경남 지방의 장미원으로부터 채집된 점박이응애(Tetranychus urticae)의 지역별 살비제 감수성 = Acaricide Susceptibities of Field-Collected Population of Two-spotted Sider Mite, Tetranychus urticae (Acari : Tetranychidae) from Rose Orchards at Kyung-Nam Province Area

다국어 초록 (Multilingual Abstract)

Susceptibities of Two-spotted Spider Mite (Tetranychus urticae Koch) collected at 5 locations were assessed to 10 acaricides. The response to acaricides were almost similar in female adults and eggs.
There were considerable difference in susceptibility depending on the acaricide treated and the region from which the population was collected. The population showing resistance ratio of more than 20 with respect to certain acaricide was regarded as a resistant population to the acaricide.
The resistant population in terms of female adult were as follows : Kimhe population to azocyclotin, cyhexatin, and fenbutatin-oxide ; Changweon population to dicofol and fenbutatin-oxide ; Tongyeong population to dicofol ; Chinju population to cyhextin, dicoful and fenbutatin-oxide ; Haman population to cyhextin and azocyclotin.
The resistant populations in terms of egg were as follows : Kimhe population to bifenthrin, hexythiazox and tetradifon ; Changweong population to bifenthrin and amitraz : Tongyeong population to dicofol and tetradifon ; Chinju population to amitraz, clofentezine, and bifenthrin ; Hamang population to hexythiazox, dicofol, and bifenthrin. However, the female adults and eggs of all field population were susceptible to abamectin only. This tendency was also reported previously in the susceptible strain from laboratory.
