Flowering, fruiting and fruit fall in groves of yellow chapote was tracked at two locations at different elevations over two years in Mexico. Fruit on and off the trees were sampled for infesting larvae. Simultaneously, traps set in the trees surveyed the adult mexfly population. All females were dissected for reproductive status. Peaks in adult population levels preceded and followed the peak in chapote fruit production.
