Hemiptera are a diverse group of insects known as true bugs, many of which have profound effects on agriculture. Their specialized mouthparts enable them to suck sap from plants, leading to direct damage, transmission of plant pathogens, and reduced crop yields. Some Hemiptera species, such as aphids, whiteflies, and scale insects, are notorious pests that can cause extensive economic losses. However, not all Hemiptera are harmful; some predatory species help control other insect pests, providing natural pest management benefits.
  • Hemiptera use piercing-sucking mouthparts to extract plant sap, causing direct damage.
  • Some species transmit viruses, bacteria, or phytoplasmas, acting as vectors for plant diseases.
  • Common pest groups include aphids, whiteflies, scales, and mealybugs.
  • Predatory Hemiptera (e.g., assassin bugs) contribute to biological control in agroecosystems.
Hemiptera use piercing-sucking mouthparts to feed on plant sap.
Aphids are Hemiptera that are major agricultural pests.
Hemiptera affect crops by causing direct sap loss, transmitting diseases, and reducing photosynthesis.
Not all Hemiptera are harmful; some are beneficial as predators of pest insects.
