Synchronous seasonal variations of the irritability by malathion, fenitrothion, propoxur and DDT with the minimum in midsummer and maximum in the overwintering generation were previously discovered in a wild population of Anopheles martinius from Karakalpakia. After laboratory colonization of the species the fluctuations of irritability persisted in spite of the absence of diapause and insecticide pressure. The levels of irritability by the three former poisons were still synchronously fluctuating with the period of the fourth generation, but propoxur irritability was changing in a peculiar mode. The presence of a genetically regulated populational auto-oscillatory mechanism is supposed.
