The bioecological characteristics of Rhinusa acifer Caldara (Coleoptera: Curculionidae) on Verbascum sinuatum L.

Abstract :

In this work, the bioecological characteristics of Rhinusa acifer Caldara (Coleoptera: Curculionidae) living on the weed Verbascum sinuatum L. in Kahramanmaraş province were determined. Galls formation on the plant Verbascum sinuatum L. was observed in the field investigations in 2016, and these galls were brought to the laboratory and analyzed. R. acifer sp. of Curculionid and parasitoids were obtained from these galls. The feeding, damage and biology of R. acifer living on V. sinuatum were observed by following up the phenology of V. sinuatum periodically starting from the first week of March for the field investigations in 2017. The egg laying of R. acifer on V. sinuatum, the emergence of egg, larva, pupa, adult and parasitoids of R. acifer in the galls resulting from the feeding of the hatched larvae were observed, and their biologies were determined. The parasitoids, Calosota aestivalis (Curtis, 1836) and Entodon mecini (Dalman, 1820) were identified. C. aestivalis of these was the most intense parasitoid, and it was ascertained that this parasitoid was suppressing R. acifer. The first egg laying of R. acifer was released as April 24, the first emergence of larva on May 2, the first occurrence of pupa and adult on June 24, 2017 and on the same date, the pupas of the parasitoids were obtained
