BIONOMICS OF THE TEAK BEEHOLE BORER, XYLEUTES CERAMICUS, IN NORTHERN THAILAND: MATING BEHAVIOR

Abstract

Female displayed calling behavior from 20:00 to 23:00 and males responded to the calling of females with wing-fluttering. Males approached females with fluttering wings and copulated them. Females copulated only once but males copulated twice. Males walked up wind and approached females when virgin females were placed windward on an olfactometer. In the field, four males were captured on the traps baited with virgin female in both 1989 and 1990, although no male was captured on the traps baited with crude extract of sex pheromone. Some of the chromatographically separated fractions, however, elicited wing- fluttering of male moths when exposed to air-puffing.
