Abstract

Water suspensions of the entomogenous nematode, Steinernema feltiae Filipjev (“All” strain), were applied to the soil of caged microplot stands of canola, Brassica napus L. cv. Tower, colonized by overwintering adults of the crucifer flea beetle, Phyllotreta cruciferae (Goeze), at the rate of about 1 × 106 infective juveniles per 0.8 m2 soil surface. Single treatments, which were applied before and after the colonization, did not affect the flea beetle adults or their progeny as evidenced by the number of new generation adults that subsequently emerged from the soil. Bioassays with wax moth larvae, Galleria melonella (Linn.), showed that the infectivity of nematodes in the soil declined sharply within 6 days of treatment. High concentrations of the herbicide Treflan®, with which the soil was treated, did not affect the infectivity of the nematodes. Under the conditions of the test, S. feltiae appeared to have no potential as a biological control agent for the crucifer flea beetle.

Résumé

Des suspensions aqueuses du nématode entomopathogène Steinernema feltiae Filipjev (multisouches) ont été appliquées au sol de microparcelles grilladées de colza canola, Brassica napus L. cv. Tower, colonisées par les adultes hivernants de l’altise des crucifères Phyllotreta cruciferae (Goeze). Les suspensions étaient utilisées à raison d’environ 1 × 106 juveniles infectieux par 0,8 m2 de surface de terre. Un traitement unique appliqué avant et après la colonisation s’est révélé sans effet sur les altises adultes et sur leur descendance si l’on en juge d’après le nombre d’adultes de nouvelle génération sortis par après. Des dosages biologiques effectués sur la fausse-teigne de la cire Galleria melonella (L.) ont fait voir une chute brutale de l’infectivité du nématode dans le sol dans les 6 jours suivant le traitement. Des doses élevées de l’herbicide Treflan® n’ont pas eu d’effet sur l’infectivité du nématode. Dans les conditions d’exécution de l’essai, S. feltiae ne semble pas offrir de possibilités comme agent de lutte biologique contre l’altise des crucifères.
