Laboratory screening supports the selection of sesame (Sesamum indicum) to enhance Anagrus spp. parasitoids (Hymenoptera: Mymaridae) of rice planthoppers

► Little is known about how to promote biological control in rice crops. ► Anagrus spp. parasitoids are known to attack rice planthoppers, serious pests. ► Olfactometer studies showed which flowers attract and which repel two Anagrus spp. ► Sesame nectar improved longevity, fecundity and handling time in Anagrus nilaparvatae. ► Sesame sown on rice bunds could improve management of rice planthopers.
