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 caliginosus 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 caliginosus 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.
