Info:
Leafminers puncture holes in the leaves to feed on plant juice and/or to deposit an egg in it. The larvae that follow chew mines through the leaf. The damage can mount up considerably. The parasitic wasp Diglyphus isaea is an efficient biological control measure of this pest.
 User Instructions:
  • Diglyphus isaea can be introduced as soon as 1 mine per plant is observed.
  • When there is a leafminer infestation, samples of the leaves should be tested to determine the percentage of leafminers parasitised by naturally occurring parasites and predators. Depending on the results, a specific strategy for each crop has to be determined. Consult the Biobest introduction scheme concerning the number of Diglyphus isaea to be introduced.
  • Parasitic wasp can be stored for a short while. Store the tubes horizontally in a cool (6-10°C, 42.8-50°F) and dark place.
  • Distribute the parasitic wasps equally in the vegetation. Unscrew the tube, walk around in the greenhouse with the open tube and make sure that the parasitic wasps leave the tube. When most of them have left, put the bottle somewhere in the greenhouse so that the last wasps can also fly in the vegetation.
  • Take samples of leaves every 2-3 weeks in order to check the parasitation.
Note: Several pesticides have a negative effect on Diglyphus isaea. Please be careful when controlling diseases and other pests. Consult Biobest's list on side-effects of pesticides on beneficials organisms.
