Green lacewing

Taxonomic position: Chrysopa lateralis belongs to the order Neuroptera and the family Chrysopidae. In professional agronomy, species within the Chrysopa genus are widely recognized as beneficial predators rather than pests, as they are instrumental in controlling populations of aphids, mealybugs, and mites in various crops.

It is crucial for growers to correctly identify these insects before taking any management actions. Labeling this insect as a pest is often a misinterpretation of its role in the ecosystem, as its larvae serve as one of the most effective natural enemies against widespread sap-sucking pests in orchard and row crop environments.

Biology and lifecycle: The lifecycle consists of four stages: egg, larva, pupa, and adult. Eggs are typically laid on long stalks to prevent cannibalism among emerging larvae. The larvae, often called aphid lions, are highly mobile and voracious predators that can consume hundreds of prey items during their developmental period before pupating.

Damage and pest status: There is virtually no evidence of this species causing damage to healthy plant tissues. On the contrary, their presence is a positive indicator of integrated pest management success. They do not feed on leaves, stems, or fruits, making them harmless to crops in the context of direct feeding damage.

Management measures: No control measures are recommended as these insects are essential for organic and conventional pest suppression. To protect these predators, farmers should avoid the overuse of broad-spectrum insecticides that kill beneficials, which often leads to secondary pest outbreaks. Encouraging floral diversity in field margins helps maintain their population levels.
