 per sweep of alfalfa, causing no observable damage in Centre County; numerous 

 adults attracted to lights of houses. (Gesell) . 



NORTHERN CORN ROOTWORM (Diabrotica longicornis ) - PENNSYLVANIA - Adults averaged 

 4 per sweep of alfalfa, and less than 5 percent of females gravid in Centre

COTTON 



BOLLWORMS (Hellothis spp.) - NEW MEXICO - H. zea generally light on cotton in 

 Dona Ana County. (N.M. Coop. Rpt . ) . TEXAS - H. zea light in Pecos Valley. Less 

 than 2 percent larval infestation reported from most counties. Light, with less 

 than 8 eggs per 100 plant terminals and less than 2 larvae per 100 plants in 

 El Paso Valley. Light increase reported from Midland County, larvae 5-10 per 100 

 terminals and damaged squares 5-7 percent in isolated fields. Light with 2 

 percent larvae infestation in most fields in Glasscock County. (Neeb) . ARKANSAS - 

 Still found in many fields. Moth flights decreased; still potential for economic 

 damage in suitable fields. Cotton remained green enough to attract moths away 

 from soybeans. (Boyer et al.). TENNESSEE - H. zea damage occurring in late cotton 

 by late instar larvae. (Locke). Late instar larvae damaged large bolls in

 in Midland County. Heavy in several north-central counties from fields still 

 squaring. Some harvesting underway in this area. (Neeb, Turney) . ARKANSAS - 

 Controls effective with infestation levels reduced in many fields. Emergence of 

 weevils will continue to bring about considerable activity. Newly emerging adults 

 will be developing diapause soon. (Boyer et al.). TENNESSEE - Damage heavy to 

 small bolls in western areas. (Locke). Damaged small bolls in late cotton in 

 southern middle areas. New generation of adults emerging. (Gordon). ALABAMA - 

 Still heavy statewide. Weevils migrating to younger and more acceptable fields.
