| preferential feeding and occupation of sunlit leaves favors defense response and development in the flea beetle, altica brevicollis coryletorum--a pest of corylus avellana. | the monophagous beetle, altica brevicollis coryletorum, is a major leaf pest of corylus avellana (common hazel). in contrast to majority of the other studied species of shrubs, sunlit leaves are grazed to a much greater extent than shaded leaves. since the observation of a link between leaf irradiance level and a. brevicollis feeding is unique, we hypothesized that feeding preference of this beetle species is related to the speed needed to escape threats i.e. faster jumping. we also hypothesized ... | 2015 | 25927706 |
