Secuencia de aparición de parasitoides en poblaciones larvarias de lepidópteros que atacan al algodón en el Valle del Guadalquivir

OBALLE, R.; VARGAS-OSUNA, E.; LYRA, J. R. M.; ALDEBIS, H. K. y SANTIAGO-ALVAREZ, C , 1995: Presence of parasitoids in lepidopteran species larval populations causing damages on cotton in Guadalquivir Valley. Bol. San. Veg. Plagas, 21(4): 659-664. During the years 1992, 1993 and 1994, eggs and larvae of phytofagous lepidopteran species were collected from cotton fields in Guadalquivir Valley to know the parasitoid species and their seasonal relationships with their hosts. Heliothis armigera (Hiibner) was the most abundant species, then Pectinophora gossypiella (Saunders), Earias insulana (Boisduval), Spodoptera littoralis (Boisduval) and S. exigua (Hiibner). The braconid Cotesia kazak Telenga and the encyrtids were the most important parasitoid species affecting to H. armigera and P. gossypiella larval populations, respectively. The other species had an occasional presence.
