Wasps chalcid

PREVENTIVE. Take care not to harm the chalcid wasps, as they achieve a very high degree of parasitization. 

ENEMIES. The most important beneficial insects are braconid and chalcid wasps. 

ENEMIES. The most important enemies of the leaf-mining moths are bra-conid and chalcid wasps. These are able to keep all the leaf-mining moth species except Leucoptera scitella below the commercial damage threshold. 

Enemies which are frequently mentioned are fungi, chalcid wasps and nematodes, which attack and parasitize the beetles in their winter hiding-places.

ENEMIES. The most important enemies of the tortrix moths are ichneumon, chalcid and braconid wasps. In many orchards the degree of para-... 

CONTROL. The tortrix moths that feed on fruit have become less of a problem in integrated and especially in organic fruit production. Very high rates of parasitism by chalcid and braconid wasps can be achieved hy conservation of beneficial insects. 

PREVENTIVE. Conservation of beneficial insects (chalcid and braconid wasps).
