Fidicina pullata

Fidicina pullata is a species of cicada belonging to the family Cicadidae within the order Hemiptera. This insect is recognized as a serious pest in tropical and subtropical regions, where its large populations can cause severe damage to agricultural plantations and native vegetation.

The primary host plants for Fidicina pullata include coffee trees, cacao, and citrus varieties. Both the adult stage and the underground nymphs feed on plant sap by piercing the xylem and phloem tissues, which drains the plant's resources and stunts its development.

The biology of Fidicina pullata is defined by a lengthy developmental cycle. Nymphs live underground for several years, feeding on roots, which makes them difficult to target. Adults eventually emerge, mate, and lay eggs into the stems of host plants, which facilitates the spread of the population across plantations.

Damage caused by this pest includes wilting of shoots, leaf chlorosis, and reduced harvest yields. The physical puncturing of plant tissues also creates entry points for secondary bacterial and fungal pathogens, which can exacerbate the decline of trees already weakened by sap loss.

Effective management and control measures include:

• Systematic monitoring of adult emergence during the peak season.
• Pruning and destroying branches containing egg clusters to prevent further hatching.
• Application of entomopathogenic fungi to target nymphs dwelling in the soil.
• Improving plant health through proper fertilization to help them withstand pest attacks.
• Targeted use of systemic insecticides during severe outbreaks to limit impact on non-target species.
