The 10 ft tall container grown trees were held in a nursery holding area on the Michigan State University Campus in East Lansing, Michigan for the duration of this test. To alleviate drift problems, branches were dipped in the appropriate pesticide solutions on 30 May. Treatments were replicated 6 times with a replication consisting of an individual branch. Several trees had up to 4 branches with different treatments. Sleeve cages were put on the branches and ten 2nd instar larvae were placed within each cage on 4 Jun. Larvae were counted on 7 Jun and 11 Jun by rolling back the cages and counting live larvae.
