Implications of cyantraniliprole sublethal doses on the population dynamics and gene expression of Aphis gossypii Glover (Hemiptera: Aphididae).

Cyantraniliprole (CYA), widely recognized as a highly effective solution, is widely used in pest management. It has been broadly utilized to manage diverse pests, among which Aphis gossypii Glover (Hemiptera: Aphididae) is a prominent agricultural pest that leads to significant crop damage worldwide. Studies suggest that the sublethal effect of insecticides might contribute to the resurgence of A.

Metabolic characteristics involved in the tolerance of bivalves to marine hypoxia: Verification by inter-and intraspecific comparisons of species with different hypoxia tolerance.

Bivalves survive exposure to hypoxic water through anaerobic metabolism. However, the characteristics of anaerobic metabolism that determine the differences in hypoxic tolerance observed between and within species remain unclear. In this study, we examined three species belonging to the superfamily Arcoidea (Anadara kagoshimensis, Tegillarca granosa, and Estellacar olivacea) with differences in hypoxia tolerance as well as one species (A.

Symbiotic microbial population composition of under temperature and pesticide pressures.

Insect population control using pesticides faces new challenges as global temperatures change. Symbiotic bacteria of insects play a key role in insect resistance to pesticides, and these symbiotic bacteria themselves are sensitive to the effects of temperature changes. , a sucking pest, survives in a wide range of temperatures (15°C-35°C), and is presently controlled predominantly using the pesticide imidacloprid.

Comparative transcriptome analysis and functional verification revealed that GhSAP6 negatively regulates salt tolerance in upland cotton.

Owing to the scarcity of cultivable land in China, the agricultural sector is primarily focused on grain and oil crops. Simultaneously, the cultivation of cotton has gradually shifted towards regions characterized by elevated soil salinity levels. Additionally, the mechanism behind cotton's ability to tolerate salt remains elusive.

Effect of changes in skin properties due to diabetes mellitus on the titration period of transdermal fentanyl: single-center retrospective study and diabetic animal model study.

Background: In the dose titration of transdermal fentanyl to prevent unrelieved pain, it is important to consider not only dose adjustment, but also the titration period, which is influenced by the time required to reach the steady state. Many patients with cancer pain experience comorbidities that might affect the skin properties and influence transdermal absorption. We hypothesized that skin changes due to diabetes mellitus (DM) would affect the titration period of transdermal fentanyl.

Effects of Culture Medium Enrichment with Zinc on Astaxanthin Accumulation in a New Strain of the Microalga .

High Zn concentrations in microalgal cells that produce astaxanthin as a feed additive can reduce the symptoms of malnutrition in aquatic animals. Therefore, in this study, we analysed the effect of Zn in the culture medium on the growth of a newly isolated microalgal strain ZY24. Zn and white light stress altered the pigment content in microalgal cells.

Agronomic Biofortification of Unconventional Food Plants with Zinc.

Zinc (Zn) biofortification in food plants presents a good strategy to address inadequate Zn intake by humans, a major health concern. Unconventional food plants (UFPs), known for their rich nutritional profile, offer an accessible and nutritious alternative to the food system. This study evaluated the response of selected UFP species to Zn application.

Identifying NH emission mitigation techniques from farm to field using a Bayesian network.

This study addresses the challenge of reducing ammonia (NH) emissions from agriculture by evaluating various mitigation techniques. The research utilized a Bayesian Belief Network (BBN) to integrate quantitative data on NH volatilization reduction with qualitative stakeholder perceptions, aiming to identify the best available techniques (BATs) that balance environmental, economic, and socio-cultural factors for farmers in the Veneto region of Italy. The BBN framework established probabilistic dependencies between variables related to livestock, crop type, manure storage, fertilization management, and pedo-climatic conditions.

A new phthalide derivative from the mushroom Cyclocybe cf. erebia culture filtrate affects the phase of circadian rhythms in mouse fibroblasts.

Circadian rhythms are biological systems that provide approximately 24-hour cycles for the behavior and physiological functions of organisms. As diverse modern lifestyles often cause disturbances in circadian rhythms, new approaches to their regulation are required. Therefore, new compounds that affect circadian rhythms have been explored in edible mushrooms.

First detection of Bemisia tabaci (Hemiptera: Aleyrodidae) MED in Oklahoma and development of a high-resolution melting assay for MEAM1 and MED discrimination.

The sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is a polyphagous pest recognized as composed of several cryptic or sibling species. The Middle East-Asia Minor 1 (MEAM1) and the Mediterranean (MED) putative species are invasive and destructive worldwide. The MEAM1 is established throughout the United States, while MED is documented in 27 states.

Cotton Metabolism Regulatory Network: unraveling key genes and pathways in fiber development and growth regulation.

Cotton (Gossypium hirsutum L.) is one of the world's most important commercial crops. However, the dynamics of metabolite abundance and the potential regulatory networks throughout its life cycle remain poorly understood.

Identification and characterization of ATP-binding cassette transporters involved in chlorantraniliprole tolerance of model insect Drosophila melanogaster and agricultural pest Spodoptera frugiperda.

ATP-binding cassette (ABC) transporter family is one of the largest transporter families, which plays an important role in insecticide tolerance. In this study, we found that the ABC transporter inhibitor verapamil could significantly enhance the toxicity of chlorantraniliprole (CHL) to the model insect Drosophila melanogaster. Forty-six ABC transporter genes of D.

AgoArmet and AgoC002: key effector proteins in cotton aphids host adaptation.

Aphids are insects that feed on phloem and introduce effector proteins into plant cells through saliva. These effector proteins are key in regulating host plant defense and enhancing aphid host adaptation. We identified these salivary proteins in the cotton aphids genome and named them AgoArmet and AgoC002.

Intestinal butyric acid-mediated disruption of gut hormone secretion and lipid metabolism in vasopressin receptor-deficient mice.

Objectives: Arginine vasopressin (AVP), known as an antidiuretic hormone, is also crucial in metabolic homeostasis. Although AVP receptor-deficient mice exhibit various abnormalities in glucose and lipid metabolism, the mechanism underlying these symptoms remains unclear. This study aimed to explore the involvement of the gut hormones including glucagon-like peptide-1 (GLP-1) and microbiota as essential mediators.

GhCNGC31 is critical for conferring resistance to Verticillium wilt in cotton.

In the past decades, cyclic nucleotide-gated ion channels (CNGCs) have been extensively studied in diploid species Arabidopsis thaliana. However, the functional diversification of CNGCs in crop plants, mostly polyploid, remains poorly understood. In allotetraploid Upland cotton (Gossypium hirsutum), GhCNGC31 is one of the multiple orthologs of AtCNGC2, being present in the plasma membrane, capable of interacting with itself and binding to calmodulins and cyclic nucleotides.

Are Amphibian Eggs a Precious Food Resource for (Amphibia: Urodela) in Spring?

Most true predators are generalists, and it is difficult to examine their actual diets in the wild. In many cases, the prey that experience a large impact are also not well known. Amphibians are generalist predators that prey mainly on insects, and amphibian species active beginning in spring are considered to prey on food resources other than insects in this season due to the low number of insects.
