Prevention of Spider Mite Dispersal with Creased Vinyl

Abstract

The efficiency of folded vinyl in preventing dispersal of spider mites was investigated. Mites could not climb over vinyl surfaces with 30 or 45 degree lapels and wandered under them. These “fences” greatly reduced the number of mite immigrants into a spinach field with a vinyl rain cover, and were also very effective in preventing emigration of mites from a box into which post-harvest strawberry plants colonized by many mites were being abandoned. © 1990, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
