Satellite repetitive sequences that accumulate in the heterochromatin consist a large fraction of a genome and due to their properties are suggested to be implicated in centromere function. Current knowledge of heterochromatic regions of Bactrocera oleae genome, the major pest of the olive tree, is practically nonexistent. In our effort to explore the repetitive DNA portion of B. oleae genome, ...

A survey in olive orchards Istria (Croatia) was carried out from 2016 to 2018 investigate pathogens potentially associated with decline and dieback. In nine orchards, canker-like symptoms were recorded on trunks branches. Six fungal species isolated cankers: Geosmithia sp., Diaporthe Diatrype stigma, Diplodia seriata, Neofusicoccum parvum, Pseudophaeomoniella oleae. Pathogenicity tests conducte...

The olive fruit fly Bactrocera oleae targets the fruits of olive trees in the Mediterranean and has been causing increasing economic harm to Californian growers. Past efforts to combat Bactrocera oleae by limiting the spread of its population have included traps, bait sprays, barrier films, and the release of natural predators, but these methods do little against large populations and many frui...

A new species, Agistemus aimogastaensis, is described with the aid of optical and Scanning Electron Microscopy. This mite is an important predator of two eriophyid mites (Aceria oleae and Oxycenus maxwelli) in olive orchards (Olea europaea, variety Arauco) in La Rioja Province. The problems related to eriophyids in olive orchards in Argentina are highlighted and photos of the damage on leaves a...

Several photosensitizing agents, which are activated by illumination with sunlight or artificial light sources, have been shown to be accumulated in significant amounts by a variety of insects when they are administered in association with suitable baits. The subsequent exposure of such insects to UV/visible light leads to a significant drop in survival. Of the photosensitizers tested so far, x...
