WebOct 2, 2024 · Such specialization manifests as plant mortality at high conspecific densities and/or in proximity to conspecific trees . Often it is estimated in terms of host range of natural enemies (e.g., ref. 25). However, the capacity to associate with multiple hosts does not translate necessarily to similar effects across those host species (22, 40). WebApr 8, 2013 · Host specialization is a ubiquitous character of phytophagous insects. The polyphagous population is usually composed of some subpopulations that can use only a few closely related plants.
