“…For short-range cues, when close to the host, parasitoids may use defensive compounds, sex pheromones, and cuticular hydrocarbons (Borges et al, 1998(Borges et al, , 2003Laumann et al, 2009). When parasitoids are close to the host or have physical contact with it, semi-or non-volatile compounds, such as footprints and egg composition, become important for host final recognition, as well as other physical or visual factors, such as texture, color, and vibratory information (Borges et al, 2003;Aquino et al, 2012) (Figure 1 Telenomus podisi is an egg parasitoid of pentatomid bugs that prefers egg masses of the Neotropical brown stink bug, E. heros, whereas T. basalis shows preference for egg masses of the Southern green stink bug, N. viridula Sujii et al, 2002). Despite this preference, Tognon et al (2014), while studying the influence of original hosts on the chemotaxic behavior and parasitism of T. podisi, observed that when Tibraca limbativentris Stål (Hemiptera: Pentatomidae) was the original host, the females parasitized this species over E. heros, whereas those emerging from E. heros exclusively parasitized E. heros' eggs, suggesting that the original host can exert influence on their choice.…”
