Temperature‐dependent development of Neoseiulus barkeri (Acari: Phytoseiidae) on Tetranychus urticae (Acari: Tetranychidae) at seven constant temperatures

Abstract  The effect of seven constant temperatures of 15, 20, 25, 27, 30, 35 and 37°C on developmental time of Neoseiulus barkeri Hughes were determined in laboratory conditions under 65%± 5% RH and a photoperiod of 12 : 12 (L : D) h on nymphal stages of Tetranychus urticae Koch. Total developmental time of females (from egg to adult emergence) at the above‐mentioned temperatures was 26.59, 14.43, 6.32, 5.64, 4.59, 3.98 and 4.67 days, respectively. Developmental rate of the N. barkeri increased as temperature increased from 15 to 35°C, but declined at 37°C. A linear and two nonlinear models were fitted to developmental rate of immature stages of N. barkeri to predict the developmental rate as a function of temperature, as well as to estimate the thermal constant (K) and critical temperatures (i.e., Tmin, Topt and Tmax). The estimated values of the Tmin and K for total developmental time using the linear model were 12.07°C and 86.20 degree‐days (DD), respectively. The Tmin and Tmax estimated by the Sharpe‐Schoolfield‐Ikemoto (SSI) model were 11.90°C and 37.41°C, respectively. The estimated Topt for overall immature stage development of N. barkeri by the Lactin and SSI models were 33.89°C and 24.51°C, respectively. Based on the biological criteria of model evaluation, the linear and SSI models were found to be the best models for describing the developmental rate of overall immature stages of N. barkeri and estimating the temperature thresholds.

Demographic response to constant temperatures in Neoseiulus barkeri (Phytoseiidae) fed on Tetranychus urticae (Tetranychidae)

Abstract The effect of temperature on survivorship, reproduction, adult longevity, population growth parameters, fecundity and sex ratio of the predatory mite Neoseiulus barkeri Hughes fed on nymphal stages of Tetranychus urticae Koch was determined at seven constant temperatures of 15, 20, 25, 27, 30, 35 and 37°C. Fitting adult survival data to Weibull frequency distribution indicated that the adult survival curve was type I at all temperatures tested, which means most deaths occurred among older individuals. The values of the life table entropy at the temperature range of 15–37°C (H < 0.5) correspond to type I Slobodkins survivorship curve. The oviposition period and female and male adult longevity decreased as temperature increased from 15 to 37ºC. The highest value of the net reproductive rate (R0) was 22.02 females/female at 25°C.The longest and shortest female longevity were 86.28 and 20.5 days at 15 and 37°C, respectively. Furthermore, the highest and lowest values of the intrinsic rate of increase (rm) were 0.256 and 0.036 females/female/day at 30 and 15ºC, respectively. The relationship between temperature and rm of N. barkeri was modeled and critical temperatures including Tmin, Topt and Tmax for intrinsic rate of increase were estimated at 13.51, 32.20 and 39.92°C, respectively using the Lactin 2 model. Moreover, the mean generation time (T) decreased significantly from 47.18 to 8.51 days with increasing temperature from 15°C to 37°C. The shortest and longest doubling times (DT) were 2.71 and 19.16 at 30°C and 15°C, respectively. The results of this study indicated that N. barkeri has inherent potential for the control of two-spotted spider mite at higher temperatures especially at temperatures between 30–35°C.

Stigmaeid mites associated with stored rice in northern Iran (Acari: Stigmaeidae)

Abstract During a survey on the mites associated with stored rice and decayed rice bran in northern Iran, Guilan province, four species of Stigmaeidae (Acari: Prostigmata) were found. All four species, namely Stigmaeus elongatus Berlese, Stigmaeus candidus Fan and Li, Storchia pacifica (Summers) and Storchia robusta (Berlese), are new to the fauna of Guilan province, and S. pacifica is new to Iran. Keys are provided for all the species of Storchia in the world and species of Stigmaeus found in Iran and neighboring countries. Stigmaeus mazandaranicus Faraji and Ueckermann is recognized as a junior synonym of S. candidus.

A checklist and a key for the Phytoseiidae species of Turkey with two new species records (Acari: Mesostigmata)

ABSTRACT A checklist and a key are given for the 62 species of Phytoseiidae of Turkey. Two species Neoseiulus marginatus (Wainstein) and Transeius wainsteini (Gomelauri), which are new records from Turkey, as well as Transeius herbarius (Wainstein) are redescribed. Amblyseius enab El-Badry, Amblyseius rusticana Athias-Henriot, Typhlodromus tenuis Westerboer, and Typhlodromus intercalaris Livshitz and Kuznetsov are recognized as suspected junior synonyms of Amblyseius swirskii Athias-Henriot, Amblyseiella setosa Muma, T. herbarius (Wainstein), and Typhlodromus (Anthoseius) invectus Chant, respectively. We accept a previous conclusion on the species concept of Phytoseius plumifer (Canestrini and Fanzago) and consider removing Phytoseius finitimus Ribaga from synonymy with P. plumifer.

Re-descriptions of Amblyseius meghriensis Arutunjan and Typhlodromus haiastanius (Arutunjan) with discussion on using preanal pores as a character in the subgenus Anthoseius (Mesostigmata: Phytoseiidae)

ABSTRACT Amblyseius meghriensis Arutunjan (1968), collected in Lorestan Province, is a new species record for the Iranian phytoseiid fauna. The female is re-described and the male is described for the first time. The morphological characters of the female specimens collected from Iran compared with those given in the original description from Armenia. Illustrations and measurements are also given for the Typhlodromus (Anthoseius) haiastanius (Arutunjan), another new species record for Iran. We have found that the presence of preanal pores can be variable in T. (A.) khosrovensis Arutunjan. The significance of this morphological character in the taxonomy of the subgenus Anthoseius is discussed. A key to the species of Amblyseius recorded from Iran is also given.

A new species of Hoploseius berlese from iran (Acari: Podocinidae)

Abstract Mites of the genus Hoploseius Berlese have been found associated with fungi and have phoretic associations with some fungal insects. The female and male of Hoploseius bispinosetus n. sp. collected from wood fungi and decomposing wood in north of Iran are described and illustrated. This new species is easily distinguished from the other species in the genus Hoploseius by its enlarged and spine-like I 4 dorsal setae.

A new Hattena Domrow (Acari: Ameroseiidae) from ecuadorian mangroves and a new generic record for South America

Abstract Mites of the genus Hattena Domrow primarily inhabit flowers and found phoretic on flower-visiting animals. Hattena rhizophorae n. sp. (Ameroseiidae) from flowers is described and illustrated herein. It is a new generic record for the American continent. Deutonymphs and adult stages of both sexes of H. rhizophorae were found in the flowers of red mangrove trees (Rhizophora mangle L., Rhizophoraceae) in Rio Chone estuary located in the province of Manabi, on the Pacific coast of Ecuador.
