Abstract

Disclosed is a compound represented by formula (1):

wherein A 1 represents N(O) p or CH; A 2 represents N(O) q ; R 1 represents a trifluoromethyl group, a halogen atom or a hydrogen atom; R 2 represents a C1-C3 perfluoroalkyl group, p represents 0 or 1; q represents 0 or 1; n represents 0, 1 or 2; and m represents 0, 1 or 2, having an excellent controlling effect on pests.

First claim

The invention claimed is:

1. A fused heterocyclic compound represented by formula (1):

wherein
A 1 represents N(O) p or CH,
A 2 represents N(O) q ,
R 1 represents a trifluoromethyl group, a halogen atom or a hydrogen atom,
R 2 represents a C1-C3 perfluoroalkyl group,
p represents 0 or 1,
q represents 0 or 1,
n represents 0, 1 or 2,
m represents 0, 1 or 2,
with the proviso that when A 1 is NO and/or A 2 is NO, n represents 2 and m represents 2.

2. The fused heterocyclic compound according to claim 1 , wherein A 1 is CH.

3. The fused heterocyclic compound according to claim 1 , wherein A 1 is N.

4. The fused heterocyclic compound according to claim 1 , wherein R 1 is a hydrogen atom.

5. The fused heterocyclic compound according to claim 1 , wherein R 1 is a trifluoromethyl group.

6. The fused heterocyclic compound according to claim 1 , wherein R 2 is a trifluoromethyl group.

7. The fused heterocyclic compound according to claim 1 , wherein p is 0 and q is 0.

8. A pest control agent comprising a fused heterocyclic compound according to claim 1 and an inert carrier.

9. The pest control agent according to claim 8 , wherein the inert carrier is water, and the fused heterocyclic compound is dispersed in the water containing a surfactant.

10. A method for controlling an arthropod pest, which comprises applying an effective amount of the fused heterocyclic compound according to claim 1 .

11. The method according to claim 10 , which comprises applying an effective amount, of the fused heterocyclic compound to stem and leaf of a plant or a soil where a plant is grown.

12. The pest control agent according to claim 8 , wherein the inert carrier is an eating carrier.

13. The pest control agent according to claim 8 , wherein the inert carrier is a solvent and a propellant gas.

14. The method according to claim 10 , which comprises spraying a pest control agent comprising the fused heterocyclic compound and an inert carrier comprising a solvent and a propellant gas to an arthropod pest and/or a habitat of an arthropod pest.

15. The pest control agent according to claim 8 , wherein the inert carrier is a gas-forming agent.

16. The method according to claim 10 , which comprises applying the fused heterocyclic compound to the body surface of an animal parasitized by an arthropod pest.
