Two new species of the family Syringophilidae (Acari: Cheyletoidea) from passeriform birds collected in the Altai

Two new species of the syringophilid mites (Acari: Syringophilidae) are described from quills of passeriform birds. Syringophilopsis faini sp. n. is described from Sylvia curruca (L.) (Sylviidae) and Syringophiloidus carpodaci sp. n. is described from Carpodacus erythrinus (Pall.) (Fringillidae). Characters are detailed that differentiate Syringophilopsis faini from three species of a new "turdus" group, and Syringophiloidus carpodaci from S. minor.

Three new quill mite species of the genus Syringophiloidus Kethley, 1970 (Acari: Syringophilidae) from Slovakia are described and figured: S. bombycillae sp. n. from the waxwing Bombycilla garrulus (L.) (Passeriformes: Bombycillidae), S. schoeniclus sp. n. from the reed bunting Emberiza schoeniclus L. (Passcriformes: Emberizidae) and S. montanus sp. n. from the tree sparrow Passer monlanus (L.) (Passeriformes: Ploceidae). A key to all known species of the genus Syringophiloidus is given.     

Chigger mites (Acari: Trombiculidae) from wild birds in Costa Rica, with a description of three new species

Three new species of chigger mites, Eutrombicula costaricensis sp. n., Eutrombicula passerinoruni sp. n., and Eutrombicula hectochaeta sp. n. are described from wild birds from Costa Rica. Two species, Eutrombicula pacae (Floch et Fauran, 1957) and Parasecia findata (Brennan, 1969), are recorded for the first time in Costa Rica and on new host species. Data on the distribution of Blankaartia sinnamaryi (Floch et Fauran, 1956) in Costa Rica are also reported.     

Hylomysobia gen. n. (Acari: Myobiidae), a new genus of mites parasitic on gymnures of the genus Hylomys (Eulipotyphla: Erinaceidae)

A new genus of Myobiidae, Hylomysobia gen. n. with two new species, H. mikhailzaitzevi sp. n. (type species) and H. chinensis sp. n., is described from gymnures of the genus Hylomys Müller (Eulipotyphla: Erinaceidae). The two species parasitize Hylomys suillus Müller from Cambodia and Vietnam, and Hylomys sinensis (Trouessart) from China, respectively. These species represent the first records of myobiid mites from species in the family Erinaceidae. The new genus differs from the closely related Eutalpacarus Jameson, 1949 by the following features: in both sexes, coxae I have a triangular process, setae ve are about three times wider than sce and c2, and coxae II bear two pairs of setae; in females, setae sci are lanceolate, setae ag1 and ag3 are absent, and the vulvar lobes are weakly developed; in males, setae e2 are absent, and setae c1, d1, d2 and e1 are situated on the genital shield. The life cycle of Hylomysobia spp. includes egg, larva, protonymph, deutonymph, and adults, male and female. In contrast to the most other myobiid genera possessing the tritonymphal stage, the deutonymphs of Hylomysobia moult directly to adults, and the tritonymphs are absent. Based on the restricted distribution of Hylomysobia species on hosts of this family (only on species of the genus Hylomys) and close morphological similarities to myobiids from Soricidae and Talpidae, it is suggested that the ancestor of this genus secondarily colonized the ancestor of Hylomys from moles or shrews.     

Chigger mites of the genus Eutrombicula ewing, 1938 (Acari: Trombiculidae) from Cuba, with the description of three new species

Three new species of chigger mites, Eutrombicula cubensis sp. n. and E. anguliscuta sp. n. from lizards and bats, and E. leiocephali sp. n. from lizards, are described. One species, E. lipovskyana (Wolfenbarger, 1953), is recorded for the first time in Cuba. Data on distribution of E. alfreddugesi (Oudemans, 1910) in Cuba are reported.     

Picobia polonica sp. n. (Acari: Prostigmata: Syringophilidae), a new species of quill mite from the domestic hen, Gallus gallus domesticus (Aves: Phasianidae).

Female, physogastric female and male of Picobia polonica sp. n. collected from the domestic hen Gallus gallus domesticus (L.) in Poland are described and the phenomenon of physogastry in this and related species is briefly discussed. Picobia polonica is similar to Picobia khulkhshani (Kivganov et Sharafat, 1995). These two species can be distinguished by the following characters: P. polonica: chelicerae dentate, each with three minute teeth; setae g1 and pg2 subequal in length; ratio pg1 : pg2, 3: 1. P. khulkhshani: chelicerae edentate; setae g1 twice shorter than pg2; ratio pg1 : pg2, 1.6: 1.     

A new genus of capillariids from birds, Tridentocapillaria gen. n. (Nematoda: Capillariidae)

A new genus of the family Capillariidae, Tridentocapillaria gen. n., has been established. A type species is Tridentocapillaria tridens (Dujardin, 1845) comb. n. Other species of this genus are T. eurycerca (Oschmarin et Parukhin, 1963) comb. n., T. parusi (Wakelin, Schmidt et Kuntz, 1970) comb. n., and T. javanensis (Wakelin, Schmidt et Kuntz, 1971) comb. n. The new genus is characterized by the presence of a trilobed pseudobursa formed by three processes, and a vulvar appendage is always present in females. The genus includes species parasitic in the intestine of birds of the orders Passeriformes and Piciformes.     

