Macrolophus caliginosus

Macrolophus is a bug. The body of an adult individual is oblong, downy, light-yellow, 2.7–3.7 mm in length. The female lays eggs in the veins and the stakes of a leaf blade. Potential fertility is 140 eggs, but the real is 70–80 eggs.  An individual kills about 30 larvae of elder ages or about 40 adult aphids per day. During life span an individual of the bug is able to kill 3500 eggs or 2500 larvae of the whitefly. In the conditions of glass-covered ground the preys of the bug Macrolophus caliginosus are greenhouse whiteflies, different species of aphids, thrips, spider mites. The predator is applied on many vegetable (the tomato, the cucumber, the eggplant, the sweet pepper) and ornamental-flower crops (the rose, the chrysanthemum and etc.). The rate of predator invasion is 0.25–1 individual per 1 m2 for preventive application and 4–6 individuals per 1 m2 for the average and the high density of pest colonization. Invasions are realized in the morning or in the evening on isolated territory.



  • the long-term effect and the stable population of the entomophage;
  • resistance to low temperature;
  • the important component of complex IPM-programs against whiteflies.
