Following cultivation-dependent and -independent techniques, we investigated the microbiota associated with Bactrocera oleae, one of the major agricultural pests in olive-producing countries. Bacterial 16S rRNA gene libraries and ultrastructural analyses revealed the presence of several bacterial taxa associated with this insect, among which Acetobacter tropicalis was predominant. The recent in...
Herbivorous activity induces plant indirect defenses, as the emission of herbivorous-induced plant volatiles (HIPVs), which could be used by parasitoids for host location. Psyttalia concolor is a larval pupal endoparasitoid, attacking a number of tephritid flies including B. oleae. In this research, we investigated the olfactory cues routing host location behavior of P. concolor towards B. olea...
Olive scale (Parlatoria oleae (Colvée)) is a common pest in Mediterranean olive orchards which primarily causes damage on olive fruits. The quality of virgin olive oil is strongly related to the health status of the olive fruits from which is extracted. In this paper the effects of olive scale (Parlatoria oleae (Colvée)) attack on the oil yield, chemical and sensorial quality, as well as on the...
Aim of the present article is to show the results obtained from the application of neuro-fuzzy methodology in the solution of agriculture problems like the Bactrocera Oleae (olive fly) infestation in the Liguria region olive grows. The research is focused to create an informatic decisional instrument to support experts in the applications of Integrated Pest Management strategies against the Bac...
In the present study, we reveal for the first time that the Bactrocera oleae chorion peroxidase (bPxd) participates essentially in B. oleae chorion formation and clearly represents the homologous member of Drosophila melanogaster chorion peroxidase (Pxd). Comparative sequence analysis disclosed that the bPxd cDNA semi-central region, which encodes for the putative catalytic domain of the enzyme...
The olive fly, Bactrocera oleae, is the most important pest affecting the olive industry, to which it is estimated to cause average annual losses in excess of one billion dollars. As with other insects with a wide distribution, it is generally accepted that the understanding of B. oleae population structure and dynamics is fundamental for the design and implementation of effective monitoring an...
Conservation biological control (CBC) is an environmentally sound potential alternative to the use of chemical insecticides. It involves modifications of the environment to promote natural enemy activity on pests. Despite many CBC studies increasing abundance of natural enemies, there are far fewer demonstrations of reduced pest density and very little work has been conducted in olive crops. In...
The olive fruit fly, Bactrocera oleae (Rossi), is an economically important and endemic pest in olive (Oleae europae) orchards in Turkey. The aim of this study was to determine olive fruit fly infestation in different olive cultivars in the laboratory. Olive fly infested fruits were collected in Çanakkale province to establish wild fly population. After having reproductive olive fly colonies, 1...
So far the limited knowledge about diet of omnivores and generalist predators in olive groves has not allowed clarification their role as natural enemies. Stable isotope (δN15 δC13) analysis is a useful tool for predicting trophic position high number species, variety basal resources flux energy food web. We have explored possible consumers two important pests grove: adults Prays oleae Bern (Le...
