Scientists Discover New Blossom Midge Species Contarinia ecardiflores Threatening Jasmine Crops in India

In a significant development for floriculture, scientists at the ICAR-Directorate of Floricultural Research (ICAR-DFR), Pune, have discovered a new species of blossom midge that is damaging jasmine crops in India. The species, named Contarinia ecardiflores, honors ICAR-DFR for its contributions to floricultural research, said Dr. D.M. Firake, the lead scientist of the study. 

Blossom midges of the genus Contarinia are known globally as serious pests of both ornamental and food crops. The newly identified C. ecardiflores causes considerable economic losses in jasmine cultivation, particularly by attacking flower buds. Although it is morphologically similar to Contarinia maculipennis, a previously reported jasmine pest, genetic studies have confirmed that it is a distinct species.

The research team used an integrated taxonomy approach, combining detailed morphological analysis with molecular techniques. Key features such as the structure of female flagellomeres, cerci, and the male aedeagus were studied.

In addition, sequencing of a partial mitochondrial cytochrome oxidase subunit I (COI) gene provided precise identification and a rapid method to distinguish this species from closely related pests.

C. ecardiflores completes its life cycle in 16 to 21 days, making it a persistent threat to jasmine production. Experts say that understanding its biology is essential for developing targeted and eco-friendly pest management strategies. Such interventions can help farmers safeguard their crops, reduce economic losses, and promote sustainable floriculture practices.
