We modelled the annual distribution and expansion of <i>D. kuriphilus</i> using SDMs. Three climate datasets: regional interpolations, temporally explicit CHELSA time series, and long-term CHELSA averages, were compared to test their influence on model accuracy. Habitat suitability was estimated with GLM, MaxEnt, and Random Forest, and model performance was evaluated with the Boyce index. Temporal transferability was assessed by projecting early-year models to subsequent years and analysing accuracy patterns via multifactorial ANOVA. Model accuracy, measured with the Boyce index, improved over time, surpassing 0.7 for most datasets and algorithms. Differences among climate datasets were minor, although regional data slightly enhanced early predictions. MaxEnt consistently achieved the highest and most stable performance, while Random Forest and GLM were more variable. Models projected beyond their calibration years rapidly lost predictive power, showing limited temporal transferability. ANOVA confirmed that neither climate dataset nor algorithm significantly influenced accuracy, though MaxEnt performed best overall. SDMs are valuable tools for invasive species management when used adaptively. Accuracy improves with more occurrence data but declines when projecting future expansion, highlighting the need for regular updates.

We used occurrence and climate data to predict the distribution of <i>Apis mellifera</i> in the Doce River Basin, south-east Brazil, under baseline and future scenarios (2050). Given the high prevalence of apiculture in the basin, where it supports local livelihoods and contributes to the regional economy, anticipating these shifts is important for adapting beekeeping and pollination-dependent production to future climates. We also quantified how much of the projected climate-suitable area overlaps the spatially explicit mining tailings footprint associated with the 2015 Samarco dam collapse. Despite <i>A. mellifera</i>'s plasticity and wide distribution, our models project a 38% reduction in climate-suitable area across the basin under future scenarios. In contrast, the climate-suitable area within the mining tailings footprint is projected to decline only 8% from baseline to future scenarios, indicating comparatively higher stability within that restricted subset of the basin. Importantly, because <i>A. mellifera</i> is managed, occurrence records may partly reflect hive placement, and our analysis does not isolate a causal ‘dam effect’ on suitability. Beyond riparian vegetation recovery, restoration strategies should promote native pollinators by providing floral and non-floral resources, increasing nesting site availability, and reducing pesticide use, strengthening native pollination services and reducing the likelihood of managed honeybees becoming overly dominant in sensitive or recovering habitats.

The species was first detected in southwestern Spain in 2014 and has spread significantly in recent years, recently reaching the semi-arid southeast.

In general, the climatic characteristics of invaded areas in the Iberian Peninsula are similar to those of other invaded regions and the species' native range. However, notable climatic differences exist between the southeastern and southwestern invaded areas in the Iberian Peninsula, mainly related to precipitation.

In Bangladesh, superworm growers commonly use wheat bran supplemented with vegetables for rearing; however, information on the most suitable vegetable for mass production is still lacking. To find the best vegetable supplement, a laboratory study was conducted to evaluate the effects of six vegetables viz. cucumber, pumpkin, bottle gourd, pointed gourd, snake gourd and radish with wheat bran (WB) as main feed.

Si supplementation significantly reduced larval growth, fecundity, and digestive efficiency without causing physical damage to mandibles or gut tissues. Integrated metabolomic analyses of maize leaves and larval frass, together with midgut transcriptomes revealed that Si-induced chemical defences, notably elevated benzoxazinoids and flavonoids, impose strong physiological stress on larvae. Frass metabolomic analysis showed the accumulation of toxic secondary metabolites, including DIMBOA, quercetin, and chlorogenic acid, whereas Si enhanced the correlations between leaf and larval frass alkaloids, suggesting a disruption of detoxification capacity. Transcriptomic and enzymatic assays further confirmed widespread suppression of cytochrome P450s, glutathione S-transferases, and mixed-function oxidases, creating a detoxification bottleneck and disrupting metabolic homeostasis. These findings demonstrate that Si-mediated resistance operates primarily through chemical defences that overwhelm insect detoxification capacity, thereby destabilising larval metabolism.
