Cardamom gall midge

Systematic position: Hallomyia cardamomi belongs to the order Diptera and the family Cecidomyiidae (gall midges). These insects are known for their highly specific relationship with host plants and their tendency to induce gall formation or inhabit internal fruit tissues.

Crops and economic impact: The species is an exclusive pest of cardamom (Elettaria cardamomum). It causes significant economic losses in regions where cardamom is grown commercially, as it directly attacks the marketable part of the plant—the capsules.

Biology and life cycle: The life cycle is closely tied to the flowering and fruiting period of the cardamom plant. The adult female lays eggs on the young flower buds or developing capsules. Upon hatching, the larvae bore into the capsule to feed on the developing seeds.

Damage symptoms: Infested capsules fail to mature properly, resulting in stunted, misshapen fruit. Inside, the seeds are often completely destroyed and replaced by the larvae and their debris, rendering the spice commercially useless and causing yield reduction.

• Conducting field inspections to detect early signs of gall formation.
• Removing and destroying infested capsules to reduce the larval population.
• Utilizing systemic insecticides during the peak flowering stage if infestation levels are high.
• Maintaining healthy soil fertility to improve plant resilience against pest pressure.
