The larvae of caddisfly species (Insecta, Trichoptera) in northern Thai streams and their relationships to environmental variables.

There have been few systematic studies on Trichoptera larvae in Thailand. The larval stages of the endemic species remain mostly unknown. Continued work on describing the larval stages of species will improve the precision of water quality monitoring metrics and enable ecological studies of species.

Nutritional Compositions of Aquatic Insects Living in Rice Fields, with a Particular Focus on Odonate Larvae.

Although the human consumption of aquatic insects is prevalent in many regions, the nutritional composition of the insects has not been comprehensively determined. The proximate composition of sp. was shown to be a good source of protein (49.

The larva of Eubasilissa maclachlani White 1862 (Trichoptera: Phryganeidae) from Thailand, with notes on its biology.

The final-instar larva of Eubasilissa maclachlani White 1862 is described with illustrations for the first time based on Thai specimens. The larva of E. maclachlani exhibits typical morphological characteristics of Phryganeidae.

Description of the final instar larva of Anisocentropus diana Malicky amp; Chantaramongkol 1994 (Trichoptera: Calamoceratidae) in Thailand.

The last instar larval stage of a Southeast Asian species Anisocentropus diana Malicky Chantaramongkol 1994 (Trichoptera: Calamoceratidae) is described and illustrated based on Thai specimens. The larva of A. diana is different from known larvae of the other East Asian species A.

Detection of microplastics in (Penaeidae) and (Palaemonidae) in cultured pond.

Background: The presence of plastic particles in freshwater species is becoming a global concern owing to the potential impact on food security and human health. In this study, we investigated the presence microplastics (MPs) in two economically important freshwater species: the giant freshwater prawn () and the white leg shrimp () cultured in a polyculture pond in the central part of Thailand.

Methods: The gastrointestinal tract (GT) of 300 giant freshwater prawn (160 female and 140 male) and 150 white leg shrimp specimens were investigated for the presence of MPs.

Occurrence of microplastics in edible aquatic insect sp. (Odonata: Libellulidae) from rice fields.

Background: Microplastic (MP) contamination has been discovered in aquatic systems throughout the world. They are well known as contaminants in aquatic species, but there is a gap in understanding about pathways of MP contamination into humans (, through aquatic animals). The goal of this study is to assess MP contamination in an edible aquatic insect ( sp.

The larva and pupa of Potamyia flavata (Banks 1934) (Trichoptera: Hydropsychidae): Description, life cycle, and notes on its biology.

The immature and adult stages of Potamyia flavata Banks 1934 were sampled in seven sampling sites in streams of western Thailand. The samples were collected in February, May, and December 2015 using hand picking. A total of 2,133 individuals of larvae were collected.

Descriptions of larvae of four species of Hydropsyche (Hydropsychidae: Trichoptera) from Thailand.

Morphological characters of the larvae of four species in the genus Hydropsyche (H. dolosa, H. brontes, H.

Larvae of hydromanicus (insecta: trichoptera: hydropsychidae) from Thailand.

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.

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.
