The tomato red spider mite, Tetranychus evansi, is an important invasive pest of solanaceous plants worldwide. China is a potentially suitable region for T. evansi but there was no official record of its distribution. In this study, we reported five new records of T. evansi from eggplant, tomato and cucumber in southern and southwest China. The invasion of T. evansi constitutes a new threat to solanaceous crops in mainland China.
A new species viz. Eustigmaeus kulaensissp. nov., collected from soil and litter under Rubus sanctus (Rosaceae), Typha angustifolia (Typhaceae), Pinus brutia (Pinaceae) and Juglans regia (Juglandaceae) in Kula district, Manisa province, Turkey, is described and illustrated based on adult females. A key to the species of Eustigmaeus from Turkey is provided.
Four new species of eriophyoid mites (Acari: Trombidiformes: Eriophyoidea) were collected from native plant species from Pampa biome, in the state of Rio Grande do Sul, Brazil, and are described and illustrated herein. They have been named: Aculus pampae sp. nov. on Elephantopus mollis Kunth (Asteraceae); Costarectus lanceatus sp. nov. on Sebastiania brasiliensis Spreng. (Euphorbiaceae); Dichopelmus sigfeminae sp. nov. and Rhynacus symflori sp. nov. both on Symplocos uniflora (Pohl) Benth. (Symplocaceae). All new species appeared to be vagrants and no apparent symptom was associated to them.
This study was conducted to determine mite species in dried figs in Aydin, Turkey between August 2014 and November 2016. A total of 141 dried fig samples were taken from producers' storage, commercial storages and fig processing factories in Buharkent, Germencik, Incirliova, Kocarli, Kosk, Kuyucak, Merkez, Nazilli, Sultanhisar and Yenipazar districts. In addition, 24 dried fig samples were kept in storage for 8 months and the changes in mite species composition and their densities in stored figs were determined. As a result, 8 mite species belonging to 3 orders and 5 families were identified from the dried figs. Acarus siro L., Carpoglyphus lactis (L.), Glycyphagus destructor (Schrank), G. domesticus (De Geer) and Tyrophagus putrescentiae (Schrank) as pest species, and Blattisocius tarsalis (Berlese), B. mali (Oudemans) and Cheyletus eruditus (Schrank) as predatory mite species were found. Out of 141 samples, 133 were infested with mites and the infestation ratio was 94.3%. Tyrophagus putrescentiae was the most common pest species with an infestation rate of 72.3%, followed by C. lactis with 34.8%, A. siro. G. destructor and G. domesticus with 0.7% contamination, respectively. Carpoglyphus lactis was found to have the highest density with 10,488 individuals/ kg in contaminated fig samples. Blattisocius tarsalis was the most common predatory mite species with an infestation rate of 77.3%. Blattisocius mali and C. eruditus were found in 9.2% and 4.3% of dried figs, respectively. This study showed that the dried fig samples kept in storage were always vulnerable to contamination with mites. Mite species composition and their densities also fluctuated over time.
Two new species and an additional record of eriophyid mites from semi-arid and arid environments in East Iran are reported. Aculops ammodendris sp. nov. from Ammodendron persicum Bunge ex Boiss. (Leguminosae) and Aceria launaeae sp. nov. from Launaea acanthodes (Boiss.) Kuntze (Asteraceae) are described and illustrated. No symptoms were observed on the infested host plants. These two new species are the first eriophyid mites on plant species within the genera Ammodendron and Launaea. Geographical distribution of Aceria angustifoliaeDenizhan, Monfreda, de Lillo & Çobanoglu, 2008, extended also into the currently studied Iranian area in addition to a previous record from Turkey and Northern Khorasan.
Two new species of the genus Raphignathus Dugès (Acari: Raphignathidae); R. hamooniensis sp. nov., and R. tamaricis sp. nov., are described based on adult female specimens associated with salt seder trees (Tamaricaceae: Tamarix aphylla L.) in the Sistan region, Sistan and Baluchestan province, southeast Iran.
Pyemotid mites are parasitoids of various insects and are of potential as biocontrol agents. Three New Zealand new species of the genus Pyemotes are described in this paper: Pyemotes cumberi sp. nov. parasitic on Procecidochares utilis (Diptera: Tephritidae) in Auckland, Pyemotes martini sp. nov. parasitic on eggs of Scolypopa (Hemiptera: Ricaniidae) in the Northland, and Pyemotes mayae sp. nov. parasitic on scolytid larvae (Coleoptera) in Auckland. Keys to both adult males and females of these three new species are provided.
The fauna of Typhlodrominae in Pakistan (Acari: Phytoseiidae) includes five genera and 54 nominal species, reported from different agroecosystems and climatic zones of the country. The most diverse genera are Typhlodromus Scheuten (37 species) and Kuzinellus Wainstein (13 species). Two species of Chanteius Wainstein, and one species each of the genera Cydnoseius Muma and Neoseiulella Muma have been reported. Two species previously placed in Typhlodromus are here transferred to Chanteius, due to the absence of seta s6 and presence of Z1. Two species, T. (Anthoseius) hadii Chaudhri and T. (Anthoseius) maracus (Chaudhri), are re-described with improved descriptions and illustrations. Four species previously placed in Typhlodromus are considered as synonyms of Cydnoseius negevi (Swirski & Amitai 1961). Typhlodromus (Anthoseius) divergentis (Chaudhri, Akbar & Rasool) is considered as a synonym of T. (Anthoseius) egypticus El-Badry, and T. husaini Khan is considered as species inquirenda. A provisional key to the species of Typhlodrominae in Pakistan is provided.
A new monotypic genus, Ivoria taiensis gen. nov., sp. nov. (Mesostigmata: Uropodina: Uropodinychidae) is described on the basis of seven females collected in soil samples from Ivory Coast. The new genus has large and robust chelicerae, but it differs from the other Uropodina genera having similar chelicerae in several characters, which are presented in a comparative table. The new genus is placed in the family Urodinychidae based on its long setae h1, chelicerae with an internal sclerotized node, fixed digit of chelicerae apically smooth and devoid of apical processes, corniculi smooth.
Two species of Oligonychus are redescribed: O. baipisongisMa & Yuan, 1976 and O. chamaecyparisaeMa & Yuan, 1976. Moreover, O. hainanensisMa, Yuan & Lin, 1979 is here recognized as a junior synonym of O. biharensis (Hirst, 1924), which is also redescribed here based on adult females, males and deutonymphs. The redescription of O. baipisongis is based on holotype and paratypes, the types of O. chamaecyparisae could not be located but the species is described from male and female material collected by En-Pei Ma in 1978 from Lanzhou City, Xi-An City and Xining City. The dorsal setae in O. baipisongis show remarkable sexual dimorphism. The difference between the aedeagi of O. chamaecyparisae and Oligonychus perditusPritchard & Baker, 1955 are discussed. All three species are diagnosed, illustrated with line drawings and photographs.
A new species of Orangescirulinae, Orangescirula lii Chen & Jin sp. nov., is described and illustrated. It is characterized by having 2 claw-like setae, no solenidion and adorsal setae on palpal tibiotarsus, having 5 pairs of hysterogastral setae, 1 bsl and 5 sts on tibia III, 1 asl and 3 bsl on tarsus I. A key to adult females of Orangescirula of the world is provided.
