Cercospora leaf spot of olives is a serious defoliating disease attributed to Pseudocercospora cladosporioides. Although the disease is well distributed throughout olive growing regions of the world, its epidemiology and population structure remains unknown. The aim of this study was to establish the genetic variability of Spanish isolates of P. cladosporioides using DNA sequence data from the ...

BACKGROUND Symbiotic bacteria affect insect physiology and ecology. They may also mediate insecticide resistance within their hosts and thereby impact pest and vector control practices. Here, we document a novel mechanism of insecticide resistance in which a gut symbiont of the tephritid pest fruit fly Bactrocera dorsalis enhances resistance to the organophosphate insecticide trichlorphon. RE...

from Lolium perenne, Olea europaea, Artemisia vulgaris, Parietaria judaica and Platanus acerifolia.(Figure 1). Oral challenge test with raw cardoon produced pruritus in mouth and lips swelling 30 min after the ingestion whereas oral challenge with cooked cardoon did not produce any kind of symptomatology. We report a case of cardoon allergy confirmed by positive results in in vivo and in vitro ...

Eco-friendly synthesis of nanoparticles, which is one of the most advanced evergreen branches of nanoscience for biomedical application. This synthesis is non toxic and very low cost are major features of production it further attractive prospective option for biomedical field and elsewhere. In this investigation, the anticancer potentiality of AuNPs, stabilized with Olea europaea L was studied...

INTRODUCTION The phenolic compounds present in olive leaves (Olea europaea L.) confer benefits to the human health. OBJECTIVES To review the scientific literature about the benefits of the polyphenols of olive leaves to human health. METHOD Literature review in the LILACS-BIREME, SciELO and MEDLINE databases for publications in English, Portuguese and Spanish with the descriptors "Olea euro...

The Chinese citrus fruit fly, Bactrocera minax, is an economically important pest of citrus. It exhibits pupal diapause from November to May to combat harsh environmental conditions. Such a long pupal diapause is a barrier for laboratory rearing and development of control strategies against this pest. In the present study, 20-hydroxyecdysone (20E) was used to break pupal diapause of B. minax by...

Bacteria of the genus Stenotrophomonas are ubiquitous in the environment and are increasingly associated with insects. Stenotrophomonas maltophilia SBo1 was cultured from the gut of Bactrocera oleae The draft genome sequence presented here will inform future investigations into the nature of the interaction between insects and their microbiota.

Soil treatments with Metarhizium brunneum EAMa 01/58-Su strain conducted in both Northern and Southern Spain reduced the olive fly (Bactrocera oleae) population density emerging from the soil during spring up to 70% in treated plots compared with controls. A model to determine the influence of rainfall on the conidial wash into different soil types was developed, with most of the conidia retain...

A method for use in high-throughput screening of bacteria for the production of long-chain hydrocarbons and ketones by monitoring fluorescent light emission in the presence of Nile red is described. Nile red has previously been used to screen for polyhydroxybutyrate (PHB) and fatty acid esters, but this is the first report of screening for recombinant bacteria making hydrocarbons or ketones. Th...
