1. {"_":"Multi-Plant Screening and Controlled Evaluation of Two Selected Plant Species Against (Meyrick).","i":["Tuta absoluta"]}
PMID:日期:2026-09-21is an invasive species that has managed to expand beyond its native geographical area and causes severe yield losses in tomato. Despite the application of synthetic insecticides in getting rid of the pest, farmers have reported reduced efficacy over the course of time due to resistance. With regard to ecological pest management approaches, studies regarding the use of companion plants in the management of are scarce. Therefore, we screened fourteen potential companion plants for repellency using a Y-tube olfactometer followed by cage and screenhouse experiments. Data were analyzed using R software (version 4.6.0; R Core Team, 2026). The screening results showed that and significantly repelled compared to other potential companion plants at < 0.001. In a dual-choice cage experiment, tomato plants placed with and were recorded to have lower leaf damage percentages of 47.27% and 33.94%, respectively, compared to the negative control (66.34%). Similarly, tomato plants intercropped with and showed lower leaf damage percentages of 13.92% and 25.00%, respectively, compared to the negative control (63.38%) under the screenhouse experiment. Therefore, and exhibit significant potential in the management of in tomato.

2. {"_":"Fruit Pulps Enhance Longevity and Parasitism of , a Pupal Parasitoid of Drosophilid Flies.","i":["Trichopria drosophilae"]}
PMID:日期:2026-09-21is a cosmopolitan pupal parasitoid of drosophilid pests, including the globally destructive . Improving parasitoid fitness through nutritional supplementation is a promising strategy for biological control, yet the suitability of field-available food resources remains largely unexplored. Here, we assessed how adult diet influences longevity, survival, parasitism, offspring production, and sex ratio of . Seven dietary treatments were tested: water control, 10% honey solution, banana pulp, blueberry pulp, cherry pulp, flowers alone, and flowers plus water. Fruit pulps, especially cherry, dramatically prolonged adult longevity to over 28 days, matching or surpassing the honey standard. Wasps fed flowers alone survived only approximately five days; however, providing water together with flowers restored survival to a level comparable to the water control, indicating that water deprivation was an important (at least partial) cause of this short lifespan, and no evidence was found that flowers provide accessible nectar. In a density-dependent parasitism assay across six host densities (5-30 pupae), a significant diet-by-density interaction was detected: parasitism rates were low at low host densities and increased with host density, whereas at intermediate and high densities (15-30 hosts), fruit-fed wasps parasitized significantly more hosts than the water control (blueberry at 15 hosts; banana at 20 hosts; all three fruit treatments at 25 and 30 hosts). Across all densities, fruit-fed wasps parasitized significantly more hosts overall than those receiving water or honey alone. Consistently, total offspring and female emergence were greater in fruit-fed groups than in water-fed wasps. Offspring sex ratio was unaffected by diet. These results demonstrate that fruit pulps are highly effective nutritional resources that enhance both survival and reproductive success of in a density-dependent manner, whereas flowers alone are insufficient to sustain parasitoid survival. Our findings highlight the potential of fruit resources as natural food subsidies for parasitoids and underscore the need to consider floral accessibility when selecting plants for conservation biological control.

