A new species of Asphondylia Loew, 1850 (Diptera, Cecidomyiidae) on Hancornia speciosa (Apocynaceae), a native plant to Brazil

ABSTRACT Asphondylia hancorniae, sp. n. (Diptera, Cecidomyiidae) is described and illustrated. This species was collected in Atlantic Forest and Caatinga domains in Bahia State (Northeastern Brazil). It induces galls on fruits of Hancornia speciosa Gomes (Apocynaceae), a plant native to Brazil. Asphondylia hancorniae is compared to other congeneric species which induce galls on Apocynaceae.

Detection of bloodworm larvae (Diptera: Chironomidae) in the golden apple snail Pomacea canaliculata (Lamarck, 1819) (Gastropoda: Ampullariidae) in Metro Manila

Background@#Pomacea canaliculata (Lamarck, 1819) is an invasive freshwater snail in the Philippines that damages crops but is consumed as food. It is known to harbor parasites, some of which are pathogenic to humans. @*Objectives@#The objective of this study is to examine P. canaliculata individuals present in Metro Manila for parasite infection and identify the parasites and other organisms associated with the snail using molecular identification. @*Methodology@#P. canaliculata were collected from rivers and marketplaces in Metro Manila. Individuals were crushed and digested in Ash's digestive fluid and observed under a microscope. Collected parasites were subjected to DNA barcoding of the COI gene for putative identification. @*Results@#A total of 462 snails were gathered from 15 sites, eight of which were market areas that sourced the snails from outside Metro Manila. No known parasites were found. Two snails were found to contain insect larvae in the mantle (0.43% infection). The closest BLAST matches for the two insect larvae were the chironomid fly Nilodorum tainanus (91.0% identity) from a snail in Sucat, Muntinlupa, and another chironomid Parachironomus sp. (92.8% identity) found in a snail originally from Cavite and brought to Calumpang, Marikina. @*Conclusion@#This study is the first report of the presence of chironomids in Philippine P. canaliculata. This could have an impact on the allergenic status of these mollusks if consumed while containing these chironomids. The absence of infection of other medically important parasites is possibly due to the patchy distribution of the snails and few interactions with the definitive hosts of known parasites.

Phenolic substances and cyanogenesis in galled and non-galled tissue of the fern species Microgramma vacciniifolia / Substâncias fenólicas e cianogênese em tecidos galhados e não galhados da samambaia Microgramma vacciniifolia

Galls, neo-formed plant structures that can occur in different organs, are generated by species-specific interaction with an inducing organism. Inducers manipulate the metabolism of its host. Microgramma vacciniifolia (Langsd. & Fisch.) Copel. is a Neotropical epiphytic fern that hosted two stem galls, one induced by a midge species (Diptera) and other by a micromoth species (Lepidoptera). The aim of this study was to evaluate the impact of these two gall-inducing insects on the biochemistry of phenolic acids and the cyanogenesis in galls, stems and leaves of M. vacciniifolia. High performance liquid chromatography (HPLC) indicated a total of 14 phenol derivatives, including caffeic and coumaric acid. Principal Coordinates Analysis (PCoA) of the phenolic substances indicated three groups consisting (1) non-galled stems and micromoth-induced galls; (2) midge-induced galls; (3) midgeinduced galls with parasitoids. Regarding the frequency of cyanogenesis assessed by the picrate paper test, the chi-squared test showed significant difference between fertile leaves (8.3%), sterile leaves (27.7%), non-galled stems (0%) and galls. Among galls, only the midge-induced galls analyzed were cyanogenic (15%). Our results indicated that the different gall-inducers (midge and micromoth) promote species-specific alterations to the phenolic substance composition of the host fern.

O objetivo deste estudo foi avaliar o impacto desses dois insetos indutores de galhas na bioquímica dos ácidos fenólicos e da cianogênese em galhas, caules e folhas de M. vacciniifolia. Em análise de cromatografia líquida de alta eficiência (CLAE) foi possível indicar a presença de um total de 14 derivados fenólicos, incluindo ácido cafeico e ácido cumárico. Análise das Coordenadas Principais (ACoP) indicou três grupos (1) caules não galhados e galhas induzidas pela micromariposa; (2) galhas induzidas pelo mosquito; (3) galhas induzidas pelo mosquito com parasitoides. Em relação a frequência da cianogênese analisada com o teste do papel picrato, o teste do qui-quadrado apresentou diferença significativa entre as folhas férteis (8,3%), folhas estéreis (27,7%), caules não galhados (0%) e galhas. Entre as galhas, somente aquelas induzidas pelo mosquito foram cianogênicas (15%). Os resultados encontrados indicam, ao menos para as substâncias fenólicas, que os insetos indutores de galha (mosquito e micromariposa) promovem alterações espécie-específica na composição química da samambaia hospedeira.

