Abstract
An insect monitoring network was established on commercial vegetable farms in southeast Michigan and northwest Ohio during the 2009 growing season. The following insect pests were monitored using pheromone traps: diamondback moth ( Plutella xylostella), squash vine borer (Melittia cucurbitae), corn earworm (Helicopverpa zea), European corn borer (Ostrinia nubilalis), western bean cutworm ( Striacosta albicosta), fall armyworm (Spodoptera frugiperda) and variegated cutworm (Peridroma saucia). These insects were monitored from late May until late September in sweet corn, cucurbit, cabbage, and tomato plantings. Some of these pests, such as the European corn borer, occurred in very small numbers and infestations of sweet corn and pepper fields were very rare. Other species, such as the corn earworm and diamondback moth, were very common throughout the region and trapping data were very important in providing growers indications of potential infestations of these pests. Overall, the monitoring network provided growers with timely insect population data which allowed them to make appropriate control decisions. This network will be expanded and developed additionaly during 2010 and subsequent years.
