Archive of Weekly ECB, CEW and BAW Distribution Maps

Corn Earworm and European Corn Borer maps have been produced weekly from May through October and disseminated to Rutgers Cooperative Extension faculty, staff, and growers via the weekly Plant and Pest Advisory newsletter via fax, mail and over the internet since 1999. In 2005, beet armyworm (BAW) was added for the southern counties from mid-Summer through the end of September.  Dissemination of timely pest population information to growers is critical to the success of the IPM programs as control decisions in IPM programs are often predicated on susceptible crop stage and pest population. 

The archived weekly pest maps are listed below.  To view past pest distributions, click on the link to the desired year.
