Macrolophus bug

Important note: Macrolophus caliginosus is a predatory bug widely recognized in professional agriculture as a beneficial biological control agent, not a harmful pest. It is specifically used to manage populations of whiteflies and other greenhouse pests, though it may exhibit minor phytophagy if prey density is too low.

Taxonomically, this insect belongs to the order Hemiptera and the family Miridae. It is a slender, green-colored bug characterized by high mobility, which allows it to actively patrol plant foliage and effectively locate prey such as whitefly eggs and nymphs.

The primary crops for the release of this predator are tomatoes, peppers, and eggplants grown in protected structures. By preying on pests like Trialeurodes vaporariorum, the bug significantly reduces the need for synthetic pesticides, promoting a more sustainable and organic farming approach.

The life cycle of the bug consists of an egg stage, five nymphal stages, and the adult stage. The duration of development is highly dependent on ambient temperature, with optimal results observed at temperatures ranging from +20°C to +25°C. Both nymphs and adults are active predators from the moment of emergence.

• Highly efficient at controlling greenhouse whitefly.
• Also preys on spider mites, aphids, and leafminers.
• Can be used in integrated pest management (IPM) programs.
• Requires consistent monitoring to ensure population levels are sufficient.

To avoid potential plant damage caused by the bug's sap-feeding habits in the absence of enough pests, agronomists recommend providing supplemental food sources, such as brine shrimp eggs. This strategy ensures the predator population remains healthy and focused on hunting rather than consuming plant tissues.
