Compsus viridivittatus

  • ANZEIGE

    Hello this is translated from Spanish to English so i hope it makes a bit of sense for you. i have not heard ppl actually keeping weevils before. they might be too difficult because the larvae eat roots of citrus. here the info i found.

    Compsus viridivittatus (Coleoptera: Curculionidae) eats from citrus in Colombia. Larvae consume roots and the adults leaves, flowers and fruits. It losses by decreases in leaf area causes greater than 50% in young trees and 20-30% in production trees. To determine feeding and oviposition preferences in commercial varieties, six varieties of citrus were used: valencia orange Citrus sinensis, sweety orange C. sinensis, arrayana mandarin C. reticulata, tahiti lime C. latifolia, bird lime C. aurantiifolia and volkameriana rootstock C. volkameriana. Leaf consumption was evaluated through no-choice and free-choice trials. Oviposition preference was determined through no-choice trials. C. viridivittatus fed on all of the materials evaluated. In free-choice, C. viridivittatus showed preference for valencia orange (644 mm (2)) and lower consumption in mandarin (44 mm (2)). In no choice, no significant differences were detected in the evaluated materials. The greatest oviposition (37 eggs) was observed when C. viridivittatus fed on bird lime, being significantly lower in tahiti lime (9 eggs). The results obtained in this study contribute to the guiding of integrated pest management programs that allow for the reduction of C. viridivittatus populations.
