Resumen

CORREA-MENDEZ, Azalia et al. Chemical control of the red palm mite Raoiella indica Hirst (Acari: Tenuipalpidae). Ecosistemas y recur. agropecuarios [online]. 2018, vol.5, n.14, pp.319-326. ISSN 2007-901X.  http://dx.doi.org/10.19136/era.a5nl4.1340.

The aim of this study was to compare the biological effectiveness of 19 commercial acaricides for the control of Raoiella indica Hirst populations in Tabasco, Mexico. The acaricides were sprayed on the foliage of hybrid coconut plants (Alto del Pacifico x Enano Malayo), previously infested with R. indica, at the recommended dosage and frequency of application. The number of mites that remained alive on the abaxial surface of the foliage at 2, 7, 14 and 21 d after application was recorded. The acaricides bifenthrin, acequinocyl, bifenazate, spiromesifen, amitraz, fenpyroximate, chlorfenapyr, sulfur, formetanate hydrochloride, milbemectin, propargite and fenazaquin were the most effective, reducing the populations of R. indica by more than 95% at 7 d after application. The sequenced use of these acaricides in the region is proposed, based on their modes of action, for a rational chemical control of the pest.
