  • The influence of initial colonization by hydropsychid caddisfly larvae on the development of stream invertebrate assemblages
    Hydrobiologia, 2001
    Co-Authors: Bradley J Cardinale, Christopher M. Smith, Margaret A. Palmer
    Abstract:

    Many aspects of the colonization history of a disturbed site can influence the development of a biological community. Initial colonization is known to play a significant role in community development because of the facilitative or inhibitory effects that `pioneer' species can have on subsequently arriving taxa. We performed an experiment to assess how initial colonization by two species of benthic invertebrates (Trichoptera: Hydropsychidae) might influence the development of stream faunal assemblages. Substrate baskets initially colonized by either Hydropsyche depravata or Ceratopsyche bronta were placed alongside control baskets in a recently flooded stream. After baskets had colonized for 30 days, we found that species composition in treatment baskets was identical to that in control baskets, indicating that the caddisfly taxa had no selective effects on colonization of other macroinvertebrate species. We did, however, find that C. bronta facilitated the recruitment of all species in the colonist pool leading to greater overall abundance and biomass of macroinvertebrates in the final assemblages. In contrast, H. depravata had no effect on the abundance or biomass of colonizing invertebrates. The differential effects of these two taxa on abundance and biomass may have been related to differences in microhabitat complexity created by the construction of their retreats and catchnets. The results of this study support the growing recognition that colonization history does influence the structure of lotic communities, but they also suggest that even closely related taxa can play different roles as initial colonists in community development.

  • characterization of hydropsyche slossonae trichoptera Hydropsychidae capture net polypeptides
    Canadian Entomologist, 2000
    Co-Authors: Louis Tessier, J. L. Boisvert, L. B.m. Vought, J. O. Lacoursière
    Abstract:

    A laboratory study on the sublethal effects of malathion on the net-spinning behavior of the caddisfly larvae Hydropsyche slossonae was conducted in order to assess the potential of net anomalies as an indicator of chronic exposure to organophosphorus insecticides. Two anomalies were identified after chronic exposure to 0.01, 0.05, 0.1, 0.5 and 1.0 μg l−1 malathion. The first was a distortion of the midline meshes where the normal diamond shape structure was disrupted and the meshes were separated by extra strands (called ‘midline’ anomaly). The second aberration observed was a significant decrease in net symmetry. Both anomalies were highly correlated to the toxic action of malathion, i.e. inhibition of the acetylcholinesterase enzyme (AChE). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analyses of capture nets did not show any modification of silk polypeptides after exposure to malathion, indicating that net distortions were not related to silk composition. Both anomalies seem to represent the symptoms of the specific toxic action of malathion; nevertheless, they can serve as an index of the physiological condition of the larvae, especially the midline anomaly. The symmetry of the nets decreased significantly after exposure to 0.5 and 1.0 μg l−1. However, the toxicity curves (EC50) showed that the sensitivity threshold for the midline anomaly ranged from 0.11 to 0.28 μg l−1, which reflect more realistic exposure to concentrations expected to occur in the field. Hence, the use of capture net anomalies of hydropsychid larvae could represent a valuable indicator of sublethal toxicity induced by malathion and other organophosphorus insecticides in running waters.

  • Characterization of Hydropsyche slossonae (Trichoptera: Hydropsychidae) capture net polypeptides
    Canadian Entomologist, 2000
    Co-Authors: LH Tessier, J. L. Boisvert, L. B.m. Vought, J. O. Lacoursière
    Abstract:

