Abstract
The susceptibility of two field-collected bulb mites,Rhizoglyphus robini andR. setosus to some organophosphorus, carbamates, pyrethroids and other compounds with acaricidal activity was evaluated. In general,R. setosus was more tolerant to these compounds thanR. robini. Among the 58 commercially formulated compounds tested,R. robini was susceptible to chlorpyrifos 22.5% EC, EPN 45% EC, ethion 46.5% EC, fenitrothion 50% EC, methamidophos 50% S, methidathion 40% EC, mevinphos 25.3% EC, omethoate 25% EC, parathion 47% EC, phosmet 50% WP, profenofos 43% EC, prothiophos 50% EC, benfuracarb 20% EC, carbofuran 40.64% F, carbosulfan 48.34% EC, formetanate 50% SP, methiocarb 50% WP, azocyclotin 25% WP and cyhexatin 50% WP. Demeton-S-methyl 25% EC, methidathion 40% EC, phosmet 50% WP, profenofos 43% EC, prothiophos 50% EC, azocyclotin 25% WP and cyhexatin 50% WP gave good toxicity toR. setosus. Both species were tolerant to avermectin 1.8% EC and some newly developed synthetic pyrethroids, which were proved to have acaricidal activity. In addition, two bioassay methods were also evaluated for these two mites.
