Some observations on altered morphology in Amphipsyche meridiana (Hydropsychidae: Trichoptera) larvae from the Pasak Jolasit Dam Outlet, central Thailand
نویسنده
چکیده
Amphipsyche meridiana Ulmer, 1909. larvae from the River Pasak below the Pasak Jolasit Dam were examined for alteration of morphological structure such as the anal papillae, surface, and tracheal gills of the larvae. The tracheal gills were the most altered followed by surface and anal papillae. Factors such as conductivity, and inputs of orthophosphate, sulfate, turbidity, other contaminants, and/or stream profiles may have contributed to the abnormalities.

Larvae of Amphipsyche species (Trichoptera: Hydropsychidae) from Thailand.
Morphological characters and scanning electron microscope images of the larvae of Amphipsyche meridiana and A. gratiosa are given. Pupal identifications are based on genitalic features in common with described adults, and larvae were associated with the pupae based on residual larval sclerites captured in the pupal case. Herein, the final larval instar is described, diagnosed, and photographed ...

Five new species of the genus Cheumatopsyche (Trichoptera: Hydropsychidae) from the Phetchabun Mountains, Thailand, 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 b...
متن کاملSimultaneous measurement of uptake and elimination of cadmium by caddisfly (Trichoptera: Hydropsychidae) larvae using stable isotope tracers.
The use of stable isotopes coupled with inductively coupled plasma-mass spectrometry provides a unique opportunity to investigate pathways of metals in aquatic invertebrates. In this study, the simultaneous uptake and elimination of cadmium (Cd) in stream-dwelling caddisfly (Trichoptera: Hydropsychidae) larvae was measured in laboratory experiments with stable isotopes of Cd. In one experiment,...
