Glyphodes pseudocaesalis

Glyphodes pseudocaesalis is a lepidopteran insect belonging to the family Crambidae. This moth is recognized as a significant agricultural pest primarily affecting trees of the genus Artocarpus, which includes important tropical crops such as jackfruit and breadfruit.

The host range of G. pseudocaesalis is relatively specific, focusing on Moraceae family members. The larvae are the destructive life stage, causing damage to foliage, young shoots, and developing fruits, which directly impacts the productivity and yield quality of these essential fruit-bearing trees.

The biology of the species follows a typical holometabolous life cycle: egg, larva, pupa, and adult. Eggs are laid on plant tissues, and larvae emerge to feed on leaf surfaces or tunnel into fruits. They often utilize webbing to fold leaves or bind fruit surfaces, providing a microhabitat that shields them from environmental stress and predators.

Damage caused by this pest is characterized by irregular holes in leaves, often leading to severe defoliation. Fruit damage is arguably more critical, as larval boring activities lead to secondary infections, internal decay, and premature fruit abscission, rendering the harvest unmarketable.

• Regular monitoring of orchard canopy for leaf webbing symptoms.
• Mechanical removal and disposal of infested fruit and foliage.
• Utilization of biological control agents, including parasitoids and entomopathogens.
• Application of selective insecticides during the peak periods of larval emergence.

Implementing an integrated pest management (IPM) program is essential for controlling G. pseudocaesalis. By combining orchard sanitation with biological and targeted chemical interventions, growers can significantly reduce population density and protect their fruit production from economic losses.
