Derzsy’s disease causes disastrous losses in domestic waterfowl farms. A genetically variant strain of Muscovy duck parvovirus (MDPV) and goose parvovirus (GPV) was named novel goose parvovirus (NGPV), which causes characteristic syndrome in young ducklings. The syndrome was clinically characterized by deformity in beaks and retarded growth, called short beaks and dwarfism syndrome (SBDS). Ten mule and pekin duck farms were investigated for parvovirus in three Egyptian provinces. Despite low recorded mortality rate (20%), morbidity rate was high (70%), but the economic losses were remarkable as a result of retarded growth and low performance. Isolation of NGPV was successful on primary cell culture of embryonated duck liver cells with a clear cytopathic effect. Partial gene sequence of the VP1 gene showed high amino acids identity among isolated strains and close identity with Chinese strains of NGPV, and low identity with classic GPV and MDPV strains. To the best of our knowledge, this can be considered the first record of NGPV infections in Egypt.

Abstract In recent years, increased deforestation and replacement of areas intended for intensive cultivation have caused pathogens and parasites of Apis mellifera bees to emerge in regions where they had not previously been reported. Such is the case of the advancement of Ascosphaera apis, a fungus that causes a drop in colonies’ bee larvae population and great economic losses to beekeeping activity during severe cases. In northern Argentina, few studies have focused on this important entomopathogen. This is the first study on A. apis isolated from commercial pollen in Entre Ríos, Jujuy, and Misiones provinces, where its prevalence in bee colonies has not been reported. We identified this entomopathogen using macroscopic, microscopic, and molecular analyses, focusing on its botanical origin as a possible transmission route. We found the pathogenicity of each strain in A. mellifera bees to below 30%. The results of this study contribute to the promotion of sanitary measures that may reduce this disease’s progression in local apiaries.

The purpose of this note is to report the first record of Duplachionaspis divergens (Green, 1899) (Hemiptera: Diaspididae) in forage grasses in Brazil. Specimens of this armored scale were found in heavily degraded pastures, with yellowish and dry clumps of Ipyporã grass, a Urochloa hybrid. Previously, this species had been reported in Brazil only in sugarcane under greenhouse conditions. Its presence in forage grasses has caused visibly significant damage. The extent of the consequent economic losses has yet to be estimated.

A total of 482 chickpea (Cicer arietinum L.), 182 lentil (Lens culinaris Medik.), 12 vetch (Vicia sativa L.), 5 field pea (Pisum sativum L.), and 3 faba bean (Vicia faba L.) samples were collected from plants with symptoms suggestive of a viral infection (leaf rolling, yellowing, and stunting) from the major legume-production areas of Azerbaijan in the 2007 and 2008 growing seasons. All samples were tested by the tissue-blot immunoassay (3) at the Virology Laboratory of ICARDA, Syria using 11 specific legume virus antisera including a monoclonal antibody (2-5H9) (1) for Faba bean necrotic yellows virus (FBNYV). Laboratory tests showed that FBNYV was detected in 73, 61, 11, 3, and 2 samples of chickpea, lentil, vetch, field pea, and faba bean, respectively. Total DNA was extracted from six FBNYV-positive samples (two chickpea, two lentil, and two vetch) and tested by PCR with the following four primer sets (FBNYV, Milk vetch dwarf virus [MDV], Subterranean clover stunt virus [SCSV], and nanovirus DNA-R primers [F103 and R101]) (2). All six Azeri samples as well as the reference nanovirus isolates (SCSV-Australia, MDV-Japan, and FBNYV-Syria) generated amplicons of the expected size (~770 bp) using the nanovirus DNA-R primers (F103 & R101). In addition, Azeri samples and FBNYV-Syria yielded a PCR amplicon of the expected size (666 bp) with the FBNYV primer pair. The MDV- and SCSV-specific primers did not generate amplicons with these six samples. Sequence analysis of the FBNYV amplicons from two isolates (AzL 282-07 from lentil [GenBank Accession No. GQ351600] and AzV 277-07 from vetch [GenBank Accession No. GQ371215]) showed that they were 99% identical with each other. Comparing the sequence of AzL 282-07 with that of other nanoviruses revealed identities of 97% (FBNYV-Spain; DQ830990), 96% (FBNYV-Iran; AM493900), 92% (FBNYV-Syria; Y11408), 92% (FBNYV-Egypt; AJ132183), 78% (MDV; AB044387) and 69% (SCSV-Australia; U16734). FBNYV has been reported to infect food legumes in many countries in West Asia and North Africa and cause economic losses on faba bean in Egypt, Jordan, and Syria. To our knowledge, this is the first record of FBNYV infecting legume crops in Azerbaijan. References: (1) A. Franz et al. Ann. Appl. Biol. 128:255, 1996. (2) S. G. Kumari et al. Phytopathol.

Cymothoid isopods are parasitic crustaceans that cause serious impact on marine fish and might lead to fish mortality and consequently, economic losses. Histopathological alterations caused by Anilocra spp. have not been studied well. This study aims to report the histopathological changes caused by Cymothoid, Anilocra leptosoma Bleeker, 1857 in the skin of Bloch's gizzard shad, Nematalosa nasus (Bloch, 1795). Histopathological examination of processed skin tissues showed changes caused by A. leptosoma, such as hyperplasia and erosions of the epidermis associated dermal oedema and muscle degeneration. The host response also included an aggregation of subepithelial dense sheets of hemosiderin-laden macrophages within the dense mixed inflammatory cells. The cymothoid, A. leptosoma are serious parasites of marine fish that can cause severe economic loss in the commercially important fish species. The present study represents the first record of the parasitic cymothoid, A. leptosoma on N. nasus from India.

