Toxicity of tebufenozide, an ecdysteroid agonist, to [i]Blattella germanica[/i] (Blattodea: Blattellidae)
2014
The toxicity of the non-steroidal ecdysteroid agonist tebufenozide was evaluated topically on adults of the cosmopolitan cockroach Blattella germanica (Blattodea: Blattellidae). The LD50 value was estimated at 402 mu g/g of insect (range, 95% fiducial limits: 293-552) at 15 days after treatment. The effects on reproduction were observed in adult females of cockroaches that survived exposure to a LD25 (146 mu g/g of insect) of tebufenozide. Dissection of treated females showed a clear reduction in both the number of oocytes per paired ovaries and the size of basal oocytes, as compared to controls. In addition, tebufenozide significantly reduced the mating success of pairs and altered the fer…
Black currant project: Multidisciplinary approach to agro-ecological measures
2022
The decline of wild pollinators leads to a drastic drop in the associated ecosystem service, resulting in significant lossesin agricultural yields. The production of blackcurrant “Noir de Bourgogne” could potentially be tripled, if populationsof wild pollinators were restored. Various agroecological measures beneficial to pollinators are discussed here, as wellas ongoing experimental tests. We discuss the practical possibilities of implementing these measures by blackcurrantgrowers as well as the technical locks that still exist. The return to an agroecological equlibrium for which pollinationbecomes again a free ecosystem service for agriculture, requires the integration of multiple agroec…

Biological responses to high-frequency sound in a freshwater crayfish, Cherax quadricarinatus
2023
Anthropogenic noise is recognised as an important environmental stressor that can have longterm negative consequences on species. In recent years, there has been increasing attention to the potential negative impact of noise pollution on species, with great concern for the importance of impacts on aquatic animal life. This study examined the effects of acoustic stress on the biochemical parameters of the freshwater crayfish Cherax quadricarinatus. The experiment was conducted in a tank equipped with an audio and video recording system using ten groups (five control and five test) of three adult crayfish (30 animals in total). The animals in the test group were exposed to acoustic signals [a…
Muscle Function Differences between Patients with Bulbar and Spinal Onset Amyotrophic Lateral Sclerosis. Does It Depend on Peripheral Glucose?
2021
Background: One of the pathogenic mechanisms of ALS disease is perturbed energy metabolism particularly glucose metabolism. Given the substantial difference in the severity and the prognosis of the disease, depending on whether it has a bulbar or spinal onset, the aim of the study was to determine metabolic differences between both types of ALS, as well as the possible relationship with muscle function. Materials and Methods: A descriptive, analytical, quantitative, and transversal study was carried out in hospitals and Primary Care centers in the region of Valencia, Spain. Fasting glucose and alkaline phosphatase (AP) levels in venous blood, muscle percentage, fat percentage, muscle streng…
