RENTERIA, Laura  and  CANTU, César. El efecto de Tegeticula yuccasella Riley (Lepidoptera: Prodoxidae) sobre la fenología reproductiva de Yucca filifera Chabaud (Agavaceae) en Linares, N.L., México. Acta Zool. Mex [online]. 2003, n.89, pp.85-92. ISSN 2448-8445.

We registered the phenology (flowering, fruiting) and evaluated the effect of Tegeticula yuccasella Riley (Lepidoptera:Prodoxidae) on seed production of Yucca filifera Chabaud (Agavaceae). Yucca filifera flowered only once during 1998, from February to May, with peak flowering in March-April. The moth exhibited a 67% of pollinating efficiency and 3.8% of seed mortality by larvae. The highest density of T. yucassella adults was registered in March, coinciding with highest peak of Y. filifera flowering.

Keywords : Tegeticula yuccasella; Yucca filifera; Obligate Mutualism; Seed Predation.
