New soybean pest confirmed in Missouri for second time

MU Extension state crops entomologist Ivair Valmorbida confirmed the latest finding of the soybean tentiform leafminer in Macon County on Aug. 19. First detected in Missouri in 2025, this emerging pest feeds inside soybean leaves, creating distinctive "mines" that can reduce leaf area.
Farmers are encouraged to scout soybean fields, especially along field edges near wooded areas, and contact their local MU Extension agronomist if they suspect soybean tentiform leafminer activity. Researchers are continuing to study the insect's distribution and potential impact on soybean production.
