Sciarid Fly

A The adult flies are commonly found making short hops over the compost surface. Adults can spread fungal diseases but most damage is caused by the larval stage feeding on plant roots making them vulnerable to disease infections such as Pythium and other damping off diseases. 

Sciarid Fly Control Products

Hypoline  Hypoaspis miles  
A predatory mite which feeds on sciarid fly larvae and other 'soil' pests including springtails, thrips pupae and root mealybug. At night they move a short distance up, on to the plant foliage and will feed on mealybug and other soft bodied prey. Mites are very mobile and soon distribute themselves throughout the crop. Adults are reported to live for several months and survive up to 50 days without food, making them ideal in situations of very low pest populations.

Controls Bradysia spp. and many other insect or mite pests.

Introduce into most growing media including artificial substrates. Use as a preventative or at the first sign of sciarids. Requires a minimum temperature of 12oC. 

Exhibitline Sf  Steinernema feltiae  
Nematodes swim freely through moist compost (but they can drown if waterlogged), they are attracted to insect larvae and enter the body where a pellet of bacteria is released that kills the pest organism.

Controls Bradysia spp. and other compost / soil living pests such as larvae / pupae where nematodes can enter the host body. Can also be used as a foliar spray for Western Flower Thrips, leafminer and scale insect control.

Use as a curative treatment or programmed application for each batch of plants. The temperature range is 12 to 25°C. 

Staphyline  Dalothia coriaria   
Adults and larvae of a Staphylinid beetle. 2-3mm rove beetle feeds on the larvae and adults of a range of growing media pests. Controls
sciarid and shore flies. The effective temperature range is 12-35oC.
