New observation of cone flies attacking cones of Picea obovata and Larix sibirica in central Siberia

摘要

Two species of cone flies (Strobilomyia anthracina and S. svenssoni) emerged from puparia were collected under Siberian spruce (Picea obovata) trees in the central part of the Krasnoyarsk region, central Siberia. Parasites of the Figitidae and Braconidae families emerged from 28.1/100 of the puparia, and fungal and bacterial diseases destroyed 24.8/100 of the puparia. Weight and length of the puparia depended on the sanitary status. Two types of cone fly eggs were observed on spruce cones. At least three species of Strobilomyia (S. Infrequens, S. laricicola, and S. sibirica) attacked cones of Siberian larch (Larix sibirica) in central Siberia.
