Trunk-Implanted Systemics for Control of Foliage Insects on Shade Trees in California1
In trials in northern California during 1965--66, implantation at 6-inch intervals around the tree-trunk cir-conference with either Bidrin® (3-hydroxy-N,N-dimethyl- cis-crotonamide dimethyl phosphate) or oxydemetonmethyl provided effective and long-term control of various aphids on ash, Fraxinus spp., and elm, Ulmus spp., trees. Reductions were only moderate on linden, Tilia cordata Miller, and erratic on birch, Betula spp., and maple, Acer spp. Aphid control on oak, Quercusspp., with Bidrin was poor. Bidrin and oxydemetonmethyl provided effective control of Neoborus spp. on ash and elm leaf beetle, Pyrrhalta luteola (Muller), on elm. Impiant treatment failed to control Empoasca satula Delong on birch, and Stomacoccus platani Ferris and Lithocolletis felinella Heinrich on western sycamore, Platanus racemosa Nuttall. In ash, elm, oak, and sweet gum, Liquidambar styraciflua L., uptake of .Bidrin was slower during the period of rapid shoot elongation in the spring than immediately before or after this period. In elm during September, uptake of .Bidrin was more rapid during the period 10 AM to 6 PM than at any other time of day or night.
