Residual Effect of Pesticides used in Integrated Apple Production on Chrysoperlaexterna (Hagen) (Neuroptera: Chrysopidae) Larvae

Temperate fruit crops are an important economic activity for growers in southern Brazil. However, several pest species are associated to apple (Malus domestica Borkh.) crops in Brazil. Pesticides are largely used to control them and one way to change this is to combine selective pesticides and preda...
