title: [The effects of six kinds of insecticides on gamasid mites].
abstract: The present paper reports on the results of six kinds including 14 chemical or biological insecticides on the gamasid mites. (1) Using organophosphorus compounds such as quinothion, supracide, bromochlophus, sumithion at a dose of 0.2g per m2, at a dose of 1 g per m2 abate, and malathion at a dose of 49 per m2, they were all sufficient to produce 100% mortality on the mites Eulaelaps stabularis; trichlorphon at a dose of 4g per m2 produced 96.4% kill of the mites. (2) Organochloride insecticide BHC containing 93% gamma HCH was not effective on the same mites. (3) at a dose of 0.1 g per m2 of pyrethroid; decis, all the Eulaelaps stabularis were knocked down immediately, but 87% of the mites recovered in 24 hours. (4) The acaricides and cycloprate, the molt-inhibiting hormone Su-urea No. 1 and No. 2, and Bacillus thuringiensis var, Isralensis had not effect on the mites Eulaelaps stabularis and/or Haemolae laps glasgowi, It is suggested that organophosphorus compounds should the insecticide of choice against the gamasid mites.
