• Example 2 Rice Planthopper Foliar Test The stock solution (3000 ppm) prepared in Example 2 for each compound tested was diluted to 1000 ppm (test solution) . Using a spray atomizer, each test solution was sprayed onto a separate pot containing approximately 20 Mars variety rice seedlings. One day after spraying, the plants were covered with a tubular cage and twenty adult rice delphacides, Sogatodes orizicola, were transferred into each cage. Five days after transferring, counts were made of the surviving planthoppers in each pot and percent control was estimated.

• Two corn seedlings were soaked in a test solution for 1 hour and then transferred to the petri dish containing the same test solution. After 24 hours, each dish was loaded with 5 second instar larvae of the southern corn rootworm, Diabrotica undecimpunctata. After five days, the number of live larvae were determined and the percent control, corrected by Abbott's formula (see J. Economic Entomology, 18, 265-267 (1925)) , was calculated.
• Tobacco Budworm Test The undiluted stock solution (3000 ppm) (test solution) prepared in Example 2 for each compound was used for this test. 0.2 ml of each test solution was pipetted onto the surface of each of 5 diet cells, allowed to spread over the surfaces and air dried for two hours. Then a second instar larva of Heliothis virescens was introduced into each cell. After 14 days, the number of living larvae was determined for each test solution and percent control, corrected by Abbott's formula, was calculated. The results of the testing of tobacco budworms (TB) are given in Table 2 below.

• Rice Planthopper Systemic Test 200 ppm test solutions of the compounds were prepared by dissolving 0.01 gram of each compound to be tested in 5 ml of acetone and adding 45 ml of distilled water plus 2 drops of ethoxylated sorbitan monolaurate. Each of a series of pots held about 475 grams of moist soil and contained approximately 20 Mars variety rice seedlings, 8 days old from seed. A 25 ml aliquot of each test solution was injected into the root zone of a separate pot with a hypodermic needle and syringe. The resulting soil concentration of each compound tested was 10 ppmsc (parts per million soil concentration) .
