However, securing suitable food remains a persistent issue for the mass rearing of this beneficial insect. To understand how different feeding strategies impact reproductive success, we evaluated their effects on critical life table parameters and ovary development using a range of feeding options: natural prey Spodoptera litura Fabricius (Lepidoptera: Noctuidae) and Spodoptera exigua Hubner, alternative prey Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae), and an advanced artificial diet. E. furcellata fed on S. litura had the highest fecundity (326.96 eggs) and net reproduction rate (86.04 offspring). Moreover, those fed T. molitor exhibited the highest survival rate during the nymph stage (61.86%). Among all tested treatments, ovarian tube length reached its peak on the 14th day following the emergence of the adult. The group fed S. litura had the longest average length (4.021 mm), followed by those fed S. exigua (3.986 mm) and T. molitor (3.904 mm). Notably, E. furcellata fed on S. exigua displayed the highest number of fully developed follicles between days 3 and 21 after emergence. This research underscores the efficacy of utilizing natural prey, especially S. litura, and alternative prey, T. molitor, for enhancing the reproductive success and survival of E. furcellata, providing critical insights for optimizing mass-rearing techniques and informing integrated pest management strategies that leverage this beneficial insect for effective biological control across diverse agricultural systems.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660169","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 aims of the current study were to (i) evaluate the efficacy of the commonly used LLINs (deltamethrin, alpha-cypermethrin, and etofenprox) for direct lethality, (ii) assess the baseline mobility after exposure, and (iii) to evaluate the sublethal effects among LLINs against Rhyzopertha dominica and Tribolium castaneum. To accomplish this, we exposed cohorts of both species to 0.4% (w/w) deltamethrin, 0.34% alpha-cypermethrin, or 8% etofenprox for periods of 5, 60, or 120 min in the laboratory, and checked individuals for the condition after a duration of 0, 24, 72, or 168 h. The movement of alive and affected adults was assessed using Ethovision software over 60-min trials after a 5- or 60-min exposure to LLIN immediately or 72 h after exposure. After exposure for 60-min to deltamethrin and alpha-cypermethrin LLIN, mortality for both species was 86% to 98% higher when compared to the controls without insecticide. Etofenprox performed worse than the other active ingredients (AIs). In the baseline mobility assay, R. dominica netting exhibited a thigmotactic effect on movement, but not for T. castaneum. For both species, the movement was reduced by 77% to 99% deltamethrin netting above and beyond the thigmotactic effects. There was a sublethal reduction in movement after a 60-min exposure to both LLINs by 95% to 98% compared to control netting without insecticide. Overall, this study helps delineate the relationship in efficacy between these AIs for 2 cosmopolitan, destructive stored product insects.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660179","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}

Encarsia formosa (Gahan) (Hymenoptera: Aphelinidae) is one of the most extensively utilized biological control agents for the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). In the present study, we evaluated the effects of short-term heat stress on the functional response and host control efficacy of En. formosa, as well as the interspecific interactions between this parasitoid and the co-occurring parasitoid Eretmocerus hayati (Zolnerowich and Rose) (Hymenoptera: Aphelinidae). At all experimental temperatures, type II functional responses of En. formosa were observed in both parasitism and host feeding. The type of functional response remained unaffected by experimental temperature. Roger's model was utilized to fit the data. Based on the 95% confidence interval, pairwise comparisons of searching rate (a) and handling time (Th) across temperature regimes yielded no significant differences. In most instances, the increased temperatures did not affect the host control efficacy of En. formosa. The coexistence of En. formosa and Er. hayati exhibited a negative impact on En. formosa's parasitism but a positive effect on that of Er. hayati across all temperature regimes. These findings provide valuable knowledge regarding the functional dynamics of En. formosa under climate warming and underscore the importance of understanding interspecific relationships among biocontrol agents to effectively optimize pest management strategies.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660183","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}

This program, lasting from 1998 to 2012, was able to decrease the overall population of Formosan subterranean termites in the area but did not eliminate all detectable colonies. Since Operation Full Stop ended in 2012, there has been a significant decrease in the number of alates observed in the French Quarter during reproductive flight season. Pedigree analysis was conducted on alates trapped during major swarm events in 2021. It was determined that an average of 7.25 (SD = 2.95) distinct colonies per glue trap were contributing to these swarm events. A bait-use survey was also conducted in the French Quarter, in which all accessible properties were checked to determine whether termite bait products were still in use within the French Quarter. We determined that approximately half (51.00%) of the structures in the French Quarter still currently have bait products installed around their perimeter. The interception of durable baits by neighboring termite colonies may be the reason why there has not been an increase in alate numbers since Operation Full Stop ended.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634783","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}

