Green iguana

The green iguana (Iguana iguana) is a member of the Squamata order, family Iguanidae. While frequently kept as pets, green iguanas have become a severe agricultural pest in various parts of the world, specifically in subtropical regions where they have been introduced and lack natural predators to control their numbers.

These lizards are strict herbivores. They feed on a vast range of crops, including leafy vegetables, fruits, flowers, and foliage of young trees. In agricultural settings, they are known for devastating nurseries, small vegetable farms, and landscaped gardens, often consuming high-value cash crops in a very short amount of time.

The biology of Iguana iguana involves burrowing into the ground to lay eggs, which directly impacts crop health. These deep tunnels disrupt soil structure, damage root systems, and can cause erosion in cultivated fields. Their reproductive cycle is rapid in warm climates, allowing populations to overwhelm local ecosystems if left unmanaged.

The damage caused by green iguanas is characterized by defoliation and the consumption of tender shoots and buds. By stripping plants of their leaves, iguanas inhibit the growth of the crop and can lead to total yield loss. Furthermore, they cause damage to agricultural infrastructure, such as irrigation pipes and fencing, often through their movement and burrowing activities.

To protect agricultural interests, an integrated pest management strategy is required. Key strategies include:

• Installing specialized metal fencing to prevent entry into growing areas.
• Utilizing motion-activated sprinklers or noise-based deterrents to scare them away.
• Removing vegetation or debris that provides shelter for iguanas.
• Implementing habitat modification to make the agricultural site less attractive to these reptiles.
