Aphytis melinus is a parasitic wasp that attacks and kills hard scale.
Description
Aphytis melinus will parasitize several species of armored scale such as California red scale, latania scale, San Jose scale and oleander scale. Aphytis feeds on and oviposits in immature scales, preferring virgin adult female scales. This beneficial insect is very effective as a natural enemy because it reproduces more quickly than its prey.
Aphytis can be used outdoors for fruits, nuts and ornamental crops, as well as in greenhouses and interiorscapes. Scale can be quite challenging to control, but using Aphytis as an organic pest control will help reduce the use of harmful pesticides.
Aphytis are sensitive to many pesticides and it is important to check for pesticide residues before releasing these biocontrol agents. Be sure to consider secondary effects of a pesticide before using them in any crop where Aphytis are present. Ant control is also important where Aphytis are present because ants will disrupt the ability of the parasites to oviposit.
Rates and Release Instructions
1-6+ per square foot of crop canopy, bi-weekly or as needed.
To release Aphytis, leave container open and on its side in a tree or other crop, or walk through infested area and gently wave the container in the air, allowing the insects to fly out. Aphytis is active between 55-95°F.
Release parasites on the shaded side of trees. Release parasites every fifth to sixth tree every fifth to sixth row starting at a different row each release.
For use in greenhouse or interiorscape IPM programs. Release at dusk or when windows are covered so that the parasite finds infested plants more quickly.
