Abstract

Pathogenicity of the microsporidium Nosema fumiferanae (Thomson) in the obliquebanded leafroller, Choristoneura rosaceana (Harris), was evaluated in laboratory bio-assays. When consumed by first-, fourth-, or fifth-instar obliquebanded leafroller larvae, Nosema spores primarily infected the gut and Malpighian tubules. When 2000 spores per square millimetre diet surface were consumed by neonate, fourth-, or fifth-instar larvae, the N. fumiferanae caused 91, 24, and 5% mortality, respectively. Infection by N. fumiferanae had a delayed impact on the older larvae. Large numbers of spores were retained to the adult stage by obliquebanded leafrollers treated as fourth- or fifth-instar larvae.

Résumé

La pathogénie du microspore Nosema fumiferanae (Thomson) pour la tordeuse à bandes obliques, Choristoneura rosaceana (Harris), a été évaluée par des essais biologiques en laboratoire. Quand dévorée par les larves de la tordeuse à bandes obliques du premier, du quatrième et du cinquième stade, les spores de Nosema ont contaminé principalement l’intestin et les tabules de Malpighi. Quand les larves néonatales et celles du quatrième et du cinquième stades ont dévoré les régimes alimentaires ayant 2000 spores par millimètre carré de surface, N. fumiferanae a occasionné une mortalité de 91, 24 et 5%, respectivement. La contamination par N. fumiferanae a eu un impact différé pour les larves âges. Un grand nombre de spores a été retenu jusqu’au stade d’adulte par les larves de la tordeuse à bandes obliques, qui ont été traitées au quatrième ou au cinquième stade larvaire.
