APHIDS UNDER GLASS |
Aphidoletes larva |
Adult Aphidius |
Aphids under glass can be controlled by parasitic wasps (we supply APHIDIUS
and PRAON) all the year round, and by predatory larvae of the midge APHIDOLETES
from spring to autumn. Although these biocontrols are native species, control
outdoors is less predictable as environmental factors such as heavy rain, predatory
birds, hyperparasitic wasps etc. will affect success. Aphids moult as they grow and the shed skins drop to the upper surface of the leaf below. These white skins can be confused with whitefly, for which a different control is needed. See the pictures on the whitefly page if in doubt. Amateur pack of 200 controls £8.50 incl. VAT Professional packs £3/100 + VAT (minimum order 300) |
