“…Understanding the foraging behavior of parasitoids in response to chemical cues may be helpful in improving effectiveness of their control in the field (Powell et al ., 1998; Pérez et al ., 2007). Most present studies reported the efficient control of A. gifuensis against aphid Myzus persicae , but it is possible to exploit the potential of A. gifuensis to control other host aphids because of its non‐preference to different plant/aphid complexes.…”

The olfactory responses of Aphidius gifuensis to odors from two host plants (Nicotiana tabacum and Brassica napus ssp.) and their complexes with different infestation levels of two host aphids (Myzus persicae and Lipaphis erysimi) were respectively examined in an olfactometer. The results showed that female A. gifuensis did not respond to odors of undamaged or mechanically damaged host plants, but significantly responded to odors of aphid/plant complexes. Moreover, A. gifuensis responded significantly to odors of both M. persicae and L. erysimi/plant complexes when host plants were infested by high levels of aphids, suggesting that quantity of aphid-induced volatiles could be important for attracting A. gifuensis. When tested between aphid/plant complexes, A. gifuensis did not show its preference for either complex. The efficiency of A. gifuensis against aphids in open fields potentially could be improved by using its olfactory response to aphid/plant complexes.

“…With only one exception (Lo´pez Pe´rez et al 2007), in all these studies it has been shown that the volatile compounds released by an aphid infested plant selectively attract aphid predators and parasitoids towards their preys/hosts. This feature is referred to as indirect defence, to stress the fact that the plant defends itself from herbivore insects through the intervention of their specific natural enemies (Dicke et al 2003).…”

“…During the last 15 years, the key role of the plant in the recruitment of aphid antagonists has been recorded in a number of tritrophic systems (Guerrieri et al 1993;Reed et al 1995;Han and Chen 2002;Girling et al 2006;Blande et al 2007;Lo´pez Pe´rez et al 2007;Pareja et al 2007;Sasso et al 2007).

Aphids are economically important insect pests of agriculture and forest crops. They feed on phloem sap by extremely efficient mouthparts modified into long and flexible stylets. Adaptation to phytophagy is completed by an extremely ductile reproduction system that can alternate biparental and parthenogenetic generations. In order to reach plant phloem, aphids must overcome plant defences, either physically and/or chemically. However, plants respond to aphid attack by activating defence genes that lead to the production of physical barriers and/or chemical toxic compounds (direct resistance). In addition, attacked plants can attract the natural enemies of aphids by releasing specific volatile compounds (indirect resistance). We can take advantage of these different types of resistance in order to enhance the sustainable control of these phytophagous insects. In this review we summarize the main aspects of plant-aphid interactions, focusing on those issues that can have an economic application

“…The higher doses of HIPVs can result in significantly higher attraction among parasitoids [ 65 , 66 ], and in various cases the higher doses of HIPVs act as repellents as well [ 67 ]. Understanding the foraging behavior of parasitoids in response to chemical cues may be helpful in improving the effectiveness of their control in the field [ 52 , 68 ].…”

Plants have evolved a number of different chemical defenses, covering nearly all classes of (secondary) metabolites, that represent a major barrier to herbivory: some are constitutive; others are induced after attacks from herbivores (HIPVs) and may elicit the attraction of predators and parasitoids. Here, we studied how the female solitary endoparasitoid Aphelinus varipes responds to plant and host aphid volatiles in a series of experiments on five commercially important vegetables that were either healthy or infested with the aphid Myzus persicae: chili pepper, eggplant, crown daisy, Chinese cabbage and cabbage. The results for the olfactory responses of A. varipes showed that the presence of M. persicae increased the attraction of the endoparasitoid to the infested plants. In a second experiment, volatiles from highly attractive and repellent plants were obtained via headspace collection to investigate volatiles from healthy and aphid-damaged plants. The results for the differences in volatile profiles in response to aphid infestation in chili pepper cultivar were dominated by the volatile blends, including α-pinene, decanal and phthalic acid, while in cabbage they were dominated by isophorone. Moreover, when HIPVs with different concentrations were compared, α-pinene at a dose rate of 100 ng/μL attracted more parasitoids, and the comparison was useful to understand the mechanisms of plant secondary volatiles during aphid infestation and to provide new resources to control this insect pest. Overall our study shows how HIPVs can bolster tritrophic interactions by enhancing the attractiveness of parasitoids.
