Short-horned fruit spotting bug

Amblypelta brevicornis is a species of insect belonging to the order Hemiptera and the family Coreidae. Known as a significant agricultural pest, this insect is infamous for its ability to damage a wide variety of high-value tropical and subtropical crops, impacting production in several regions.

The host range of this bug is extensive, with major economic losses reported in cacao, mango, avocado, and various nut plantations. The bug primarily targets young shoots, developing flowers, and fruit, utilizing its piercing-sucking mouthparts to extract sap and introduce salivary toxins into the plant tissues.

The life cycle involves incomplete metamorphosis, progressing through egg, nymphal, and adult stages. Nymphs typically resemble smaller versions of adults but are wingless. The insects rely on the availability of succulent plant tissues for their growth, often synchronizing their peak activity with the flushing and fruiting stages of the host trees.

Damage caused by Amblypelta brevicornis is characterized by characteristic lesions, tissue necrosis, and distortion of young growth. The most severe impact is seen when feeding leads to premature fruit drop or terminal dieback, which can result in the loss of entire harvest clusters if left unmanaged.

• Monitor plantations for early signs of tissue necrosis.
• Implement regular pruning of infested shoots.
• Use biological control agents or predators if applicable.
• Apply targeted insecticides when pest population thresholds are reached.

Managing this pest requires an Integrated Pest Management (IPM) approach. This involves regular scouting for adults and nymphs, maintaining orchard hygiene to remove alternate host plants, and applying chemical control measures strategically during the most vulnerable development stages of the crop to minimize impact on beneficial insects.
