Abstract

The leaf, stalk, flower, and fruit of the geophyte Asphodelus aestivus Brot. (Liliaceae) in east Mediterranean mesic habitats are mainly attacked by the monophagous mirid bug Capsodes infuscatus Brulle (Hemiptera: Miridae). The sexual reproductive performance of A. aestivus was examined under natural levels of insect herbivory at three different host densities at the same site. Plants in the low and medium density plots were heavily attacked by C. infuscatus and failed to produce fruits, while plants from high density plots were less intensively attacked and produced some fruits. The observed inversely density-dependent damages are discussed with respect to plant compensation, population dynamics, and sexual vs. asexual reproduction.
