Abstract

Abscised fruits were more likely to contain predator larvae than were undamaged fruits. Larvae in abscised fruits were more likely to die than larvae in fruits still attached to the tree. Selective abscission of damaged fruits is viewed as an adaptive plant defense since 1) abscission reduces the plant's losses by terminating any further investment into a doomed propagule; 2) abscission may reduce the number of fruit predators that mature to attack future fruit crops. -from Authors
