ABSTRACT In this study, the side effects of LC30 and LC50 concentrations of Rosmarinus officinalis L. (Lamiaceae) essential oil on the life table parameters of Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) fed on first instar Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) larvae were determined under lab conditions. The age-stage, two-sex life table method was used to evaluate the life table parameters. The net reproductive rate (R0) (8.76, 8.68 and 6.83 eggs per individual), intrinsic rate of increase (r) (0.116, 0.116 and 0.098 day −1), finite rate of increase (λ) (1.123, 1.123 and 1.103 day −1), mean generation time (T) (18.7, 18.6 and 19.6 days) and total fecundity (19.77, 19.00, and 17.70 offspring per female) acquired for control, LC30 and LC50 applications, respectively. The findings of this study indicate that using the tested essential oil, particularly the LC30, in combination with A. swirskii can be an alternative to synthetic pesticides. However, semi-field and field studies are still needed to assess the effects of the essential oil tested on F. occidentalis and A. swirskii before incorporating into integrated pest management (IPM) strategies.

ABSTRACT The predatory mite Neoseiulus californicus (McGregor) (Acari: Phytoseiidae) is a key natural enemy applied in phytophagous mite control in agricultural production areas. This study is aimed at investigating the development of pyridaben resistance as a result of the selection pressure under laboratory conditions on N. californicus mites, the inheritance of pyridaben resistance in this predatory mite, and the relationship of resistance with target region mutations. Pyridaben resistance levels were evaluated using a leaf disc spraying tower method. As a result of seven selections, 270-fold pyridaben resistance was identified in N. californicus. As a result of inheritance studies, pyridaben resistance in F1 females resulted from incomplete dominance and sex. Neoseiulus californicus was resistant to pyridaben and there was no significant difference in the monooxygenase enzyme levels in respect to the initial population. No amino acid changes were detected in the PCR evaluations of target site mutations in the pyridaben-resistant and initial populations of N. californicus. Increased pyridaben resistance in the selected population was thought to be caused by more mechanisms other than target site mutations.

ABSTRACT Dermatophagoides farinae (Astigmata: Pyroglyphidae) occurs in both homes and storage environments. The species produces biochemically diverse allergens that cause allergic reactions and seriously endanger human health. Habitat diversity can lead to divergent adaptive selection and reduced gene flow, thereby increasing genetic drift; both factors contribute to genetic differentiation. However, there is a lack of research concerning the genetic diversity and differentiation of D. farinae in different habitats. In this study, the genetic diversity and differentiation of D. farinae populations in different habitats were studied using the mitochondrial cytochrome b (Cytb) gene, the cytochrome c oxidase subunit I (COI) gene, and the ribosomal internal transcribed spacer (ITS) region. Both pillow cores (ZX) and dormitory (SS) habitats had higher haplotype diversity than the flour mill (MF) habitat. The reasons for this phenomenon are likely to be food availability as well as differences in temperature and humidity among habitats. There was significant genetic differentiation (Fst > 0.05, P < 0.05) between the ZX and MF and between the MF and SS habitats, but there was no significant genetic differentiation between the ZX and SS habitats (Fst < 0.05, P > 0.05) based on both Cytb and COI genes, reflecting the difference between mitochondrial and nuclear genes. The low level of gene flow observed for ZX-MF and MF-SS and the gene flow between the ZX and SS habitats supported the above results. A haplotype network and a neighbour-joining phylogenetic tree showed that individuals from the ZX and SS habitats occurred in two clades without a clear distribution boundary, indicating that the genetic structure was not correlated with the habitat distribution. This research is the first genetic analysis of D. farinae in different habitats. The study can improve our understanding of the population genetics of D. farinae in different habitats and aid in the development of more effective management strategies.

