Tarnished plant bug
The tarnished plant bug (TPB) or ''Lygus lineolaris'' is a species of plant-feeding insects of the family Miridae. It has piercing-sucking mouthparts and has become a serious pest on small fruits and vegetables in North America. It feeds on over half of all commercially grown crop plants, but favors cotton, alfalfa, beans, stone fruits, and conifer seedlings. This bug can be found across North America, from northern Canada to southern Mexico. Adults grow up to 6.5 mm in length, and are brown with accents of yellow, orange or red, with a light-colored "V" on the back (dorsal).
==Control==
Insecticides: Growers routinely make 3-5 applications of insecticides each year to control this insect. Considering the narrow profit margin for today's farmers, the cost of such applications are significant.
Biological control: In the mid 1980s, parasitic wasps, ''Peristenus digoneutis'', were imported from France and their acculturalization in the north-eastern United States has resulted in reduction of crop losses to the TPB of up to 63% in alfalfa and 65% in apples.〔 The University of Vermont Entomology Laboratory studied various entomopathogenic fungi for pathogenicity against TPB. The fungus ''Beavaria bassiana'' is sometimes used to control TPB.
