The paper contains a description of the area of study and methods of collecting material in pine canopies in the Berezinsky Biosphere Reserve. The results of earlier studies by Byelorussian zoologists, who cut pine branches to collect, have been compared to the Moericke's pitfall traps method. The considerable d: (Terences in abundance observed suggest that in order to obtain a relatively accurate picture of tree canopy fauna both methods should be used on a complementary basis.
75 species belonging to five families of Calyptrata were recorded in the pine forests of the Berezinsky Biosphere Reserve. In pine canopies and the herb layer in one site, and in pine canopies only in two other sites were recorded the following: 8 species of the family Muscidae (Muscinae), 16 species of the family Calliphoridae, one species of the family Rhinophoridae, 13 species of the family Sarcophagidae and 37 species of the family Tachinidae. Most of them are widely distributed saprophages and parasitoids as well as predators of invertebrates and vertebrates. All the species recorded now in the families are new to the region studied. 30 of them are synanthropes. The fauna of Calliphoridae, Sarcophagidae and Tachinidae of the pine forests of the Berezinsky Biosphere Reserve in Byelorussia was compared to the fauna of blow flies, flesh flies and tachinid flies in a pine forest in the Kampinoski National Park in the Mazovian Lowlands in Poland.
The paper contains a list of dipteran species collected with the Moericke's traps method in pine canopies in the coniferous forests of the Berezinsky Biosphere Reserve in two years. The species belong to four families: Dolichopodidae, Syrphidae, Conopidae and Pipunculidae.
The material was collected In 1983-90 in Berezinsky Nature Biosphere Reserve. It contains more than 20,000 specimens of Orthopteroidea representing 3 orders, 5 families and 32 species.
A study conducted in 1989-1990 revealed 17 Neuropteroidea species of the families Raphidiidae, Coniopterygidae, Hemerobiidae and Chrysopidae as well as 7 species of Coccinellidae. The following species were the most numerous: Wesmaelius concinnus (Steph.) and Hemerobius stigma (Steph.) as well as Myrrha octodecimguttata (L.) and Anatis ocellata (L.).
Malaise's and Moericke's traps set in a mossy pine forest within the Berezinsky Biosphere Reserve have revealed 18 Pempilidae species and 44 Sphecidae species. The distribution of Pompilidae and Sphecidae in the forest was not uniform and dependent on the heterogeneity of the pine stand and the forest layer. Insects of both families were found to concentrate in the cutting, and Sphecidae, in addition, in the crown.
A study conducted in three study sites in the canopy layer of a pine forest in the Berezinsky Biospheric Reserve has yielded 7 species of Rhagionidae, 6 of Therevidae and 6 of Asilidae.
