The conidia of Pandora neoaphidis were exposed 15, 30, 60 and 90 minutes to UV rays of 254 nm and 366 nm. It was proved that the conidia loose germinability faster when course of 90 minutes of the exposition around 70 conidia loose the germinability. This points to the fact that the most of conidia exposed to the direct sun radiation during the typical summer day can loose the germinability and that the UV radiation is an important factor of the mortality of conidia. The conidia exposed to the diffuse light, in the shadow of plants loose the germinability considerable more slowly. The exposition of the conidia to the rays of 366 nm, has less harmful effect on the germination of conidia. Harmful effect of UV rays of 254 nm turns out also in the shorter length of the initial hyphae of the exposed conidia.
