The black vine weevil (BVW), Otiorhynchus sulcatus (Fabricius), is a particularly troublesome pest for growers of ornamental and other nursery crops. In addition to field and landscape plantings, it commonly infests containerized perennials in greenhouse and polyhouse production settings, feeding on over 100 different kinds of trees, shrubs, vines, and flowers.
Unfortunately, knowledge about the behavior and movement of this insect is very incomplete, thereby hampering the development of effective control measures.
In response to this problem, scientists with the USDA ARS Application Technology Research Unit have developed a Harmonic Radar Transponder to track black vine weevil movement.
Researchers and growers can use the behaviorial information gathered using this technology to develop improved or alternative management strategies and more effectively time and target control measures.
