|125ml 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.
Calibrated to yield 250 adults
Ventilated cap for optimum humidity
Preventative control of large aphids Aulacorthum solani and Macrosiphum euphorbiae
Adults begin to emerge in transit ready for action
Sugar-water feeder ring ensures adult survival
Do not keep the container closed whilst waiting for mummies to hatch as this may reduce the percentage hatch rate. Release weekly at low rates as winged aphids appear in the crop. If colonies become established, make localized hotspot treatments or intervene at the economic threshold with a selective aphicide (e.g. 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 of adults and mummy formation.
