A 125 ml plastic bottle contains purified mummies in sufficient quantity to yield 250 adults of Aphidius ervi. This tiny braconid wasp will sting and parasitise larger aphids such as Aulacorthum solani and Macrosiphum euphorbiae as well as aphids such as Myzus sp, Sitobion sp., Schizaphis sp., Rhodobium sp., Acyrthosiphum sp and others.

Aphid Parasite

Release weekly at low rates as winged aphids appear in the crop. If colonies become established, make localised hotspot treatments or intervene at the economic threshold with a selective aphicide (eg pymetrozine, pirimicarb.) If aphids are suspected of transmitting virus or populations are high, use pymetrozine or pirimicarb (depending on local registrations in the crop) before releasing Aphidius ervi. Do not spray between release and mummy formation.
Use at the rate of 0.1-0.5 adult per sqm for preventative use. One 125 ml bottle is sufficient for 500-2500 sqm. Dose rate may be increased 5-fold for hot spots.
Open in the greenhouse. Walk round the area to be treated, holding the open bottle at a 45° angle, releasing the emerged adults into the air. Distribute the adults evenly over the area. Recap the bottle and store at greenhouse temperature until more adults have hatched. Repeat the distribution of adults daily for 2-4 days until most adults have emerged from the bottle. Finish by placing the open bottle in the greenhouse next to a plant in case more hatch. Can also be reared on banker plants.
Transport and store at 6-8°C.
Keep out of direct sunlight.
