Biological control using predatory mites offers a potentially sustainable alternative to chemical management, yet the effectiveness of different mite species and the role of prey developmental stage remain poorly understood. In this study we compared the predation capacity of four phytoseiid mites-Amblydromalus limonicus, Amblyseius herbicolus, Amblyseius lentiginosus, and Neoseiulus cucumeris-on first- and second-instar larvae of H. haemorrhoidalis under controlled laboratory conditions. No-choice experiments revealed significant differences (p < 0.001) among predator species and thrips stages, with A. limonicus exhibiting the highest predation rates and a strong bias towards first-instar thrips, while the other mite species showed negligible thrips consumption. Choice experiments further demonstrated that A. limonicus exclusively preyed on first-instar thrips when both larvae instars were simultaneously available, confirmed by Manly's preference index (Manly's α = 1). Functional response analysis indicated a Type II functional response of A. limonicus feeding on first-instar thrips, characterised by a high attack rate at low prey densities and saturation at higher densities due to handling time constraints. These preliminary 24 h laboratory results indicate pronounced stage-specific predation under the conditions tested and show that A. limonicus performed better than the other predatory mite species examined. However, because the experiments included no predator-free controls, the findings should be interpreted cautiously and future studies under field or orchard conditions are needed to demonstrate the effectiveness of A. limonicus in H. haemorrhoidalis biocontrol.</p>","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"96 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13152977/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147835636","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}

This study investigates the potential of Mentha suaveolens and Phlomis fruticosa, to act as reservoir plants for the predatory mite Typhlodromus (Anthoseius) recki in tomato crops. Two experiments were conducted in controlled conditions: the first to assess the suitability of these plants for four tomato pests (Tuta absoluta, Trialeurodes vaporariorum, Tetranychus urticae, and T. turkestani) and a second to evaluate the influence of the reservoir plant species, the presence of tetranychid mites on them, and infestation by Aculops lycopersici of nearby tomato plants on predator and tetranychid mites development and dispersal. In experiment 1, neither of the two reservoir plants was favorable to T. absoluta and T. vaporariorum. Mentha suaveolens was favorable to both Tetranychus species, while P. fruticosa was favorable to T. turkestani but much less T. urticae. In the experiment 2, Typhlodromus (A.) recki reproduced and developed on both reservoir plants, even without prey, with higher densities on M. suaveolens. Predators dispersed to tomato plants in all treatments, with consistently higher densities found on tomato plants infested by A. lycopersici. A higher dispersal seems also to better occur when M. suaveolens is the reservoir plant vs. P. fruticosa. The numbers of tetranychid mites remained very low on both reservoir plants and adjacent tomato plants, likely due to efficient predation. These results indicate that both plants can act as reservoirs for T. (A.) recki, even in the absence of prey, but that M suaveolens would be more favorable to adjacent tomato colonization.

Plant-derived essential oils have therefore attracted attention as alternative control agents. In this study, the field efficacy of nanoemulsions (NEms) prepared from peppermint (Mentha piperita; P-NEms), thyme (Thymus vulgaris; T-NEms), and eucalyptus (Eucalyptus globulus; E-NEms) oils against Varroa mites was evaluated at three doses (50, 100, and 200 ppm), and compared with a positive control (amitraz) and a negative control (no treatment). All tested nanoemulsion formulations significantly reduced Varroa mite density, with the highest efficacy (percentage reduction relative to initial mite counts) observed at the 200 ppm dose. The T-NEms200 treatment exhibited the strongest acaricidal activity (75.3%). Peppermint and eucalyptus NEms also achieved high efficacy. The positive control, amitraz, showed 53.5% efficacy and was less effective than the higher NEms doses, while mite loads increased in untreated colonies. The nanoscale droplet structure of the formulations may have contributed to enhanced contact between active compounds and mites. Overall, these findings demonstrate that essential oil-based nanoemulsions reduced Varroa mite populations in a concentration-dependent manner at the colony level.

Monitor lizards are known to harbor several tick species that serve as vectors for a variety of pathogens. No prior information is available in the literature regarding ticks infesting V. bengalensis in Pakistan as well as regarding the occurrence of Toxoplasma gondii in these ticks. Therefore, we aimed to determine the molecular prevalence of T. gondii in Amblyomma gervaisi ticks (n = 93) collected from 24 V. bengalensis in Buner District, Khyber Pakhtunkhwa Province, Pakistan, between May and September 2023. Polymerase chain reaction (PCR) amplified a 300 bp fragment specific for the ITS-1 region of T. gondii in 10 of the 93 (11%) A. gervaisi ticks. DNA sequencing and BLAST analysis confirmed the presence of T. gondii. Phylogenetic analysis showed that these sequences clustered with the ITS-1 sequences of T. gondii detected in reptiles and mammals from Pakistan, Brazil, China, Tunisia and Portugal. The prevalence of T. gondii in A. gervaisi was not limited to a specific tick sex, feeding stage or month of sampling. However, among the tick developmental stages, nymphs had the highest rate of T. gondii infection. In conclusion, for the very first time from Pakistan, we are reporting the presence of T. gondii in A. gervaisi that were infesting monitor lizards. We recommend that similar and large scale studies should be conducted in all those areas of Pakistan that are unexplored for the presence of T. gondii in A. gervaisi ticks. Prevalence of this parasite should also be screened in all the animals harboring these as well as other tick species.

Specifically, we evaluated (1) the efficacy of spore suspensions from five isolates of four Trichoderma species (Trichoderma afroharzianum, T. guizhouense, T. harzianum and T. virens) and their combinations on different biological stages of T. urticae, (2) the efficacy of T. afroharzianum spore suspension on different populations of T. urticae (green and red forms) and T. turkestani in both Petri dish and pot experiments.

A total of 6,947 mites were collected belonging to three families (Laelapidae, Macronyssidae and Trombiculidae) on 478 hosts. Individually selected mite samples (N = 186) were subjected to DNA extraction and further tested for occurrence of Rickettsia, however, no sample retrieved positive results. This study reports new mite records for hosts and localities and explores the dynamics of the ecology of mites and their hosts in a particular area inside the Atlantic Rainforest.</p>","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"96 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13091874/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147716499","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}
