Identification of Haplothrips species from Malesia (Thysanoptera, Phlaeothripinae).
Zootaxa, 2019Co-Authors: Laurence A. MoundAbstract:A key is provided to 13 species of Haplothrips recorded from Malesia, the tropical biogeographic region that extends from Peninsular Malaysia to New Guinea. Three new synonyms are established, and H. aliceae sp.n . is described from Sarawak, Timor-Leste and Thailand. In contrast to recent treatments of Haplothrips , one of the most common members of the genus in Australia, H. angustus Hood is recognised as a syn.n. of H. ganglebaueri Schmutz that is widespread from Iran to Indonesia. Difficulties in distinguishing between three of the most common flower-living, Southeast Asian, species of this genus are discussed: H. anceps Hood from northern Australia, H. chinensis Priesner from Hong Kong, and H. brevitubus (Karny) from Japan.

Rediagnoses of the Asian genera Xylaplothrips and Mesandrothrips (Thysanoptera, Phlaeothripinae, Haplothripini), with keys to Australian species.
Zootaxa, 2019Co-Authors: Laurence A. Mound, Desley J. TreeAbstract:The genus Xylaplothrips is re-diagnosed, 11 species are listed as appropriately included in this genus of which three are new combinations from Haplothrips ( X. acaciae ; X. collyerae ; X. gahniae ). A further six species are listed as incertae sedis within Xylaplothrips and a key is provided to the four species of this genus known from Australia including X. anarsius sp.n. The genus Mesandrothrips is recalled from synonymy with Xylaplothrips , and a list is provided of 20 appropriately included species of which 14 are new combinations from Xylaplothrips ( M. caliginosus ; M. clavipes ; M. darci ; M. dubius ; M. emineus ; M. flavitibia ; M. flavus ; M. inquilinus ; M. montanus ; M. pictipes ; M. pusillus ; M. reedi ; M. subterraneus ; M. tener ), and one is a new combination from Haplothrips ( M. inquinatus ). A key is provided to 10 species of this genus known from Australia, including three species transferred from Haplothrips , together with M. austrosteensia sp.n. , M. googongi sp.n. , M. kurandae sp.n. , M. lamingtoni sp.n. and M. oleariae sp.n. The type species, M. inquilinus , is widespread across Southeast Asia as an invader of thrips galls, and Haplothrips darci Girault based on a single female from Queensland is considered closely related.

Predation, phytophagy and character state confusion among North American species of the genus Leptothrips (Thysanoptera: phlaeothripinae).
Zootaxa, 2017Co-Authors: Laurence A. Mound, Cheryle A. O’donnellAbstract:Difficulties are discussed of specimen preparation, of character state variation, and of species recognition in the genus Leptothrips , also the extent to which some of the species are phytophagous rather than predatory. An identification key is provided to 15 Leptothrips species from North America. Nine species described by Johansen (1987) are newly placed into synonymy, a further unrecognisable species is based on a single deformed specimen, and L. texcosensis Johansen-Naime et al . (2017) is transferred to the genus Haplothrips .

The species of Haplothrips (Thysanoptera, Phlaeothripinae) and related genera recorded from the Hawaiian Islands.
ZooKeys, 2017Co-Authors: Laurence A. Mound, Janis N. MatsunagaAbstract:An illustrated identification key is provided to 17 species of Thysanoptera: Phlaeothripinae from Hawaii that are members of the Tribe Haplothripini, together with a further species that is similar in general appearance to members of that Tribe. Of these 18 species, 13 are considered introduced from other parts of the world, but five appear to be endemics. Known only from Hawaii, Haplothrips fissussyn. n. is considered to have been based on a teratological specimen and is placed as a synonym of the Hawaiian endemic Haplothrips davisi. Both this species and two further endemics, Haplothrips rosai and Priesneria doliicornis, are possibly mycophagous rather than phytophagous. The Indonesian species Haplothrips sesuviisyn. n. is recognised as a synonym of Haplothrips robustus from Australia, although both names have been used in Hawaii. Two further species that are presumed to be Hawaiian endemics, Apterygothrips remotus and Haplothrips williamsi, remain known only from the original specimens.

