Natural History of the <em>Crambe feeder, Lixus circumcinctus</em> (Coleoptera: Curculionidae)
Abstract
Field investigations showed that Lixus circumcinctus Boheman 1835 (Coleoptera: Curculionidae) is a major herbivore species living on Crambe orientalis in northeastern Anatolia and on Crambe tataria in central Anatolia. Adults hibernate in the root crown of host plants. They associate with their hosts in the spring, feed on leaves, young stems and buds, and lay solitary eggs in the stem and lower leaves of petiole. Larvae open galleries oriented downward toward the root crown. Mature larva make a pupal case using plant fibers at the end of gallery, and pass the pupal stage in the late summer. Second generation adults appear in early autumn, overwinter in the same niche, and complete one generation a year. Crambe orientalis harbors 7 species of weevils in eastern Turkey, and Crambe tataria harbors 8 weevil species in central Anatolia.Investigaciones en el campo demostraron que Lixus circumcinctus Boheman 1835 (Coleoptera: Curculionidae) es una especie herbívora de gran importancia que vive en Crambe orientalis en el nororiente de Anatolia, y en Crambe tataria en el centro de Anatolia. Los adultos hibernan en la corona de la raíz de sus plantas hospederas. Estos se asocian con su hospedero en la primavera, cuando se alimentan de hojas, tallos jóvenes y brotes, y depositan huevos solitarios en tallos y en peciolos de las hojas bajeras. Las larvas construyen galerías orientadas hacia abajo, en dirección a la corona de la raíz. Al final de la galería las larvas maduras construyen una cámara pupal utilizando fibras de plantas y permanecen en estado pupal durante el verano. Una segunda generación de adultos aparece al principio del otoño, permanece en el mismo nicho durante el invierno, y completa una generación por año. Crambe orientalis es hospedera de 7 especies de picudos en el oriente de Turquía, y Crambe tataria, de 8 especies de picudos en el centro de Anatolia.
