What does MACROLOPHUS PYGMAEUS look like? 

The predatory bug MACROLOPHUS PYGMAEUS is used for the biological control of whitefly, spider mite, thrips and moths. The bugs are bright green with dark antennae bases and behind the large, dark eyes a dark line is visible. Adult females are 3-3,6 mm in size, males are somewhat thinner and smaller. Young nymphs are wingless and are yellow green in the first and second stage. In later stages they turn green like the adults. The bugs shave long, slim legs which are specially evolved for walking on hairy plant parts. This makes them suitable for application in ‘hairy’ crops like tomato and eggplant.

How does MACROLOPHUS PYGMAEUS work? 

This generalistic predatory bug consumes many different prey species but has a preference for whitefly. All whitefly species are preyed upon with a preference for eggs and larvae. The bugs puncture their prey and feed on their contents. An adult predatory bug can eat 2-5 adult whiteflies, 15-20 pupae or 30-40 larvae per dayMACROLOPHUS PYGMAEUS can sustain itself in absence of prey by feeding on plant saps. This plant sap feeding can sometimes cause damage in young plants. The population development is slow, but when established, MACROLOPHUS PYGMAEUS will be present for a long time. To support the establishment of this predatory bugan extra food source such as Ephestia or Artemia can be distributed in the crop.  

When can MACROLOPHUS PYGMAEUS be applied? 

MACROLOPHUS PYGMAEUS is used in greenhouses for the biological control of whitefly, but also spider mitesthripsbutterfly eggs and tomato leafminer (Tuta absoluta) are preyed upon. Furthermore, aphids and leaf-miner flies are also consumed.  

The predatory bug MACROLOPHUS PYGMAEUS is available as two different products: MIRICAL and MIRIMIX-PLUS. MIRICAL is supplied in bottles with 500 adults and is available for business customers.

For application in private greenhouses, a special product is available; MIRIMIX-PLUS. This contains a mix of 50 adults and nymphs of MACROLOPHUS PYGMAEUS and comes with Artemia feed to give the predatory bug a good start. Consider multiple introductions. The product is sensitive to several chemical pesticides.  In some crops MACROLOPHUS PYGMAEUS can cause damage, mainly in flowers. Ask advice for deployment strategies.
