It has been used trichlorfon since the seventies, although it has the advantages of high efficiency, low toxicity and low price, but long-term use of a single variety of pesticides to produce pest resistance, aircraft spraying concentration From 80 times to 60 times.Thus there is an urgent need to choose new pesticides instead of or in exchange for the use of trichlorfon to overcome its resistance.In 1980 we selected three pyrethroid new pesticides on the Arborvitae moth Indoor efficacy screening test, the spring of 1981 combined with the aircraft worm, with deltamethrin (also known as the enemy killed) spray
