Abstract

Tagosodes orizicolus (Muir), better known as "Sogata" is consider an insect-pest of   economical importance in rice crop. The damages caused by this insect, can be direct   or mechanical and indirect, trough the transrnission of the virus (Virus de la Hoja   Blanca"). Several treatrnents with repeltent properties were evaluated in this article.   Three dosages of Biocrack® (0.5, 1.0 and 1.5 11 Ha) and Garlic® at 2.0 1/ Ha, were   compared with a cornmercial product as relative control (Actara® 100 g La. / Ha),   with the objective of provide elements which allow to establish a management   strategy for this insect-pest. The fleid trial was carried out in rice piot (Var. IDIAP L-7) in   the region of Chepo, Panama. 'flie experimental design was random block, with four   (4) repetitions per treatnient and the sample method used was sweeping net. 'flie   sampling frequency was 1, 3, 5, 7, 10, 12 and 15 D.A.A. (Days After Aplications).   llie rnost efficient treatrnent for the control of nymphs, was Biocrack® at 1.5 11 Ha,   statistically similar to Actara® until 12 D.A.A. The Biocrack® treatrnents between 0.5   and 1.5 11 Ha showed sorne degree of repellency in T. orizicolus adults although   showing to be efficient only at 1 D.A.A., due to migratory behavior in adults. The   methodology employed, didn't allow evaluating the effect of the treatments in the   benefit insects, suggesting trials in controlled conditions.