A new genus of capillariids from birds, Ornithocapillaria gen. n. (Nematoda: Capillariidae)

A new genus, Ornithocapillaria gen. n., belonging to the family Capillariidae and subfamily Baruscapillariinae is described and its diagnosis is given. The type species of the genus is Ornithocapillaria ovopunctata (Linstow, 1873) comb. n., other species are O. cylindrica (Eberth, 1863) comb. n., O. quiscali (Read, 1949) comb. n., and O. picorum (Rudolphi, 1819) comb. n. The new genus is characterized by a relatively large membranous pseudobursa, shape of processes supporting pseudobursa, and presence of a vulval appendage in female. It includes only species parasitic in the intestine of birds of the orders Passeriformes, Falconiformes, Strigiformes, and Piciformes.     

Effects of azadirachtin on Tetranychus urticae (Acari: Tetranychidae) and its compatibility with predatory mites (Acari: Phytoseiidae) on strawberry

BACKGROUND: The spider mite, Tetranychus urticae, is the major strawberry pest in Brazil. The main strategies for its control comprise synthetic acaricides and predatory mites. The recent register of a commercial formula of azadirachtin (Azamax^® 12 g L^?1) can be viable for control of T. urticae. In this work, the effects of azadirachtin on T. urticae and its compatibility with predatory mites Neoseiulus californicus and Phytoseiulus macropilis in the strawberry crop were evaluated. RESULTS: Azadirachtin was efficient against T. urticae, with a mortality rate similar to that of abamectin. In addition, the azadirachtin showed lower biological persistence (7 days) than abamectin (21 days). Azadirachtin did not cause significant mortality of adult predatory mites (N. californicus and P. macropilis), but it did reduce fecundity by 50%. However, egg viability of the azadirachtin treatments was similar to that of the control (>80% viability). The use of azadirachtin and predatory mites is a valuable tool for controlling T. urticae in strawberry crop. CONCLUSIONS: Azadirachtin provided effective control of T. urticae and is compatible with the predatory mites N. californicus and P. macropilis. It is an excellent tool to be incorporated into integrated pest management for strawberry crop in Brazil. Copyright © 2012 Society of Chemical Industry

Compatibility of spinosad with predaceous mites (Acari) used to control Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae)

BACKGROUND: Spinosad is a biopesticide widely used for control of Frankliniella occidentalis (Pergande). It is reported to be non‐toxic to several predatory mite species used for the biological control of thrips. Predatory mites Typhlodromips montdorensis (Schicha), Neoseiulus cucumeris (Oudemans) and Hypoaspis miles (Berlese) have been used for control of F. occidentalis. This study investigated the impact of direct and residual toxicity of spinosad on F. occidentalis and predatory mites. The repellency of spinosad residues to these predatory mites was also investigated. RESULTS: Direct contact to spinosad effectively reduced the number of F. occidentalis adults and larvae, causing > 96% mortality. Spinosad residues aged 2–96 h were also toxic to F. occidentalis. Direct exposure to spinosad resulted in > 90% mortality of all three mite species. Thresholds for the residual toxicity (contact) of spinosad (LT₂₅) were estimated as 4.2, 3.2 and 5.8 days for T. montdorensis, N. cucumeris and H. miles respectively. When mites were simultaneously exposed to spinosad residues and fed spinosad‐intoxicated thrips larvae, toxicity increased. Residual thresholds were re‐estimated as 5.4, 3.9 and 6.1 days for T. montdorensis, N. cucumeris and H. miles respectively. Residues aged 2–48 h repelled T. montdorensis and H. miles, and residues aged 2–24 h repelled N. cucumeris. CONCLUSION: Predatory mites can be safely released 6 days after spinosad is applied for the management of F. occidentalis. Copyright © 2011 Society of Chemical Industry     

Notes on mites of the family Myobiidae (Acari: Prostigmata) parasitising rodents (Mammalia: Rodentia) in Iran

Six mite species of the family Myobiidae, Radfordia (Austromyobia)persica sp. n., Radfordia (Austromyobia) merioni Bochkov, Dubinina et Chirov, 1990, Radfordia (Radfordia) acomys Fain et Lukoschus, 1977, Radfordia (Radfordia) affinis (Poppe, 1896), Radfordia (Graphiurobia) dyromys Fain et Lukoschus, 1973, and Myobia (Myobia) murismusculi (Schrank, 1781) were found in Iran on the rodents Gerbillus cheesmani Thomas, Meriones libycus Lichtenstein, Acomys cahirinus (Desmarest), Alus musculus L., Dryomys nitedula (Pallas), and Mus muscullus, respectively. R. (A.) persica is described as a new species from the female, male and tritonymph. The other five myobiid species are new to Iran.

Side effects of some fungicides on phytoseiid mites (Acari, Phytoseiidae) in north-Italian vineyards

The effects of fungicides containing mancozeb or copper oxychloride, as principal active ingredients, on phytoseiid mites were investigated in a vineyard comprising four varieties (Prosecco, Cabernet Franc, Pinot gris and Merlot) and located in north-eastern Italy. Phytoseiid colonisation was different among the four varieties: Amblyseius andersoni and Kampimodromus aberrans were dominant on Pinot gris and Merlot, respectively, while Typhlodromus pyri was more common than the above species on Prosecco and Cabernet Franc. Applications of mancozeb fungicides significantly affected K. aberrans populations. Concerning T. pyri, a significant effect was observed on Cabernet but not on Prosecco. The effects of mancozeb fungicides on A. andersoni were less clear. The response of phytoseiids to fungicides containing mancozeb appeared to be mediated by the variety. Therefore, the choice of one or two varieties as a standard reference for field tests is recommended. These results also suggest that the side effects of fungicides on predatory mites should be studied on different phytoseiid species and, possibly, on susceptible and resistant strains in order to gain useful insights.
