Response of coccinellid community to the dimethoate application in olive groves...
Santos, SAP; Pereira, JA; Raimundo, A; Torres, LM; Nogueira, AJAIn this work we assessed the effects of the application of dimethoate on the coccinellid community. The field work was carried out on a weekly basis, in two different olive groves, from April to November of 2002 and 2003 and captured coccinellids were identified to species level. Principal response curves (PRC) method was used to analyse the effect of the dimethoate application on the abundance of coccinellid s...
Voracity of coccinellid species on different phenological stages of the olive p...
Santos, SAP; Pereira, JA; Torres, LM; Nogueira, AJNCoccinellidae are well known predators in agroecosystems. In olive groves they may exert control against scales, such as the black scale, Saissetia oleae (Olivier, 1791). Laboratory studies on the consumption of three phenological stages (eggs, first and second instar nymphs) of S. oleae by four coccinellid species (Chilocorus bipustulatus, Scymnus (Pullus) subvillosus, Scymnus (Mimopullus) mediterraneus and Sc...
