Body size declines are a common response to warming via both plasticity and evolution, but variable size responses have been observed for terrestrial ectotherms. We investigate how temperature-dependent development and growth rates in ectothermic organisms induce variation in size responses. Leveraging long-term data for six montane grasshopper species spanning 1,768-3 901 m, we detect size shifts since ~1960 that depend on elevation and species' seasonal timing.

As a result of climate change, global temperatures are increasing, and water scarcity is on the rise. Soybean [ () Merr] is one of the most important crops in the world due to its importance as food and feed. One of the major limiting factors for soybean production is drought, which can cause up to 80% reduction in yield.

Members of the genera Flavobacterium, Chryseobacterium and Sphingomonas constitute a group of microorganisms in the rhizosphere associated with plant growth promoting (PGP) features. A polyphasic approach was employed to ascertain the taxonomic status of five selected strains. Overall genome relatedness indices of digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) between the strains and the other members of the genera Flavobacterium, Chryseobacterium and Sphingomonas were found to be below the established thresholds, respectively.

Plasma is considered as the fourth state of matter, and atmospheric cold plasma (cold plasma) is a type of plasma consisting of ionized gases containing excited species of atoms, molecules, ions, and free radicals at near room temperature. Cold plasma is generated by applying high voltage to gases, causing it to ionize thus forming plasma. Although cold plasma has been found to break seed dormancy and improve germination rate, only a few studies have explored the potential of cold plasma against insect herbivory.

State Key Laboratory of Ecological Pest Control for Fujian and Taiwan Crops, Key Laboratory of Bio Pesticide and Chemical Biology, MOE, College of Plant Protection, Fujian Agriculture and Forestry Univ, Fuzhou, China.

The interaction of microbial communities with host immunity has become one of the most explored research areas with significant implications for pest control strategies. It has been found that the gut microbiota plays substantial roles in immune response regulation and host-gut microbiome symbiosis, as well as in pathogen resistance and overall fitness in Tephritidae fruit flies that are major pests of agricultural importance. In this review, we discuss the modulation of immune responses of Tephritidae fruit flies by the gut microbiota with particular emphasis on the general interactions between microbiota and the immune system.

Occurrence and allele frequencies of genetic variants associated with Varroa drone brood resistance (DBR) in African Apis mellifera subspecies.

J Invertebr Pathol

January 2025

Laboratory of Molecular Entomology and Bee Pathology (L-MEB), Department of Biochemistry and Microbiology, Faculty of Sciences, Ghent University, Ghent, Belgium.

The ectoparasite Varroa destructor is a major contributor to the global decline of honeybee colonies (Apis mellifera), especially in the Northern Hemisphere. However, Varroa-resistant honeybee populations have been reported in various regions around the globe, including Europe and Africa. This resistance is primarily attributed to the trait known as Suppressed Mite Reproduction (SMR), which significantly reduces the reproductive success of Varroa mites within these colonies.

Glyphosate is a non-selective herbicide widely used in agriculture, and its overexposure poses significant health and environmental risks. Herein, a novel Cu-coordinated fluorescent sensing system (HYBC-Cu system) based on acylhydrazone groups was designed, capable of glyphosate-specific recognition. The HYBC-Cu system was constructed with simple steps, with the advantages of short recognition time (< 1 min), good specificity, anti-interference, and excellent sensitivity (LOD = 95 nM).

A comprehensive study was conducted on the life history parameters of an important vector Culicoides oxystoma Kieffer (Diptera: Ceratopogonidae), to standardize potential rearing procedures. Data on life history traits and rearing conditions are crucial for establishing laboratory colony and conducting vector competence-based studies utilizing specimens with a known rearing history. Six different substrate compositions were used to rear the larvae: S1: habitat mud containing cattle manure + nutrient broth + yeast, S2: yeast, S3: habitat mud containing cattle manure + nutrient broth, S4: nutrient broth, S5: sterile (habitat mud consisting cattle manure + nutrient broth + yeast) and S6: tap water.

Cricket song recognition is thought to evolve through modifications of a shared neural network. However, the species has an unusual recognition pattern that challenges this view: females respond to both normal male song pulse periods and periods twice as long. Of the three minimal models tested, only a single-neuron model with an oscillating membrane could explain this unusual behavior.

Strongyloidiasis is a parasitic nematode infection mainly caused by Strongyloides stercoralis. Immunocompromised conditions, particularly cancer patients treated with chemotherapy and corticosteroids, have a significant risk of developing Strongyloides hyperinfection. The lack of a gold standard laboratory method to rule out this infection and the insensitivity of microscopic stool examination due to low and intermittent larvae output in stool contribute to the low detection rate of this infection.
