Carrot weevils pose a serious risk to processing carrots in New Jersey. Perimeter traps involving carrots as bait have been useful in determining where around a carrot field infestations might occur but have not helped in determining infield activity. In 2004 pitfall traps and grooved blocks of wood were used to monitor activity. Adults were collected from both kinds of traps but did not predict the extent or severity of infestation of some fields. Eleven fields in 2005 are being evaluated using both types of traps with one field being mapped and gridded using GPS technology to determine the pattern of infestation.
