Host selection in phytophagous insects
WebHost selection by herbivorous insects is primarily thought to depend on attraction to olfactory cues emitted from the host species. However, the discrimination of these hosts from non-host species may also arise from the adaptive detection and avoidance of non-host cues, including visual characteristics.

Host-selection in phytophagous insects is a complex process mediated by many factors including oviposition stimulants [1, 2], feeding stimulants (phagostimulants) [], vision [], experience [], and deterrents [].The preference-performance hypothesis explains the phenomenon of host specificity by positing that adult insects … WebHost-race formation in phytophagous insects is thought to provide the opportunity for local adaptation and subsequent ecological speciation. Studying gene expression differences amongst host races may help to identify phenotypes under (or resulting from) divergent selection and their genetic, molecular and physiological bases.
