“…Moreover, we suggest that another direct effect of thrips on hoverflies could be related to causing stress on their larvae with a later effect on fecundity. In a recent study, the presence of ants in aphid colonies reduced the performance and oviposition of E. balteatus through disturbing syrphid predation or with ants preying on syrphid larvae (Amiri-Jami et al, 2017). In a similar way, here we observed reduced oviposition in aphidinfested plants with thrips presence, and a reduced performance associated to that behavior.…”

“…Our results show that the fecundity of S. rueppellii was reduced, although larval development was not affected by thrips presence. This type of effects has been shown for the hoverfly E. balteatus, whose larval survival was not different when feeding on aphids on two different plant species, in contrast to its fecundity (Amiri-Jami et al, 2017). Similar results were found between thrips and predatory mites, where the net reproduction of Neoseiulus californicus (McGregor 1954) (Acari: Phytoseiidae) was reduced in the presence of thrips (Choh et al, 2017).…”

“…Most of the studies about the responses of predators to dual herbivory are mainly focused on the behavior of predatory mites (De Boer et al, 2008;Zhang et al, 2009;Lima et al, 2017) or predatory bugs (Moayeri et al, 2007), whereas predator performance, and effects of omnivorous arthropods, have received little attention so far. Predatory hoverflies (Diptera: Syrphidae) are important aphid natural enemies, which are often studied in the context of biological control (Brewer and Elliott, 2004;Pineda and Marcos-García, 2008;Almohamad et al, 2009;Amorós-Jiménez et al, 2014, 2015Amiri-Jami et al, 2017), being commercially used as biological control agents in greenhouse crops. Gravid syrphid females, searching for plants on which they lay eggs, are able to detect and avoid potential intraor interspecific competition (Hindayana et al, 2001;Fréchette et al, 2007;Pineda et al, 2007;Amorós-Jiménez et al, 2015).…”

Role of Thrips Omnivory and Their Aggregation Pheromone on Multitrophic Interactions Between Sweet Pepper Plants, Aphids, and Hoverflies

In complex food webs, plants are commonly attacked by multiple herbivorous species, affecting the preference and performance of other herbivores and natural enemies. The role of omnivorous insects in ecosystems may be more complex because of the consumption of both plant and animal organisms. However, the effect of omnivorous insects on herbivores and natural enemies, has received little attention so far. The main goal of this study was to investigate whether the dual herbivore interaction between aphids and thrips, an omnivorous pest, on a sweet pepper system, may affect different trophic levels, from plant and aphid performance until the third trophic level, i.e., preference and performance of the predatory hoverfly Sphaerophoria rueppellii. Additionally, we tested whether the aggregation pheromone of the thrips Frankliniella occidentalis, could disturb the oviposition behavior of the predatory hoverfly. Our results show that the presence of thrips decreases host plant and aphid performance. Furthermore, despite not affecting syrphid larval performance, thrips presence reduces fecundity of the adults that emerge from those larvae. Additionally, we observed that syrphids avoid ovipositing on plants with either thrips or thrips aggregation pheromone. The present study reveals how the presence of thrips or a semiochemical compound related to thrips, can impact the behavior and performance of an aphidophagous predator.

With increasing worldwide pressure on bee pollinator populations and an increase in insecticide resistance amongst pest insects, there is a growing need for diversification of pollinator and pest control systems. Syrphid flies (Diptera: Syrphidae) contribute ecosystem services to agroecosystems through their supporting roles as crop pollinators and predators of pests. Adult syrphids are important pollinators with high floral visitation rates and pollen carrying capacity, while predatory syrphid larvae are natural biological control agents, reducing aphid populations in both field and laboratory conditions. The present challenge is to determine whether syrphid flies have the potential for application as pollinators and in integrated pest management schemes as biological control agents. Currently, there are gaps in research that are hindering the use of syrphids as dual service providers. Such gaps include a lack of knowledge of syrphid floral preferences, the role and viability of adult syrphids as pollinators in natural and agro-ecological pollinator networks, and the predatory efficiency of larvae in field and glasshouse conditions. By reviewing relevant literature, we demonstrate syrphid flies have the potential to be used as pollinators and biological control agents.

Aphid–ant associations are often described as mutually beneficial interactions in which honeydew is traded for protection from predators and parasitoids. The aim of the present study was to determine parasitization avoidance in ant‐tended aphid colonies. Field experiments were carried out on two host plants: hoary cress Lepidium draba (Brassicaceae) and Canadian teasel Cirsium arvense (Asteraceae). Lepidium was host to Acyrthosiphon gossypii (Aphididae) tended by the ant Lasius turcicus (Formicidae) and attacked by two parasitoids, Trioxys asiaticus (Braconidae) and Lysiphlebus fabarum (Braconidae). Cirsium was host to Brachycaudus cardui tended by Crematogaster sordidula and attacked by L. fabarum and Aphidius colemani (Braconidae). The per capita population growth rate of A. gossypii was significantly higher in the presence of ants, while B. cardui was negatively affected, albeit non‐significantly. The parasitism rate of A. gossypii decreased significantly when tended by Lasius turcicus, but the presence of Crematogaster sordidula in colonies of B. cardui significantly increased parasitism. Our results indicate that the effects of ant attendance vary between different aphid–ant interactions. Moreover, parasitoids can benefit from the presence of ants under some conditions.
