Roxb. plants, and lessen its production. Successful oviposition by herbivorous insects on their host is an important factor in the host acceptance process. In this context, it is important to investigate whether leaf surface wax chemicals from three ridge gourd cultivars (Abhiskar, Debsundari and Jaipur Long) could serve as short-range attractants and stimulate oviposition in A. lewisii females. Surface waxes were isolated from each leaf using the gum arabic method. Twenty-one n-alkanes from n-C12 to n-C34 and nine free fatty acids (FFAs) from C12:0 to C19:0 were detected and quantified by GC-MS and GC-FID, respectively. One leaf equivalent surface wax (LESW) of each cultivar or a synthetic blend consisting of n-alkanes and FFAs mimicking one LESW of the same cultivar served as attractants through Y-tube olfactometer bioassays and stimulated oviposition in A. lewisii females. However, one LESW of Jaipur Long or a synthetic blend of n-alkanes and FFAs mimicking one LESW of Jaipur Long served as more potent oviposition stimuli in females than one LESW or synthetic blends mimicking one LESW of the other two cultivars. In field trials, a synthetic blend of pentadecane, heptadecane, pentacosane, hexacosane and linoleic acid mimicking Jaipur Long at mole ratios of 1:14.45:1.68:1.38:1.62 at 1.6 g/ml petroleum ether when used as lure in funnel traps resulted in attraction of A. lewisii. Hence, the above synthetic blend could be used as a lure in baited traps in eco-friendly pest management strategies.","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"51 3","pages":"57"},"PeriodicalIF":2.2,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144132434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined the feeding preferences, developmental duration, survival rates, and digestive efficiency of the mountain pine beetle across different life stages under different nutritional conditions. We tested three artificial diets with varying protein-to-carbohydrate ratios, including high-protein-low-carbohydrate (HP-LC), medium-protein-medium-carbohydrate (MP-MC), and low-protein-high-carbohydrate (LP-HC). The results showed stage-specific differences in feeding preference among beetle larvae. Early-instar larvae preferred HP-LC and MP-MC diets, whereas late-instar larvae preferred LP-HC diets. Adults of both sexes strongly favoured LP-HC diets. Larvae on MP-MC diets exhibited the fastest development and highest digestive efficiency, indicating optimal protein-carbohydrate balance for growth. Survival was highest on the HP-LC and MP-MC diets but was lower on the LP-HC diets, especially in early instars. Poor digestive efficiency in LP-HC diets suggests that excessive carbohydrates hinder nutrient assimilation. These findings show that mountain pine beetle developmental stages have distinct nutritional needs, with early instar larvae requiring higher protein for survival and development. The observed dietary shifts may be linked to seasonal changes in the nutrient composition of host trees and fungal symbionts of the mountain pine beetles. These stage-specific nutritional preferences further suggest opportunities to disrupt beetle growth through targeted, nutrition-based pest management strategies.","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"51 3","pages":"56"},"PeriodicalIF":2.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144110986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dispersal and host colonization dictate spread and establishment of MPB populations, but this comes with energetic, time, risk, and opportunity costs. As MPB exhibit continuous flight polyphenisms, researchers have proposed that energy use during flight may trigger responsiveness to the semiochemicals that orchestrate the colonization of host pine trees, but this effect has not been demonstrated empirically. Here, we test the hypothesis that flight exercise impacts subsequent behavioral response to semiochemicals in two olfactometer experiments that simulate 1) female beetle pioneer response to host volatiles and 2) male and female joining beetle response to host volatiles and the female-produced aggregation pheromone, trans-verbenol. We also assess antennal response of female beetles to α-pinene post-flight in an electroantennogram bioassay. Female MPB with low condition due to energy expenditure responded strongly to host semiochemicals post-flight. The antennal response of female MPB to the host volatile α-pinene increased with relative lipid content of beetles. Male behavioral response to semiochemicals was not influenced by body condition or exercise by flight. The effect of flight and body condition on orientation to semiochemical cues may influence individual dispersal patterns. These findings should be considered in the refinement of dispersal models that incorporate individual variability to predict spread of MPB in its expanded range.","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"51 3","pages":"54"},"PeriodicalIF":2.2,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144086268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pheromones offer a promising strategy for mitigating FAW damage through monitoring, mass trapping, and mating disruption. Understanding the pheromone composition of local FAW populations, as well as the variation in pheromone composition and production influenced by the mating status and age of FAW females, provides valuable insights into the factors contributing to pheromone production variability. This study investigated chemical composition of pheromone compounds of FAW population in Australia, temporal pattern of release, and the effect of mating status and age of FAW female on compounds release and production. Pheromone glands were collected by solvent extraction, whereas headspace volatiles were collected by solid phase microextraction (SPME) method. The sample contained four compounds (Z)-7-dodecenyl acetate (Z7C12Ac), (Z)-9-dodecenyl acetate (Z9C12Ac), (Z)-9-tetradecenyl acetate (Z9C14Ac) and (Z)-11-hexadecenyl acetate (Z11C16Ac), with Z9C14Ac present in a significantly higher amount. The maximum quantity of compounds from headspace volatiles was released between 4 to 6 h into the scotophase, while the compounds obtained from gland extraction varied across different phases of the scotophase. Younger FAW female released and produced higher amounts of compounds compared to the older individuals. Mated females have significantly higher compounds titre in their pheromone glands compared to the virgins, despite the latter releasing more volatile compounds.

