Health and environmental risk assessment of the larvae Chrysoperla Carnea for use as a plant protection product

  • 1. Norwegian Scientific Committee for Food Safety

Description

Gulløyelarver (green lacewing larvae, Chrysoperla carnea) is a product for biological control. The application is for use against aphids in green-houses and tunnels. Gulløyelarver was used in Norway from 1985-1993. An assessment in 2001 concluded, however, that the use of products with Chrysoperla carnea could represent an environmental risk since it was not known if the species in the products were the same as the ones with natural occurrence in Scandinavia.
In this regard, The Norwegian Food Safety Authority would like VKM to perform an assessment of possible risks related to health and environment in light of possible new data. The larvae of Chrysoperla carnea have hollow jaws through which they can inject digestive enzymes into their prey. In contact with humans, the larvae are capable of delivering painful bites which may cause local swelling. Such bites are, however, not considered dangerous, and can be avoided with preventive measures. 
Allergic asthma and rhinoconjunctivitis has been reported in persons working in the production of biological agents with Chrysoperla carnea, but it is the opinion of VKM that such effects are not likely to be relevant for users of the agents.Chrysoperla carnea is polyphagous and cannibalistic. They prefer aphids, but may also consume other insects and mites. It is, however, the opinion of VKM that the environmental risk from this will be minimized in greenhouses and tunnels where the release will be in a contained environment and directed against aphid colonies. Chrysoperla carnea may establish in the greenhouse and plastic tunnels and may also possess the ability to disperse and survive in the field. However, it is the opinion of VKM that the direct and indirect effects of this are at most moderate, although it cannot be completely excluded that Chrysoperla carnea species in the products might also have properties that have not been reviewed.