    The aim of this study was to characterize polypeptide components of the capture net spun by trichopteran larvae Hydropsyche slossonae (Banks) (Trichoptera: Hydropsychidae). Thirty-one polypeptide bands were identified by SDS – polyacrylamide gel electrophoresis (SDS–PAGE) from extracted net material, with molecular weights ranging from 8500 to 179 000. Comparison with published data on Bombyx mori (L.) (Lepidoptera: Bombycidae) silk, treated under similar denaturing conditions, shows that six low molecular weight polypeptides ranging between 8500 and 18 800 in the silk of H . slossonae are absent from that of B . mori ; furthermore, two high molecular weight polypeptides (210 000 and 220 000) detected in the silk of B . mori are not present in that of H . slossonae . Differences between both groups are probably related to their mode of living and to the specific use of silk (in air versus under water). Our findings are consistent with the current trend in the literature that silk spun by aquatic and terrestrial insects, as well as those spun by different species, is apparently made of different biopolymers according to the protein constituents. Hence, the polypeptide characterization of silk, combined with sequence data and (or) antibodies cross-reactivity data, could represent a potential tool for taxonomic classification improvement of aquatic insects. These results could eventually be used to characterize hydropsychid capture net anomalies induced by environmental pollution. Le but de cette étude était de caractériser la nature des polypeptides présents dans la soie des filets de capture tissés par les larves d’ Hydropsyche slossonae (Banks) (Trichoptera : Hydropsychidae). Trente et un polypeptides ont été identifiés suite à une extraction du matériel contenu dans les filets de capture par la technique d’électrophorèse sur gel d’acrylamide (SDS–PAGE), les poids moléculaires de ceux-ci variant entre 8500 et 179 000. Une comparaison avec des données publiées sur la soie de Bombyx mori (L.) (Lepidoptera : Bombycidae), dans des conditions d’extraction similaires, a révélé que six polypeptides de faible poids moléculaire, variant entre 8500 et 18 800, présents dans la soie d’ H . slossonae étaient absents au niveau de la soie de B . mori . De plus deux polypeptides de haut poids moléculaire (210 000 et 220 000) mis en évidence dans la soie de B . mori n’étaient pas présents au niveau de la soie d’ H . slossonae . Ces divergences entre les deux groupes taxonomiques sont possiblement reliées aux différences notables entre leur mode de vie et leur utilisation spécifique de la soie (dans l’air et dans l’eau). Nos résultats confirment la tendance actuelle dans la littérature où il appert que la soie produite par les insectes aquatiques et terrestres, ainsi que celle tissée par différentes espèces, n’est apparemment pas constituée de biopolymères similaires, et ce à l’égard des analyses poly-peptidiques. Ainsi, l’établissement des patrons polypeptidiques au niveau de la soie, combiné à des analyses de séquence et (ou) des analyses de réaction croisée à l’aide d’anticorps, pourrait s’avérer un outil d’une grande utilité afin d’améliorer la classification taxonomique des insectes aquatiques. Ces résultats seront éventuellement utilisés afin de caractériser les anomalies observables sur les filets de capture des larves d’ Hydropsyche spp. suite à une pollution environnementale chronique.

  • Population Dynamics and Seasonal Occurrence of Adult Amphipsyche meridiana Ulmer 1902 (Trichoptera: Hydropsychidae) in an Irrigation Pond Outlet
    Zoosymposia, 2019
    Co-Authors: Taengon Prommi
    Abstract:

    Population dynamics and seasonal occurrence of adult Amphipsyche meridiana Ulmer, 1902 (Trichoptera: Hydropsychidae) in an irrigation pond outlet at Kasetsart University, Kamphaeng Saen Campus, Nakhon Pathom Province were determined, with the influence of air temperature, wind speed, precipitation and relative humidity on its population density being evaluated. Samples were collected monthly from January to December 2013 by light trapping. Monthly sampling records for adults collected were 24876, 2605, 29344, 43632, 18684, 16524, 29871, 15183, 10548, 17100, 7695 and 15678, respectively. An increase in the number of adults collected was observed from January to July with peaks of 43,632 (18.83%) in April. A remarkable decrease in the number of insects collected was observed in the months after August. There was an increase in the number of adults most influenced by the decrease in precipitation and relative humidity.

