What does SPIDEND look like? 

SPIDEND contains the gall midge Feltiella acarisuga. Adult midges are pink-brown, inconspicuous with some light hairs on wings and the body. They are about 2 mm in size. The male antennae are longer and hairier than female antennae. The eggs are light yellow, banana-shaped and translucent. Eggs are deposited on the underside of leaves where spider mite damage occurs. The color of the larvae depends on the body content: orange, yellow or red. The cocoon is white and is often found next to the leaf vein. Killed spider mites shrivel and turn brown or black. 

How does SPIDEND work? 

The gall midge larvae feeds on all spider mite stages. They attack prey, paralyze them and feed on their contents. Adult midges do not eat spider mite, but instead survive on a diet water and sugar. They look for spider mite colonies where they can deposit their eggs and are mostly active at night. Feltiella acarisuga is especially good in controlling local, large spider mite populations. Larvae can eat about 30 spider mites or 80 spider mite eggs a day. 

When can SPIDEND be applied? 

SPIDEND is used in greenhouses and indoor plantings to control the two-spotted spider mite (Tetranychus urticae), mainly when present in hot spots. SPIDEND is suitable for a combination with the predatory mite Phytoseiulus persimilisHigh humidity is needed to ensure the effectiveness of the gall midge. Consider multiple introductions. The product is sensitive to several chemical pesticides. Ask advice for deployment strategies.
