[Lamiaceae] essential oil (EO) and its nanoemulsion (NE) against Haemaphysalis longicornis nymphs. Pogostemon cablin EO nanoemulsion (PCNE) was prepared by ultrasonic emulsification using P. cablin EO and a surfactant, Tween 80. The results of gas chromatography–mass spectrometry analysis showed that the major component of P. cablin EO was patchouli alcohol (32.04%), followed by δ-guaiene (18.13%), α-guaiene (16.76%), seychellene (7.49%), and β-patchoulene (5.09%). The droplet sizes of PCNEs formulated using P. cablin EO and Tween 80 in ratios of 1:1, 1:2, and 1:3 were 23.8, 20.1 and 17.7 nm, respectively, indicating that the increase in the ratio of Tween 80 led to a decrease in droplet size. All essential oil preparations had an acceptable polydispersity index of 0.5 or less. The P. cablin EO and Tween 80 ratio of 1:3 was selected as the optimal formulation with the smallest droplet size; transmission electron microscopy indicated the formation of uniform spherical droplets. PCNE (84.0%) showed a higher repellent activity against H. longicornis nymphs than P. cablin EO (72.0%). The nanoemulsion is suitable for improving the repellent activity of P. cablin EO and is a potential repellent for H. longicornis.","PeriodicalId":13803,"journal":{"name":"International Journal of Acarology","volume":"48 1","pages":"466 - 471"},"PeriodicalIF":1.1,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47889311","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}

However, the frequent use of these products, resistance problems and severe problems with contamination occur. Therefore, one of the promising solutions is plant acaricides, which can be developed based on essential oils. Thus, the objective of this work was the extraction and characterization of the essential oil from the leaves of Kermani lemongrass, Dracocephalum polychaetum, and acaricidal evaluation of the oil and its major compound using the application by fumigation on female adults of Tetranychus urticae. The composition of the essential oil was analysed by GC-MS. The major components in the oil were 1-octen-3-ol (11.27%), 6-methyl-5-hepten-2-one (11.06%), linalool (9.89), and nonanal (9.64%), respectively. The impact of essential oil of this plant on fumigant toxicity, LT50, oviposition deterrent activity, and repellency against T. urticae was studied at different concentrations. The results stated that D. polychaetum oil had high toxicity on eggs and adults of two-spotted spider mite (LC50 was 60.30 and 50.87 µL L−1 for eggs and adults, respectively) with LT50 of 8.02 h. In addition, all tested concentrations had oviposition deterrent activity and repellency in adults of this mite.","PeriodicalId":13803,"journal":{"name":"International Journal of Acarology","volume":"48 1","pages":"503 - 509"},"PeriodicalIF":1.1,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46997325","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}

A major target is the ubiquitous mite Tetranychus urticae (Koch). A major factor limiting the effectiveness of natural enemies in biological control programmes is unfavourable climatic conditions at the release site. This study aimed to determine the climatic envelopes of N. californicus and N. idaeus to predict the geographical areas with the highest climatic suitability of each species where its efficacy as a biological control agent would be maximized. Site occurrence data and the associated environmental variables were obtained from pre-existing spatial information found in online databases. These data were analysed using the MaxEnt software to map the geographic areas worldwide most suitable for each species. The climate suitability for N. californicus was especially limited by conditions of high temperature, while limiting factors for N. idaeus were annual variation in temperatures and low annual precipitation. Suitable areas for N. californicus were observed in all five continents, concentrated in latitudes close to the tropics of Cancer and Capricorn. In relation to N. idaeus, suitable areas were observed on four continents and are concentrated in countries close to the Equator, particularly those in the southern hemisphere. N. californicus and N. idaeus have distinct climate suitability areas. The results may be helpful for selecting the predator species for introduction.","PeriodicalId":13803,"journal":{"name":"International Journal of Acarology","volume":"48 1","pages":"494 - 502"},"PeriodicalIF":1.1,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43208631","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}

The aim of this study was to focus on the acaricidal efficacy of bitter almond powder and bitter almond extracts (aqueous and alcoholic) against the nymph and adult stages of two tick species. It was evaluated at five different concentrations (1% to 5%) with bitter almond powder, bitter almond extracts, and alpha-cypermethrin (1 ml/100 ml) at four different exposure times (24, 48, 72, and 96 hours). The effectiveness of bitter almond alcoholic extract was significantly higher than the aqueous extract, and effectiveness was lowest with the powder at all concentrations at different exposure times for both species. Furthermore, aqueous and alcoholic extracts showed a higher mortality rate among both species than alpha-cypermethrin. LC50 value showed that the toxicity level of bitter almond acaricides increased with the longer exposure time and higher concentration. Toxicity level decreased in the order of alcoholic > aqueous > powder on both species. For both species, the highest toxicity level of bitter almond alcoholic extract was shown for the adult than nymph. Therefore, extracts of bitter almond can be used as an excellent acaricidal alternative to alpha-cypermethrin against these two species.","PeriodicalId":13803,"journal":{"name":"International Journal of Acarology","volume":"48 1","pages":"450 - 456"},"PeriodicalIF":1.1,"publicationDate":"2022-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49256642","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}
