• G. quadrisignatus is 5- 6 mm (1/4 inch) long, dark brown to black with two pale yellow spots on each wing cover
• Carpophilus spp. are usually elongate, flat, oval beetles that vary from 2- 4 mm (1/8 inch) in size
• Most species are pale to dark brown-black

Management Notes

• Establish roadways or dedicated spray rows in the field at suitable intervals to minimize damage caused by farm equipment.
• Avoid crushing of fruit at picking time.
• For processing crops, harvest as close as possible to time of delivery to the factory. 
• If loaded wagons are not delivered immediately, leave them exposed to air circulation.