ABSTRACT The sugarcane rust mite (SRM), Abacarus sacchari, infests sugarcane in the Everglades Agricultural Area in southern Florida. Reddish-brown symptoms associated with SRM feeding on leaves appear in April and reach their peak in August-September. Mite dispersal plays an important role in habitat colonization. However, SRM dispersal in sugarcane fields has not yet been explored because of its microscopic size. This study aimed to determine the role of aerial dispersal in the colonization of sugarcane fields. Mite dispersal was studied by measuring aerial mites and mite population on the sugarcane canopy with the elimination of possible ambulatory movement among plants. In addition, the potential dispersal using ambulatory movement as well as precipitation was also investigated. The result suggests that aerial dispersal was the most important method for SRM dispersal. Moreover, females predominated airborne mites, comprising approximately 90% of those measured with 60% gravidity. This strong female bias and its high gravidity in airborne mites further demonstrate the potential role of aerial dispersal in the colonization of sugarcane fields.

ABSTRACT Tetranychus piercei (Acari: Tetranychidae) is a spider mite that infests a wide range of plants. It is difficult to control due to its ability to quickly develop resistance to common pesticides. The study aimed to find the effect of relative humidity (55, 75, and 95 ± 2% RH) on the efficacy of the entomopathogen Cordyceps tenuipes (1 × 106, 1 × 107 and 1 × 108 conidia/ml) against the egg and adult female stages of T. piercei. The results showed that the mortality of T. piercei eggs was concentration-dependent and that RH has a synergistic effect on efficacy. The egg mortality increased with the increasing the concentration from 1 × 106 to 1 × 108 conidia/ml at the same RH condition, and it was significantly higher at 1 × 108 conidia/ml at 95% RH than at 75 and 55% RHs. The median lethal time (LT50) for adult females was 41.1 hours at 95% RH and 49.8 hours at 75% RH when treated with a concentration of 1 × 108 conidia/ml. This was significantly lower than the LT50 values at other relative humidity levels and concentrations. The results of the study on potted bean plants showed that double spray of C. tenuipes was effective in controlling T. piercei infestations at a concentration of 1 × 108 conidia/ml. With a single spray of C. tenuipes, the mite population tends to be reduced initially and then increased subsequently. Thus, considering RH and incorporating other strategies is important when using biological control methods to effectively control this pest.

ABSTRACT The majority of animals possess claws on their legs and they are mainly used for keeping attached to the substrate. Recent studies on claw shapes and function suggest that claws are not just simple attachment devices but highly specialized morphological traits bearing information about lifestyle, ecology and evolution. In that respect, knowledge about claws is extremely scarce, especially in highly diverse groups, as for example the oribatid mites, with more than 11000 named species occurring in every environment all over the world. This review summarizes all information about claws and relevant aspects for this large group of arthropods. There is a huge variety of ambulacral claw morphologies present in oribatid mites and this diversity does not follow a strict phylogenetic or systematic pattern. Lifestyle and ecology apparently play an important role in shaping claw morphologies. Intertidal oribatid mites are mostly characterized by having single large tarsal claws to withstand tidal flooding, a similar tendency can be found in terrestrial limnic species where monodactylous species prevail. Additionally, fresh-water Oribatida often show scaliform and barbed distal tarsal setae which cooperate with the claws helping the mites to stick to water plants. Claws of arboreal mites are often equipped with adhesive pads “pulvilli” allowing them to walk on smooth plant surfaces. Suction pads are also found in a few mites showing epilithic lifestyles and in mites being able to perform sudden evasive jumps. Claws of phoretic oribatid mites show in most cases no apparent adaptations but certain groups are equipped with highly modified claws allowing them to attach to specific structures of their hosts. Finally, this review gives an overview of all claw morphologies present in each larger phylogenetic oribatid mite group.

Additionally, fresh-water Oribatida often show scaliform and barbed distal tarsal setae which cooperate with the claws helping the mites to stick to water plants. Claws of arboreal mites are often equipped with adhesive pads “pulvilli” allowing them to walk on smooth plant surfaces. Suction pads are also found in a few mites showing epilithic lifestyles and in mites being able to perform sudden evasive jumps. Claws of phoretic oribatid mites show in most cases no apparent adaptations but certain groups are equipped with highly modified claws allowing them to attach to specific structures of their hosts. Finally, this review gives an overview of all claw morphologies present in each larger phylogenetic oribatid mite group.","PeriodicalId":13803,"journal":{"name":"International Journal of Acarology","volume":"49 1","pages":"165 - 195"},"PeriodicalIF":1.1,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46146759","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}
