BREEDING AREAS OF THE BLOOD SUCKING

MIDGES IN THE STEPPE ZONES OF UKRAIN

DON MEDICAL INSTITUTE

<u>SUMMARY</u>

In the Donetsk region, larvae and pupae of 18 midge
species of the genus Culicoides were found: C. nubeculosis,
C. riethi, C. puncticollis, C. salinarius, C. circumscriptus,
C. manchuriensis, C. homochrous, C. fascipennis, C. subfascipennis, 
C. ustinovi, C. maritimus, G. simulator, C. alazanicus,
C. odibilis, C. vexans, C. albicans, C. reconditus, C. punctatus, 
and Leptoconops borealis. The analysis of the lietarure [literature]
and the own data showed that in the Donetsk region, in
particular, and in the steppe zone in general breeding places
of midges are localized and focal. The association of midge
larvae of C. nubeculosis, C. riethi, C. puncticollis, C.
salinarius, C. circumscriptus and C. manchuriensis with
oozed wellheated water bodies, C. vexans larvae with drying
water bodies with grass vegetation, larvae of C. fascipennis,
C. subfascipennis, C. maritimus, C. simulator, C. edibilis,
C. reconditus, and C. punctatus with biotopes with grass
and sedge vegetation was observed. Breeding places of C.
homochrous, C. ustinovi, C. alazanicus have been found first
in the world. Larvae of C. alazanicus were found to develop
in shallow waters in scirpus of the river Kazenny Torets,
larvae of C. homochrous in shallow water bodies of floodlands
of the river severny Donets, and C. ustinovi larvae in
floodland water bodies grown with grass and sedge in the
river Kazenny Torets. Priazovie flood plains, salted water
maeshes [marshes] are places of mass breeding of C. riethi, C.
salinarius, C. manchuriensis, C. maritimus midges, less
so C. puncticollis and Leptoconops borealis.

In order to develop a method to safeguard against,
and measures to fight the blood sucking midges, it is not
enough to know the biology of the adult insects but also
the pre-imago phases of their development.
