Key Points

The aim is to investigate the relationship between Cosmopolites sordidus and Fusarium oxysporum f. sp. cubense Tropical Race 4 outbreaks in banana crops.
Field studies assessing the population dynamics of C. sordidus and subsequent Foc TR4 outbreaks.
Statistical analysis correlating weevil abundance to Foc TR4 incidence.
C. sordidus populations consistently preceded Foc TR4 outbreaks by 1–2 months.
Weevil abundance accounted for 87% of the variability in Foc TR4 incidence.

Implication

Demonstrates the role of Cosmopolites sordidus in Fusarium oxysporum outbreaks in banana crops, indicating its importance in disease management.

Abstract

• C. sordidus populations precede Foc TR4 outbreaks by 1–2 months • Weevil abundance explains 87% of Foc TR4 incidence variability • Strong field evidence supports C. sordidus as a Foc TR4 potential vector
