Publisher's Synopsis
Excerpt from Proceedings of the State Horticultural Association of Pennsylvania for 1932
In all, 530 individuals were removed from the eight trees, of which 388, or percent, were in the bands. The favorite cocooning places outside the bands seemed to be the narrow crotches that could not be scraped clean, and pruning scars and cankers among the upper branches, together w1th bark scales on the trunk and main branches that had not been removed, or had loosened up after the scraping, which was done in June. All these shelters were more abundant at Floradale than at State College. Apparently the thoroughness with which other favor able hibernating places can be removed from the trees will determine to a large extent the proportion of the total population trapped by the bands. With a highly effective band, control of the moth population of an orchard will vary from 70 to 95 percent, depending upon the smoothness of the trees.
What is the place of treated bands in the codling moth control program - The decision to use chemically-treated bands in addition to spraying and packing house sanitation rests, of course, with the individual grower, and should be based on a thorough knowledge of the codling moth situation in his own plantings. The experience of the Experiment Station with the codling moth and with the practice of banding, may justify the following suggestions.
