Plant, pest and predator interplay: tomato trichomes effects on Tetranychus urticae (Koch) and the predatory mite Typhlodromus (Anthoseius) recki Wainstein.

Trichomes are well-known efficient plant defense mechanisms to limit arthropod herbivory, especially in Solanaceae. The present study aims to evaluate the impact of trichome types on the development, survival and dispersal of Tetranychus urticae, and the phytoseiid predatory mite Typhlodromus (Anthoseius) recki. Six Solanum lycopersicum cultivars and two wild Solanum species, S.

Host adaptation and specialization in Tetranychidae mites.

Composite generalist herbivores are comprised of host-adapted populations that retain the ability to shift hosts. The degree and overlap of mechanisms used by host-adapted generalist and specialist herbivores to overcome the same host plant defenses are largely unknown. Tetranychidae mites are exceptionally suited to address the relationship between host adaptation and specialization in herbivores as this group harbors closely related species with remarkably different host ranges-an extreme generalist the two-spotted spider mite (Tetranychus urticae Koch [Tu]) and the Solanaceous specialist Tetranychus evansi (Te).

Molecular identification and phylogenetic analysis of spider mites (Prostigmata: Tetranychidae) of Turkey.

The family Tetranychidae includes many agriculturally important species known as spider mites. Their morphological identification is quite difficult due to the tiny size of their taxonomic characters and the requirement for high-level expertise. This may lead to pest misidentification and thus failure in pest management.

Improving safety of preparation and administration of medicines and enteral nutrition in a neonatal care unit: Global risk analysis.

Objective: To date, few adapted pharmaceutical forms are available for infants leading to multiple steps of preparation and medicines dilution before administration. The main purpose of this study was to assess the risks on the steps of preparation and administration of medicines in a neonatal care unit and to propose corrective actions to ensure the medicines safety.

Methods: A global risk analysis was performed, conducted by a multidisciplinary working group of 9 experts, that is 9 meetings.
