摘　　要：豆天蛾是一种日益受到人们青睐的食用昆虫。本实验在室内测定了豆天蛾各虫态及整个世代有效积温、发育起点温度和实验种群生命表。结果表明：在19-31℃内豆天蛾的各虫态均能正常发育。各虫态的发育速率随温度的升高而加快,在19℃发育历期最长,为100.89d,而在31℃下仅为47.10d。种群趋势指数在25.63℃时最高,为74.36,说明在此最适温度下豆天蛾可大量繁殖,解决市场供不应求的难题。Clanis bilineata tsingtauica Mell is one of the edible insects.Its biology was studied in the laboratory.The results showed that this insect could normally develop between19℃and31℃.Their developmental rate increased with increasing temperature.The longest immature duration was 100.89 d at 19℃,and the shortest was47.10 d at 31℃.The highest population increase index was 74.36 recorded at 25.63 ℃.It is concluded that a promising method for increasing C.bilineata tsingtauica number has been found,which might be useful for largescale commercial purpose.
