Macrolophus pygmaeus

Adult females are 3-3,6 mm in size, males are somewhat smaller. The bugs are bright green coloured. With adults the first antennal segments are dark. They have a dark line on their head just behind the big dark eyes. Young nymphs, first and second stages are yellow-green.

Mode of Action:

The bugs prefer whitefly as their prey. All stages of whitefly are being preyed upon but they prefer the younger ones as well as eggs. The bugs pierce their prey and suck them out. An adult predatory bug may consume an average of 2-5 adult whiteflies, 15-20 pupae or 30-40 larvae. Since Macrolophus also feeds itself from plant materials some minor damage symptoms may occur in young plants due its feeding activity. The proces of building a population is slowly but when Macrolophus is settled in a crop it sill stay there for a rather long time.


Is being used in greenhouse crops against whitelfy but also spidermites, thripses and egg of tomato leafminer (Tuta absoluta) are on its menu. Apart from that it preys upon aphids and leafminer-larvae. For home & garden use we have a special product MIRIMIX, a small packaging with Macrolophus pygmaeus. Consider multiple introductions. The product is sensitive for chemical pesticides. In some crops Macrolophus may cause some damage, mainly to flowers. Ask advice for proper introduction strategy.


  • especially effective in crops with soft, hairy leaves
  • sucked empty, dead larvae with remarkable small sucking hole remain as a result of feeding of the bugs
  • population build-up takes some time
  • may survive by plant feeding
  • additional food (ENTOFOOD) shortly after start of introductions may be useful for population build-up
  • after some time the number of fast moving green nymphs will increase
