Biochemical responses, feeding and survival in the solitary bee Osmia bicornis following exposure to an insecticide and a fungicide alone and in combination.

In agricultural ecosystems, bees are exposed to combinations of pesticides that may have been applied at different times. For example, bees visiting a flowering crop may be chronically exposed to low concentrations of systemic insecticides applied before bloom and then to a pulse of fungicide, considered safe for bees, applied during bloom. In this study, we simulate this scenario under laboratory conditions with females of the solitary bee, Osmia bicornis L.

Use of Sugar Dispensers to Disrupt Ant Attendance and Improve Biological Control of Mealybugs in Vineyard.

(Signoret) and (Kuwana) (Hemiptera: Pseudococcidae) are economically important pests occurring in vineyards, causing severe economic losses for growers and compromising bunch production. The partial effectiveness of insecticides used in controlling mealybug infestations as well as their high impact on the environment and on human health have led to the research of alternative and sustainable control methods, including biological control. Several natural enemies are reported to be effective against mealybugs, but their activity may be hindered by tending ants.

Business innovation modes and their impact on innovation outputs: Regional variations and the nature of innovation across EU regions.

This work contributes to the literature on innovation systems and, in particular, delivers a thorough analysis on business innovation modes across a range of regional contexts. This analysis refers to the strand of literature on STI (Science and Technology-based Innovation) and DUI innovation modes (Innovation based on learning-by-Doing, learning-by-Using, learning-by-Interacting) that have been intensely debated over the past few years. It is a relevant area of research because it discusses the most effective innovation mode adopted by firms and their regions in the context of increasing global competition.

Adverse events following cannabis for medical use in Tuscany: An analysis of the Italian Phytovigilance database.

Aims: Despite a significant increase in using cannabis for medical purposes, current evidence on its safety in real-world clinical practice is still poorly characterised. By a case-by-case analysis of spontaneous reports of suspected adverse events (AEs) collected in Tuscany within the Italian Phytovigilance database, the aim of the present study was to describe AEs occurred in patients exposed to medical cannabis.

Methods: We evaluated all reports of cannabis-related suspected AEs collected within the Phytovigilance database up to December 2018.

The role of spp. and silica gel in plant defence mechanisms and insect response in vineyard.

Several elicitors, stimulating induced resistance mechanisms, have potential in preventing or mitigating pathogen infections. Some of these compounds, triggering the production of jasmonic acid (JA), a precursor of herbivore-induced plant volatiles, could also play a central role in indirect resistance to pest species, by improving beneficial arthropod performance, and necrotrophic pathogens. In the current work, Trichoderma gamsii/T.