They respond to biotic and abiotic stress, for instance, they can detect damage caused by insect feeding or oviposition and respond by releasing volatile compounds, known as herbivore- or oviposition-induced plant volatiles (HIPVs or OIPVs). The corn leafhopper, Dalbulus maidis (DeLong and Wolcott), is a sap-sucking insect that has been causing challenges to maize growers across the Americas by transmitting phytopathogens that cause substantial production losses. In this study, we evaluated whether maize plants modify their volatile emissions in response to different densities of pathogen-free D. maidis adults, the type of injury, and varying injury durations at two distinct vegetative stages. The results showed that injury caused by corn leafhoppers induced the release of HIPVs and OIPVs, with the response influenced by the plant stage, insect density, type of injury and injury duration. Density primarily affected the quantity of volatile induction, injury duration shaped the induced blend, and plant stage influenced all these aspects. Consistently induced compounds by all the factors tested included (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT), (E,E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene (TMTT), (E)-β-caryophyllene, and (E)-β-farnesene. Whereas the oviposition injury induced only two volatiles: nonanal and decanal. This study highlights how maize respond with different blend profile of HIPVs and OIPVs, demonstrating that maize adapts its volatile emissions depending on the intensity of stress it has been submitted. These findings can be further explored in multitrophic interactions, potentially influencing natural enemies that utilize these volatiles as cues in the environment.","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"51 3","pages":"53"},"PeriodicalIF":2.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144026492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies suggest that ants modify the cuticular hydrocarbons of mutualistic aphids they attend, but it is unclear which compounds are implicated in recognition. Thus, we investigated the chemical basis for the discrimination between attended and unattended aphids, Aphis gossypii Glover (Hemiptera: Aphididae), by the ant Tapinoma ibericum (Santschi, 1925) including cuticular hydrocarbons (CHCs and non-CHCs) compounds in the analysis. Chemical profiles of 14 colonies of A. gossypii attended by ants for three days were significantly different from those of unattended aphids. These results show that contact with T. ibericum rapidly induces modification of the cuticular profiles of the aphids on which they feed. Moreover, the compounds of unattended aphid A. gossypii also change over time but differ from those of attended aphids. The main compound of the ant cuticle (3,15-di-MeC27), which is highly abundant in attended aphids, was identified as a possible recognition marker, but without forgetting other identified compounds that may also play a predominant role in the ant-aphid mutualistic interactions.

While recent studies have investigated the influence of domestication on plant-derived food sources, its effect on guttation-a nutrient-rich exudate produced by many plants-remains unexplored. In this study, we examined the effects of guttation droplets from wild and cultivated highbush blueberries on the fitness (longevity and fecundity) and feeding preferences of three insect species from different trophic guilds: an herbivore (Drosophila suzukii), a parasitoid (Trichopria drosophilae), and a predator (Chrysoperla carnea). Additionally, we analyzed and compared the size and nutritional composition-specifically, total sugar and protein content-of guttation droplets between wild and cultivated blueberry plants. Our results indicated that guttation from wild plants enhanced the longevity of all three insect species, often surpassing that of cultivated plants and diets containing only sugar or sugar plus protein. In choice assays, all three insect species consistently preferred guttation from wild plants over that from cultivated ones. Although the guttation droplets from cultivated plants were larger, those from wild plants contained higher concentrations of sugars (six times more) and proteins (five times more), which likely contributed to the insects' enhanced fitness and preference for wild plant guttation. These findings indicate that domestication has reduced the ecological functionality of guttation in blueberries by potentially influencing tri-trophic interactions. Understanding how domestication affects plant-derived food sources like guttation could have important implications for the conservation of natural enemies in agricultural landscapes.","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"51 3","pages":"51"},"PeriodicalIF":2.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143993996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine whether woodrats currently feeding on creosote also retain the ability to consume and biotransform the PSMs in their ancestral diet of juniper, we compared various metrics of hepatic biotransformation in a population that ingests creosote bush (Mojave woodrats) to one that specializes on the ancestral diet of juniper (Great Basin woodrats). We investigated PSM biotransformation capabilities by quantifying the hepatic metabolism of α-pinene, a common terpene in juniper. We also measured total cytochrome P450 content, cytochrome P450 2B (CYP2B) and glutathione S-transferase (GST) concentrations, and the activity of GST in the livers of both populations consuming control (rabbit chow) and juniper diets. There were no differences in hepatic metabolism of α-pinene, total P450 content, or CYP2B concentration between woodrat populations when feeding on juniper. The only difference found was that the Mojave woodrats had higher GST activity compared to the Great Basin woodrats when feeding on juniper.
