What does MICROTERYS NIETNERI look like? 

Female parasitoids are about 2 mm in size and yellow-brown with a clear black and white band pattern on the wings and antennae. The males are black and a lot smaller than females. Parasitized brown soft scales can be recognized by one or multiple dark rings around the parasitoid larva below the cover of the soft scaleThe rings are the excrements produced by young parasitoid instars that grow within the soft scale body. The young parasitoids will emerge from a hole at the end of the pupae.

How does MICROTERYS NIETNERI work? 

The parasitoid MICROTERYS NIETNERI parasitizes small and large stages of brown soft scales. Depending on the soft scale size, females deposit one or several eggs in a host. A maximum of seven young parasitoids can emerge from one soft scale. The new generation of parasitoids will look for hosts to use for oviposition and repeat the cycle. Adult parasitoid feed by puncturing younger soft scales stages. This kills young soft scales and is called host feeding. 

When can MICROTERYS NIETNERI be applied? 

MICROTERYS NIETNERI can be used in greenhouses and indoor plantings to control brown soft scale (Coccus hesperidum). Other soft scales can be parasitized but to a much lesser extent. The minimum temperature is 18 ⁰C. Consider multiple introductions. The product is sensitive to several chemical pesticides. Ask advice for deployment strategies.
