Insect pests are insects that cause harm to crops, livestock, or human health. They can damage plants by feeding on leaves, stems, or roots, leading to reduced yields in agriculture. Common examples include aphids, caterpillars, and locusts, which can quickly multiply and create significant problems for farmers. In addition to agricultural damage, some insect pests can transmit diseases to humans and animals. For instance, mosquitoes are known carriers of diseases like malaria and dengue fever. Effective pest management strategies are essential to control these insects and protect both food supplies and public health.
