Common Pests Affecting Jackfruit
Shoot and Fruit Borer
- Egg to Adult: Females lay eggs and develop rapidly during flowering and fruiting periods. Larvae, identified by reddish-brown color with black spots, cause significant damage by burrowing into tender shoots and fruits.
- Damage: Contributes to 30─40% damage from flower bud to fruit ripening.
- Lifecycle: Eggs overwinter in twigs, hatching in early May. Nymphs secrete a protective spittle that helps them feed on tender one-year-old growth, leading to mold and twig damage.
- Damage: Feeding on twigs and subsequent mold development due to secretions.
- Lifecycle: Eggs laid on the host, producing mobile crawlers (first instar nymphs) that settle on plants, suck sap, and create colonies.
- Damage: Presence of white-powdered adults, honeydew excretion, flower drop, and sooty mold, affecting inflorescence and growth.
- Life Cycle: Egg to grub to full-grown grubs that bore into tender flower buds, causing premature dropping and infesting leaves.
- Damage: Hinders growth and causes flower drop.
Bark Eating Caterpillar
- Life Cycle: Females lay clusters of eggs on tree bark; resulting caterpillars damage tree bark and hinder sap flow.
- Damage: Nibbling on bark, creating silk webs, and affecting tree growth and fruiting.
- Lifecycle: Different nymphal stages (instars) suck sap from leaves, buds, and pods. Aphid attacks cause leaf curling, stunting, and the development of sooty molds.
- Lifecycle: Eggs hatch, leading to larval development in leaf folds; the pupation process includes silk cocoon formation.
- Damage: Larval feeding and presence of webbing on plant parts.
- Lifecycle: Eggs laid on trees, hatching into larvae that tunnel through the sapwood, causing large tunnels and disrupting sap flow.
- Damage: Hinders nutrient and water transport, wilting, and terminal shoot drying.
Castor Capsule Borer
- Lifecycle: Larvae bore into shoots and capsules, affecting tree health and producing characteristic webbing and excreta.
