초록
Flupyrazofos [O,O-diethyl-O-(1-phenyl-3-trifluoromethyl-5-pyrazoyl)thiophosphoric acid ester]는 trifluoromethyl기가 존재하는 피라졸계통의 유기인계 살충제이다. 이 화합물은 배추좀나방에 대해서 탁월한 살충활성을 나타내었으며, 또한 작은각시들명나방과 멸강나방에 대해서도 우수한 살충활성을 나타내었다. 배추좀나방의 알, 번데기, 성충에 대해서는 살충효과가 떨어지지만, 유충은 발육 단계에 관계없이 강한 살충효과를 나타내었으며, 살충효과의 발현속도는 매우 빨랐다(
Flupyrazofos (O,O-diethyl-O-(1-phenyl-3-trifluoromethyl-5-pyrazoyl)thiophosphoric acid ester) is a new organo-phosphorous insecticide. Flupyrazofos has exhibited excellent activity against diamondback moth (Plutella xylostella, DBM), and it is highly activity against rice armyworm(Pseudaleta separata) and cotton caterpillar(Palpita indicae). Flupyrazofos has then revealed outstanding both rapidity and residual action for DBM, although no systemic actions were observed and no cross-resistances were found to the resistance strains (Op-R, Py-R, IGR-R). Also, susceptibilities of five local strains to flupyrazofos were similar to those of the susceptible strain. These results indicate that flupyrazofos has considerable potential for controlling diamondback moth, rice armyworm and cotton caterpillar in field.
