Abstract

SevenLymantria spp. viruses from widely separated sources were used in a screening test for virulence. Laboratory data show thatLymantria dispar L. cytoplasmic-polyhedrosis virus of Japan, and the nuclear-polyhedrosis virus of Connecticut (U.S.A.) are more virulent than other five viruses when tested on the larvae of the gypsy moth. The nuclear-and cytoplasmic-polyhedrosis viruses ofLymantria fumidaBtl. were also infectious forL. dispar larvae.

Résumé

On a comparé au laboratoire la virulence de 7 souches différentes de virus des polyédroses nucléaire et cytoplasmique isolées deLymantria spp. Les essais effectués par contamination de la nourriture montrent que les chenilles deLymantria dispar L. sont sensibles à tous les virus employés. Les données permettent d’établir que la souche américaine de virus de la polyédrose nucléaire et la souche japonaise de virus cytoplasmique deL. dispar sont les plus virulentes.
