Mango headspace volatiles trigger differential responses of the mango fruit fly and its parasitoids.

Before the introduction of (Hendel) to sub-Saharan Africa, (Walker) was economically the most important pest in mango farming. Its native natural enemy, the solitary parasitoid (Wilkinson), played a crucial role in bio-control, later complemented by the exotic parasitoids (Ashmead) and (Sonan) among Integrated Pest Management (IPM) systems. To understand the mango--parasitoid tritrophic interaction, we assessed the responses of the fruit fly and the three parasitoids to headspace volatiles from various mango conditions.

Electroantennogram and machine learning reveal a volatile blend mediating avoidance behavior by Tuta absoluta females to a wild tomato plant.

Tomato cultivation is threatened by the infestation of the nocturnal invasive tomato pinworm, Tuta absoluta. This study was based on field observations that a wild tomato plant, Solanum lycopersicum var. cerasiforme, grown in the Mount Kenya region, Kenya, is less attacked by T.