Asphondylia maricensis (Diptera, Cecidomyiidae): pupa description and new combination

ABSTRACT Asphondylia maricensis Maia & Couri, 1992 (Diptera, Cecidomyiidae) was described based on female and larva of third instar. Through fieldworks carried on the type locality, Maricá (RJ, Brazil) and rearing in laboratory, pupal exuvia was obtained and described for the first time. Its morphology indicates that the species belongs to Bruggmanniella Tavares, 1909. Therefore, a new combination is proposed, Bruggmanniella maricensis (Maia & Couri, 1992).

Ecología y diagnóstico de Enallodiplosis discordis(Diptera:Cecidomyiidae): un nuevo defoliador ferozcon repercusiones directas en la pérdida del bosqueseco de Prosopis y los medios de vida en Perú / Ecology and diagnosis of Enallodiplosis discordis (Diptera:Cecidomyiidae): A fierce new defoliator with direct repercussions for loss of Prosopis dry forest and livelihoods in Peru

Resumen Las regiones desérticas costeras del Pacífico de Perú y Chile albergan especies de Prosopis (Leguminosae: Mimosoideae), árboles bien adaptados a las condiciones del desierto y con funciones clave en los ecosistemas de bosques secos. Entre el 2001 y 2017, Prosopis en Perú ha sufrido una extensiva defoliación y muerte regresiva, con la consecuente deforestación y disminución de la producción de vainas de algarrobo. Aquí, se reporta una nueva especie de insecto plaga del bosque de Prosopis en Perú: Enallodiplosis discordis Gagné 1994 (Diptera: Cecidomyiidae), una feroz especie defoliadora que contribuye a la mortalidad generalizada de Prosopis. Se proporciona un análisis de la taxonomía larvaria de E. discordis, ciclo de vida y la infestación ocurrida después de El Niño Oscilación del Sur (ENSO) 1998/99. Su dispersión, distribución y ecología es examinada utilizando distintas líneas de evidencia. Durante casi dos décadas de trabajo de campo, se observó la muerte regresiva del bosque de Prosopis devastando los medios de vida rurales y los servicios de los ecosistemas en las regiones de las tierras bajas del sur (Ica), el centro y el norte de la costa peruana (Lambayeque, La Libertad, Piura). El colapso en la producción de vainas de Prosopis (algarroba, huaranga) y miel también fue registrada. Las notas complementarias proporcionan observaciones sobre: (i) el desarrollo de la plaga y el cambio de uso de la tierra y el clima, (ii) el control biológico y físico de E. discordis, (iii) la polilla Melipotis aff. indomita (Lepidoptera: Noctuidae) como defoliador concurrente de Prosopis.

Abstract The coastal desert of Peru and Chile is home to Prosopis (Leguminosae: Mimosoideae) tree species that are exceptionally well-adapted to the hyperarid conditions and keystone in dry-forest ecosystems. From 2001 to 2018, Prosopis in Peru have suffered widespread defoliation and die-back, with consequent deforestation and collapse in pod production. This paper reports a new insect plague species of Prosopis forest in Peru: Enallodiplosis discordis Gagné 1994 (Diptera: Cecidomyiidae) as a fiercely defoliating agent contributing to widespread Prosopis mortality. An analysis of E. discordis larval taxonomy, life cycle and plague infestation, following El Niño Southern Oscillation (ENSO) 1998/99 is provided. Using distinct lines of evidence, its spread, distribution, and ecology are examined. Over two decades of fieldwork, Prosopis forest die-back and loss was observed devastating rural livelihoods and ecosystem services across lowland regions of southern (Ica), central and northern coastal Peru (Lambayeque, La Libertad, Piura). The collapse in production of Prosopis pods (algarroba, huaranga) and honey was recorded. Supplementary notes provide observations of: (i) plague development, changing land-use and climate, (ii) biological and physical control of E. discordis, (iii) the moth Melipotis aff. indomita (Lepidoptera: Noctuidae) as a concurrent defoliator of Prosopis.

