European grapevine moth, Lobesia botrana

The European grapevine moth occurs in Africa, Asia, North America, South America, and Europe. It most commonly attacks grapevine crops but has a wide variety of other host plants including, cheery, plumb and pomegranate. Larvae bore into grapes and secure the grapes with silk to avoid them dropping. In heavily infested areas 20 or 30 larvae may live on one cluster. Secondary infection of fruit causes fungal and acid rot. Larvae feed on leaves, shoots, and growing points on all host plants. The moth has one to four generations a year dependant on environmental conditions. Monitor adults using Mothcatcher or Delta traps with species-specific pheromone lures in order to time treatments and reduce crop damage.
