Ameles

The genus Ameles belongs to the order Mantodea and the family Mantidae. While these insects are essentially predators, they are often classified as unwanted guests in intensive agricultural settings. Their presence in high density can lead to a significant decline in populations of beneficial pollinators and parasitic wasps, which are crucial for natural crop protection against primary pests.

Various crops, including vineyards, cereal fields, and horticultural plants, serve as habitats for these insects. Ameles species utilize these plants for camouflage and hunting. While they are not primary plant eaters, the cumulative effect of their presence can lead to physical damage to stems and leaves, particularly during the egg-laying phase when females deposit oothecae on plant surfaces.

The lifecycle of Ameles follows incomplete metamorphosis, progressing through egg, nymph, and adult stages. The female lays eggs in specialized capsules called oothecae, which are resistant to harsh environmental conditions. The nymphs hatch and immediately begin hunting, passing through multiple molting stages throughout the growing season to reach maturity.

Damage caused by this insect is primarily indirect. The reduction of beneficial insect populations creates a biological vacuum that can be exploited by other pests, such as aphids or lepidopteran larvae. Additionally, high populations of Ameles can interfere with the daily operations of crop management, as their oothecae can contaminate harvested materials or plant structures.

Effective control measures focus on integrated pest management (IPM) strategies. Monitoring population densities is essential to determine if intervention is required. Cultural practices include:

• Removal of crop debris after harvest to destroy oothecae.
• Maintenance of field margins to support alternative prey.
• Avoidance of broad-spectrum insecticides that kill beneficial predators.
• Strategic pruning to remove egg-infested plant parts.
