OBSERVATIONS ON THE EVOLUTIONARY CYCLE OF THE EURYGASTER INTEGRICEPS SPECIES IN THE NORTHEASTERN REGION OF ROMANIA

open access: yesCURRENT TRENDS IN NATURAL SCIENCES
Eurygaster integriceps, commonly known as the sunn pest, begins its biological activity in the second decade of April, when adults emerge from hibernation at temperatures of 12–16°C, with mass flights occurring on sunny days at temperatures above 18°C. Males appear a few days before females, and the migration to wheat fields is completed by May.
