title: Local phytochemical response of Musa acuminata × balbisiana Colla cv. 'Bluggoe' (ABB) to colonization by Sternorrhyncha.
abstract: The interaction of two Sternorrhyncha species, the banana aphid (Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae, Aphidinae)), vector of the banana bunchy top virus (BBTV), and the latania scale (Hemiberlesia lataniae Signoret (Hemiptera: Diaspididae, Diaspidinae)) with Musa acuminata × balbisiana Colla (ABB Group) 'Bluggoe' (Musaceae) was investigated by a combination of conventional and spatially resolved analytical techniques,1H NMR, UHPLC-MS, and matrix-free UV-laser desorption/ionization MS imaging. After infestation, the feeding sites of P. nigronervosa on the pseudostem and the exocarp of banana fruit developed a red tinge, in which tissue-specific accumulations of phenylphenalenones were discovered. Phenylphenalenones were also detected in the black mats of sooty molds growing on the banana aphid exudates and in the dorsal scales of H. lataniae. This suggests that although these secondary metabolites play a role in the reaction of banana plants towards attack by sucking insects, an aphid and an armored scale have established mechanisms to exude these metabolites before they deploy their deleterious effect.
