• Xyleborus affinis

  sugarcane shot-hole borer

  Xyleborus affinis is a highly widespread ambrosia beetle native to the American tropics, now found in tropical and subtropical regions worldwide. It cultivates symbiotic fungi in galleries bored into decaying wood, feeding exclusively on these fungal gardens. The species exhibits facultative eusociality with delayed dispersal of adult offspring, who assist with nest maintenance and brood care. Females are the dispersing sex and are strongly attracted to ethanol and specific host plant volatiles. Despite frequent association with declining trees, it primarily colonizes wood already in early decay rather than causing primary mortality.
