Typification and current status of the Turkish taxa described by Hanna Czeczott

TAXON, EarlyView.
Abstract Hanna Czeczott's 1925 expeditions to northern Turkey resulted in the description of 22 new taxa. Our study revisits them using Czeczott's original publications and herbarium collections. Of the 22 taxa described, we located all or parts of the original material for 21, designate 13 lectotypes (including one second‐step) and confirm 7 holotypes,

Variation in physiological host range in three strains of two species of the entomopathogenic fungus Beauveria [PDF]

, 2018
Knowledge of the host range of a biocontrol agent (BCA) is fundamental. Host range determines the BCA's economic potential, as well as the possible risk for non-target organisms. Entomopathogenic fungal strains belonging to the genus Beauveria are widely

Effects of crop species on soil functions and soil multifunctionality are species‐specific

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil multifunctionality is essential for sustainable agriculture, as soils not only need to support crop growth but also maintain soil biodiversity and sustain other critical ecosystem functions.

Population suppression of Ceratitis capitata (Wiedemann) on table grapes using toxic baits

Anais da Academia Brasileira de Ciências
To provide alternatives to the use of spraying synthetic insecticides in C. capitata management, was evaluated the effect of “attract and kill” toxic baits on population suppression of C. capitata in three commercial areas producing table grapes.

Effect of the essential volatile oils isolated from Thymbra capitata (L.) Cav. on olive and sunflower oils

Grasas y Aceites, 2003
The chemical composition of the volatile constituents of the oils isolated from different parts of Thymbra capitata collected at different developmental stages were analysed by GC and GC/MS. The antioxidant ability of the oils isolated from T.

Microbial symbionts : a resource for the management of insect-related problems [PDF]

, 2011
Microorganisms establish with their animal hosts close interactions. They are involved in many aspects of the host life, physiology and evolution, including nutrition, reproduction, immune homeostasis, defence and speciation.

Exploring the impact of a chemical disinfectant and an antiviral drug for RNA virus management in the Mediterranean fruit fly mass‐rearing

Insect Science, EarlyView.
Abstract The Mediterranean fruit fly is an agricultural pest of a wide variety of fruit crops. An effective method to counteract them in the field is through the application of the sterile insect technique, which requires the mass‐production of sterile males.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...
