Evaluation of native plant flower characteristics for conservation biological control of Prays oleae
Abstract Several studies have shown that manipulating flowering weeds within an agroecosystem can have an important role in pest control by natural enemies, by providing them nectar and pollen, whichExpand
Evaluation of the effects, on canopy arthropods, of two agricultural management systems to control pests in olive groves from north-east of Portugal.
This study aims to investigate the effect of management regime on canopy arthropod community of the olive tree (Olea europaea L.). Field studies were performed in two successive years, 2002 and 2003,Expand
Entomopathogenic fungi in Portuguese vineyards soils: suggesting a ‘Galleria-Tenebrio-bait method’ as bait-insects Galleria and Tenebrio significantly underestimate the respective recoveries of
Abstract Entomopathogenic fungi (EPF) are the natural enemies of insect-pests. However, EPF recoveries can be influenced by the soil habitat-type(s) incorporated and/or the bait-insect(s) used.Expand
Towards sustainable control of Lepidopterous pests in olive cultivation
Current olive growing practices range from the traditional Mediterranean olive grove to intensively managed olive plantations. Insecticides against major olive pests, like the olive moth (PraysExpand
Efficacy of spinosad bait sprays to control Bactrocera oleae and impact on non-target arthropods
A field study was conducted during 2005 and 2006 in Terra Quente, northeastern Portugal, to evaluate the efficacy of the spinosad-based insecticide Spintor Cebo® (Dow Agrosciences Ibérica, S.A.)Expand
Egg parasitoids of the genus Trichogramma (Hymenoptera, Trichogrammatidae) in olive groves of the Mediterranean region
A survey of egg parasitoids of the genus Trichogramma (Hymenoptera, Trichogrammatidae) was carried out in olive groves in Portugal, Greece, Egypt, and Tunisia during the years 2002–2004. ParasitoidsExpand
Natural mortality of immature stages of Bactrocera oleae (Diptera: Tephritidae) in traditional olive groves from north-eastern Portugal
Abstract From 2006 to 2008, we studied the natural mortality of olive fly, Bactrocera oleae (Rossi), eggs and larvae as collected in fruit on the tree, in two to five ‘traditional’ olive groves ofExpand
Influence of fruit traits on oviposition preference of the olive fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), on three Portuguese olive varieties (Cobrançosa, Madural and Verdeal
Abstract The olive fly, Bactrocera oleae (Rossi), is the major pest of olives in Mediterranean countries. Previous studies have stated that different olive tree varieties are not infested at the sameExpand
The use of the cumulative degree-days to predict olive fly, Bactrocera oleae (Rossi), activity in traditional olive groves from the northeast of Portugal
Terra Quente, situated in the province of Trás-os-Montes (northeast of Portugal), is one of the most important olive growing areas of Portugal. In this region, which is extremely hot and dry duringExpand
