The oil exhibited high acute toxicity to adult R. indica, with a median lethal concentration (LC₅₀) of 1.9 mg/mL. In addition to toxicity, the oil significantly reduced the mite population growth rate, survival, and egg hatchability. Interestingly, despite its lethal and sublethal effects, adult mites showed a marked preference for oil-treated areas in a laboratory two-choice bioassay, suggesting an attractant-mediated mechanism that may lead to mortality.

However, in integrated pest management (IPM) programs, understanding the influences of chemical pesticide applications on predatory mites is of great significance. In this study, the toxicity of ten pesticides on adult female N. agrestis was evaluated under laboratory conditions to determine their LC<sub>20</sub>, LC<sub>50</sub>, and LC<sub>90</sub> concentrations using the slide impregnation method. Among these pesticides, deltamethrin, which exhibited the highest toxicity, was selected for further investigation into its effects on the fitness of the next generation of N. agrestis preying on Tetranychus urticae Koch. The relative toxicity of the ten tested compounds, ranked from highest to lowest was as follows: deltamethrin, bifenthrin, endosulfan, methomyl, omethoate, imidacloprid, emamectin benzoate, carbosulfan, spinosad, and abamectin. Notably, deltamethrin exhibited the highest toxicity against N. agrestis, with a median lethal concentration (LC<sub>50</sub>) of 0.020 mg/L. Exposure to sublethal and LC<sub>50</sub> deltamethrin doses significantly impacted the adult lifespan and reproductive capacity of treated predators. Predators exposed to LC<sub>20</sub> concentrations exhibited markedly shorter offspring development time and lower fertility rates. The sublethal deltamethrin dose induced marked alterations in the life table parameters of N. agrestis. These findings suggested that deltamethrin adversely affected both the developmental duration and life table parameters of the next generation of N. agrestis.

Recently, Ips duplicatus (Sahlberg 1836) (Scolytinae), another species of bark beetle, that also affects Picea trees, has expanded its range westwards in Europe. In spruce stands, bark beetle populations are closely associated with various organisms such as fungi, nematodes, and mites. While phoretic mites and their relationship with I. typographus have been extensively studied in Europe, only single study has focused on the populations of phoretic mites associated with I. duplicatus. The aim of this study is to analyze and document the communities of phoretic mites and their complex relationships with these two bark beetles species. The research was conducted in a stand located at the lower limit of spruce, where the two pest species have developed outbreaks together. Over 50,000 beetles were collected using wing-type pheromone traps, of which 4,348 were analyzed for the determination of phoretic mites (2,413 I. typographus; 1,935 I. duplicatus). In total, nine species of phoretic mites were identified, of which only six were found on Ips duplicatus. Among the nine species, Dendrolaelaps disetus Hirschmann, 1960 (Digamasellidae), Elattoma sp. (Pygmephoridae), and Paraleius leontonychus Berlese, 1910 (Oribatulidae) are reported for the first time in Romania. The results showed that although Ips typographus beetles carried significantly more phoretic mites than Ips duplicatus throughout the entire flight period, both species exhibited similar peaks in phoresy rate. ONE-WAY PERMANOVA test revealed significant differences between the two phoretic mite communities, differences also highlighted by diversity indices. These differences are most likely due to the presence of certain mite species only on I. typographus beetles, as well as differences between the populations of common species. The phoretic attachment location on host beetles varied across mite and host beetle species.</p>","PeriodicalId":12088,"journal":{"name":"Experimental and Applied Acarology","volume":"95 3","pages":"35"},"PeriodicalIF":1.7,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12378774/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144948019","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}
