槟榔红脉穗螟Tirathaba rufivena Walker在温度为20,24,28±1℃和相对湿度85～95％条件下,用槟榔花饲养,完成一代分别需时55～64天(平均60.87±5.65天),37～43天(平均39.52±3.12天)和25～29天(平均27.12±2.83天)。每雌虫每日产卵4～57粒(平均18.90±8.56粒),一生产卵18～107粒(平均51.34±13.34粒)。卵的孵化率为95.6％。雌雄性比为1:0.89(雌/雄)。根据有效积温计算,红脉穗螟在海南岛一年发生10～11代。 Betel red-footed borer, Tirathaba rufivena Walker, was bred with betel flower at temperature of 20, 24, 28 ± 1 ℃ and relative humidity of 85 to 95% for 55 to 64 days (average, 60.87 ± 5.65 days) , 37-43 days (mean 39.52 ± 3.12 days) and 25-29 days (mean 27.12 ± 2.83 days). There were 4 ~ 57 eggs per female per day (average 18.90 ± 8.56) and 18 ~ 107 eggs per day (average 51.34 ± 13.34). The hatching rate of eggs was 95.6%. Male to female ratio of 1: 0.89 (female / male). According to the calculation of effective accumulated temperature, red pulse ear borer occurs in Hainan Island 10 to 11 generations a year.
