Host selection in phytophagous insects
WebFeb 21, 2008 · Fitness trade-offs among host plants form the basis for divergent selection and ultimately ecological specialization in phytophagous insects, from which reproductive isolation arises as a byproduct (Rice and Hostert 1993; Funk 1998; Feder and Filchak 1999; Schluter 2000; Nosil et al. 2002). Microbial mutualists that interact with the host plant ... WebDec 16, 2003 · Abstract Insect learning can change the preferences an egg laying female displays towards different host plant species. Current hypotheses propose that learning may be advantageous in adult host selection behaviour through improved recognition, …

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.
