Introduction

• make a hole in the paper in the lid on the beaker and put it on the rockwool slab or the soil

Remarks

Feltiella acarisuga should always be used in combination with the predatory mite Phytoseiulus persimilis (SPIDEX).

 

Appearance

Adults: midge of 2 mm long, pink-brown, long legs

Eggs: oblong, 0.1 x 0.25 mm in size, shiny, translucent

Larvae: 0.2-2 mm in size, orange-brown, occur in spider mite colonies

Pupae: are inside a white coccoon, occur mainly at the undersides of leaves, along the veins

 

Mode of action

Adult gall-midges search for spider mite colonies actively and deposit eggs next to the spider mites. The larvae that hatch feed on spider mite eggs and suck them empty. It takes one week for the eggs to develop to mature larvae. The pupal stage takes approximately one week.

 

Visual effect

Spider mites that are killed by the gall-midge shrivel up and become brown or black. Dozens of larvae can be found per spider mite infested leaf. White cocoons are clearly visible along the veins of the leaf.
