1. It refers to the use of it in the control of animal pests, including arthropods, especially insects, and in the preparation of compound 1: compound 1, wherein A1 and A2 are hydrogen, halogen, cyanogen, nitrogen, asphalt, cyclopentadiene or alcoxi respectively； G1 is n or c-a1, G2 is an excimer of formula group (a) to (d), and the arrow marks the connection with the adjacent ring in each case； R1 is hydrogen, halogen, cyanogen, hydrocarbon, alcox, aminobenzene, rental Mino, diaklamino, asphalt, tar or halotar with different formula periods (a) and (d),In the non orthogonal cycle, R1 is hydrogen, tar or halo tar； B is hydrogen, halogen, cyanogen, nitrogen, tar, cyclopentanediol, halo tar, aminobenzene, rental Mino, diallamino, hydrocarbon or alcoxi； G3 is optional alternative isopropene, alternative isopropene or arilo； G4 is un. From formula group (E) to (m) to various formula periods (a),(b) And (c) are also formula radical (n), in each case the arrow points to G3 link； X is oxygen or sulfur； n is 1 or 2； R2 is a radical substance of hydrogen, tar, halo tar, cyano methyl, alcox, haloxoxy, alquenilo, tar and ALCOXY, And in each case, asphalt and pitch, and in each case, carbonate, and in each case, cyclopropyl carbon, which are replaced by halogen, pitch, oxygen, halotars and cyanogens or a catalyst, For example, single metal ions or discrete metal ions or alternative ammonium ions are replaced by tar or arilalquilo； R3 and R7 are,Each ring can contain at least one heteroatom of sulfur and oxygen group (oxygen atom does not contain oxygen). Each ring can have a separate asphalt, calcium acylate and asphalt group. Each alternative ring can replace one ring. They must be directly adjacent) and nitrogen, as well as arilo, allomorph, arilalquilo and allomalodiene, which can be replaced in each case, and an alternative Amin group can be selected； R2 and R3 can also be formed together with the N-S (o) n group,A ring consisting of four to eight saturated or unsaturated o
