This study evaluated the feeding preference, nutritional indices, and oviposition performance of olive weevil adults feeding on five Oleaceae plants, F. pennsylvanica, O. europaea, Osmanthus fragrans Lour., Syringa oblata Lindl., and Ligustrum × vicaryi Rehder. The results showed that adult olive weevils preferred to feed on O. fragrans, with a selection rate of 56.25 ± 6.91%, followed by F. pennsylvanica and O. europaea. No feeding preference was observed on L. × vicaryi. The nutritional index F values for female adult weevils feeding on F. pennsylvanica and S. oblata were the highest, 0.37 ± 0.02 g and 0.37 ± 0.01 g, respectively. For both female and male adults, F values were lowest on O. europaea for both sexes, while ECD, ECI, and GR were highest on this host. Although adult olive weevils preferred O. fragrans, the female adults did not exhibit oviposition behaviour after feeding on O. fragrans. After feeding on F. pennsylvanica and S. oblata, the maximum number of eggs laid by female adults was 19.20 ± 3.90 and 18.80 ± 3.11, respectively. Therefore, we believe that F. pennsylvanica and S. oblata may be the plants with the most serious harm caused by adult olive weevils, while O. fragrans could be used as a trap plant to attract female adult olive weevils.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-7"},"PeriodicalIF":1.7,"publicationDate":"2026-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148270664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The timing of crop sowing could impact arthropod communities by altering basal resource availability and quality, manifesting in altered nutrient availability for herbivorous arthropods and cascading impacts on natural enemy fitness and function. This study investigates how the timing of crop sowing impacts arthropod predator nutrition and whether associated differences relate to changes in prey availability. Arthropod predators and their prey were collected from adjacent plots of winter- and spring-sown wheat. The biochemical macronutrient (carbohydrate, lipid and protein) content of predators was determined by colourimetric assays and compared between winter- and spring-sown crops using multivariate models. Predator nutrient contents were compared to prey availability inferred using null network models based on both recent and current prey abundances. The nutrient contents of arthropod predators differed significantly between winter- and spring-sown wheat, driven by differences in carbohydrate content, and prey abundances similarly differed, but neither recent nor current prey availability explained differences in predator nutrition. These findings may indicate that prey quality, rather than identity, changes with the developmental stages of crops sown at different times. The different nutritional states of predators in crops sown at different times may have important implications for the spillover of natural enemies of crop pests between crops.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-8"},"PeriodicalIF":1.6,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148249386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Age-stage, two-sex life tables of B. helichrysi reared on six plum cultivars under controlled laboratory conditions were constructed. The total phenolic content in the leaves of each cultivar was quantified. Compared with the Red Beaut cultivar of plum, the fecundity, net reproductive rate, intrinsic rate of increase, finite rate of increase, and total longevity of B. helichrysi were significantly lower, and the mean generation time was significantly longer on the Fortune cultivar, followed by Angeleno, Friar, Black Amber, and Santa Rosa. The total phenolic compounds in the leaves of the different cultivars were as follows: Fortune > Angeleno > Friar > Black Amber > Santa Rosa and Red Beaut. The seasonal incidence of aphid was also studied under the field condition, which showed that the highest mean aphid population was recorded during March (113.17/10 leaves), followed by April (74.00/10 leaves), and declined in May (17.30/10 leaves). These findings suggest that the B. helichrysi resistance of cultivars, mainly Fortune and Angeleno, is influenced by the total phenolic compounds in their leaves. The negative correlation observed between phenolic compounds and aphid incidence suggested a potential role of phenolic compounds in mediating plant resistance to aphids. The findings will inform integrated pest management strategies for plum cultivation, promoting crop resilience and ensuring food security.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-9"},"PeriodicalIF":1.6,"publicationDate":"2026-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148210194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While deltamethrin is extensively utilised in mosquito vector control, localised or intermittent sublethal exposure to this insecticide may influence mosquito population dynamics. To investigate the role of environmental residual deltamethrin in inducing transgenerational fitness costs in Ae. albopictus, this study established three different concentrations of deltamethrin solution based on its half-lethal concentration (0.002275 mg/L) for long-term exposure. And four consecutive generations were reared under these conditions. We monitored macroscopic growth and developmental data, reproductive capacity, and expression levels of yolk protein genes (vitellogenin) in each generation. Results showed that sublethal multigenerational deltamethrin exposure significantly prolonged the developmental period of Ae. albopictus; however, it did not have a significant impact on pupation or eclosion rates. In terms of fecundity, exposure to deltamethrin reduced the relative expression levels of vitellogenin-A1 and vitellogenin-C in Ae. albopictus, which was correlated with reduced reproductive output. Furthermore, there was a reduction observed in both single female oviposition rates and egg hatching success among exposed individuals. These findings highlight sublethal responses that may impact population dynamics and reproductive success in the field, underscoring the importance of considering chronic, low-dose insecticide effects in integrated vector management strategies.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-10"},"PeriodicalIF":1.6,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148154904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives of this study were to determine the exposure time, density, and ideal larval instar of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) and to verify whether the parasitoid's previous experience affects its interaction with the host insect and the influence of these factors on the parasitism rate. In three bioassays, fly larvae were placed in 'parasitism units' to test different methods of exposure to female parasitoids. The variables included the previous experience of the female parasitoid with oviposition, the exposure time (30, 60, 120, 240, and 480 min) of the larvae to the parasitoid and the number (5, 10, 15, and 20) and instar (second and third) of the fly larvae. The flies and parasitoids that emerged were quantified, and the parasitism rate and sex ratio of the parasitoids were calculated.

Nevertheless, the current status of chlorantraniliprole resistance in P. absoluta has not been well examined in Türkiye. This study investigated chlorantraniliprole resistance and the associated mechanisms in field populations of P. absoluta. Toxicity assays revealed that P. absoluta developed moderate to high levels of resistance (13.8- to 97.7-fold) to chlorantraniliprole. Biochemical assays showed a significant correlation between cytochrome P450 monooxygenase activity and resistance (R2 = 0.677, P < 0.05). Although no significant association was found between ryanodine receptor (RyR) expression levels and resistance (R2 = 0.145, P < 0.05), several known target-site mutations (I4746M/K and G4903E/V) were identified. Lastly, the P. absoluta RyR (PaRyR) gene sequence was characterised, revealing a 15,633-bp open reading frame encoding 5,121 amino acid residues, with 78% sequence identity to RyR isoforms from other insects. PaRyR was predicted to embrace all the hallmarks of RyR, including a well-conserved C-terminal domain, six transmembrane domains, and a large N-terminal domain.

However, the influence of vegetable and fruit waste (VFW) substrates on insect performance, nutrient composition, frass quality, and economic efficiency remains poorly defined. This study evaluated five substrate levels obtained by mixing laying hen feed with VFW at 0%, 25%, 50%, 75%, and 100%, assessing their effects on the growth performance, body measurements, chemical composition, frass characteristics, and economic traits of BSF larvae and prepupae. The results showed that up to 75% VFW can be used to rear BSF up to 23 days of age without compromising growth traits. Substrate reduction ranged from 67.2% to 89.4%, and larval-to-prepupal conversion increased with feed intake. VFW level significantly affected larval and prepupal nutrient profiles, including dry matter, crude protein, ether extract, nitrogen-free extract, and chitin. Frass from the 100% VFW substrate exhibited the highest nutrient concentration, although this inclusion level impaired feed conversion due to elevated fibre content. Economic analysis indicated that using VFW can reduce substrate costs without negatively affecting revenue. Overall, a VFW inclusion level of up to 75% is recommended as the optimal balance between insect growth efficiency, nutrient recycling, and frass fertilising potential.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"355-370"},"PeriodicalIF":1.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146257671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The values of efficiency of conversion of digested food were lower on Baghmalek and Parto and higher on VC6368 and VC6371. The lowest value of larval gain weight was on Parto. The highest proteolytic and amylolytic activities of larvae were observed on Veys and India, respectively; while the lowest enzyme activities were recorded on Parto. Our findings indicate that the low protein content combined with high levels of anthocyanin, total phenolics, and flavonoids may contribute to the potential tolerance of mung bean varieties against H. armigera. Cluster analysis revealed that VC6368 and VC6371 were the most suitable varieties for H. armigera development, whereas Baghmalek and Parto were nutritionally less suitable and may severe as promising candidates for breeding or cultivation to minimise damage caused by this pest.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"325-333"},"PeriodicalIF":1.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146099845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
