Abstract
Spraying of water suspensions ofNeoaplectana bibionis Bovien on established blackcurrant bushes infested with currant borer moth,Synanthedon tipuliformis (Clerck), resulted in up to 90% mortality of larvae. Mortality was influenced by dosage, water volume, age of wood and time of application. Some nematodes migrated to new tunnels resulting in an increase in parasitization with time. No phytotoxicity was observed on any of the treated bushes. The cost of nematode application may be comparable to that of insecticides without any of the associated problems.
Resumé
La pulvérisation de suspensions aqueuses deNeoaplectana bibionis Bovien sur des cassissiers attaqués par la sésie du cassis,Synanthedon tipuliformis (Clerck) provoque jusqu'à 90% de mortalité des larves. Cette mortalité est influencée par la quantité de nématodes, le volume d'eau, l'âge du bois et l'époque d'application. Des nématodes migrent dans les nouvelles galeries, ce qui augmente le taux de parasitisme avec le temps. On n'a observé aucune phytotoxicité sur les touffes traitées. Le coût du traitement avec les nématodes peut être comparable à celui des insecticides sans aucun des problèmes associés à ceux-ci.