3. Vegetation and Soil Surface Arthropods in Mediterranean Vineyards with Different Interrow Cover Crop Combinations.
PMID:日期:2026-09-21Interrow cover crops have been increasingly adopted in Mediterranean vineyards to improve soil conservation and other ecosystem services. However, their long-term effects on vegetation dynamics and soil surface arthropod communities remain poorly understood. A study was conducted over three sampling years (2017, 2018 and 2023) in the Douro Demarcated Region (northeastern Portugal) to evaluate, one, two, and seven years after establishment, differences associated with two sown cover crop mixtures, namely a sown legume mixture (LEG) and a sown mixture of legumes and grasses (LEGRA) and spontaneous vegetation (SPONT) in vegetation dynamics and the activity density, richness, diversity, and stability of soil surface arthropod communities. Vegetation was assessed through floristic surveys, and arthropods were sampled using pitfall traps. Vegetation composition and soil surface arthropods community structure varied among sampling years, indicating that temporal variation also contributed to differences in both communities. LEG consistently maintained the highest vegetation cover, whereas LEGRA showed the lowest plant richness. Despite species turnover, LEG and LEGRA retained their functional identity, while SPONT exhibited greater temporal variation in floristic composition. Cover crop treatments were associated with differences in soil surface arthropod activity density, diversity, and community stability. LEGRA showed the highest activity density, whereas higher diversity and evenness were observed in LEG. SPONT presented intermediate values, differing significantly from LEGRA only in Shannon Wiener diversity index. All treatments maintained a relatively balanced trophic structure, suggesting a potential for natural regulation of herbivore population. Vegetation cover and plant richness were positively associated with soil surface arthropod diversity, highlighting the importance of vegetation characteristics for that communities in Mediterranean vineyards.

4. {"_":"Host Plant Trichome Architecture Mediates the Predatory Efficacies of and Against .","i":["Nesidiocoris tenuis","Chrysoperla carnea","Tuta absoluta"]}
PMID:日期:2026-09-21The tomato leafminer, , is a globally important pest that causes severe losses in tomato production, and effective biological control strategies are increasingly needed due to widespread insecticide resistance. The effectiveness of natural enemies is influenced by plant structural traits, such as trichomes, which create complex microhabitats that shape predator-prey interactions. Here, we compared the predatory performances, plant-level control efficacies, and predator-plant interactions of two widely used biological control agents, and , against eggs on tomato and eggplant. In laboratory assays, predation capacity increased with predator developmental stage, with adult female and third-instar larvae of exhibiting the highest species-specific predation rates. However, in whole-plant and semi-enclosed cage experiments, maintained substantial foraging activity, effectively suppressing on tomato plants, whereas showed limited control efficacy, with 86.7% of larvae abandoning plants within 24 h. Conversely, exhibited significantly higher predation rates than on eggplant, with minimal abandonment. Comparing plant surface architectures revealed that tomato leaves possessed substantially longer trichomes than eggplant leaves (4.14 vs. 0.48 mm), which restricted the foraging activity of . Our results indicated that remains the preferable agent for tomato, while is highly suitable for short-trichome-bearing solanaceous crops like eggplant. Crop surface characteristics strongly influence biological control effectiveness, and matching predator traits with crop architecture will improve the success of natural enemy-based pest management.

5. {"_":"Transcriptome Analysis and Characterization of Two Detoxification Genes Responding to Imidacloprid in .","i":["Aphis spiraecola"]}
PMID:日期:2026-09-21is a major pest of fruit trees worldwide, causing significant yield reductions and economic losses in apple production. Chemical control remains the primary and most effective method for managing in the field. Imidacloprid, the first neonicotinoid insecticide, effectively targets piercing-sucking pests. However, the time-dependent response of to imidacloprid exposure has not been well characterized. In this study, we assessed the susceptibility of an population from Zhengzhou to imidacloprid. Enzymatic assays revealed that the activities of cytochrome P450s, glutathione S-transferases (GSTs), and carboxylesterases (CarEs) were significantly increased following imidacloprid treatment. A synergism assay further demonstrated that the P450 inhibitor PBO and the CarE inhibitor TPP significantly enhanced the imidacloprid toxicity against . Transcriptome analysis revealed that LC imidacloprid treatment induced time-dependent changes in gene expression at 12, 24, and 36 h. A total of 46 P450 genes, 42 esterase genes, and six GST genes were identified in the transcriptome of . Five detoxification enzyme genes, , , , , and , were significantly overexpressed, as confirmed by both transcriptomic and qPCR analysis. Moreover, RNAi-mediated knockdown of and substantially increased aphid sensitivity to imidacloprid compared with the ds control group. These results demonstrate that and play an important roles in determining susceptibility to imidacloprid. Our findings provide a theoretical basis for the rational and scientific use of imidacloprid in aphid management.

