CONTROLE DE LARVAS DE Diloboderus abderus COM INSETICIDAS EM TRIGO

Abstract: A larva de Diloboderus abderus Sturm (Coleoptera: Melolonthidae) é uma praga importante da cultura do trigo (Triticum aestivum L.) em plantio direto na região Sul do Brasil. Este estudo teve como objetivo avaliar diferentes inseticidas aplicados nas sementes (fipronil e tiametoxam) e via pulverização do solo (clorpirifós e lambdacialotrina) para o controle dessa praga. A eficiência dos inseticidas foi determinada através do número de larvas vivas no solo aos 30, 60 e 90 dias após a emergência das plantas (DAE)… Show more

“…In order to establish control measures, the economic damage level was studied and defined (Silva & Costa 2002 management techniques on behavior and density of larvae were carried out (Oliveira et al 2000). Tests to evaluate the efficiency in the use of chemical products in control of larvae were also done (Silva & Boss 2002).…”

“…In this bioassay, it is difficult to accurately know the amount of the insecticide absorbed by the insect, but the lethal effects caused by these insecticides on S. aloeus showed continuity of that trend with the application of the LC 90 concentration. The lethal effects of the insecticides and their effectiveness have also been studied in other pests under field conditions with fipronil being a potent control agent of Diloboderus abderus Sturm larvae, lambda-cyhalothrin and thiacloprid being a potent in controlling P. japonica larvae and adults, and thiamethoxam being a potent against Heteronychus arator Fabricius (Silva & Boss 2002;Drinkwater 2003;Baumler & Potter 2007).…”

“…The larvae of these species live in the soil, and are commonly called "white grubs" (MORÓN, 2004). Among these species, Diloboderus abderus Sturm, 1826, is the main damage-causing agent of the winter cereal crops and pastures, and is geographically distributed in the South of Brazil, Uruguay, and Argentina (GASSEN, 2001;SALVADORI & OLIVEIRA, 2001;SILVA & BOSS, 2002;SILVA & SALVADORI, 2004).…”
