Abstract

Population of Spodoptera litura F. were monitored through pheromone-baited traps during the rainy season 1988 and 1989 in groundnut fields in relation to oviposition on leaves. Four peaks of adult catches were recorded. First and second peaks were smaller and caused no threat to crop. Third peak was observed at the pegging and pod-initiation stage during first week of September and coincided with the greatest oviposition on leaves. The fourth peak was greatest and occurred between 40th and 43rd standard week. However, no oviposition was recorded on groundnut during this period. The moths possibly dispersed and/or migrated to other areas with crops at an appropriate stage of susceptibility.

Résumé

Les prises des papillons mâles de Spodoptera litura (Fabricius) dans les pièges à phéromone et leur rapport avec la ponte dans un champs d'arachide à Pantnagar, en Inde: La surveillance des populations de Spodoptera litura F. était effectuée à l'akte des pièges à phéromone dans un champ d'arachide au cours de ia saison pluviale 1988–1989. L'étude a porté sur leur rapport avec la ponte sur les feuilles. Quatre pics desprisesd'adultesont été enregistrés. Le premier et le deuxième pics étaient modérés et n'ont pas endommagé la culture. Le troisième pic était observe aux stades de formation de gynopnores et de gousses pendant la premiere semaine de septembre et a coincide avec la plus importante ponte sur les feuilles. Le quatrième pic était le plus important et a eu lieu entre la 40e et la 43e semaine type. Cependant, aucune ponte a été enregistrée sur l'arachide pendant cette période. Les papillons s'étaient probablement disperses et/ou migré à d'autres regions avec les cultures à un stade approprice de sensibllité.
