| Abstract: | Through rearing tests and observations under laboratory conditions, biological characters and mating behavior of Dahurian casebearer (Coleophora dahurica Flkv.) adults were studied in this paper. Results discovered that the time of emergense of male adults was 24h to 36h earlier than that of female adults. The peak of sex pheromone secretion of the female adults appeared of 24h to 42h after the emergence. The reaction of male adults on the sex pheromone was most sensitive during 30h to 48h after emerged, so the earlier emergence of the male adults was favorable to mating. The phenomenon of repeated mating did not exist in female adults, but the male adults could mate for several times, with maximum of 4 times. There was a definite behavioral reaction during the mating period of male and female adults, and the certain period of feeding and mating times could affect the adults longervity to a certain degree. |
