NEW MATERIAL:A compound shown by formula I [R<1> is H or alkyl; A is ethylene or trimethylene which may be replaced with alkyl, respectively; X is O, S, NR<2> (R<2> is H, alkyl, alkenyl, etc.) or CHR<3> (R<3> is H or alkyl); Z is at least two hetero atoms (N, O or S)-containing 5--6-membered heterocyclic group, 3- or 4-pyridyl]. EXAMPLE:1-(2-Chloro-5-pyridylmethyl)-2-cyanoimidazolidine. USE:An insecticide having strongly insecticidal activity and showing excellently controlling effects on insect pests (especially stabbing, absorbing insect pests) having resistance to organic phosphorus insecticides and carbamate insecticides. PREPARATION:For example, a compound shown by formula II is reacted with a compound shown by formula III [M<1> is halogen, -OSO2-M<2> (M<2> is alkyl or aryl) to give a compound shown by formula I. |
