Extracts from fruits and leaves of Melia azedarach were tested for repellent and insecticidal properties against eggs and nymphs of Triatoma infestans, the vector of Chagas disease. Unripe fruit extract was highly repellent for first and fourth instar nymphs. Ripe fruit had a weaker effect while leaves were ineffective. No effects on egg hatching, nymph survival or development time were detected, but first instar nymphs reared in contact with extract treated refuges were significantly smaller than controls after moulting.
