- 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,
1
H 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-speci
fi
c 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 sec-
ondary 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.
