Introduction
- sprinkle material on clean rockwool slab (or on leaves)
- spread material thinly (maximum 1 cm thick) to enable easy movement of predatory bugs
Environmental conditions
At low temperatures Macrolophus pygmaeus develops very slowly.
Storage and handling
- storage after receipt: 1-2 days
- storage temperature: 8-10°C/47-50°F
- in the dark (bottle horizontally)
Remarks
- the use of Macrolophus pygmaeus in gerbera is not advised, because the predatory bug can cause damage to the flowers
- some growers of cherry tomatoes and small truss tomatoes were surprised by some fruit set problems. Some flowers per truss 'knuckled off' before setting. It turned out that these problems happened only in cherry tomato crops with a very high population of Macrolophus, absence of any prey and weak truss development.
Appearance
Adults: size 6 mm, green, slim, long legs and antennae, mainly in shoots and along stems
Eggs: invisible, in leaves and stems
Nymphs: yellowish-green to green, mainly on the underside of leaves
Mode of action
Adult predatory bugs and nymphs search actively for their prey, insert their sucking mouthparts and suck out the contents.
Visual effect
Reduction of pest population.
