Host-plant selection by 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. Many generalist, conifer-colonising beetles, for … WebThere is a long held and widely accepted view that insects use a sequence of behavioral responses in host selection. This was first recognized in parasitoids and later in …

Because many studies have highlighted the importance of the ratio and concentrations of plant volatiles for host location by phytophagous insects (Najar-Rodriguez et al. 2010; Webster et al. 2010; Cha et al. 2011), it is important to evaluate different dosages and ... WebHerbivores are dependent on plants for food, and have coevolved mechanisms to obtain this food despite the evolution of a diverse arsenal of plant defenses against herbivory. Herbivore adaptations to plant defense have been likened to "offensive traits" and consist of those traits that allow for increased feeding and use of a host. Plants, on the other hand, …
