Summer 1999: Aphid trapping data.

Results reported in this issue of Aphid Alert are total captures of winged aphids and species identifications for the following locations and sampling interval end-dates.  Additional sampling locations will be reported in the next issue of this newsletter. 

Also, potato leafhoppers are abundant in 1999.   Potato leafhoppers do not transmit potato pathogens, but feeding by this insect can severely damage potatoes.   Choose insecticide chemistries and rates with caution to avoid flaring aphids.

We intend to establish a list of e-mail addresses to facilitate communication with those of you interested in receiving updates about this research or any resulting advisories sooner than this information can be delivered by mail or even before it is posted on the WWW.  If you wish your name added to receive such messages please send us an e-mail at radcl001@umn.edu.   In the message, write "Aphid Alert subscribe."

ERRORS: If you find errors, typographic or factual, we would appreciate having them called to our attention so they can be corrected.  Phone: Robert Suranyi (218) 773-3346 or Ted Radcliffe (612) 624-773 or send an e-mail to radcl001@umn.edu.
