The experiment was conducted at the TAMU Agricultural Research and Extension Center at Beaumont, TX, in 1998 and was designed as an RCB with three treatments and four replications. Plot size was six rows x 50 ft long (30 inches between rows). Treatments are described in the tables. Plots were planted with ‘Haskell’ (Maturity Group VII) on 9 Jun. Seeding rate was eight viable seeds per ft of row. Soybeans emerged 16 Jun. On 7 Oct, when stink bug populations were increasing, selected plots were sprayed with the treatment insecticides. Insecticides were applied with a two-person, 20-ft spray rig (11 nozzles) pressurized with CO2. Nozzle tip size was 800067 and nozzles were equipped with 50 mesh screens. Final spray volume was 29 gpa. Five days before treatment applications, plots were sampled for arthropods with a 15-inch-diameter sweep net. Ten consecutive sweeps were taken in each plot. Arthropods from each sample were transferred to a plastic bag, which was frozen. At a later date, the contents of the bags were thawed, identified, and counted. One, 3, 9, 16, and 23 d after treatment applications, plots were sampled as described above. On each sample date, stage of development of soybeans was recorded. Plots were not harvested because of summer drought conditions that drastically reduced soybean yields. Arthropod counts were transformed using, O x + 0.5 and all data analyzed by ANOVA and means separated by DMRT (P = 0.05).
