While its general biology has been well studied, the phenomenon of pupal ring formation remains poorly understood. This study examined the factors influencing pupal ring formation under controlled laboratory conditions. Results showed that pupal rings were formed exclusively when larvae were reared on an artificial diet, with no ring formation observed on corn-stalks. Females exhibited a significantly higher tendency to participate in ring formation than males. Additionally, male participation increased proportionally with the number of rings formed, a pattern not observed in females. The size of the rearing arena significantly influenced ring formation, with smaller arenas (6 cm diameter) promoting more frequent pairing, particularly among females. Temperature also played a significant role: lower participation rates were recorded at 22 °C compared to 25 °C and 28 °C, although the number of rings formed did not differ significantly across temperatures. Developmental stage and sex composition further influenced pairing behaviour; pupal rings formed only among individuals of similar maturity, and male participation was significantly reduced in all-male groups compared to mixed-sex groups. These findings suggest that pupal ring formation in O. furnacalis is modulated by dietary substrate, larval sex, environmental conditions, and developmental synchrony, offering new insights into the behavioural ecology of this pest.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-7"},"PeriodicalIF":1.6,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144324561","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}

Recently, the presence of mealybugs and pineapple mealybug wilt-associated viruses (PMWaV)-1, -2, and -3 has been reported in the provinces of Satipo and Chanchamayo, in Peru's central jungle. This study aimed to molecularly identify mealybugs collected from the Hawaiiana cultivar and the MD-2 hybrid in those provinces to determine if they are indeed hosts of the PMWaV-1, -2, and -3. Through amplification and sequencing of the internal transcribed spacer ribosomal genes, the mealybugs were identified as Dysmicoccus brevipes. In the phylogenetic analysis of these D. brevipes, Peruvian isolates were associated with isolates from India, China, Taiwan, and Japan. In addition, our results confirmed the presence of PMWaV-1, -2, and -3 in all mealybug specimens collected from both the Hawaiiana cultivar and the MD-2 hybrid tested, with these PMWaVs showing a 99% sequence identity with others recently reported in Peru. Therefore, D. brevipes is a host and probable vector of PMWaV-1, -2, and -3 for the cultivar Hawaiiana and the hybrid pineapple MD-2 in Satipo and Chanchamayo, Peru. Based on these findings and observations of crop management strategies in these provinces, we recommend integrated management practices to control this pest.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-8"},"PeriodicalIF":1.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315922","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}

This study evaluated the effects of storage temperatures of 9°C and 12°C, along with incubation periods of 7, 14, 21, 28, and 35 days, on the biological fitness of Bracon adoxophyesi Minamikawa (Hymenoptera: Braconidae). The results demonstrated that the survival rates of adult wasps exceeded 90.0% after being stored at both 9°C and 12°C for 35 days. At these temperatures, female wasps exhibited their longest lifespan at 14 days, whereas male longevity decreased progressively from 7 to 35 days. The parasitism rates observed were 43.0% at 9°C and 46.0% at 12°C after 7 days of refrigeration, with a subsequent reduction noted after 35 days. The fecundity of parasitic wasps decreased with the extension of storage time, but no significant difference was found in total egg production within 28 days of storage. Additionally, cold storage did not significantly affect the survival of the offspring; however, the proportion of females among the raised offspring was higher than in the control group. In comparing fitness parameters to the control, wasp vitality was notably higher after 21 days of storage at 9°C or 14 days at 12°C, indicating that these combinations of temperature and time are optimal.

E. Smith) (Lepidoptera: Noctuidae), is a highly destructive polyvorous pest with a wide host range and the ability to feed continuously with seasonal changes. This destructive pest significantly damages crops and can also utilize non-agricultural plants, such as weeds, as alternative hosts. However, the adaptation mechanisms of S. frugiperda when switching between crop and non-crop hosts remain poorly understood, posing challenges for effective monitoring and integrated pest management strategies. Therefore, this study aims to elucidate the adaptability of S. frugiperda to different host plants. Results showed that corn (Zea mays L.) was more suitable for the growth and development of S. frugiperda than wheat (Triticum aestivum L.) and goosegrass (Eleusine indica). Transcriptome analysis identified 699 genes differentially expressed when fed on corn, wheat, and goosegrass. The analysis indicated that the detoxification metabolic pathway may be related to host adaptability. We identified only one SfGSTs2 gene within the GST family and investigated its functional role across different developmental stages and tissues by analysing its spatial and temporal expression patterns. The SfGSTs2 gene expression in the midgut of larvae significantly decreased following RNA interference. Further, the dsRNA-fed larvae exhibited a decreased detoxification ability, higher mortality, and reduced larval weight. The findings highlight the crucial role of SfGSTs2 in host plant adaptation. Evaluating the feeding preferences of S. frugiperda is significant for controlling important agricultural pests.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-12"},"PeriodicalIF":1.6,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144282387","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}

Predation trials across different prey densities were performed with these adult coccinellid predators. Logistic regression analysis confirmed a Type II functional response for all the three species used in the experiments. Among the three, S. posticalis showed a superior predatory efficiency, with the highest attack rate (a) (0.0994 h-1), shortest handling time (Th) (0.5016 h) and a maximum theoretical predation rate (K) of 48.76 aphids. P. saundersi and P. horni showed lower predatory parameters, positioning S. posticalis as the most efficient predator. These findings underscore S. posticalis as a promising candidate for biological control of M. persicae, with a clear advantage in predation metrics over P. saundersi (a = 0.0876 h-1; Th = 0.5193 h; K = 48.27 aphids) and P. horni (a = 0.0695 h-1; Th = 0.5316 h; K = 47.97 aphids).

Survival rates of A. gossypii varied significantly across C. annuum varieties. Notably, Hap3 and Hap17 thrived on 'LZ' but failed to establish populations on 'LA'. The net reproductive rate (R0), average generation time (T), and intrinsic rate of increase (rm) differed markedly between Hap3 and Hap17 across C. annuum varieties. Feeding on 'LZ' resulted in a significantly higher R0 value (26.49) for Hap3 relative to other varieties. The T (7.60 days) and rm (0.27) values for Hap3 on 'SE' were superior to those observed on other C. annuum varieties. These findings indicate that 'SE' is the optimal host for Hap3 growth, while 'LZ' best supports Hap17. Both haplotypes exhibited the lowest adaptability to 'LA'. Therefore, the utilisation capacity of A. gossypii populations on C. annuum demonstrates differentiation, and the resistance levels among C. annuum varieties to A. gossypii vary.
