abstract = {Plants attacked by herbivorous insects release chemical
signals that attract natural enemies of the herbivores to
the damaged plants. Feeding of Spodoptera exigua larvae on
the lower leaves of cotton (Gossypium hirsutum L.) for
multiple feeding periods of 9-12 h with a 12 h, interval in
between when the caterpillars are removed overnight, will
induce a systemic release of volatile compounds that is
comparable to the volatiles released in response to
continuous feeding damage on the lower leaves for several
days. The systemic volatile release in response to herbivory
can be mimicked by mechanically damaging the lower leaves
and applying caterpillar oral secretion to the injured
leaves over 4 days. Cotton plants that are only mechanically
damaged systemically release significantly less beta-pinene,
myrcene, (Z)-3-hexenyl acetate, (E)-beta-farnesene and
(E,E)-alpha-farnesene after 4 days compared to plants
damaged mechanically with application of caterpillar
regurgitant. However, multiple 9-12 h mechanical damage
alone induces a significantly higher systemic release of
(Z)-3-hexenyl acetate, myrcene, (E)-beta-ocimene, and
(E)-beta-farnesene after 4 days compared to undamaged
control plants. This indicates that multiple mechanical
damage alone cannot mimic completely the response induced by
mechanically injuring the leaves and applying caterpillar
regurgitant. A specific elicitor in the regurgitant of the
caterpillar enhances the amount of several systemically
released volatiles. Thus, the systemic release of volatile
compounds by herbivore-damaged cotton plants appears to be
regulated by at least two different mechanisms.},
