  • Abstract
  • La capture des chenilles nous a permis de constater les périodes de pullulation des adultes d’H. armigera au cours de la campagne. Il est apparu qu’entre le mois de septembre et celui d’octobre il y a une grande population d’adulte de H. armigera. Mais malheureusement, ce pic de capture de papillons ne coïncide pas toujours avec le pic de la population larvaire. La corrélation entre population larvaire et population d’adulte n’est pas encore clairement établie. Cependant, l’étude de la dynamiqu...

  • The dynamic of larval and adult populations and resistance management have been mainly examined. The results obtained show that resistance is unstable in farm and in laboratory. Resistance levels increase during insecticide selection pressure and decrease when treatments were stopped. There is not relation between larval population peak and adult one. Studing of pheromon trap can be used as agricultural alert device for insecticide treatment. The capture of caterpillars enables us to notice the ...
