Evaluation of the effects, on canopy arthropods, of two agricultural management systems to control pests in olive groves from north-east of Portugal.
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 (Prays…
Natural mortality of immature stages of Bactrocera oleae (Diptera: Tephritidae) in traditional olive groves from north-eastern Portugal
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 of Trás-os-Montes (north-eastern Portugal), per year is studied.
Efficacy of spinosad bait sprays to control Bactrocera oleae and impact on non-target arthropods
Spintor Cebo® seems to be a good alternative to control the olive fruit fly in Continental Mediterranean climates such as Terra Quente, but its use should be evaluated carefully, mainly in conditions that increase the arthropod biological control agents’ propensity for feeding on it.

The results suggested that all beneficial insects were able to reach nectar of the plant species from Apiaceae family, i.e. Prays oleae was not able to access nectar from five plant species, and the architecture of the flowers as well as the mouthpart structure and/or the head and thorax width of the pest and its enemies were analyzed.
Entomopathogenic fungi in Portuguese vineyards soils: suggesting a ‘Galleria-Tenebrio-bait method’ as bait-insects Galleria and Tenebrio significantly underestimate the respective recoveries of…
This is the first report on C.cicadae isolation from Mediterranean soils as an EPF worldwide; and significant recoveries of M.robertsii using TM over GM are reported.
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…
The effect of sooty mold on fluorescence and gas exchange properties of olive tree
It is concluded that sooty mold infection could affect light reaching leaves and the normal physiological metabolism of the plant (as photosynthesis would be affected), with consequences for production.
Egg parasitoids of the genus Trichogramma (Hymenoptera, Trichogrammatidae) in olive groves of the Mediterranean region
Insect-associated fungi from naturally mycosed vine mealybug Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae)
New insights are provided into the development of mycoinsecticides and conservation biocontrol strategies for P. ficus pest management and the first isolations of EPF from vine mealybug worldwide are reported.
