Volume 6, No. 27 September 22, 1997
by Art Agnello & Dave Kain
Entomology, Geneva
With this issue, Scaffolds ceases publication for the season; we anticipate starting up again next March. In February, we'll be sending out response cards to all current subscribers to set up next year's mailing list. Our thanks to all of you who have sent comments, suggestions, and articles our way, a practice we hope you'll continue. As a wrap-up, we thought it would be a good idea to provide a summary of the year's pheromone trapping results and an Index of Volume 6, 1997 of Scaffolds Fruit Journal.
