The role of insecticidal application and host plant resistance in managing Spodoptera exigua has been well documented, but the effect of different host plants, on which the pest cycles its population in the field, has seldom been investigated. Therefore, we have studied the vulnerability of S. exigua against commonly used insecticides (cypermethrin, chlorpyrifos, lufenuron, and emamectin benzoa...

O objetivo desta pesquisa foi determinar a linha básica de resistência Spodoptera frugiperda (Smith) aos inseticidas fipronil, lufenuron, permetrina e metomil, por meio bioensaios suscetibilidade pressão seleção em populações laboratório. trabalho realizado nos laboratórios Entomologia da Faculdade Ciências Agrícolas Universidade Técnica Babahoyo, localizada no km 7,5 estrada Babahoyo-Montalvo....

The article presents an assessment of the biological effectiveness biorational insectoacaricides based on abamectin and emamectin benzoate – metabolites soil actinomycetes, to protect grapes from pests. We studied new drugs: Mekar, ME (18 g/l abamectin) Mabet, EC against Schizotetranychus pruni ; Yunona, (50 benzoate), Emakleim, VRG benzoate) Proclame Fit, WDG (400 g/kg lufenuron + 50 emamectin...
