Abstract

The damage potential of the spider mite Tetranychus Indent Zacher was studied on 20-65-day-old seedlings of four eggplant Solanum melongena varieties: Madurai (MDU1), Coimbatore (CO1), Annamalai and Panruti at introduction levels of 2, 5, 10 and 15 mites/leaf. The average seedling mortality among varieties was lowest at the introduction level of two mites and maximum at the introduction level of 15 mites/leaf. The overall seedling mortality was 23% when the four levels of mite population were introduced on 20-day-old seedlings, and only 14% on 30-day-old seedlings. Among the different varieties, the MDU1 seedlings recorded higher mortality (1.6%) and Panruti the lowest (0.3%). The percentage losses in total plant height, number of leaves, number of flowers and fruits and fruit weight due to mite attack were highest (37–50%) in MDU1 and lowest (7–11%) in the variety Panruti. The other two varieties CO1 and Annamalai were found to be intermediate between Panruti and MDU1. The inoculated mites at different levels multiplied greatly on the variety MDU1 followed by CO1, Annamalai and Panruti. The extent of damage was higher in 35-day-old plants, when mites were introduced on 35- and 65-day-old seedlings. Therefore, the variety Panruti is recommended for cultivation in the study area in view of its resistance to T. Indent.

Résumé

On a étudié les dégâts potentiels de l’acarien Tetranychus ludeni Zacher sur des plantules d’ aubergine Solanum melongena, âgées de 20 à 65 jours, sur les quatre variétés Madurai (MDU1), Coimbatore (CO1), Annamalai et Panruti et pour des niveaux d’infestation de 2, 5, 10 et 15 acariens/feuille. La mortalité moyenne des plantules est minimale pour 2 acariens/feuille et maximale pour 15 acariens/feuille. La mortalité totale des plantules est de 23% sur des plantules âgées de 20 jours et seulement de 14% sur des plantules âgées de 30 jours. Parmi les différentes variétés, on a enregistré la plus forte mortalité (1.6%) sur les plantules de MDU1 et la plus faible (0.3%) sur les plantules de Panruti. Les pourcentages de pertes en taille, nombre de feuilles nombre de fleurs et fruits et poids des fruits sont maxima (37–50%) sur MDU et minima (7–11%) sur Panruti. Sur les deux autres variétés, CO1 et Annamalai, on a enregistré des pertes intermédiaires. Les dégâ ts sont maxima sur les plantes âgées de 35 jours, lorsque les acariens ont été inoculés sur des plantules âgées de 35 à 65 jours. En conséquence, la culture de la variété Panruti est recommandeé dans la zone d’étude compte tenu de sa résistance à T. ludeni.