  • Distribution of Hydropsychidae (Insecta, Trichoptera) and water quality parameters in Mae Tao Creek, Mae Sot District, Tak Province, northern Thailand
    Zoosymposia, 2016
    Co-Authors: Taengon Prommi, Pronthip Peumwarunyoo, Pharawee Mansukphol
    Abstract:

    The distribution of adult Hydropsychidae and physicochemical variables at Mae Tao Creek, Mae Sot District, Tak Province, northern Thailand, were sampled bi-monthly from February to December 2011. Five sampling sites were selected along the creek. Water temperature, dissolved oxygen, turbidity, sulfate, nitrate-nitrogen, and orthophosphate did not vary significantly during the research period, and pH, electrical conductivity, turbidity, and sulfate did not vary significantly among the sampling sites. A total of 1,065 male individuals were caught belonging to 5 genera and 20 species. Cheumatopsyche carmentis Malicky & Chantaramongkol 1997, Cheumatopsyche dhanikari Malicky 1979, Cheumatopsyche globosa Ulmer 1910, Cheumatopsyche lucida Ulmer 1907 and Potamyia flavata Banks 1934 were identified as the most common species of the research area. Pearson’s correlations were used to determine the relationships between water quality variables and the adult caddisfly faunas. Air temperature, turbidity, nitrate-nitrogen, and ammonia-nitrogen were strongly correlated only with the presence of adult caddisflies.

  • larvae of hydromanicus insecta trichoptera Hydropsychidae from thailand
    Zootaxa, 2015
    Co-Authors: Taengon Prommi, Surakrai Permkam
    Abstract:

    Larvae of only 2 of the 13 species of Hydromanicus known from Thailand have been described previously. In this research, the “metamorphotype method” was used to associate yet-unidentifiable larvae and pupae with their identifiable adults: Pupal identifications were based on genitalic features in common with described adults, and larvae were associated with the pupae. Herein, the final larval instar of Hydromanicus malayanus , H. abiud and H. inferior are described and illustrated.

  • Phylogeny of Macronematinae (Trichoptera: Hydropsychidae) based on molecular and morphological analyses
    Canadian Entomologist, 2019
    Co-Authors: Christine Jewel C. Uy, Ji Hyoun Kang, John C Morse
    Abstract:

    AbstractThe phylogenetic relationships among the members of Macronematinae (Trichoptera: Hydropsychidae) have long been debated and often revised. Our study based on a large subunit (28S) nuclear ribosomal DNA (D2 expansion fragment; 464 base pairs) of gene sequences found all genera to be monophyletic except for the genus Polymorphanisus Walker, which produced two clades in accordance with its species groups established using morphological characters. Phylogenetic reconstruction based on mitochondrial cytochrome oxidase I (658 base pairs) found the same monophyletic relationships, however, except for the genera Polymorphanisus and Macrostemum Kolenati. The placement of the genus Leptonema Guérin-Méneville as the basal clade in the subfamily was also ruled out, which is consistent with previous morphological findings. The monophyly of two previously recognised tribes (Macronematini and Polymorphanisini) was not supported. We also found that the genera Centromacronema Ulmer, Baliomorpha Neboiss, and Macronema Pictet are most closely related, having three head setal warts on the vertex of the head and unsegmented inferior appendages of male genitalia as their synapomorphies. Our study supported the hypothesis of close relationship of the genera Amphipsyche McLachlan and Protomacronema Ulmer with the morphological synapomorphies: absence of a forewing discoidal cell and the presence of elevated head carinae on the larvae. Some notable evolutionary novelties in the structure of adults in various lineages of this subfamily include reduction of maxillae and labium, reduction and loss of a discoidal cell and evolution of a c-sc crossvein in each forewing, fusion of segments in each male inferior appendage, and evolution of dark colour patterns in the forewings. Also, the head setal warts, which are unique organs in Trichoptera, evolved towards a decreasing number in the subfamily. This first molecular phylogenetic study, covering most genera in Macronematinae and including an interpretation of 12 key evolutionary novelties, provides an important basis for resolving long-standing questions regarding phylogenetic relationships and classification of genera and species and helps lay a stronger foundation for inference of testable hypotheses about functional traits for species of this common and widespread subfamily.

