Herbivore-Induced Plant Volatiles (HIPVs) are semiochemicals (natural signal chemicals mediating changes in behavior and development) plants produce after insect damage occurs which act to repel pests and attract their natural enemies.

"In essence, plants attacked by herbivores emit specific chemical signals. These are the ‘words’ of a complex language used to ‘warn’ other plants of impending attack and to recruit predatory/parasitic arthropods for ‘bodyguard’ services. Such plant ‘bodyguards’ respond to the language of plants in distress and benefit from the food/host resources available."[1]

In some varieties of plants, HIPVs are triggered before an insect attack actually occurs, when the adult insect merely lays an egg on the plant. This recruits predators to come even before the plant is damaged.[2][3][4][5] Scientists found that some maize open pollinated varieties (OPVs) of Latin American and African origin produced HIPVs in response to an insect laying an egg on thep lant, whereas standard commercial varieties did not.[5] "It is possible that the high selection pressure for other traits, e.g., yield, might have caused the loss of such valuable traits in commercial varieties."[6]

Discovery of HIPVs

This phenomenon was first demonstrated by Maurice Sabelis and Marcel Dicke in the Netherlands in a series of experiments on a bean plant-spider mite-predatory mite system.[7][8][9]

Examples of HIPVs

  • When caterpillars feed on corn plants, the corn plants produce HIPVs to attract parasitic wasps.[10]
  • When aphids lay eggs and feed on broad beans, the beans produce HIPVs to attract parasitic wasps.[11][12]

A study of six different varieties of maize infested with armyworms found the variety that emitted the most volatile chemicals emitted almost fifteen times more than the lowest emitting variety. The study concluded that "Herbivore-induced plant volatiles and/or correlates thereof contribute to reducing insect damage of maize plants through direct plant defence and enhanced attraction of parasitoids, alleged indirect defence."[13]

Uses of HIPVs

Use in Maize in Kenya

In Kenya, where maize is the staple crop, scientists found that maize produces the compounds ocimene and the nonatriene when herbivorous insects damage the plants. are semiochemicals produced during damage to maize plants by herbivorous insects[14][15] The chemical nonatriene attracted parasitic wasps which prey on the pest species (the stem borer).[16] Therefore, by intercropping maize with species like Molasses grass (Melinis minutiflora), which naturally produces ocimene and the nonatriene regardless of the presence of stem borers, farmers could both repel egg laying stem borer moths and attract parasitic wasps that prey on the stem borer even before any pest damage occurred.[17][18]
