摘要
本文对甘蔗赭色鸟喙象OtidognathusrubricepsChevrolat在甘蔗、玉米、竹子和类芦上的取食、发育和繁殖作了比较研究。结果表明 :成虫趋向取食甘蔗、在甘蔗上产卵 ;每雌产卵量、产卵历期、成虫寿命和卵孵化率以甘蔗为最高、最长 ,然后依次为类芦、玉米、竹子。甘蔗最有利于该虫的取食、发育和繁殖。
The feeding, development and reproduction of Otidognathus rubriceps Chevrolat on sugarcane, corn, bamboo and burmareed Neyraudia reynaudiana (Kunth) Keng were studied.The results showed adult preferred feeding and ovipositing on sugarcane.Corresponding with the order of four host plants, sugarcane, burmareed, corn and bamboo, the egg number/female, oviposition period, adult longevity and egg hatching rates of Otidognathus rubriceps Chevrolat increased. Sugarcane was the best for its feeding, development and reproduction.
