Early in July 1959, a request was received at the Peninsular Branch Experiment Station in Door County, Wisconsin, from a cherry grower asking for a recommendation for chemical control of walkingsticks on cherry. This unusual request was further compounded by the fact that the problem was not one caused by feeding on the foliage, but one related to cherry pickers during harvest. The grower had extensive acreage in orchards and annually contracted for Jamaican labor to help harvest the fruit. The Jamaican workers were superstitious about the walkingsticks and were reluctant and sometimes even refused to work in infested orchards. Although close to harvest, the grower wanted to spray the orchards with a safe, effective, nonpersistent, insecticide, to reduce the walkingstick population and thus help quiet the fear of the pickers.
