ABSTRACT
To insects, the perception of chemical signals through long distance is highly important in the host localization process, since such signals provide precise information about them, such as developmental stage, physiological condition, and location. The efficiency in responding to such signals constitutes an important adaptive factor because besides providing access to food and supplying their nutritional needs, it may mean finding a place for mating, oviposition, and progeny survival (Dicke 2000; Bede et al. 2007).
