A research team from the Agroforestry Technology Research and Development Centre recorded that infestation by the caterpillar pest Graphium agamemnon on manglid (Magnolia champaca) was higher in monoculture than in agroforestry. Infestation in monoculture reached 39.25%, compared with 25.75% in agroforestry. The study was published in Jurnal Wasian in 2018.

In addition to measuring infestation, the team identified the natural enemies of the pest. Larvae of G. agamemnon were found to be attacked by the parasitoid Diaparsis sp. The parasitisation rate in monoculture was recorded at 55.00%, while in agroforestry it was higher, at 66.67%.

These findings are important for farmers and forest managers who plant manglid. Agroforestry not only reduces the intensity of pest infestation but also supports the work of natural parasitoids. Thus, pest control can rely on natural enemies and reduce dependence on pesticides.
