“…Several studies have demonstrated the nutritional value of A. gossypii and/or M. persicae for these predators, as feeding on larvae of H. convergens and C. sanguinea with these aphids shortens larval development compared to feeding on other aphid species without compromising the biological fitness of the adult stage (Golizadeh & Jafari‐Behi, 2012; Obrycki & Tauber, 1982; Wipperfürth et al, 1987; Zarpas et al, 2007). In addition, both predators have similar developmental times under laboratory conditions and a diet based on A. gossypii (Boiça‐Júnior et al, 2004; Işikber & Copland, 2001, 2002), a species that predators would consume as their main food resource in pepper fields. Other prey species found in the stomach contents of Coccinellidae larvae include the species B. tabaci and Cecidomyiidae sp.…”

Viruses and aphids, the most recent vectors of viruses (Hemiptera: Aphididae) of the genera Myzus and Aphis, are the main phytosanitary problems of Capsicum spp. (Solanales: Solanaceae) agricultural systems in Colombia. The incorporation of biological control in integrated pest management (IPM) programmes, which can be used to reduce aphid populations in solanaceous crops, is hampered by the lack of information on the natural enemy community, such as parasitoids, predators and generalist aphidophagous. For this reason, the objective of this research was to determine and characterize the community of generalist aphidophagous (Coccinellidae and Syrphidae) in the cultivation of chilli pepper in south‐western Colombia, and to characterize their diet through stomach content analysis using next‐generation sequencing (NGS) techniques. Two species of Coccinellidae and one species of Syrphidae were the most abundant predators in commercial crops of Capsicum spp. and fed preferentially on aphids that attacked the pepper plants. The characterization of the diet of these predators using molecular tools revealed intraspecific predation, secondary predation of aphid parasitoids and consumption of alternative prey to the aphids attacking the pepper plants. Differences in diet composition were observed between larval and adult coccinellids, and between coccinellids and the hoverfly species studied. The results suggest that dominant predators may be suitable for use in IPM programmes to control aphids in pepper crops, as their diet consists mainly of aphids that attack pepper plants. In addition, these predators can take advantage of the agricultural matrix by feeding on alternative prey in the absence of aphids.