6. {"_":"Stage-Specific Mortality and Developmental Effects of Synthetic Insecticides, Entomopathogenic Fungi, and Physical Barrier Agents on (Neuroptera: Chrysopidae): Implications for Biological Control in Avocado Orchards.","i":["Chrysoperla carnea"]}
PMID:日期:2026-09-21Pesticide contamination of agroecosystems poses significant risks to non-target arthropods, including natural enemies that provide essential pest regulation services. Assessing the ecotoxicological impact of reduced-risk pesticides on beneficial predators is therefore critical for both environmental safety and sustainable agriculture. This study evaluated the lethal and sublethal ecotoxicological effects of six pesticide formulations-abamectin, deltamethrin, paraffinic oil, potassium soap, and the entomopathogens and -on second-instar larvae, third-instar larvae, pupae, and adults of the lacewing under laboratory conditions using topical exposure. Corrected mortality was calculated using Abbott's formula. Developmental duration and adult longevity were assessed to detect sublethal effects. According to International Organisation for Biological Control classification standards, L2 larvae were the most susceptible stage, where paraffinic oil was moderately harmful, abamectin and were classified as slightly harmful, and deltamethrin was harmless. In pupae, only deltamethrin was slightly harmful, while the remaining treatments were harmless. In adults, paraffinic oil was moderately harmful and abamectin was slightly harmful, whereas potassium soap and both entomopathogens were harmless. Sublethal effects included a significant prolongation of the L2 developmental stage across all treatments and reduced adult longevity following larval exposure to deltamethrin. Overall, L3 larvae and pupae were the most tolerant stages. These results identify potassium soap and the entomopathogens as the most compatible options with , supporting their inclusion in IPM programmes for avocado orchards, while highlighting the environmental risk posed by paraffinic oil and abamectin to early larval stages and adults of this ecologically important predator.

7. {"_":"Body Size-Related Thermal Acclimation and Underlying Gene Expression Mechanisms in Workers of the Red Fire Ant .","i":["Solenopsis invicta"]}
PMID:日期:2026-09-20Body size is a critical trait shaping ectotherm thermal tolerance, yet how body size mediates thermal acclimation remains poorly understood in insects. Here, we conducted 15-day daily cold (9 °C, 2.5 h) and heat (30 °C, 2.5 h) acclimation treatments on large, medium, and small workers, followed by extreme temperature survival assays and comparative RNA-seq transcriptome profiling to uncover size-dependent acclimation phenotypes and molecular regulatory pathways. Survival results revealed that both cold and heat acclimation significantly boosted extreme thermal resistance of medium and small workers, whereas large workers exhibited inherently low mortality under lethal temperatures with no significant acclimation-induced survival improvement. Transcriptomic analyses showed striking body-size-specific transcriptional reprogramming: medium workers produced the largest number of differentially expressed genes (DEGs) under both acclimation regimes, followed by large workers, while small workers displayed minimal transcriptional shifts. Functional enrichment highlighted core pathways including lipid and small-molecule cryoprotectant metabolism, cuticle/membrane homeostasis, ion transport, antioxidant detoxification and sensory nervous signaling. Notably, hundreds of odorant receptor genes were sharply downregulated in acclimated medium workers, suggesting potential repression of olfactory function. Unlike acute thermal stress, long-term repeated acclimation triggered only mild transcriptional fluctuations of heat shock proteins with limited fold changes. Our findings demonstrate that thermal acclimation capacity in red fire ant workers is strongly correlated with body size, and coordinated remodeling of metabolic, osmotic, and chemosensory gene networks underpins this thermal plasticity. This body-size-dependent acclimation mechanism advances our understanding of invasive ant climate adaptation and helps predict their range expansion risks under global warming.

