Blossom Midge Felt (Diptera: Cecidomyiidae) Infestation in Floriculture: Impact on Tuberose, Jasmine and Orchids

The blossom midge, Contarinia maculipennis Felt (Diptera: Cecidomyiidae), is an emerging threat to high-value floricultural crops like jasmine, orchids, and tuberose across India. Its wide adaptability to diverse environmental conditions and ability to overcome climatic barriers have contributed to its emergence as a major threat in commercial floriculture. The larval stage develops hidden within flower buds, making detection and management particularly challenging. Moist soil conditions support successful pupation, while nocturnally active adults oviposit on the upper surfaces of young flower buds, which provide ideal nutrition and moisture for larval development. Understanding the pest?s biology, behavior, and damage potential is essential for identifying vulnerable points in its life cycle. Accurate identification through integrative taxonomic approaches and timely intervention during the early bud stage are critical for effective control. Integrated management strategies involving soil raking to disturb pupae, incorporation of granular insecticides, mulching, installation of yellow sticky traps, application of botanicals, and judicious use of chemical insecticides on both soil and foliage while avoiding irrigation during pesticide application are recommended. Coordinated, zone-wise implementation of these practices by farmers can significantly reduce midge populations and mitigate crop losses.
