The following test example will demonstrate that the compounds are useful as the active ingredients of pesticide compositions. The com- pounds (X) are designated by their compound numbers shown in Table 1.

Test Example 1 Pesticidal Test against Nilaparvata lugens Each formulation of the compound 11,12,16,27,30,31,32,33,34,37, 40,41,42,47,49,52,56,58,59,60,63,64,65,67,69,71,75,79,87,88, 89, 90,98,100,102,105,106,108,109,110,114,115,116,117,118 and 119 obtained according to Formulation Example 5 was diluted with water so that the active ingredient concentration came to 500 ppm to prepare a test liquid for each compound.

Fifty grams of molding Bonsoru 2 (available from Sumitomo Chemi- cal Co., Ltd.) was put into a polyethylene cup, and 10 to 15 seeds of rice were planted in the polyethylene cup. Then rice plants were grown until the second foliage leaves developed and then cut into the same height of 5 cm.

The test liquid, which had been prepared as described above, was sprayed at the rate of 20 ml/cup onto these rice plants. After the test liquid sprayed onto the rice plants were dried, the polyethylene cup with the rice plants was

placed in a large polyethylene cup and 30 first-instar larvae of Nilaparvata lugens (brown planthopper) were set free in the large polyethylene cup, which was then kept covered and left in a greenhouse at 25°C. On the 6th day after the release of larvae of Nilaparvata lugens, the number of parasitic Nilaparvata lugens on the rice plants was examined.

As a result, in the treatment with each of the compounds described above, the number of parasitic pests on the 6th day after the treatment was not greater than 3.

Test Example 2 Pesticidal Test against Nilaparvata lugens Each formulation of the compound 11,12,16,41,45,47,49,52,54,58, 68,69,71,75,87,90,105,106,108,109 and 110 obtained according to Formulation Example 5 was diluted with water so that the active ingredient concentration came to 45.5 ppm to prepare a test liquid for each compound.

Fifty grams of molding Bonsoru 2 (available from Sumitomo Chemi- cal Co., Ltd.) was put into a polyethylene cup having five holes of 5 mm, and 10 to 15 seeds of rice were planted in the polyethylene cup. Then rice plants were grown until the second foliage leaves developed and the polyethylene cup with the rice plants was placed in a large polyethylene cup containing 55 ml of the test liquid, which had been prepared as described above. The rice plants were left in a greenhouse at 25°C for 6 days and then cut into the same height of 5 cm. Thirty first-instar larvae of Nilaparvata lugens (brown planthoppers) were set free in the large polyethylene cup, which was then kept covered and left in a greenhouse at 25°C. On the 6th day after the release of larvae of Nilaparvata lugens, the number of parasitic Nilaparvata lugens on the rice plants was examined.

As a result, in the treatment with each of the compounds described above, the number of parasitic pests on the 6th day after the treatment was not greater than 3.

Test Example 3 Pesticidal Test against Nilaparvata lugens Each formulation of the compound 1,2,3,4,5,6,8,9,10,11,12,13, 14,15,16,17,18,19,21,22,23,24,25,26,27,29,44,48,49,51,62,66, 73, 74,76 and 77 obtained according to Formulation Example 1 was diluted with water so that the active ingredient concentration came to 500 ppm to prepare a test liquid for each compound.

A bundle of 3 to 4 of cotyledons (height of 3 to 5 cm) of rice was immersed in the test liquid, which had been prepared as described above, for 1 minute. After the test liquid treated the rice plants was dried, a filter paper moistened with 1 ml of water was place on a bottom of polyethylene cup and then the bundle of cotyledons of rice was placed on it. Thirty first- instar larvae of Nilaparvata lugens (brown planthoppers) were set free in the polyethylene cup, which was then kept covered and left in a greenhouse at 25°C. On the 6th day after the release of larvae of Nilaparvata lugens, the number of parasitic Nilaparvata lugens on the rice plants was examined.

