Summary: This study investigates the cold and heat tolerance of Bactrocera tau, an invasive pest that affects vegetables and fruits. The results show that B. tau has a wide temperature threshold for survival, which contributes to its successful establishment and expansion. The study also quantifies the tolerance potential of B. tau at different life stages.

Summary: This article reviews chilling injuries in chill-susceptible insects and cold-induced immune activation in the model dipteran Drosophila melanogaster. It also proposes a conceptual model linking biochemical and molecular causes of immune activation to its consequences during and following cold stress.

Summary: A transgenic maize carrying three exogenous genes has been developed to protect against insects and weeds. The transgenic maize showed strong toxicity against three major species of Lepidoptera insects and exhibited high tolerance to glyphosate. It has been confirmed that the three genes were successfully expressed in various tissues at different developmental stages of the transgenic maize.

Summary: Understanding the impact of environmental disturbances on insects, such as temperature exposure, is crucial for predicting their distribution and ecology in the face of climate change. Research on subterranean termites exposed to different temperature treatments revealed that cold pre-exposure prolonged activity but caused freezing at higher temperatures, with high temperature exposure showing the most deleterious effects on termite survival and ability to withstand cold stress. Furthermore, the microbial community of termites exposed to high temperatures displayed reduced richness and relative abundance of certain bacteria, highlighting the potential link between gut bacterial symbionts and termite's physiological response to environmental changes.

Summary: The electrolyte leakage method is widely used in assessing plant tissue cold hardiness, with standardizing raw data proving to be crucial for reliable estimation of cold hardiness at the species level and across diverse systems. The use of liquid nitrogen control enhances the consistency and realism of the method, especially for very cold hardy samples. Data from studies using this control method can still be compared to previously published data when standardized using the best-performing approach.

Summary: The study introduces an improved gnomonic approach for estimating natural mortality in different life stages of marine stocks using the gnomonicM package. This package offers deterministic or stochastic approaches to estimate M rates and allows for the incorporation of auxiliary information for calibrating estimates. The gnomonicM package provides a reliable and versatile tool for estimating natural mortality and can be applied to various ontogenetic developmental stages.

Summary: The fall armyworm is a polyphagous insect pest, preferring maize but also able to complete its life cycle on sorghum and wheat. Rice is a non-preferred host plant for fall armyworm. Larval diets significantly impact development time, fecundity, and survival rates of the insect. Maize is found to be the most suitable diet for fall armyworm based on the study's findings.

Summary: This study demonstrated relative fitness and phytochemical responses in six herbicide-resistant weeds and their susceptible counterparts, showing significant differences in viability, fecundity fitness, and phytochemical composition between the two. Fitness costs were observed in some herbicide-resistant weeds, but not in others. The results suggest that (-)-loliolide may act as a phytochemical cue to explain the fitness costs of herbicide-resistant weeds.

Summary: This study evaluated the effects of cold storage after acclimation on the fitness of H. hebetor. The results showed that cold storage had no significant effect on the offspring fitness. It is recommended to use unrefrigerated males or to avoid simultaneous cold storage of males and females for effective pest control.

Summary: Insecticide resistance is often associated with fitness costs, which are influenced by environmental and ecological factors. This study investigated how host plants can affect the fitness costs of insecticide resistance in Spodoptera frugiperda. The results showed that the fitness costs of spinetoram resistance in S. frugiperda depend on the host plants that S. frugiperda larvae fed on.

Summary: The risks of energy reserve depletion and encountering low temperatures can limit the winter survival of mosquito populations. Autumn females have sufficient lipid reserves for overwintering, but high metabolic rates during flight may lead to rapid depletion of these reserves. The cold hardiness of females is weaker for above-ground habitats, but sufficient for overwintering in most underground spaces.

Summary: Over 100 years of research on Drosophila melanogaster and related species have led to key discoveries in genetics, genomics, and evolution. Recent advances in long-read sequencing have enabled the generation of high-quality genome assemblies for tens or even hundreds of species. Utilizing Oxford Nanopore sequencing, a community resource of genome assemblies for 101 lines of 93 drosophilid species has been built, providing highly contiguous and complete genomes with high accuracy in coding regions.

Summary: This study tracked the changes in energy metabolism of diapausing larvae under cold and warm acclimation conditions, finding that energy metabolism changes in the cold-acclimated group facilitate the development of cold hardiness, while the high metabolic activity in the warm-acclimated group may lead to premature mortality.

Summary: This study identifies and quantifies multiple cryoprotectants in larval tissues of a subarctic fly, which could inspire the development of laboratory cryoprotectant formulations for cryopreservation. The artificial mixtures of cryoprotectants mimic the concentrations in hemolymph of freeze-tolerant larvae and exhibit cryoprotective effects. The study also suggests that trehalose stimulates the transition to the amorphous glass phase, while proline forms a layer of dense viscoelastic liquid, both protecting macromolecules and cells from thermomechanical shocks associated with freezing.

Summary: This study reveals that exposing diapausing larvae of the drosophilid fly to dry conditions significantly improves their freeze tolerance. The metabolomics analysis shows that environmental drought, decreasing ambient temperatures, and short days trigger similar metabolic rearrangement and improved larval freeze tolerance. Transition to metabolic suppression represents a common axis of metabolic pathway reorganization towards accumulation of cytoprotective compounds and stimulation of freeze tolerance.
