Rearing Using an Artificial Diet and Oviposition of Embryotic Undeveloped Eggs of the Black Vine Weevil, Otiorhynchus sulcatus (Fabricius) (Coleoptera: Curculionidae)

Abstract

Female adults and larvae of the black vine weevil, Otiorhynchus sulcatus (Fabricius), were reared using an artificial diet consisting of soybean powder and carrot juice. The survival rate of adults reared using the artificial diet was not different from that using carrot root during the period of four months. Although the adults reared using the artificial diet became to laid more eggs than those reared using carrot root, they layed nonpigmented eggs that did not hatch. The larvae fed this artificial diet did not develop.
