We investigated the impact of a synthetic predator pheromone on potato tuber yield and its underlying mechanisms within a Colorado potato beetle, Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae), and predatory stink bug, Podisus maculiventris Say (Hemiptera: Pentatomidae), system. Previous studies demonstrated that releasing the predator pheromone reduces beetle abundance and herbivore damage, and we tested whether this translated into increases in yield. We then tested the mechanisms through which the predator pheromone could increase yield. In addition to the prey responding to predator cues, we tested 2 additional hypotheses: that the pheromone influences predator abundance and plant responses, both potentially contributing to beetle suppression and yield improvement. Over 2 field seasons, pheromone-treated plots showed a 13% increase in tuber yield and fewer Colorado potato beetle larvae, suggesting yield improvement is correlated to reduced beetle abundance. Field observations indicated that stink bug predator densities were too low to significantly impact beetle populations. Instead, in lab experiments, we found that plants exposed to the pheromone flowered earlier and exhibited induced resistance, reducing larval feeding. These findings demonstrate that predator cues can enhance crop yields by influencing both plant and prey responses, highlighting their potential use in integrated pest management.</p>","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144063661","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.

Although B. mucronatus causes relatively minor damage in European and Asian forests, its threat to coniferous forests is similar to that of Bursaphelenchus xylophilus. Given that B. xylophilus evolved into a destructive pathogen after its introduction into Asia, B. mucronatus may also pose a potential threat to North American coniferous forests. Therefore, we assessed the potential global distributions areas of M. sutor and their relative dynamics under different climate scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5) in the current (i. considering only bioclimatic factors; ii. including anthropogenic factors) and in the future (2050s and 2070s) using an optimized Maximum Entropy ecological niche model. The mean area under the curve value of the optimized model was greater than 0.86 and the true skill statistic value was greater than 0.79. Potentially suitable habitat for M. sutor is driven by a combination of temperature (Bio1 and Bio2), precipitation (Bio14, Bio15, and Bio18), and human activities. In the current period, suitable areas are concentrated in Europe, East Asia, and North America, and are smaller in the presence of anthropogenic disturbance than in the presence of bioclimatic factors alone. At the same time, under future climate scenarios, the potential range of M. sutor will always expand more than contract, with a projected increase of 1,329.02 to 1,798.23 × 104 km2 compared to the current time period, especially spread toward Canada and the United States of America in North America.

(Lepidoptera: Plutellidae), has become one of the most serious pests of cruciferous vegetables worldwide. Disrupting with courtship and mating behaviors has emerged as an important strategy for insect management. The fruitless (fru) gene encodes a transcription factor that contains a BTB (Broad-Complex, Tramtrack and Bric a brac) and a zinc finger pair related to the C2H2 class. It plays a crucial role in regulating insect courtship behavior. In this study, the fru gene of P. xylostella (Pxfru) was cloned, revealing 7 alternative splicing forms (Pxfru-1 to Pxfru-7). Pxfru-1 to Pxfru-3 were non-sex-specific transcripts, while the remaining forms were male-specific. Subcellular localization experiments demonstrated that the transcripts encoding proteins containing BTB and zinc finger domains (Pxfru-1 to Pxfru-3) localized to the cell nucleus, whereas Pxfru-4 and Pxfru-5, which contain only one BTB domain, were localized in the nucleus and cytoplasm, respectively. Knockdown the expression of fru in male moths delayed occurrence of mating and reduced their preference to female sex pheromones. Meanwhile, suppression of fru expression in female P. xylostella decreased their attractiveness to males. The results of GC-MS and Y-tube olfaction experiments indicated that this change may be attributed to alterations in the proportion of sex pheromones. This study represents the first report of the fru gene influencing pheromone ratios in female insects, and provides a new perspective for understanding the function of fru in the courtship behavior of non-model insects.</p>","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144063664","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}

In the no-spray subplots of the natural infestation experiment, cotton fleahopper feeding increased square abscission, leading to yield loss and delayed boll maturity, especially in cultivars classified as late-maturing. Early maturing cultivars consistently showed faster boll opening regardless of cotton fleahopper. Artificial infestation experiments further confirmed increased square abscission, reduced boll numbers, and lower lint weights when infested with cotton fleahopper.

While immature stages of insects (nymphs, larvae) are often most damaging, they can be difficult to sample, and management decisions targeting immatures must be based on adult sampling. For some insect pests, such as the grape mealybug (Pseudococcus maritimus), pheromone trap observations of adults occur too late to warn growers about pest risk, since overwintering first-instar nymphs are the dominant stage that transmits grape leafroll-associated viruses. Here, we propose a method to determine the time when insecticide applications will be most effective to control first-instar grape mealybug nymphs, based on the alignment between a modeled progression of life stages across degree days and pheromone trap capture data. We used literature to build a grape mealybug phenology simulation model and a 6-yr dataset of grape mealybug males captured in pheromone traps to infer the time when most virus-transmitting nymphs have hatched and are susceptible to insecticides. Our results show it is unlikely that most overwintering first-instar grape mealybugs occur in early spring, and that insecticides aimed at preventing grape leafroll-associated viruses transmission should occur by late autumn.

Like many agronomic crops, hemp production faces several insect pest challenges. Aphids pose a unique threat to hemp, being found in both indoor and outdoor production. Aphids affect hemp by reducing plant growth, bud production, concentrations of cannabinoids, and removing photosynthate. Additionally, aphids are vectors of plant viruses, and several species are known to transmit viruses to hemp. Limited research exists regarding the host suitability of hemp for common aphid pests in Louisiana. Thus, experiments were conducted to determine the life table statistics and feeding behaviors of Myzus persicae, Aphis gossypii, and Phorodon cannabis to determine the potential pest population dynamics of these pests on hemp. Hemp cv. Maverick was not a good host for either A. gossypii or M. persicae, resulting in negative intrinsic rates of increase and no sustained colonization. Although individuals of M. persicae and P. cannabis initiated probes at comparable rates, M. persicae probe durations were significantly shorter and probes were more frequent, indicating an absence of positive responses to probing hemp. A significant difference was observed in the percentage of individuals of A. gossypii initiating probes, and probe duration was significantly shorter than P. cannabis and significantly longer than M. persicae. Both A. gossypii and M. persicae spent significantly less time probing in phloem when compared with P. cannabis.
