Granulate Ambrosia Beetle in Tree Fruit
A farm in Southern NJ is experiencing an infestation of the granulate ambrosia beetle, Xylosandrus crassiusculus (Mot.). GAB was identified by expert Dr. James Lashomb at Rutgers. Adults are hunch-backed in appearance and are cinnamon or brownish in color. Females are 2.1-2.9mm in length and males are 1.5mm. Offspring are small white and legless c-shaped larvae.
Females bore into trunks or limbs and excavate a system of tunnels in the wood. The beetles feed on living trees and carry a mutualistic fungus with them. When GAB females attack a tree, they introduce the fungus, which also is used as a food source. Eggs, larvae, and pupae are found together in galleries. There are related ambrosia beetles that attack apple and are present in other states and it is possible we have multiple species.

Fall Urea Sprays for Apple Scab Control
It’s time to consider sanitation practices that can help reduce over wintering scab inoculum. These practices should be considered an essential part of apple IPM programs.

Bug Damaging Cranberries Identified: Plagiognathus repetitus
This year we observed damage to cranberries likely caused by an unknown “mirid” bug (Hemiptera: Miridae). These insects are known as true bugs and have piercing-sucking mouthparts to suck juices out the plants. The species has now been identified by Dr. Thomas Henry, from USDA-ARS-Systematic Entomology Laboratory in Beltsville, MD, as Plagiognathus repetitus (Hemiptera: Miridae).

Red Blotch Virus Alert Meeting
South Jersey vineyard and winery managers are invited to an Alert Meeting at Auburn Road Vineyard and Winery, 117 Sharptown-Pilesgrove Road, Woodstown, NJ on Monday September 29th at 4:30 PM to 6:30 PM.
Do you have plants that look like this?
It may be a virus symptom.We often see red leaves in vineyards at this time of the season, which can result from many causes including viruses, mineral deficiencies, trunk injury, and crown gall. In a season like 2014, following a damaging winter, the most common causes include the aftereffects of cold injury to the woody parts of the vines and the subsequent crown gall infections.
There are several well-documented types of viruses known to have serious deleterious effects on the performance of grape vines with names like Grape Leaf Roll and Grape Fan Leaf. A newly identified virus, generally called Red Blotch, is present in New Jersey vineyards. Red Blotch biology and potential impact on vineyard performance is yet to be worked out.
