This study introduces the Pole-dance bioassay, a novel no-choice method optimized for high-throughput screening of time-dependent repellency, demonstrated through tests on twenty botanical volatiles against T. urticae. Four statistical models, probit, two-parameter Hill, four-parameter Hill, and Gaussian Process (GP) regression, were compared for analyzing time-response landing data, employing both experimental results and scenario-based synthetic datasets reflecting diverse curve shapes. GP regression often provided superior model fits, especially for biphasic or incomplete landing trajectories. While repellency rankings based on median effective time (ET50) and area under the curve (AUC) were highly correlated within respective models, the choice of model significantly influenced parameter estimates. AUC proved essential for quantifying activity for highly potent compounds where ET50 was inestimable (e.g., t-cinnamaldehyde, 1,8-cineole, (-)-terpinen-4-ol, thymol) and offered complementary insights into repellent effects. The Pole-dance bioassay combined with GP modeling establishes an optimized framework for statistically rigorous in vivo high-throughput screening against T. urticae.","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"95 3","pages":"34"},"PeriodicalIF":1.7,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12370553/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144948024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we hypothesized that the presence of T. urticae detrimentally affect the population growth of T. ludeni on the host plant. The experimental design involved analyzing a multifaceted ecological dynamic related to four biological attributes: oviposition, olfactory cues, web effects, and mite interaction. Data were analyzed using Generalized Linear Mixed Model (GLMM). Our results showed that T. urticae does not significantly influence the oviposition rate of T. ludeni. However, T. ludeni prefers its conspecifics over heterospecifics, avoiding the presence of the web produced by T. urticae. Additionally, our findings indicate that T. ludeni has a low population growth in plants with T. urticae, whereas T. urticae is favored by the presence of T. ludeni. Since both spider mite species may damage crop production by piercing plant cells with their mouthparts, our results suggest that their interaction may have broader implications for herbivorous mite ecology in agroecosystems, particularly because the population of T. urticae seems to be favored by interacting with T. ludeni. Therefore, these findings are significant for pest control strategies, as the presence of both spider mite species in the same agricultural ecosystem may result in one outnumbering the other instead of self-regulating each other.","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"95 3","pages":"32"},"PeriodicalIF":1.7,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144948037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study we assessed the variation of morphometric traits in unfed deutonymphs of Allothrombium fuliginosum which developed from larvae that had parasitized four different aphid hosts: Acyrthosiphon pisum, Aphis sambuci, Macrosiphum rosae and Hyadaphis sp. Analysis of 48 morphometric traits in 80 deutonymphs revealed significant differences between host groups in 19 traits, with M. rosae contributing the most to observed variability. Principal component analysis showed some distinct clustering of deutonymphs according to the host species parasitized by larvae. The smaller, with respect to basic body measurements, deutonymphs developed from larvae that parasitized M. rosae, despite the overall larger body size of this host. Thus, factors other than host size influence the morphology of mites.

The primary method currently employed to control tick infestations is the use of chemical acaricides. However, improper use leads to environmental contamination, residue in meat and milk, and the development of acaricide-resistant ticks. Therefore, alternative tick control methods that are safe for humans, animals, and the environment and that do not induce resistance are urgently needed. Diatomaceous earth (DE), a naturally occurring physical insecticide, has been proven to effectively kill various arthropods without producing resistance or toxic side effects. In the present study, the acaricidal effects of DE on larval, nymphal, and adult stages of Haemaphysalis longicornis ticks were evaluated using sprinkling and immersion methods. In larvae, mortality was first observed 20 min after sprinkling, with a 100% mortality rate by 200 min. Immersion treatment of nymphs with DE resulted in initial mortality observed after 120 min, and the mortality rate reached 100% after 12 h. The initial mortality rate for adult male ticks was 5% after 8 h of treatment, and 5% for adult female ticks after 6 h treatment. By 24 h, the mortality rates for both adult male and female ticks had reached 100%. These findings demonstrate that DE has acaricidal effects on the larval, nymphal, and adult stages of H. longicornis under laboratory conditions. Our study provides a foundation for future field trials to explore DE as a safe and effective alternative to chemical acaricides in tick control methods.","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"95 3","pages":"30"},"PeriodicalIF":1.7,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144872160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the present study aimed to determine the composition of the acarofauna in the leaf axils of two Araceae species, Xanthosoma daguense Engl. and Xanthosoma sagittifolium (L.) Schott, as well as establish the aquatic and subaquatic aroid-mite network. For this, we collected mites from the phytotelmata of both species at two sites in the Colombian Central Mountain range. We found 16 morphospecies of mites belonging to the Gamasina, Uropodina, Sejida, Astigmatina, and other Oribatida groups associated with the phytotelmata of aroids. The most common genera identified were Histiostoma sp. and Hormosianoetus sp. (Histiostomatidae, Astigmatina). We reported for the first time the occurrence of Blattisocius dentriticus (Blattisociidae), Cheiroseius mesae (Blattisociidae), Galumna sp., Lucoppia sp., Malaconothrus sp., Oribotritia sp., and Uropodella sp. in phytotelmata, as well as B. dentriticus, Asca sp., Hormosianoetus sp., Lucoppia sp., Malaconothrus sp., and Phthicarus sp. in Colombia. The network exhibited high specialization and modularity; we identified three aroid-mite groups related to the Araceae species by sites. These results suggested that variations in the environmental conditions in the leaf axil and site scales affect the mite community.

In this study, we focused on a population of Eotetranychus asiaticus (Acari: Tetranychidae) colonising the galls formed by psyllid larvae (Trioza cinnamomi, Hemiptera: Triozidae) on the leaves of Cinnamomum yabunikkei (Lauraceae). We tested the hypothesis that inhabiting galls benefits E. asiaticus by reducing egg predation. In the field, almost all E. asiaticus individuals were found inside galls (96.7%). This spider mite inhabited 3.4% of the observed galls and reproduced within them, whereas leaves without galls hosted few mites. Predatory mites and Feltiella larvae used galls near those occupied by spider mites, indicating high predation pressure on the leaf surface. Laboratory experiments revealed that the proportion of eggs predated by Neoseiulus womersleyi (Phytoseiidae) females was lower on leaves with galls than on leaves without, suggesting that gall use provides an antipredatory advantage.

In this study, we examined the prey consumption and prey preference of Amblyseius andersoni (Chant) on two important agricultural pests, the two-spotted spider mite (Tetranychus urticae Koch) and the western flower thrips (Frankliniella occidentalis Pergande), at five different temperatures (15, 20, 25, 30, and 35 °C).

The prey consumption of T. urticae was the lowest at 35 °C (5.93 per day) and the highest at 25 °C (9.23 per day); the highest and the lowest prey consumption of F. occidentalis were observed at 30 °C (1.73 per day) and 15 °C (0.33 per day), respectively.

Reproductive diapause attributes also varied: reproductive diapause was induced under short-day conditions in S. sabelisi, whereas the other two species lacked such diapause. Moreover, phenotypic variation in the number of days required for egg hatching was highest in S. miscanthi ML form, suggesting retained ancestral variability that may have facilitated subsequent divergence.