Cell damage induced by polybrominated diphenyl ethers on Chironomus sancticaroli (Diptera: Chironomidae)

Abstract Histological effects of polybrominated diphenyl ethers (PBDEs) were observed in Chironomus sancticaroli larvae which underwent acute exposure. 2,2′,4-triBDE (BDE-17), 2,2′,4,4′-tetraBDE (BDE-47) and 2,2′,4,4′,5-pentaBDE (BDE-99) were evaluated at 0.5, 2.0 and 20 μg L-1. Cytoplasm vacuolisation of oenocytes was observed in the larvae exposed to BDE-17 and BDE-47. Cuénot cells were disrupted at the brush border as an effect of the three evaluated congeners highlighting BDE-47 at 2.0 μg L-1; 60% of larvae displayed this disruption. The midgut showed changes in the morphology of apex cells located next to the lumen of region I exposed to BDE-17 and BDE-47, while BDE-99 induced a narrowing of the lumen diameter. Significant cytoplasm vacuolisation of the larvae exposed to BDE-47 and BDE-99 was observed in region II of the midgut. Salivary glands showed acidophilic granules in the cytoplasm exposed to BDE-17 and BDE-47. The results showed that the tissues of C. sancticaroli were sensitive to flame retardants; these histopathologies can compromise the health and physiology of this organism, highlighting the concern with the presence of PBDEs in freshwater sediments.

Species Diversity and Seasonal Distribution of Culicoides spp. (Diptera: Ceratopogonidae) in Jeju-do, Republic of Korea

Biting midges belonging to the genus Culicoides (Diptera: Ceratopogonidae) were collected by Mosquito Magnet(R) and black light traps at 5 sites on Jeju-do, Republic of Korea (Korea), from May-November 2013 to determine species diversity and seasonal distribution. A total of 4,267 specimens were collected, of which 99.9% were female. The most common species was Culicoides tainanus (91.8%), followed by C. lungchiensis (7.2%) and C. punctatus (0.6%), while the remaining 4 species accounted for <0.5% of all Culicoides spp. that were collected. High numbers of C. tainanus were collected in May, followed by decreasing numbers through August, and then increasing numbers through November when surveillance was terminated. Peak numbers of C. lungchiensis were collected during September, with low numbers collected from May-August and October-November. The presence of C. lungchiensis in Korea was confirmed by morphological and molecular analyses.

Seasonal Abundance of Culicoides (Diptera: Ceratopogonidae) Collected by Mosquito Magnet(R) in Northern Gyeonggi-do (Province), Korea

Biting midges (Culicoides: Ceratopogonidae) were collected by Mosquito Magnet(R) traps at the Neutral Nations Supervisory Commission (NNSC) camp and Daeseongdong village inside the demilitarized zone (DMZ) and near the military demarcation line (MDL) separating North and South Korea and at Warrior Base (US Army training site) and Tongilchon 3 km south of the DMZ in northern Gyeonggi Province, Republic of Korea (ROK), from May-October 2010-2012, to determine their seasonal distributions. A total of 18,647 Culicoides females (18,399; 98.7%) and males (248; 1.3%) comprising 16 species were collected. Overall, the most commonly collected species was Culicoides nipponensis (42.9%), followed by C. erairai (29.2%), C. punctatus (20.3%), C. arakawae (3.3%), C. pallidulus (1.8%), and C. circumscriptus (1.4%), while the remaining 10 species accounted for only 1.1% of all Culicoides spp. collected. The seasonal distribution of C. nipponensis was bimodal, with high numbers collected during May-June and again during September. C. erairai was more frequently collected during June-July, followed by sharply decreased populations from August-October. C. punctatus was collected in low numbers from May-September with high numbers collected during October. C. erairai was predominantly collected from the NNSC camp (85.1% of all C. erairai collected) located adjacent to the MDL at Panmunjeom in the northernmost part of Gyeonggi-do (Province), while other sites yielded low numbers of specimens.

Seasonal Abundance of Biting Midges, Culicoides spp. (Diptera: Ceratopogonidae), Collected at Cowsheds in the Southern Part of the Republic of Korea

Black light traps were used to measure the seasonal and geographical distribution of Culicoides spp. (biting midges or no-see-ums) at 9 cowsheds in the southern half of the Republic of Korea (ROK) from June through October 2010. A total of 25,242 Culicoides females (24,852; 98.5%) and males (390; 1.5%) comprising of 9 species were collected. The most commonly collected species was Culicoides punctatus (73.0%) followed by C. arakawae (25.7%), while the remaining 7 species accounted for <1.0% of all Culicoides spp. collected. The mean number of Culicoides spp. collected per trap night (Trap Index [TI]) was highest for C. punctatus (409.3), followed by C. arakawae (144.2), C. tainanus (4.1), C. oxystoma (1.2), C. circumscriptus (0.7), C. homotomus (0.6), C. erairai (0.4), C. kibunensis (0.3), and C. nipponensis (0.04). Peak TIs were observed for C. punctatus (1,188.7) and C. arakawae (539.0) during July and August, respectively. C. punctatus and C. arakawae have been implicated in the transmission of arboviruses and other pathogens of veterinary importance that adversely impact on animal and bird husbandry.
