ABSTRACT Ceracris nigricornis Walker is an insect of the Acrididae, which can harm bamboo, rice, corn, sorghum and other crops, cause serious economic losses. In this study, based on 234 occurrence sites C. obtained from Global Biodiversity Information Facility literature, data three future climate scenarios presented by CMIP6, two niche models (GARP, MaxEnt) were used to predict suitable area in China. The result shows that main environmental factors affecting distribution are min temperature coldest month (bio6), mean quarter (bio11), precipitation driest (bio14) wettest (bio16). From MaxEnt model, it be seen China 128.91 × 10 4 km 2 under current scenario.

The pine caterpillar (Dendrolimus spectabilis Bulter, Lepidoptera: Lasiocampidae) is a destructive insect threatening forest communities across Eurasia. pest polyvoltine, and under global warming, more favorable temperatures can lead to additional generations. Here, we simulated the voltinism current future climatic scenarios based on thermal physiology cumulative growing degree day (CGDD) model. Subsequently, revealed change patterns of along elevational latitudinal gradients. results showed that both CGDD are increasing. ranges from 1.26 1.56 generations (1.40 ± 0.07), with an increasing trend 0.04/10a. Similar trends expected continue climate scenarios, values 0.01/10a, 0.05/10a, 0.07/10a, 0.09/10a for SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5 respectively. At elevation gradients, increases all ranges, peaking at 500–1000 m latitudes 34–34.5° N. This study highlights increase in not limited low-elevation -latitude regions but predicted various elevations latitudes. These findings enhance our understanding how affects contribute management strategies, although this assumes linear relationship between temperature voltinism, without considering other ecological factors.

The pygmy grasshopper, Zhengitettix transpicula, is a Chinese endemic species with an exceedingly limited distribution and fragile population structure, rendering it vulnerable to extinction. We present high-continuity, chromosome-scale reference genome assembly elucidate this species’ distinctive biology inform conservation. Employing integrated sequencing approach, we achieved 970.40 Mb 96.32% coverage across seven pseudo-chromosomes impressive continuity (N50 > 220 Mb). Genome annotation achieves identification 99.2% BUSCO completeness, supporting quality. Comparative analyses 14 genomes from Orthoptera-facilitated phylogenomics revealed 549 significantly expanded gene families in Z. transpicula associated metabolism, stress response, development. However, genomic analysis exposed remarkably low heterozygosity (0.02%), implying severe genetic bottleneck small, fragmented populations, characteristic of extinction environmental disruptions. Elucidating the basis dynamics specialization provides imperative guideline for habitat conservation restoration rare organism. Moreover, divergent evolution CYP305m2 regulating locust aggregation highlighted potential structural hence functional variations between Acrididae Tetrigidae. Our chromosomal characterization advances Orthopteran resources, establishing framework evolutionary developmental explorations applied genomics, reversing trajectory unique grasshopper lineage towards oblivion.
