Micromus angulatus

Micromus angulatus belongs to the order Neuroptera and the family Hemerobiidae. Contrary to being classified as a plant pest, this species is widely recognized by agronomists as a highly effective beneficial insect, specifically an entomophagous predator that helps control aphid populations in various crops.

The biology of this species is characterized by a complex life cycle including eggs, three larval stages, a pupal stage within a silken cocoon, and adult development. Both the larvae and adults are active hunters, utilizing sensory capabilities to locate and feed on soft-bodied prey such as aphids on foliage.

This insect does not cause damage to crops. It is strictly carnivorous, focusing its predation efforts on aphids, scale insects, and mites. Because it does not feed on plant tissues, it does not pose any threat to the yield or health of the cultivated plants.

In terms of economic value, Micromus angulatus acts as a natural control agent. By maintaining a stable population of these lacewings, farmers can significantly lower the need for chemical insecticides. They are essential components of integrated pest management (IPM) strategies in orchards, greenhouses, and field crops.

Strategies to support and preserve these beneficial predators focus on habitat maintenance and chemical safety. Key measures include:

• Avoiding the use of broad-spectrum insecticides that harm non-target insects.
• Implementing selective pest control measures that target only specific pests.
• Cultivating flowering plants around fields to provide nectar and pollen for adult lacewings, ensuring their long-term presence.
