“…Indeed, trichomes affect natural enemies either by direct contact or indirectly by positively affecting the phytophagous prey insect (e.g. Simmons et al 2003;Oku et al 2006). However, interactions between plant surfaces and hoverfly aphidophagous predators have previously received little attention.…”

Trichome-based tomato resistance offers the potential to reduce pesticide use, but its compatibility with biological control remains poorly understood. We evaluated Episyrphus balteatus De Geer (Diptera, Syrphidae), an efficient aphidophagous predator, as a potential biological control agent of Myzus persicae Sulzer (Hemiptera, Aphididae) on trichome-bearing tomato cultivars. Episyrphus balteatus' foraging and oviposition behavior, as well as larval mobility and aphid accessibility, were compared between two tomato cultivars (Lycopersicon esculentum Mill. 'Moneymaker' and 'Roma') and two other crop plants; broad bean (Vicia faba L.) and potato (Solanum tuberosum L.). Hoverfly adults landed and laid more eggs on broad beans than on three species of Solanaceae. Hoverfly larval movement was drastically reduced on tomato, and a high proportion of hoverfly larvae fell from the plant before reaching aphid prey. After quantifying trichome abundance on each of these four plants, we suggest that proprieties of the plant surface, specifically trichomes, are a key factor contributing to reduced efficacy of E. balteatus as a biological agent for aphid control on tomatoes.

“…First, trichomes can provide major resistance against a number of herbivorous arthropods like aphids (Farrar and Kennedy 1991;Simmons et al 2003), but can also interact directly or indirectly with their natural enemies (Kennedy 2003). The resulting effects might be positive (increased proliferation, decreased cannibalism) (e.g.…”

“…Of all glandular trichomes analyzed, this gland is both of low abundance (Simmons et al, 2003) and the least characterized, due not only to its scarcity but also to its general physical properties. Located in close proximity to the epidermis, this glandular trichome consists of a small multicellular glandular head situated on a short, single-celled stalk, making it very difficult to isolate.…”

Glandular trichomes play important roles in protecting plants from biotic attack by producing defensive compounds. We investigated the metabolic profiles and transcriptomes to characterize the differences between different glandular trichome types in several domesticated and wild Solanum species: Solanum lycopersicum (glandular trichome types 1, 6, and 7), Solanum habrochaites (types 1, 4, and 6), Solanum pennellii (types 4 and 6), Solanum arcanum (type 6), and Solanum pimpinellifolium (type 6). Substantial chemical differences in and between Solanum species and glandular trichome types are likely determined by the regulation of metabolism at several levels. Comparison of S. habrochaites type 1 and 4 glandular trichomes revealed few differences in chemical content or transcript abundance, leading to the conclusion that these two glandular trichome types are the same and differ perhaps only in stalk length. The observation that all of the other species examined here contain either type 1 or 4 trichomes (not both) supports the conclusion that these two trichome types are the same. Most differences in metabolites between type 1 and 4 glands on the one hand and type 6 glands on the other hand are quantitative but not qualitative. Several glandular trichome types express genes associated with photosynthesis and carbon fixation, indicating that some carbon destined for specialized metabolism is likely fixed within the trichome secretory cells. Finally, Solanum type 7 glandular trichomes do not appear to be involved in the biosynthesis and storage of specialized metabolites and thus likely serve another unknown function, perhaps as the site of the synthesis of protease inhibitors.Trichomes are epidermal structures widely conserved across the plant kingdom (Kim and Mahlberg, 1991;Wagner, 1991;Alonso et al., 1992;Yu et al., 1992;Kolb and Muller, 2003;Valkama et al., 2003;Giuliani and Bini, 2008). These structures perform important biological functions, such as discouraging herbivory, attracting pollinators, and maintaining a boundary layer (Nihoul, 1993;Van Dam and Hare, 1998;Kennedy, 2003;Moyano et al., 2003;Simmons and Gurr, 2005;Liu et al., 2006;Horgan et al., 2007;Gonzalez et al., 2008;Romero et al., 2008;Nonomura et al., 2009;Kang et al., 2010). Many of these functions are the result of the specialized nature of glandular trichomes (glands) as sites for the synthesis and storage of biologically active specialized metabolites (Alonso et al

“…[5][6][7][8][9][10][11] However, host plant phenotype plays a crucial role in how herbivorous arthropods interact with entomophagous arthropods. 12 Some studies reveal no effect of trichome phenotype or density on performance of natural enemies of herbivorous insects.…”
