Abstract

The insecticide diflubenzuron, Dimilin, was applied topically to the eggs of Tabanus triceps and Chrysops dispar. Mean per cent hatchability of these eggs at various concentrations ranging from 1 to 150 ppm were observed. The hatchability depended upon the age of the egg and increased with age. A minimal dose of 10 ppm of diflubenzuron caused 100% mortality (no hatchability) at the age of 48 hr in both species. The per cent hatchability was inversely proportional to the concentration of Dimilin. The larvicidal effect of Dimilin was also noted. Larval mortality (100%) was observed after 60 hr treatment. The larval mortality was directly proportional to the concentration of Dimilin. The results show that Dimilin has potential for controlling Tabanid vectors.

Résumé

L'insecticide diflubenzuron, le Dimilin a été déposé sur des oeufs de Tabanus triceps et Chrysops dispar. Le taux moyen du pourcentage d'éclosion de ces oeufs à des concentrations variées, allant de 1 à 150 ppm a été observé. La capacité à l'éclosion dépend de l'âge des oeufs et elle augmente à mesure que l'oeuf avance en âge. Une dose minimale de 10 ppm de diflubenzuron cause 100% de mortalité chez des oeufs âgés de 48 heures dans les 2 espéces. Le pourcentage d'eclosion est inversement proportionnel à la concentration de Dimilin. L'effet larvicide est également noté et une mortalité larvaire de 100% est observée après 60 heures de traitement. La mortalité larvaire est directement proportionnelle à la concentration de Dimilin. Les resultats montrent que le Dimilin est un insecticide potentiel, qui peut être utilisé pour contrôler les Tabanides vecteurs.
