Abstract
The fungusVerticillium lecanii (Deuteromycétes) was mass cultured on an inexpensive substrate (grain seeds or bread cubes) and, after final processing was used, either undiluted or diluted to a 10 per cent concentration, as a preparation againstCoccus hesperidum in the glasshouse. With both concentrations an 85–100 per cent mortality was achieved within 3 weeks. In addition to this typically parasitic fungus, tests were performed with the fungusAspergillus candidus, which proved to be equally effective.
Résumé
Le champignonVerticillium lecanii (Zimm.) Viég. a été cultivé en masse sur des grains de blé ou des morceaux de pain. Les spores ainsi obtenues ont été utilisées par saupoudrage ou arrosage contre les cochenillesCoccus hesperidum L. en serres. En employant soit une préparation concentrée, soit une préparation à 10% une mortalité de 85–100% a été obtenue en 3 semaines. Le champignon non pathogène,Aspergillus candidus, fut également étudié et s'est montré très efficace contre la cochenille.