8. Exploring and Mitigating Insecticide Resistance in Urban Pests with New Synergists and Insecticides.
PMID:日期:2026-09-20This review summarizes the impact of insecticide resistance in urban pests and its implications for 'One Health' systems. Mosquitoes are the major vector of human disease via blood feeding, followed by houseflies and cockroaches via physical contact, and finally bed bugs, ants, and termites, which are not typically disease vectors. Besides overt disease, other impacts in the context of One Health include nuisance biting and resultant infections, as well as allergic reactions. Control of urban pests is still primarily achieved with insecticides, which have continually improved over time. However, their use has selected for the evolution of resistance to several compound classes across broad geographical areas and multiple species. Resistance results from several types of mechanisms: altered inherited behavioral repertoires that reduce chemical exposure, modified target sites, increased metabolism, and reduced penetration, which have recently been shown to have several specific underlying causes. Overall, the literature portrays a complex resistance landscape that highlights the importance of comprehensive, multifaceted approaches to maintain effective control. New technologies and approaches for resistance management are also discussed, with emphasis on improved chemical control measures via novel synergists and insecticides from both natural and synthetic sources.

9. {"_":"High Pyrethroid Resistance in Is Strongly Associated with Variants: A Multiplex High-Resolution Melting Tool for Vector Surveillance.","i":["Triatoma infestans","kdr"]}
PMID:日期:2026-09-20is the main vector of in the Southern Cone, where vectorial transmission of Chagas is still occurring despite control campaigns with pyrethroid insecticides. High pyrethroid resistance was detected in populations from Argentina and Bolivia. This raises the urgent need for including strategies for monitoring and management of insecticide resistance as an essential component of control campaigns. Voltage-gated sodium channels are the target site of pyrethroids; non-silent single-nucleotide polymorphisms in specific sites of the gene encoding this channel, called kdr mutations, are associated with resistance to pyrethroids in many insect species, including . The early detection of kdr in a population allows taking control decisions timely. In this work, we present the development of a high-throughput assay based on multiplex high-resolution melting for genotyping kdr variants in this species. We characterized populations according to their toxicological response to deltamethrin and efficiently used this assay for genotyping. Our results indicate that high resistance to pyrethroids is closely related to the presence of kdr variants in and they provide a high-throughput method for vector surveillance and resistance management.

10. Functional Morphological Differentiation Associated with Dung-Relocation Strategies in True Dung Beetles (Coleoptera: Scarabaeinae).
PMID:日期:2026-09-20Understanding how ecological diversification translates into morphological differentiation is central to explaining the evolution of organismal form and function. True dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) exhibit diverse resource-use strategies, mainly including tunneling and rolling behaviors, which impose different functional demands on locomotion, excavation, and dispersal. However, it is unclear whether these ecological differences are consistently associated with differentiation in functional traits, particularly across different body-size classes. Here, we compared five dung beetle species representing large and small tunnelers, large and small rollers, and a mixed-strategy species using external structural traits, functional trait analyses, principal component analysis, and allometric modeling. Allometric analyses indicated that most functional traits exhibited similar scaling relationships among species after false-discovery-rate correction, suggesting that structural differentiation was not primarily driven by body-size differences. Functional morphological analyses revealed clear differentiation among species with contrasting resource-use strategies, with variation mainly associated with foreleg proportions, hindleg elongation, and wing morphology. Size-matched comparisons further showed that rollers consistently possessed relatively longer hindlegs and more elongated hind-tibiae than tunnelers across body-size classes, whereas foreleg proportions and protibial structures displayed more variable patterns. The mixed-strategy species exhibited a mosaic combination of traits rather than strictly structural dependencies. These findings demonstrate that dung-relocation strategies are associated with different coordinated functional trait differentiation, highlighting a potential trade-off between excavation-related and locomotion/dispersal-related specialization.
