The suitability of eight pollen diets (wild almond, date palm, oak, pomegranate, pistachio, peach, damask rose, and walnut) and also Tetranychus urticae Koch as natural diet on life table of the Amblyseius swirskii (Phytoseiidae) was determined at 25 ± 1 °C, 60 ± 5% relative humidity and photoperiod of 16:8 h (L: D). Results showed that damask rose pollen was not accepted as food and did not support the development of A. swirskii beyond the protonymphal and deutonymphal stage. The highest and lowest values of the intrinsic rate of increase (r) and finite rate of increase (λ) belonged to the pistachio (0.192 and 1.212 day−1) and peach (0.022 and 1.023 day−1) pollen, respectively. The net reproductive rate (R0) values varied from 1.4 offspring for the peach pollen to 29.54 offspring for the pistachio. Furthermore, the highest and lowest fecundity rate was recorded on the pistachio (36.65 eggs/female) and peach (3.23 eggs/female) pollen, respectively. Measured life table parameters of A. swirskii reared on different diets revealed pistachio, and after that, date palm and pomegranate pollen grains to be the most suitable diets. These findings may introduce more suitable pollen diets for the rearing of this predatory mite.

Birjandtrombella farniae Noei, 2020 was described from larvae ectoparasitic on moths (Lepidoptera: Crambidae, Noctuidae, Pyralidae), from Birjand city, South Khorasan province, Iran (Noei and Rabieh 2020). Based on Mąkol and Wohltmann (2012, 2013) the family Neotrombidiidae Feider, 1955 consists of four genera including Discotrombidium Feider, 1977, Monunguis Wharton, 1938, Neotrombidium Leonardi, 1901 and Anomalothrombium Andre, 1936. Discotrombidium and Anomalothrombium are based on post-larval forms only, the monotypic genus Monunguis (Parasitic on bat flies, Streblidae) is based on larva only (Womersley 1963) and Neotrombidium (Parasitic on subcortical beetles of the families Cerambycidae, Cleridae, Elateridae and Tenebrionidae, and on the ground beetle family Carabidae) is based on both larval and post-larval forms. The genus Neotrombidium includes 21 species which among them 13 species are based on larvae or adults and larvae (Mąkol and Wohltmann 2012, 2013; Noei et al. 2017) In this paper, the monotypic genus Birjandtrombella Noei, 2020 (Parasitic on Lepidoptera: Crambidae, Noctuidae, Pyralidae) is transferred from Trombellidae Thor, 1935 to the family Neotrombidiidae and the generic diagnosis is amended. The identification key to the genera of larval Trombellinae is amended, also.

A compilation of halacarid mite species (Halacaridae) found associated with decapod crustaceans (Arthropoda, Crustacea, Decapoda) has been carried out based on published records. In this paper, we listed 24 species associated with crustaceans altogether. These 24 species belong to 10 genera, viz. Arhodeoporus (1 species), Astacopsiphagus (1 species), Copidognathus (11 species), Halacarellus (2 species), Limnohalacarus (1 species), Lohmannella (1 species), Porohalacarus (1 species), Porolohmannella (1 species), Soldanellonyx (2 species), Thalassarachna (3 species). Majority of the association types are probably commensals or occasional invaders in nature and only a few species are assumed to be parasitic.

During a study, two tick species viz. Amblyomma gervaisi and Am. helvolum were collected from snakes covering 15 species belonging to 12 genera. The period of extended survey of snake- tick association was undertaken from 2009 to 2015 covering both natural and captive habitats from six districts of West Bengal, India. It was observed that Am. gervaisi mostly prefers Naja naja, Daboia russelii and Ptyas mucosa as host, whereas Am. helvolum prefers N. kaouthia and Bungarus fasciatus. Naja kaouthia is preferred as host by both Am. gervaisi and Am. helvolum. Eryx johnii and Gongilophis conicus are found to be infested by both Am. gervaisi and Am. helvolum, whereas Python molurous is only infested by Am. helvolum. No ticks are found to associate with six snake species viz., Xenochrophis piscator, Lycodon aulicus, L. jara, Ahaetulla nasuta, Chrysopelea ornata, and Boiga trigonata. It is noted that tick loads on host snakes in natural habitats is greater than captivity, with few negligible exceptions. Statistical analysis of tick prevalence and abundance are done stating that Am. gervaisi is dominant snake infesting tick compared to Am. helvolum in West Bengal. Species population of both Am. gervaisi and Am. helvolum denote female's domination with low species specificity.

Pesticide-resistant populations of the two-spotted spider mite, Tetranychus urticae Koch, have been reported in many countries. This problem has led to the search for alternative control methods. One of these alternative strategies is aqueous ozone. During a series of preliminary test, the effect of different concentrations of aqueous ozone on mortality of T. urticae on pepper (Capsicum annuum L.) was evaluated in greenhouse conditions at 25 ± 2 °C; 50 ± 5% RH and 16:8 (L:D) photoperiod. Then efficacy of ozone to control the pest was evaluated in different experimental conditions including three exposure times (5, 10 and 15 seconds), different time of spraying (8 am, 2 pm and 8 pm), and different ages of the host plant (4, 8 and 12 weeks old). Each experiment was carried out in a randomized complete design with six replications. Based on the screening tests, ozone concentration of 43 g/m3 was found to give efficient results in terms of mortality rates of the mites and morphological traits of the host plant. The mortality rate of the mites increased with increasing exposure time. Although the interaction effect between ozone concentration and exposure time was significant, in other experiments, no significant difference in the mortality percentage of the mite among either times of application, or ages of the host plant was found. In none of these experiments, no symptom of injury to the host plant foliage such as chlorosis, necrosis, yellowing or malformation was observed after aqueous ozone spraying. Based on these results, aqueous ozone at a specific concentration and conditions can reduce the population density of T. urticae without any visible damage on the pepper foliage. However, more research needs to be done before ozonated water can be deployed commercially as a pesticide.

Although the interaction effect between ozone concentration and exposure time was significant, in other experiments, no significant difference in the mortality percentage of the mite among either times of application, or ages of the host plant was found. In none of these experiments, no symptom of injury to the host plant foliage such as chlorosis, necrosis, yellowing or malformation was observed after aqueous ozone spraying. Based on these results, aqueous ozone at a specific concentration and conditions can reduce the population density of T. urticae without any visible damage on the pepper foliage. However, more research needs to be done before ozonated water can be deployed commercially as a pesticide.","PeriodicalId":37567,"journal":{"name":"Persian Journal of Acarology","volume":"10 1","pages":"95-106"},"PeriodicalIF":1.3,"publicationDate":"2021-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43829529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
