El efecto de Tegeticula yuccasella Riley (Lepidoptera: Prodoxidae) sobre la fenología reproductiva de Yucca filifera Chabaud (Agavaceae) en Linares, N.L., México

摘要

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.