New synonymy in the wheat thrips, Haplothrips tritici (Thysanoptera: Phlaeothripidae)
2015Co-Authors: Kambiz Minaei, Laurence A. MoundAbstract:The wheat thrips, Haplothrips tritici, is known from across eastern Europe and adjoining areas of Asia into western Europe and north Africa, and is widely regarded as a pest of cultivated cereal crops, particularly of Triticum but also of Hordeum (Özsisli 2011). The identity of this thrips species is not in doubt, but a closely similar species, Haplothrips cerealis, was described from Egypt (Priesner 1939), and subsequently recorded between southeastern Europe and Iran (see Minaei & Mound 2008). Priesner based this species on an unspecified number of specimens of both sexes, collected from the ears of cultivated wheat at “Wadi Gederât, Sinai”, and did not designate a holotype. Minaei and Mound (2010) indicated that they considered the records of cerealis from Iran to be based on misidentifications of tritici, but they suggested that further studies were required to determine if there is any evidence that these names represent different species in other countries. The problems arise because the published descriptions of, and comparisons between, the two species are confusing and sometimes contradictory. The objective of this report is to examine the published literature, and to consider this in relation to observed structural variation in recently collected samples as well as specimens in museums that are variously labeled as one or other of these two species. Literature references to females The original description (Priesner 1939) states that cerealis differs from tritici in having shorter postocular, prothoracic and abdominal setae that are sharply pointed, whereas those of tritici are rounded at the tip, and that cerealis also differ

A New Bicolored Haplothrips Species from Southern Iran (Thysanoptera: Phlaeothripidae)
Entomological News, 2018Co-Authors: Kambiz Minaei, Saeideh Mombeini, Leila RamezaniAbstract:Haplothrips navvabi sp. n. is described from two Chenopodiaceae plants from southern Iran. The new species is close to the Australian and New Zealand species, H. salicorniae and is the second member of subgenus Haplothrips (Trybomiella) in Iran. Illustrations are provided and H. navvabi is compared with related species in the genus.

Aeolothrips eremicola (Thysanoptera, Aeolothripidae): first record of the male from Iran.
Zootaxa, 2013Co-Authors: Jalil Alavi, Lida Fekrat, Mehdi Modarres Awal, Maryam Zolfaghari, Kambiz MinaeiAbstract:The genus Aeolothrips , with 17 recorded species, is the third most species-rich genus in Iran (Minaei 2013). In contrast, the genus Thrips includes 28 species in this country (Minaei 2012; Mirab-balou et al . 2012), and Haplothrips 24 species (Minaei & Aleosfoor 2013), Moreover, it seems likely that more species of Aeolothrips will be discovered in Iran, considering the number recorded from neighboring countries.

calculo del umbral economico de dano del trips del trigo Haplothrips tritici kurdjumov
1998Co-Authors: P Bielza, A Lacasa, Tecnologia AgraAbstract:BIELZA, P. y LACASA, A., 1998: Calculo del umbral economico de dano del trips del trigo, Haplothrips tritici (Kurdjumov). Bol. San. Veg. Plagas, 24(2): 239-250. For the wheat thrips, Haplothrips tritici, a calculation system was developed of the economic damage threshold in function of the potential production, the selling price and the cost of the treatment, considering the decrease of the production and the quality. For average productions and prices the economic damage threshold was 17 larvae per spike. To facilitate all the calculations the program TRITICI was developed.

patogenos y depredadores naturales del trips del trigo Haplothrips tritici kurdjumov en castilla la mancha
Boletín de sanidad vegetal. Plagas, 1998Co-Authors: Pablo Bielza Lino, Julio Cesar Tello Marquina, L Torres M Vila, M Rodriguez C MolinaAbstract:BiELZA, P.; TELLO, J. C ; TORRES VILA, L. M.; RODRIGUEZ MOLINA, M. C. y Ruiz TAPIADOR, I., 1998: Patogenos y depredadores naturales del trips del trigo, Haplothrips tritici (Kurdjumov), en Castilla-La Mancha. Bol. San. Veg. Plagas, 24( Adenda al n.° 4): 985-996. A two year sampling of pathogens and predators of Haplothrips tritici was carried out in Santa Olalla (Toledo) during the years 1994-96. Among the winter mortality factors was found the attack of the fungus Beauveria bassiana, there being differences of pathogenicity detected between isolates. Its incidence was higher in a dry year than in a wet year. Several potential predators of overwintering larvae were detected, two species of Carabidae, Paradromius linearis and Microlestes sp., and several species of spiders. On the spikes larvae and adults of Aeolothrips were found which, according to laboratory observations, prey upon eggs and larvae I of H. tritici. The larvae II are not Aeolothrips preys since they defended themselves with success, the predator-prey role being inverted, H. tritici depredating upon Aeolothrips larvae. In the spikes larvae of Chrysopa and Syrphidae were collected showing symptoms of feeding upon larvae of H. tritici, according to laboratory observations. Coccinella septempunctata did not feed upon larvae of H. tritici.
