Males of the sugarcane borer,Migdolus fryanus (Coleoptera: Cerambycidae), are attracted to females by means of a sex pheromone. Mating usually occurs during a few days from October to March under field conditions in São Paulo State, Brazil. This work reports on mating of this species as affected by daily climatic factors, during a single nuptial flight. Maximum male capture by the natural sex pheromone occurred from 10∶00 to 11∶00 AM at air and soil temperatures of 30.0°C and relative humidity of 57.0%. As these temperatures increased, females burrowed into the soil, as they are more sensitive to heat than males. Thus, it was concluded that sex pheromone-mediated mating in this cerambycid is directly affected by temperatures of air and soil.
甘蔗钻心虫(鞘翅目:天牛科)的雄虫通过性信息素来吸引雌虫。在巴西圣保罗州的野外条件下,交配通常发生在 10 月至 3 月的几天内。本研究报告了在单一婚飞期间,受每日气候因素影响的这种物种的交配情况。在上午 10 点到 11 点,当空气温度和土壤温度为 30.0°C,相对湿度为 57.0%时,利用天然性信息素捕获的雄性数量最多。随着这些温度的升高,雌虫钻入土壤中,因为它们比雄虫对热量更敏感。因此,可以得出结论,这种天牛科的性信息素介导的交配直接受到空气和土壤温度的影响。
