Beschreibung
Zusammenfassung:	The invention discloses an O,O-dialkyl-alpha-[3-bromo-1-(3-chloro-2-pyridyl)-1H-pyrazole-5-formyl]alkyl methylphosphonate derivative of which the general formula I is as shown in the description, wherein R represents a methyl group, an ethyl group, a propyl group or a butyl group; R represents halogen, hydrogen, a methyl group or a methoxy group. The invention further discloses preparation methods of like compounds of the O,O-dialkyl-alpha-[3-bromo-1-(3-chloro-2-pyridyl)-1H-pyrazole-5-formyl]alkyl methylphosphonate derivative. The like compounds have remarkable inhibiting effects on three insecticide targets such as armyworms, aphids and red spiders, and can serve as efficient ingredients of an insecticide.
