Aphid deterrence by glucose esters in glandular trichome exudate of the wild tomato,Lycopersicon pennellii

Abstract: Settling of the potato aphid,Macrosiphum euphorbiae, on feeding membranes was deterred by methanolic leaf rinses ofLycopersicon pennellii, or of its F1 with tomato,L. esculentum. The active compounds in theL. pennellii rinsates were identified as 2,3,4-tri-O-acylglucoses bearing short to medium chain length fatty acids. These compounds are localized in the glandular exudate of the type IV trichomes and may accumulate to levels in excess of 400 μg/cm(2). In choice assays, purified glucose esters fromL. pennelli… Show more

“…Plantas com altos teores de AA foram resistentes à mosca branca Bemisia argentifolii Bellows & Perring (Homoptera: Aleyrodidae) (Liledl et al, 1995;Maciel, 2008;Resende et al, 2009) e aos ácaros Tetranychus spp (Saeidi et al, 2007;Maciel, 2008;Pereira et al, 2008;Resende et al, 2008) e tiveram confirmada sua resistência à traça Tuta absoluta (Meyrick, 1917) (Lepidóptera: Gelechiidae) (Resende et al, 2006) em gerações segregantes. Tal fato se reveste de especial importância, pois embora a resistência a pragas em tomateiro mediada por AA seja bem documentada (Goffreda et al, 1989;Juvik et al, 1994;Liedl et al, 1995;Gonçalves et al, 2007;Resende et al, 2006Resende et al, , 2008Saeidi et al, 2007;Maciel, 2008), ainda não estão disponíveis, no mercado, tomateiros comerciais com níveis satisfatórios de resistência.…”

“…Sua presença também foi identificada em outras espécies do gênero Lycopersicon, bem como em outros gêneros da família Solanaceae, inclusive Solanum, Nicotiana e Datura (Severson et al, 1985;King et al, 1990;Shinozaki et al, 1991). Esse grupo de fitoquímicos pode atuar de modo a impedir a oviposição e a alimentação ou, ainda, a exercer efeito deletério no desenvolvimento de determinadas fases dos artrópodos-praga (Goffreda et al, 1989;Liedl et al, 1995;Resende et al, 2002aResende et al, , 2006Baldin et al, 2005).…”