Recent efforts have focused on overcoming such problem by accelerating the baiting process. To accelerate termite colony elimination, 20-hydroxyecdysone was proposed as a potential active ingredient due to its similar mode of action observed in chitin synthesis inhibitors. Termites ingesting 20-hydroxyecdysone displayed hyperecdysonism, and mortality occurred much faster than with chitin synthesis inhibitor-ingesting termites. However, trial with 20-hydroxyecdysone alone and 20-hydroxyecdysone mixed with noviflumuron baits with intact colonies of Coptotermes formosanus Shiraki failed to accelerate the colony elimination time due to the feeding cessation. To bypass this issue, lower concentrations of 20-hydroxyecdysone may be necessary and sequential feeding of chitin synthesis inhibitors and 20-hydroxyecdysone have been proposed. In this review, a few more potential approaches were summarized which can be used to accelerate termite baiting program.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635024","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}

Early season infestations can reduce plant stands up to 75% if untreated. Effective management of D. antiqua has historically relied on insecticide seed treatments, with spinosad being among the most commonly used options. However, declining control efficacy observed on a New York onion farm over several years raised concerns about the potential development of insecticide resistance. The purpose of this research was to (i) evaluate the efficacy of spinosad seed treatment in managing D. antiqua in the affected field from 2021 to 2024 and (ii) to assess the population's susceptibility to spinosad using a laboratory bioassay. Results from field trials revealed that the percentage of control of D. antiqua using spinosad seed treatment relative to a noninsecticide treatment declined from 51% in 2021 to -83% in 2024. Laboratory bioassay results showed an increase in LC50 values from insects collected from nontreated and spinosad-treated plants in 2023. These results document the first case of reduction in spinosad seed treatment efficacy in D. antiqua that has practical consequences for pest control (practical resistance). Given the critical role of spinosad seed treatment in onion maggot management, these results underscore the need for evaluating resistance prevalence in other populations across North America.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627122","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}

Pupa of the silkworm (Bombyx mori L.), a byproduct of the sericulture industry is a cheap and sustainable alternative to fish meal. This study aimed to examine the impact of replacing fish meal with silkworm pupae meal on the growth performance and health profile of Gift Tilapia fingerlings (Oreochromis niloticus). Gift Tilapia fingerlings (3.38 ± 0.23 g) were divided into 4 groups (n = 60 in each group). These fish were reared for 10 wk and fed at the rate of 4% body weight daily at 10 am and 3 pm. The basal standard diet was given to the control. The other 3 experimental diets were prepared with 10% (SWP10), 20% (SWP20) and 40% (SWP40) replacement of fish meal with silkworm pupae meal. The results showed that the values of weight gain, feed efficiency ratio and organosomatic indices were significantly higher (P < 0.05) in the SWP40 group as compared to all other groups. The values of red blood cells, white blood cells, hematocrit, mean corpuscular volume, and hemoglobin concentration were also significantly improved in the SWP40 group. Whole-body crude protein differed non-significantly (P > 0.05) in all the study groups. The fat content was significantly higher in the SWP20 group. It can be concluded that silkworm pupae are a suitable source of protein to be substituted in the feeds of Gift Tilapia replacing 10% to 40% of fish meal for enhanced health profile and promising growth.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627111","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 this study, we compared the efficacy of a low-energy X-ray irradiator and a traditional gamma irradiator for achieving male sterility in both male pupae and adults of the mosquito Ae. aegypti Linn. We found that both irradiators performed equivalently with 99% sterility achieved at ~50 Gy when male pupae were irradiated and ~70 Gy when male adults were irradiated. There were no differences in lifespan or male mating competitiveness at the sterilizing dose between the 2 irradiation platforms.

In 2019 and 2020, shothole leafminers caused high levels of damage to oak trees in several states in the mid-Atlantic region. The objectives of this study were to compare oak shothole leafminer damage on the genus Quercus L. (Fagales: Fagaceae) including northern red oak (Quercus rubra L), chestnut oak (Q. montana Willd.), white oak (Q. alba L), scarlet oaks (Quercus coccinea Münchh.), and to fill critical knowledge gaps of oak shothole leafminer biology. Leaf area reduction, percent damaged leaves, foliage transparency, and crown dieback were calculated to compare damage experienced by the different oak species. Emergence and Malaise traps were used to assess adult population sizes. Chestnut oak was consistently the oak species with the least leaf area reduction and foliage transparency. The injuries on chestnut oak leaves were primarily small and uniform holes (\"shotholes\") due to this leafminer. In contrast, northern red oak and scarlet oaks showed high susceptibility. Damaged leaves of these species frequently were deformed or incomplete, and the shotholes varied in size, resulting in greater leaf area reduction. Experiments showed that the conspicuous shothole damage caused by this leafminer is related to puncturing by the female flies into leaves of young buds. In conclusion, oak shothole leafminer is a native cryptic pest and outbreaks are visually apparent only when emergence coincides with oak bud and early leaf development.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627071","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}
