Orders due Wednesday morning for shipment the following week. 

Description

Dacnusa sibirica are parasitic wasps for leaf miner larvae. Adults are small, dark, non-stinging wasps 2-3mm in size, females lay their eggs in leaf miner larvae which serves as a host for their offspring.

Dacnusa can discern between non-parasitized and parasitized larvae, increasing the rate and effectiveness of their parasitization. This beneficial insect offers good control in cooler conditions, making them suitable for Spring and Fall releases. Organic pest control without using harmful pesticides. 

Parasitizes leaf miners at low prey densities and at cooler temperatures. Use Dacnusa when temperatures are below 68F and support with Diglyphus when temperatures are above 68F. Target crops are cannabis, tomato, gerbera and chrysanthemum. 

Life Cycle

Adults live for about 2 weeks. During this period, a female can lay up to 90 eggs, which hatch within 4 days of laying. Dacnusa larvae mature inside the Leaf Miner larvae, the total development time from egg to adult is about 2 weeks at 72°F.
