摘　　要：在28℃、相对湿度75%条件下,对大黑甲(Zophobas opacus(Sahlberg,1823))进行饲养,观察其生物学特征。结果表明:大黑甲的发育历期包括成虫期60～90 d、卵期6～7 d、幼虫期90～110 d、预蛹期3～4 d、蛹期10～11 d。观察了各虫态的生活习性,发现该虫食性杂,在群集环境下出现老熟幼虫化蛹抑制、成虫及幼虫自相残杀等现象,对幼虫土中做茧,成虫交配、产卵及前胸和腹部的两对防御腺分泌两种化学防御物质等行为进行描述。Zophobas opacus（Sahlberg,1823） was raised in the laboratory at 28℃,RH 75%.The result showed that its growth period included the adult stage（60-90 days）,the egg stage（6-7 days）,the larval stage（90-110 days）,the prepupal stage（3-4 days） and the pupal stage（10-11 days）.Meanwhile,its living habits were observed,indicating that this beetle was polyphagous;the pupation of mature larvae was inhibited and the cannibalism of adult and larvae was crowded.The mature larvae could construct a cocoon in earth.The adult secreted two chemical defence substances by two pairs of defensive glands in prothoracic and abdominal,copulation,reproduction and so on.
