Effective against greenhouse thrips
What does THRIPOCTENUS JAVAE look like?
The adult parasitoids are ± 0.6 mm in size. They have a black head and black thorax. The abdomen is yellow with dark spots and the legs and antennae are also yellow. Male THRIPOCTENUS JAVAE do not occur. Thrips larvae that are parasitized by this wasp change shape. When the parasitic wasp larva, which grows up in the thrips larva, pupates, it turns black. The shape of the parasitic wasp is already somewhat recognizable in the cocoon that is created. These cocoons can often be found in groups at the bottom of the leaves. The parasitic wasp comes out by tearing open the cocoon.
How does THRIPOCTENUS JAVAE work?
The product THRIPOCTENUS JAVAE contains parasitoid pupae, which hatch after several days. The parasitoids prefer to parasitize smaller thrips larvae. A female wasp deposits a single egg per thrips larvae. THRIPOCTENUS JAVAE is less effective in the presence of ants.
When can THRIPOCTENUS JAVAE be applied?
THRIPOCTENUS JAVAE is especially effective against the greenhouse thrips (Heliothrips haemorrhoidalis) commonly found in zoos and botanical gardens. Other thrips species, such as the banded greenhouse thrips (Hercinothrips femoralis), are parasitized to a much lesser extent. The cards with the pupae of the parasitic wasp can be hung in the plant. THRIPOCTENUS JAVAE can also be applied in greenhouses and other indoor plantings. Be aware of multiple repeat introductions. The product is sensitive to various chemical crop protection agents. Ask advice for deployment strategy.
