However, there is a lack of reports on the impacts of different wavelengths of silicon-based LED lights on its population dynamics and age-stage two-sex life table. This study aims to form an age-stage two-sex life table to evaluate the effects of nighttime LED light with 4 different wavelengths (red [630 ± 2.5 nm], yellow [568 ± 2.5 nm], blue [460 ± 2.5 nm], and green [535 ± 2.5 nm]) on FAW growth, development, and fecundity. The results revealed that the survival rate of pupae was the lowest under blue light treatment. Blue and green light therapy dramatically reduced the fecundity of FAW, and exposure to green light increased the adult preoviposition period (APOP), the total preoviposition period (TPOP), and the longevity of the adult. Moreover, among the 4 different wavelengths of light, the net reproductive rate (R0), intrinsic rate of increase (r), and finite rate of increase (λ) of FAW were the greatest under red light and significantly decreased under green and blue light, the longest mean generation time (T) occurred under green light. Our results suggest that blue and green light are beneficial for preventing and controlling FAW. These findings may help provide new pest control strategies to improve pest control and reduce agricultural economic losses.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"1115-1125"},"PeriodicalIF":0.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144059105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its spread is influenced by various factors, including environmental factors and anthropogenic factors, and the available data on pest spread and the influencing factor has nonlinear relationship. Additionally, the collection of pest data is often constrained, resulting in small datasets, a lack of long-term time series data, and issues such as missing data and anomalies. Traditional model-driven approaches have limitations in handling nonlinear relationships and high-dimensional data, while data-driven methods often lack interpretability and are prone to overfitting, ultimately leading to insufficient prediction accuracy. Therefore, this paper proposes the MLP-LR method, which combines logistic regression (LR) with a multilayer perceptron (MLP) to overcome these limitations. The model also used the Bayesian adaptive lasso method to select important influencing factors, that further improved the prediction accuracy. Based on H. cunea occurrence data in China, the current study demonstrated the stability and accuracy of the MLP-LR model on small datasets. The results showed that compared to traditional LR models and MLP independently, MLP-LR performs better in predicting the spread of H. cunea, effectively addressing the shortcomings of traditional methods. This study provides a new tool and perspective for forecasting and early warning of H. cunea outbreaks, offering important references for future research and its applications in the field.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"1156-1173"},"PeriodicalIF":0.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144059340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Insecticidal assays demonstrated that all treatments achieved over 90% mortality; however, wood ash treatments exhibited greater variability, suggesting a dependence on concentration and environmental conditions. Probit modeling estimated that mortality increased by a factor of 2.77 with each concentration doubling. Analysis of variance indicated that neither temperature, nor relative humidity significantly affected lethal concentrations (LC50 and LC90). Notably, the diatomaceous earth product SilicoSec achieved consistent results at lower concentrations than currently recommended, suggesting potential for reduced application rates. Progeny emergence studies revealed that treatment efficacy was influenced by temperature and relative humidity, with higher temperatures and lower humidity levels enhancing mortality. Beta regression analysis confirmed that treatments and temperature significantly affected the proportion of dead beetles, whereas relative humidity and concentration did not. These findings underscore the importance of selecting appropriate treatment combinations and storage conditions to effectively control S. granarius populations.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144287664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite extensive research on aphid behavior and pest management, the specific mechanisms driving host adaptation in M. persicae remain inadequately explored. This review addresses this critical knowledge gap by examining the genetic, behavioral, and physiological mechanisms that enable M. persicae to adapt to various host plants. The formation of biotypes through genetic adaptation, including color polymorphism and detoxification processes, is explored as a key factor in the pest's survival and proliferation. Additionally, we analyze the behavioral strategies M. persicae employs in host selection and feeding preferences, influenced by host plant traits. Physiological adaptations, such as changes in digestive enzymes and life cycle modifications, further contribute to the aphid's capacity to overcome plant defenses. The review also considers the impact of environmental and host plant factors on these adaptations, providing a comprehensive understanding of the complex interactions between M. persicae and its hosts. By integrating these insights, the review proposes implications for the development of more targeted and sustainable pest management strategies. This work enhances our understanding of host adaptation in M. persicae and underscores the need for novel approaches in controlling this resilient pest, ultimately contributing to the advancement of integrated pest management (IPM) practices.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144217954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Korea Forest Service recommends the use of pheromone traps to monitor the spread of this insect vector. However, to improve the accuracy of occurrence monitoring and enhance control through mass trapping, it is necessary to increase the capture efficiency of pheromone traps. In this study, we evaluated various pheromone trap conditions to improve the attraction efficiency of M. saltuarius by modifying trap color, enantiomers, and the release rates of pheromone and kairomones. Among the 6 tested colors (black, red, green, blue, yellow, and white), M. saltuarius exhibited the most potent attraction to black traps. In enantiomer preference tests, M. saltuarius showed no significant difference in response to the enantiomers of α-pinene and limonene. To evaluate the effects of pheromone and kairomone release rates on the capture of M. saltuarius, traps were baited with varying release rates of each compound-monochamol (5.7 to 28.5 mg/day), ethanol (15.9 to 79.5 mg/day), α-pinene (18.1 to 90.5 mg/day), and ipsenol (5.9 to 29.5 mg/day)-and the number of captures was compared.