The leafhopper Poekilloptera phalaenoides L. (Auchenorrhyncha: Flatidae) is a very important species in agriculture because it causes damages and economic losses in agricultural activities. In observing fragments of semi-deciduous forest, riparian forest and cerrado forest (Cerradão) in Jataí, Montividiu and Paraúna in the southwest of the state of Goiás during the month of January 2012, were observed natural populations of Tachigali vulgaris (carvoeiro-branco). In the southwest of Goiás, an important agricultural region of the country, little is known about the damage caused to commercial crops by the leafhopper treated in this work, but here we call attention to the action of an agricultural pest interacting negatively with the native vegetation. The presence of P. phalaenoides in the Cerrado is already known, but the presence of the spittlebug in the southwest of the state of Goiás in T. vulgaris, especially in a situation of damage to the native population of the tree in forest fragments surrounded by agricultural crops. Thus, the objective of this work is to bring this first record of P. phalaenoides in T. vulgaris in the Cerrado of southwestern goiano.

New Pest

The pineapple tarsonemid mite Steneotarsonemus ananas (Tryon), 1898 is associated with pineapple around the world, including Costa Rica. Here, we report its association with Neoregelia sp. (Bromeliaceae) for the first time. These mites damaged the plantlets considerably, affecting the esthetic quality of the product and thus causing economic losses to the local growers. This discovery prompted us to redescribe the adult females and males from the type host and locality (pineapple in Queensland, Australia) and compare it with the original description, subsequent descriptions, and material collected from the USA, Costa Rica, and Colombia on pineapple, Neoregelia, and an unidentified bromeliad. Further specimens from pineapple in Guatemala were identified as the same species and represent the first record for this country. We concur with previous observations that the original description by Tryon is not the same species in subsequent descriptions. We tentatively consider all specimens examined the same as those described as S. ananas in succeeding descriptions, i.e., Steneotarsonemus ananas Tryon sensu Beer.

The brown marmorated stink bug, Halyomorpha halys Stål, 1855 (Hemiptera: Heteroptera: Pentatomidae), is recorded from Slovakia for the first time based on a 5<sup>th</sup> instar larva collected in the town of Štúrovo, Slovakia. The current distribution, economic importance and biology of the species are briefly reviewed. During the visit to Štúrovo, a mass occurrence of adults and larvae of the southern green stink bug, Nezara viridula (Linnaeus, 1758) (Pentatomidae), so far captured in Slovakia in 2014 only as a single specimen, was also observed. This observation confirms the presence of N. viridula as an established species in southern Slovakia. Both species are important pests to a large number of crops (vegetables, fruit trees, decorative plants, etc.) and can cause considerable economic losses.

Xiphias Gladius

Swordfish (Xiphias gladius) is a migratory fish commercially exploited due to high export value. Presence of parasites in fish lead to economic losses in the export market and public health issues. This study was conducted to identify the parasite larvae inhabiting swordfish and to determine its phylogenetic origin using ribosomal subunit gene sequence. Parasite samples were extracted from swordfish muscles and five larvae belong to Molicola genus, confirmed by scolex morphology, were used for genomic DNA extraction. Polymerase chain reaction (PCR) was performed to amplify 18S and 28S ribosomal RNA (rRNA) subunit genes followed by Sanger sequencing. DNA sequences were edited by BioEdit software and assembled by CLC genomics version 8.0. Consensus sequences were aligned with NCBI blast to determine the species status. Isolated larval sequences were best aligned with genus Molicola followed by genus Gymnorhyncha.  Out of the two published Molicola rRNA gene sequences, 99% identity was observed with Molicola sp. HP5 isolate from Indonesia. Due to lack of sequence data on other Molicola species (except M. thyristes) for comparison, our sequences were published as Molicola sp. Sri Lankan isolates. This is the first record of Molicola sp. in swordfish from Sri Lanka and the results will enhance the knowledge on the distribution of Molicola species while contributing to expand the genetic information on rRNA coding sequences.

Mollusc Species

The presence of alien mollusc species in an ecosystem has a negative impact on the endemic mollusc fauna and can result in economic losses. The West African land snail Tomostele musaecola (Morelet) was previously recorded from numerous localities in the Western Hemisphere. In this paper, we provide a new locality of this malacophagous snail in the Dominican Republic. The species is recorded from an urban park named Parque Ecológico Las Caobas in the province of San Cristóbal. In order to update the current distribution of T. musaecola in the Americas we examined the literature and the online database of the Invertebrate Zoology Collection of the Florida Museum of Natural History (FLMNH); when available, citizen science data were also used. A map is provided to illustrate the current distribution of the species in the Americas. The total number of records in the Western Hemisphere is 51, and 26 of them are part of this review. More studies are needed on the interaction of this species with the native land snails. Trade and planting of ornamental species in urban parks facilitate the establishment and expansion of alien molluscs.
