Eumastacidae
Systematic position: Eumastacidae, commonly known as monkey grasshoppers, belong to the order Orthoptera and the suborder Caelifera. They are distinct from typical locusts due to their unique body shape, often elongated limbs, and specific habitat preferences that are characteristic of certain tropical and subtropical ecological zones.

Eumastacidae
Affected crops: These pests pose a significant threat to a variety of agricultural and horticultural crops. Their diet includes citrus trees, coffee plantations, various cereal crops, and ornamental plants. By feeding on foliage, they cause significant physiological stress to the host plants during their active growth stages.
Biology and lifecycle: The lifecycle of Eumastacidae follows a pattern of incomplete metamorphosis. Females typically deposit eggs in the soil or protected crevices of plant matter. After hatching, nymphs undergo several molting stages, with their development rate highly dependent on ambient temperatures and humidity levels prevalent in their environment.
Damage and economic significance: Both nymphs and adult insects are voracious feeders. They consume leaves, often stripping plants entirely. This damage reduces the photosynthetic capacity of the plants, leading to stunted growth, reduced fruit production, and in severe cases, the complete death of young seedlings and economically valuable shrubs.
Control measures: Integrated pest management (IPM) is essential for controlling Eumastacidae. This includes regular field scouting to identify infestation hotspots, the application of targeted insecticides during early nymphal stages, and habitat modification, such as tillage, to disrupt their egg-laying sites and reduce overall population densities.
- Frequent monitoring of crop health.
- Application of contact or systemic insecticides.
- Tillage of agricultural lands to destroy eggs.
- Promotion of natural predatory insect populations.
