“…While the adoption of biological control is desirable, the successful implementation depends upon the comprehensive understanding of predator–prey interactions, owing to their fundamental role towards ecosystem functionality and food web stability 4 . Several methods can be applied to quantifying these interactions 5 , 6 , including functional response 7 , numerical response 8 , kill rate 9 , and consumption rate 10 . Functional responses describe how the predation rate changes with resource density 11 .…”

In the current study, we investigated the functional response of Harmonia axyridis adults and larvae foraging on Acyrthosiphon pisum nymphs at temperatures between 15 and 35 °C. Logistic regression and Roger’s random predator models were employed to determine the type and parameters of the functional response. Harmonia axyridis larvae and adults exhibited Type II functional responses to A. pisum, and warming increased both the predation activity and host aphid control mortality. Female and 4th instar H. axyridis consumed the most aphids. For fourth instar larvae and female H. axyridis adults, the successful attack rates were 0.23 ± 0.014 h−1 and 0.25 ± 0.015 h−1; the handling times were 0.13 ± 0.005 h and 0.16 ± 0.004 h; and the estimated maximum predation rates were 181.28 ± 14.54 and 153.85 ± 4.06, respectively. These findings accentuate the high performance of 4th instar and female H. axyridis and the role of temperature in their efficiency. Further, we discussed such temperature-driven shifts in predation and prey mortality concerning prey-predator foraging interactions towards biological control.

“…In this section, experiments were performed mainly following previously published work [75,76]. Considering that A. gifuensis prefers to parasitize the 2nd instar of M. persicae and S. miscanthi [77,78], two phenotypes of aphid adults (winged and wingless adults) as well as 2nd star nymphs were employed as three groups to be treated with EBF (4 ng/μl diluted in trimyristoyl triglyceride (TAG, APPLYGEN)).…”

“…When the species richness of parasitoid wasps increases, the parasitism ratio decreases [100]. Furthermore, both host density and natal host significantly affected the self superparasitism of A. gifuensis on S. miscanthi [51], and the presence of aphid predator chemical cues (such as H. axyridis-related cues) influenced the foraging behavior and activity of A. gifuensis [75]. EBF triggers attack behavior in predators [101] and parasitoids [12,48], clearly serving as a stimulant for host/ prey finding and attacking.…”

“…However, these studies were not supported by chemical analysis. Furthermore, parasitoid females may also perceive other chemical cues that enable them to detect the presence of conspecific females, predators, and entomopathogens, thus avoiding competition or predation in the occupied patches [42][43][44][45][46].…”

Herbivore-induced plant volatiles constitute the first indicators of insect host presence, and these can affect the foraging behavior of their natural enemies. The density of insect hosts may affect the nature and concentration of these plant-induced volatiles. We tested the impact of infestation density (low, intermediate, and high) of the pea aphid, Acyrthosiphon pisum (Homoptera: Aphididae), feeding on the broad bean Vicia faba, on the attractiveness of the parasitoid Aphidius ervi (Hymenoptera: Braconidae), using a Y-tube olfactometer (infested vs. non-infested plants). The emitted volatile compounds from both infested and non-infested plants were collected and identified. In addition, two series of experiments were carried out to test the impact of the presence of a conspecific female parasitoid within the aphid/plant complex on the attractiveness to other females. Parasitoids were significantly more attracted to the plants with low and intermediate aphid infestation levels. The volatile blend composition of the infested plants changed in relation to aphid density and may explain the low attraction of parasitoids toward high aphid density. The presence of conspecific females on the aphid patch had no apparent impact on the behavioral choices of other parasitoid females. Our study adds a new aspect to understanding plant–aphid–parasitoid interactions, including the possibility that aphids may manipulate chemical cues of host plants affecting the orientation of parasitoids.