A transinfection of the endosymbiont Rickettsiella viridis into a line of the novel host Myzus persicae has previously shown large deleterious effects on aphid fitness and rapid spread in caged aphid populations under a cool environment. Because host clones can significantly influence endosymbiont effects and fitness-related traits more generally, it is important to test endosymbiont effects across a range of genotypic backgrounds. Here, we developed four Rickettsiella transinfected lines in different M. persicae clones via hemolymph microinjection, including clones with relatively high pesticide resistance. All four lines exhibited consistent fitness costs, reflected in reductions in both fecundity and longevity and reduced heat tolerance, although the magnitude of these effects varied among clones. The lines also resulted in stable and similar shifts in body color, with infected aphids being darker in color, although clonal effects were again observed. Vertical transmission was stable in all clones, and Rickettsiella infection was also shown to be transmitted horizontally between aphid pairs within Petri dishes in each clone. These results demonstrate consistent transmission and deleterious fitness effects of Rickettsiella transinfections, while also highlighting genetic background effects.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144145255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These include lepidopteran larvae which infest sorghum heads (headworms) and have historically been managed by insecticide applications. The aphid pest Melanaphis sorghi (Theobald) has more recently emerged as an economic pest of sorghum leaves. Management for this aphid has included host plant resistance, insecticide applications, and suppression from insect natural enemies. It is currently unclear if the management practices for M. sorghi or headworms interferes with suppression of the other pest or natural enemies in sorghum. A 2-yr field study was conducted in grain sorghum to assess the impacts of an aphid resistant sorghum, insecticide applications for M. sorghi, and insecticide applications for headworms on pests, natural enemies, and sorghum cultivation in Mississippi. The results indicated that all management strategies could significantly reduce pest densities and conserve suppression from resident natural enemies. No significant benefits were identified from the combined management of both pests compared to managing each individually. The yield and economic returns from the insect control costs indicated that while pest densities were significantly reduced, other factors impacted sorghum production under the environmental conditions and pest pressures experienced during this study. This research demonstrated the feasibility of integrating multiple management tactics for aphids and headworms. This has the potential to enhance the efficiency and efficacy of sorghum integrated pest management, although it may not always be necessary.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144136533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the threat to other legume crops and potential for host plant resistance for M. morrisella management in G. max is unknown. Thus, M. morrisella host range among different species of legume crops and genotypes of G. max were evaluated through complementary choice and no-choice experiments. Macrosaccus morrisella oviposited on its native host American hogpeanut (Amphicarpaea bracteata (Fabales: Fabaceae)) and G. max (both grain and vegetable types), but not on Phaseolus vulgaris, Vigna unguiculata, Cicer arietinum, Vicia faba, Pisum sativum, and Lens culinaris (Fabales: Fabaceae). Low oviposition was observed on Vigna radiata and Phaseolus lunatus (Fabales: Fabaceae) in a choice test, but no larvae survived on either legume. When G. max genotypes were compared, lower but detectable oviposition (50 to 100 eggs per plant) was observed on PI229358 and PI227687 in choice and no-choice tests, and lower survival rates (20 to 40%) on PI229358 and M15-105140 in a no-choice test. These results indicate that M. morrisella host range appears to be restricted to the previously known native hosts and G. max, but continued monitoring for adaptation to other legumes and further studies testing multiple populations of M. morrisella are necessary.
