title: [Photoperiodic induction of the diapause in the egg phase of the blood-sucking midge, Culicoides pulicaris punctatus Mg. (Diptera, Ceratopogonidae)].
abstract: Photoperiodic induction of diapause in C. p. punctatus was studied at a constant (25 degrees) and varying temperature (16 to 18 degrees). Photosensitivity of females and eggs was established. The first and second generations of C. p. punctatus have a photoperiodic reaction of a long-day type. The effect of the light day and temperature on females of different generations is dissimilar. The tendency of diapause is higher in autumn females.
