“…Rising temperature affects plant growth through its influence on physiological, metabolic, and biochemical factors such as plant photosynthesis, transpiration rate, CO 2 intake, foliar chemistry, and resilience to biotic factors (Holopainen & Gershenzon, 2010; Jamieson et al, 2017). Besides plants, rising temperature also affects the behaviour of insect herbivores (Kuczyk et al, 2021) and their associated natural enemies (Chen et al, 2021b) and have recently received research attention (e.g., Jafari et al, 2020). However, how rising temperature causes changes in the interactions among plants, insect herbivores and natural enemies that may have critical implications for the future management of pest species in agro‐ecosystems are little explored.…”

Potato, a cool-weather crop, emits volatile organic compounds (VOCs) which attract the specialist herbivore, Phthorimaea operculella, but also this herbivore's parasitic wasp, Trichogramma chilonis, an important biocontrol agent. What happens to this trophic system when heat stress challenges this agro-ecosystem? We studied how high temperature (HT) pre-treatments influence potato's VOC emissions and their subsequent effects on the preferences of insects, as evaluated in oviposition assays and Y-tube olfactometers. HT pre-stressed plants were less attractive to P. operculella adult moths, which were repelled by HT VOCs, but increased the recruitment of the parasitoid, T. chilonis, which were attracted. VOC emissions, including the most abundant constituent, ß-caryophyllene, were enhanced by HT treatments; some constituents elicited stronger behavioural responses than others.Transcripts of many genes in the biosynthetic pathways of these VOCs were significantly enhanced by HT treatment, suggesting increases in de novo biosynthesis. HT increased the plant's stomatal apertures, and exogenous applications of the hormone, ABA, known to suppress stomatal apertures, reduced leaf volatile emissions and affected the HT-altered plant attractions to both insects.From these results, we infer that HT stress affects this plant-insect interaction through its influence on VOC emissions, potentially decreasing herbivore ovipositions while increasing ovipositions of the parasitoid.

“…Most members of parasitoid wasps are known as very important agents of aphid biocontrol and play a critical role to suppress aphidpopulations (Jones et al 2003;Rashki et al 2020). Several studies have shown that parasitoid wasps were more effective on controlling cereal aphids (El-Hag et al 1996;El-Serafy 1999;Schmidt et al 2003;Thies et al 2005;Slman 2006;Caia et al 2009;Saleem et al 2009;von Burg et al 2011;Zhang et al 2019;Jafari et al 2020;Zhang et al 2020;Sepúlveda et al 2021). This effect of parasitoid wasps was obvious when this study Cereal aphids and their natural enemies.…”

Cereal aphids are known as serious pests that cause considerable yield losses of wheat production. In this study, cereal aphids and their common natural enemies inhabiting the commercial wheat crop were investigated between February and April 2013 as a preliminary study in the Hail region, northern Saudi Arabia. Results showed that wheat crops were infested by four aphid species including the Russian wheat aphid Diuraphis noxia Kurdjumov, the English grain aphid Sitobion avenae Fabricius, the bird cherry-oat aphid Rhopalosiphum padi L. and the greenbug aphid Schizaphis graminum Rondani (Homoptera: Aphididae). The Russian wheat aphid D. noxia, however, was the most abundant species compared to other aphid species, totaling 343 individuals which represented 39.80% of all cereal aphids. The results showed a diverse community of specialist natural enemies that were associated aphids including parasitoid wasps as a complex and one Braconid species Aphidius matricariae Haliday (Hymenoptera: Braconidae), three coccinellid species (Adonia variegate Goeze, Coccinella quinquepunctata L. and Coccinella septimpunctata L.) (Coleoptera: Coccinellidae), one species of lacewing Chrysopa sp. (adults & larvae) (Neuroptera: Chrysopidae) and one species of hoverfly Eristalinus aeneus Scop. (adults and larvae) (Diptera: Syrphidae). This study, also, recorded a high abundance of polyphagous predators that included two species of ground beetles involving the black beetle Calosoma olivieri Dejean and Calosoma imbricatum Klug (Coleoptera: Carabidae), and spiders (Araneae) as generalist natural enemies of cereal aphids. In this article, population dynamics of captured cereal aphids and their common natural enemies, and their correlations will be described and discussed.
