The tarnished plant bug (Lygus lineolaris; TPB) is native to the eastern US but has spread throughout much of North America.In North Carolina, they are sporadic but sometimes serious fruit pests. If you find more than 0 but less than 3, (or, between 1 and 5 if you are using a high threshold) you must continue sampling.

Here are some photos long overdue of a ladybug ( Harmonia axyridis , or Multicolored Lady Asian Beetle) with an injured wing. From silver tip to petal fall, place at least three traps per block about 11/2 feet (45 cm) above the ground cover. Clouded plant bugs or cotton fleahoppers were a low percentage of the total plant bug population in these tests and were counted as equivalent to tarnished plant bugs when making threshold calculations. Control Controlling weeds in and around strawberry fields reduces in-field overwintering and removes sources of early-season flowers that attract adult tarnished plant bugs to fields. A&T State University, in all 100 counties and with the Eastern Band of Cherokee tarnished plant bug adults are present in the field and sweep net samples produce more than 2 tarnished plant bug adults per 10 sweeps as buds begin to form. Blanchard township, Driftless Prairies, Lafayette County, Wisconsin, USA. It has piercing-sucking mouthparts and has become a serious pest on small fruits and vegetables in North America. Depending on the temperature the nymphs will hatch in 7- 10 days. Feeding releases digestive enzymes that causes cell death, distorted growth, and seed damage all of which result in misshapen fruit. To save time, a sequential sampling plan may used to determine how many clusters should be sampled. Amazing!! Most locations were sampled and sprayed once per week, but twice-weekly samples were sometimes taken, and insecticides were applied as needed.
