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
