Kari Heliövaara, Rauno Väisänen. (1986). Parasitization in Petrova resinella (Lepidoptera, Tortricidae) galls in relation to industrial air pollutants. Silva Fennica vol. 20 no. 3 article id 5276. https://doi.org/10.14214/sf.a15455

Paratization of Petrova resinella L. in the gall stage was studied in the surrounding of Harjavalta, south-western Finland, in relation to industrial air pollution. Of the studied 283 galls, 28% produced a moth, 52% of the larvae/pupae were paratisized, and 20% were empty or contained a dead larva. The proportion of paratisized galls did not depend on the distance from emission sources of industrial air pollutants.
