Abstract

—Silkworm larvae infected transovarially with Nosema bombycis were fed with an aqueous suspension of Bavistin (50% carbendazim w/w) at 2 and 3% concentrations. The treatments increased the survival of worms and reduced the pebrine infection in the lot significantly, although complete elimination of infection was not observed. Significant beneficial effects of the treatments at 2 and 3% were also observed with respect to larval, cocoon and cocoon shell weights and cocoon to shell ratio. However, treatments with Bavistin at 4% concentration produced an adverse effect on cocoon characters.

Résumé

—Les chenilles du ver-à-soie infectées par voie transovarienne avec Nosema bombycis, ont été nourries avec une solution aqueuse de Bavistin (carbendazim 50%, w/w) aux concentrations de 2 et 3%. Les traitements ont augmenté la survie des vers et réduit significativement l’infection à pébrine au sein du lot, quoiqu’une élimination complète de l’infection n’ait pas été observée. Des effets bénéfiques significatifs du traitements ont été aussi notés à 2 et 3 % à l’égard du poids de ver, du cocon et de la carcasse du cocon et à l’égard du ratio cocon/carcasse. Cependant, le traitement avec du Bavistin à la concentration de 4% a produit un effet adverse sur des caractères du cocon.
