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.

Spittle Bugs

  • 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.

Mealy Bug

  • 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.

Bud Weevil

  • 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.

Aphids

  • Lifecycle: Different nymphal stages (instars) suck sap from leaves, buds, and pods. Aphid attacks cause leaf curling, stunting, and the development of sooty molds.

Leaf Webber

  • 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.

Stem Borer

  • 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.
  • Damage: Boring into capsules, silk webbing, and hindering tree health.

Natural Enemies and Impact

Several parasitoids and predators naturally control the population of these pests. Bears, drawn to ripe jackfruit, contribute to ecological balance but also impact jackfruit trees during the summer months. Effective pest management and early detection are crucial to preserve jackfruit trees and fruit yield.
