| The susceptibility of Ectinohoplia rufipes, insect pest of landscaping trees in golf courses to registered insecticides in golf courses was investigated. In addition, effect of host plants, Ainus firma, Prunus serrulata var. spontanae, and Osmantus asiaticus on susceptibility of E. rufipes were tested in laboratory with efficacy of some insecticides in laboratory and fields. The insecticides used in experiments were cabaryl 40%+phosalone 20% WP, chlorpyrifos-methyl 25% EC, chlorpyrifos 20% + diflubenzuron 7% n, deltamethrin 1% EC, ethopenprox 8% +diazinon 25% WP, and fenitrothion 50% EC. Mortalities of E.rufipes were 100% except chlorpyrifos-methyl. when A. firma leaves dipped in recommended concentration of given insecticides were supplied as food to adult of E. rufipes. LC$_{50}$s of insecticides were different depending on host plants, that is, those of deltamethrin were 0.21 ppm in ¥Ï. asiaticus, 0.45 ppm in P. serrulata var. spontanae, and 0.77 ppm in A. firma. LC$_{50}$s of fenitrothion were 24.1 ppm, 64.0 ppm, and 11.0 ppm and those of chlorpyrifos-methyl were 97.2 ppm, 40.6 ppm, and 29.6 ppm, respectively. LC$_{50}$ was the lowest in ¥Ï. asiaticus and that of chlorpyrifos-methyl and fenitrothion was the lowest in A. firma. Deltamethrin was the most effective against adult of E. rufipes in field like in laboratory and persisted in two weeks.weeks. |
