Diglyphus Isaea
Type: Parasitic wasp.
How it works: The wasp lays its eggs next to the
leafminer larvae, damage ceases immediately as the
larvae are paralysed. The wasp parasite larvae then feed
on the leafminer larvae. Adult females kill and feed
directly on small leafminer host larvae that are too
small to support a developing parasite larva.
Species controlled: Liriomyza (Tomato Leafminer) and
Phytomyza (Chrysanthemum Leafminer).
DIGLYPHUS ISAEA
PARASETIC WASPS 250 PER CONTAINER
£32.50
When to use: Ideal for use from mid-February in heated
crops and April in unheated crops. Establishment will
only occur if the wasp is released when sufficient
numbers of reasonable sized larvae are present within
the crop.
Rates of use: 1 wasp per 1 m2 every week for 3 to 4
weeks.
Feltiella Acarisuga Purpae
Type: Spider mites
How it works: Red or Two-Spotted Spider-Mites
(Tetranychus urticae) feed by puncturing cells and
draining the contents, producing a characteristic yellow
speckling of the leaf surface. They also produce silk
webbing which is clearly visible at high infestation
levels. At very high infestation levels, reddish-brown
masses of mites can be seen hanging from the tips of
leaves. When populations of spider mite are this high,
the pest can be transferred accidentally to clothing, and
spread around the crop by workers.
