Major Insect Pests of Fruit Crops

Insect pests are the most notorious due to their direct feeding, reproductive damage, and potential to transmit diseases. The handbook emphasizes key pests such as fruit flies, codling moths, fruit borers, and scale insects.

1. Fruit Flies (Tephritidae and Drosophilidae)

Identification & Biology Fruit flies are small, often colorful, with distinct wing patterns. Their larvae develop inside ripening or fallen fruit, causing rot and drop. Damage Symptoms - Characteristic punctures or oviposition scars on fruit skin. - Soft, rotted flesh with larvae visible inside. - Premature fruit drop. Management Strategies - Monitoring: Use of bait traps with attractants such as methyl eugenol. - Cultural Control: Sanitation to remove fallen and infested fruits. - Chemical Control: Timed applications of larvicides or adulticides. - Biological Control: Introduction of sterile male techniques or parasitoids.

2. Codling Moth (Cydia pomonella)

Identification & Biology A key pest of apples, pears, and walnuts. The adult moth has a grayish-brown appearance with distinctive markings. Larvae tunnel into fruit, leading to internal damage. Damage Symptoms - Holes in fruit with frass deposits. - Worms inside the fruit. - Reduced market value due to internal tunneling. Management Strategies - Monitoring: Pheromone traps for early detection. - Cultural Control: Bagging or bagging fruit. - Chemical Control: Use of insect growth regulators and insecticides during vulnerable stages. - Biological Control: Deployment of Trichogramma spp. or Bacillus thuringiensis.

3. Fruit Borer Pests

Various fruit borers, such as the apple borer (Synanthedon exitiosa) and mango stem borer (Earias spp.), cause significant damage. Identification & Biology Larvae feed within fruit or stems, causing wilting and collapse. Damage Symptoms - Entry holes with frass. - Hollowed-out fruit or stem sections. - Premature fruit drop. Control Measures - Regular inspection and removal of infested parts. - Application of pheromone traps. - Use of targeted insecticides.

4. Scale Insects

Types & Impact - Soft scales (e.g., San Jose scale) and armored scales damage fruit surfaces and weaken trees. - Sucking sap reduces vigor and may transmit viral diseases. Management - Horticultural oils during dormant periods. - Biological control with natural predators like lady beetles and parasitic wasps. - Chemical control with systemic insecticides when necessary. ---