As a result, in the treatment with each of the compounds described above, the number of parasitic pests on the 6th day after the treatment was not greater than 3.

Test Example 4 Pesticidal Test against Diabrotica undecimpun- etc ta Each formulation of the compound 1,2,3,4,5,9,10,11,12,16,19,21, 22,23,24,26,66,74 and 76 obtained according to Formulation Example 1 was diluted with water so that the active ingredient concentration came to 50 ppm to prepare a test liquid for each compound.

On the bottom of a polyethylene cup of 5 cm in diameter was placed a filter paper, to which the test liquid had been prepared as described above, was added dropwise in an amount of 1 ml. One germinated seed of corn and 30 to 50 eggs of Diabrotica undecimpunctata (southern corn rootworm) was

placed on the filter paper in the polyethylene cup, which was then kept covered and left in a room at 25°C. On the 6th day after, the number of surviving larvae of Diabrotica undecimpunctata was examined.

As a result, in the treatment with each of the compounds described above, the number of surviving pests on the 6th day after was 0.

Test Example 5 Pesticidal Test against Musca domestica Each formulation of the compound 1,3,4,10,11,15,17,22,24,30,31, 32,33,34,35,36,37,39,40,41,42,43,45,46,47,52,55,56,57,58,59, 60, 64,65,66,67,68,69,71,74,75,79,82,84,89,90,92,101,102,105,107 ,108, 109,110,111,114,115 and 120 obtained according to Formulation Example 5 was diluted with water so that the active ingredient concentration came to 500 ppm to prepare a test liquid for each compound.

On the bottom of a polyethylene cup of 5.5 cm in diameter was placed a filter paper on the same size, to which the test liquid had been prepared as described above, was added dropwise in an amount of 0.7 ml, and 30 mg of sucrose as a bait was placed on it. Ten female adults of Musca domestica (house fly) were set free in the polyethylene cup, which was then kept covered. After 24 hours, their survival was examined to determine the mortality.

As a result, in the treatment with each of the compounds described above, it was exhibited the mortality of 100%.

Test Example 6 Pesticidal Test against German cockroach Each formulation of the compound 1,2,3,4,5,9,10,11,12,15,16,17, 23,30,31,32,33,36,39,40,41,42,43,46,47,52,55,56,57,58,59,60, 64, 68,69,74,79,84,89,102,109,110,114,119,120 and 121 obtained in Formulation Example 5 was diluted with water so that the active ingredient concentration came to 500 ppm to prepare a test liquid for each compound.

On the bottom of a polyethylene cup of 5.5 cm in diameter was placed

a filter paper on the same size, to which the test liquid had been prepared as described above, was added dropwise in an amount of 0.7 ml, and 30 mg of sucrose as a bait was placed on it. Two male adults of German cockroach (Blattalla germanic) were set free in the polyethylene cup, which was then kept covered. After 6 days, their survival was examined to determine the mortality.

As a result, in the treatment with each of the compounds described above, it was exhibited the mortality of 100%.

Test Example 7 Pesticidal Test against Cullex pipiens pallens Each formulation of the compound 1,2,3,4,5,6,7,9,10,11,12,13, 15,16,17,19,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36, 37, 38,39,40,41,42,43,44,45,46,47,48,52,54,55,56,57,58,59,60,61, 63, 64,65,66,67,68,69,70,71,74,75,76,78,79,80,81,82,83,84,89,91, 92, 97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112 ,113, 115,116,118 and 121 obtained according to Formulation Example 5 was diluted with water so that the active ingredient concentration came to 500 ppm to prepare a test liquid for each compound.

In 100 ml of ion-exchanged water, the test liquid had been prepared as described above, was added dropwise in an amount of 0.7 ml (the concentration of active ingredient was 3.5 ppm). Twenty final-instar larvae of Cullex pipiens pallens (common mosquito) were set free in the solution.

After 1 days, their survival was examined to determine the mortality.

As a result, in the treatment with each of the compounds described above, it was exhibited the mortality of 100%.
