Description:

The tarnished plant bug, Lygus lineolaris (Heteroptera: Miridae), is a highly polyphagous pest that feeds on a broad range of economically important crops in North America. Flying L. lineolaris adults can move from crop to crop rapidly and easily. Little is known about the movement of L. lineolaris in or near vineyards. From May to October 2002 and 2003, 39 white sticky traps were positioned inside and at the periphery of a vineyard to study the movements of tarnished plant bug adults. Tarnished plant bug captures were most numerous from the end of July to mid August, with captures of ca. 3000 individuals in one week. During the vegetative season, most individuals were captured flying in and around the vineyard at a height of between 40 and 60 cm. The frequency with which the weeds were mown affected the numbers of adults captured. At the periphery of the vineyard, tarnished plant bug was more abundant near perennial vegetation, which tends to be stable (an apple orchard, a spruce wood), than in the vineyard where agronomic activities changed the availability of food. The tarnished plant bug adults did not hibernate in the vineyard. It is suggested that appropriate weed management will reduce the abundance of tarnished plant bugs in vineyards as it would deprive them of a number of suitable hosts for feeding and oviposition.
