How to use

Introduce Aphipar throughout the crop so that emerging Aphidius colemani adults can disperse and search for suitable aphid hosts.

Standard application rate: Apply 1–2 per m² per week.

When small aphid colonies are present: Increase the application rate to 5 per m² per week for 3 weeks.

Distribute the product throughout the treatment area, concentrating introductions around areas where aphid activity has been identified.

Monitor aphid populations regularly and follow the storage, handling and environmental guidance supplied with the product.

Specifications

Tech Comments Most crops can be infested with aphids. Damage is caused in three ways: sucking plant sap when feeding, excretion of honeydew leading to sooty mould and some species can transmit plant viruses leading to distortion and disfigured plant growth. Biological control with parasites, predators and fungal pathogens are available depending on crop and environmental conditions. There are a large number of aphid species and identification can be important when parasitic wasps are to be used. Depending on the species there can be alternate plant hosts. Winged forms develop under conditions of high density to migrate to alternate hosts. Resistance to some insecticides is a serious issue with some species.
Control It is particularly effective against round bodied aphid species such as Myzus persicae (peach-potato aphid) and Aphis gossypii (melon cotton aphid). The adult wasp inserts its egg into the aphid, a parasite larva develops killing the aphid, producing a characteristic goldenbrown papery 'mummy' An adult parasitic wasp later emerges through a round hole on the mummified aphid. The adult wasps also feed as a predator on aphids, killing one or more each day. The first mummies are noticed in the crop around 10-14 days after the first introduction. Most effective between 20 and 25°C. Effectivity is reduced at temperatures above 30°C.