  • five new species of the genus cheumatopsyche trichoptera Hydropsychidae from the phetchabun mountains thailand
    Zootaxa, 2013
    Co-Authors: Kitiya Thawarorit, Narumon Sangpradub, John C Morse
    Abstract:

    Five new species of the genus Cheumatopsyche (Trichoptera: Hydropsychidae) from the Phetchabun Mountains, Thai-land, are described and illustrated. The national parks and wildlife sanctuaries in the Phetchabun Mountains are recognized as areas with a high density of endemic species deserving protection. Four new species of Cheumatopsyche ( C . recta , C . diversa , C . triangula , and C . tongto ) have been found in Phu Khieo Wildlife Sanctuary, Phu Kradueng National Park and Thung Salaeng Luang National Park; a fifth new species ( C . cava ) has been found in Phu Kradueng National Park. De-scribing hydropsychid species is important not only to study diversity and distribution but also to facilitate eventual de-scriptions of larvae for use in freshwater biomonitoring programs to detect pollution.

  • diversity of mitochondrial and larval morphology characters in the genus diplectrona trichoptera Hydropsychidae in the eastern united states
    Terrestrial Arthropod Reviews, 2012
    Co-Authors: Lauren E Harvey, Christy J Geraci, John C Morse, Jason L Robinson, Karl M Kjer, Xin Zhou
    Abstract:

    Larvae of species in the caddisfly genus Diplectrona (Trichoptera: Hydropsychidae) are morphologically variable and found in a variety of different lotic habitats across eastern N. America. DNA sequencing of a 658-base pair region of the mitochondrial cytochrome oxidase c subunit I gene revealed 7 haplotype groups within the genus Diplectrona: Four with larvae similar to Diplectrona modesta Banks, two with larvae similar to D. metaqui Ross, and one that is a putative match to D. marianae Reeves. These results provide initial evidence supporting the need for a revision of the genus Diplectrona in N. America, and also possibly for the existence of cryptic diversity within currently recognized Diplectrona species. We discuss these results within the context of the intersection of bioassessment, molecular and morphological taxonomy, and the International Code of Zoological Nomenclature. © Koninklijke Brill NV, Leiden, 2012

  • defining the genus hydropsyche trichoptera Hydropsychidae based on dna and morphological evidence
    Journal of The North American Benthological Society, 2010
    Co-Authors: Christy J Geraci, John C Morse, Xin Zhou, Karl M Kjer
    Abstract:

    In this paper, we review the history of Hydropsychinae genus-level classification and nomenclature and present new molecular evidence from mitochondrial cytochrome c oxidase subunit I (COI) and nuclear large subunit ribosomal ribonucleic acid (28S) markers supporting the monophyly of the genus Hydropsyche. Both molecular and morphological characters support a broad conservative definition of Hydropsyche. Caledopsyche, Hydatomanicus, and Occutanspsyche are synonymized with Hydropsyche. The following species groups are established: Hydropsyche bronta Group (generally corresponding with Ceratopsyche and Hydropsyche morosa and newae Groups), Hydropsyche colonica Group (generally corresponding with Orthopsyche), Hydropsyche instabilis Group (generally corresponding with Hydropsyche s.s.), and Hydropsyche naumanni Group (generally corresponding with Occutanspsyche). Molecular data recovered Hydromanicus as paraphyletic, and Cheumatopsyche and Potamyia as sister taxa. The genus names Plectropsyche and Streptopsyche are reinstated.

  • new species of cheumatopsyche trichoptera Hydropsychidae from north sulawesi indonesia
    Pan-pacific Entomologist, 2008
    Co-Authors: Christy J Geraci, John C Morse
    Abstract:

    Sulawesi Island has a high density of endemic animal species, including insects in the order Trichoptera. We describe the males of four new species of Cheumatopsyche (Trichoptera: Hydropsychidae) from North Sulawesi (Provinsi Sulawesi Utara), and provide a checklist of the Cheumatopsyche species from the Indonesian archipelago. Describing the aquatic insect fauna is an important step toward establishing biomonitoring protocols in Indonesia, which is experiencing rapid development and water pollution problems.
