Morphomolecular characterization of invasive fruit borer infesting apple

Area of Science:

• Agricultural Entomology
• Pest Management
• Molecular Phylogenetics

Background:

• Apple cultivation is vital to India's economy, particularly in northern regions.
• Increased pest infestations, including invasive fruit borers, cause significant economic losses.
• An invasive fruit borer has severely damaged apple crops in India's Himalayan region.

Purpose of the Study:

• To identify the invasive fruit borer affecting apple crops in North India.
• To understand the pest's life cycle and genetic relatedness to existing populations.
• To provide data for effective management strategies against this apple pest.

Main Methods:

• Morpho-molecular characterization of the invasive pest.
• Collection of adult moths using delta sticky traps and rearing of larvae/pupae.
• Phylogenetic analysis of pest DNA sequences.

Main Results:

• The invasive borer was identified as codling moth (Cydia pomonella L.), a quarantine pest previously limited to Ladakh.
• Phylogenetic analysis indicated the pest is closely related to the Ladakh population.
• Codling moth completes three to four generations annually in Kashmir, with variations based on weather.

Conclusions:

• The spread of codling moth in North India poses a significant threat to apple production.
• Understanding the pest's life cycle and genetic makeup is essential for developing targeted control measures.
• Integrated pest management strategies are needed to mitigate economic losses in the apple industry.
