One important difference is that grape root borer (GRB) larvae feed inside grape roots, while wasp larvae do not. Pheromone traps can also be used to measure adult emergence, but since they attract moths from both the surrounding woods and vineyards, they are practically useless to tell us what is going on in any specific vineyard. During that time we found 3 vineyards that had populations of GRB that merited treatment, or were above the 5% infestation level. Magnolia reported to be attacked (USDA FS 1985), but this is questionable. Grape root borer pupal skin partially visible in soil. Injection of systemic insecticides is often a preferred method for controlling insect pests in landscapes because it eliminates potential spray drift thereby reducing applicator exposure and it minimizes impacts on non-target organisms. Once applied, the treatment will be absorbed by the trees root system and as it gets dispersed up and into the tree, it will kill any insect feeding on the protected foliage. Secondly most GRB adults emerged from the soil a little later than we first thought. Woodpecker damage is sometimes confused with that of wood-boring beetles; however, woodpecker damage will not produce frass. We recommend first using a contact insecticide such as Sylo Insecticide to the tree trunk, limbs, and bark to kill any active borers are inside the tree. One of the problems with Lorsban® 4E is that the soil around the base of the vines must be kept weed-free in order for it to be effective.

When the larvae mature, they exit the wood and pupate close to the soil surface where they emerge from early July through August. (It seems more likely that a related borer in magnolia, E. magnolialis Capps, was mistakenly identified as E.

Many root-borer-infested pecan orchards are also heavily infested with crown gall on the roots. Treatments: If the vineyard has an economic population, then the standard treatment would be using Lorsban at the start of adult emergence, which would be now in most years. During 2015 -’16 we monitored 2 plantings at each of 9 vineyards. Adult females lay eggs on the vine surface and on weeds near the crown. Lorsban Advanced: Use 4.5 pt/100 gal, with 2 qt applied to a 15 sq ft area around each vine; Lorsban 4E: Use the same amount as with the ‘Advanced’; Lorsban 75WG: Use 3 lb/100 gal, with 1.5 qt applied to 11 sq ft around each vine.

After overwintering as a larvae, they return to the … Collection of grape root borer moths in the traps not only alerts you to the potential problem, but can also be used to determine the initiation of insecticidal treatments. Counting pupal cases is labor intensive, but does tell us if the vineyard is or is not truly infested. A new pheromone system for the control of grape root borer has recently been introduced, but the pheromone mix is that of another moth species, not grape root borer.
