In the conditions of the Republic of Belaru in course of the research there was studied cucumber diseases transmission by dipterous phytophages. In greenhouses of Belarus the phytophages of the group Diptera are spreading. This complex includes Sciaridae (sciarides), Psychodidae (moth flies or drain flies) and Ephydridae (shore fly, sometimes brine fly). To confirm the contamination of the dipterous phytophages' imago by mushrooms - cucumber pathogens, using the methodology of James. As a result of realized research it was found that the phytophages from Diptera group are the disease agent vectors. It was revealed that 50% of shore fly imago, 36.7% of sciarides and 30.6% of moth flies of greenhouse coenosis are contaminated with disease agent fungi: Botrytis spp., Fusarium spp., Alternaria spp. It was determined experimentally that dipterous phytophage imagoes function as vectors for plant pathogens Botrytis cinerea Pers., Fusarium oxysporum (Schlecht.) Snyd. Et Hans., Alternaria cucumerina (Ellis et Ewerth) Elliot. Shore flies Scatella stagnalis Fll. imagoes have shown comparatively high ability to disease agent transmission.
