Photoperiodical adaptation of the Azerbaijan population of Idaea degeneraria Hubn. (Lepidoptera, Geometridae)

Dr. Hokuma Kuliyeva

The ecological and physiological characteristics of the Azerbaijan population of a small brown-marked geometer (Portland Ribbon Wave) Idaea degeneraria Hubn. have been subjected to research for the first time. It has been determined that under the constant temperature of 250C (+10C) and humidity of 45-50%, duration of the development of a caterpillar phase does not depend on the length of daylight hours. Photoperiod affects the date of ecdysis and dynamics of a caterpillar’s weight: quantitative reaction on the photoperiod is more obvious in longday versions of 18 and 24 daylight hours a day. It has been established that the date of caterpillar-pupal metamorphosis, percentage of pupas, as well as the date of fly out of moths and the duration of imago as to the first day of flight, do not depend on photoperiod conditions for caterpillar maintenance. Early flight and high percentage (30%) of moths have been observed under 12-hour photoperiod, while the minimum number of moths was observed under the regime of 8-hours of daylight (1.25%).
