Abstract
In laboratory assays, two Bacillus thuringiensis var. kurstaki preparations, HD-263a WP and HD-263c WP, were highly effective against larvae of the honeydew moth, Cryptoblabes gnidiella Millière (Lepidoptera: Pyralidae), especially against the first and second instars. Both preparations were more effective than DipelR WP at most concentrations tested. Two viral preparations, AcMNPV and Amorbia cuneana NPV, were ineffective.
Résumé
Dans les laboratoires, des essais de préparations de deux Bacillus thuringiensis var. kurstaki, HD-263a WP et HD-263c WP, ont été très effectives sur la larve de la mite, Cryptoblabes gnidiella Millière (Lepidoptera: Pyralidae), effectives surtout sur la première et seconde larve. Les deux préparations ont été très effectives, ainsi que les doses examinees, mieux qu’avec le DipelR WP. Deux préparations de virus, AcMNPV et Amorbia cuneana, n’ont pas été effectives.
