N-ALKYLSULFONYL-KONDENSIERTE HETEROCYCLISCHE VERBINDUNG ODER SALZ DAVON, PESTIZID MIT BESAGTER VERBINDUNG UND VERFAHREN ZUR VERWENDUNG DES BESAGTEN PESTIZIDS
In crop production in the fields of agriculture, horticulture and the like, the damage caused by insect pests etc. is still immense, and insect pests resistant to existing insecticides have emerged. Under such circumstances, the development of novel agricultural and horticultural insecticides is desired. The present invention provides a condensed heterocyclic compound represented by the general formula (1): {wherein R 1 represents a (C 1 -C 6 ) alkyl group, R 2 represents a halo (C 1 -C 6 ) alkyl group, G 1 , G 2 , G 3 , G 4 , G 5 , G 6 , G 7 and G 8 each represent CH or N, and m represents an integer of 0 to 2} or a salt thereof; an agricultural and horticultural insecticide comprising the compound or the salt as an active ingredient; and a method for using the insecticide.
