperature calculation.

    The abundance and species diversity of phytoseiids were studied in the evergreen collection of the Corvinus University of Budapest at Soroksár from March to August 2010. 329 phytoseiid mite specimens were collected from 15 cultivars of coniferous trees belonging to the following 4 genera: Juniperus, Abies, Picea and Pinus. 6 phytoseiid mite species have been identified: Amblyseius andersoni (Koch, 1957), Amblyseius tenuis Westerboer 1963, Anthoseius bakeri (Garman, 1948), Anthoseius involutus Livshitz et Kuznetzov 1972, Typhlodromus baccetti Lombardinii 1960 and Typhlodromus cotoneastri Wainstein 1963. 
    The dominant phytoseiid species were Amblyseius andersoni and Anthoseius involutus.
    Amblyseius tenuis and Typhlodromus baccettii are new to the Hungarian fauna. Typhlodromus baccettii was found on Juniperus scopulorum 'Silver Star' and 'Moonglow' while Amblyseius tenuis was collected from Picea glauca 'Alberta Globe'.
