“…Eight individual 4-week old shrimps were introduced into a glass beaker filled with 100-ml water samples of 22 ± 1°C. The rearing methods of freshwater shrimp P. compressa improvisa and test methods were described elsewhere (Hatakeyama and Sugaya, 1989;Hatakeyama et al, 1991a,b). The shrimp test was usually conducted on Monday with three replicates per water sample on the four water samples (St. 5 and 9, Tuesday and Friday).…”

“…Biomonitoring using a shrimp mortality test with river water samples is efficient, because the method is simple, the mortality of the control is negligible, and the shrimp-rearing method is easy and stable (Hatakeyama and Sugaya, 1989).…”

“…4) In some aquatic insects, such as blackfly and caddisfly, sensitivities to several organophosphate insecticides decreased with larval growth; [5][6][7] however, the tendency for sensitivity to decrease with growth is not observed in all organisms. [8][9][10][11] In the freshwater shrimp Paratya compressa improvisa, sensitivity to an organophosphate, fenitrothion, did not change until 60 days after hatching. 8) The earliest age class of the amphipod Hyalella azteca was most insensitive to an organophosphate, diazinon.…”

Sensitivity difference to insecticides of a riverine caddisfly, Cheumatopsyche brevilineata (Trichoptera: Hydropsychidae), depending on the larval stages and strains

To determine sensitivity to fenitrothion (MEP), fenobucarb (BPMC) and imidacloprid (IMI) in each larval instar of Cheumatopsyche brevilineata, we carried out 48-hr acute toxicity tests using strains M and K originating from an urban river and an irrigation canal, respectively. First instar was the most sensitive stage to all three insecticides whereas fifth instar was the most insensitive in both strains. Larvae of strain K were significantly more insensitive to MEP through larval growth and to BPMC in second or later instars than larvae of strain M; however, sensitivity to IMI did not differ significantly between strains.

Abstract-Seasonal changes in toxicity of Kokai River water to a freshwater shrimp (Paratya compressa improvisa) were monitored from 1989 to 1993. A 4-d toxicity test was conducted three times a week from April to August from 1989 to 1993 to measure mortality. Seventeen pesticides were analyzed during the biological monitoring. Expected shrimp mortalities were calculated by adding mortalities caused by each insecticide at the measured concentrations. Shrimp mortalities increased in late May to mid-June and could be attributed to additive effects of insecticides such as pyridaphenthion, malathion, and fenobucarb. Mortalities decreased toward the end of June but increased again from July to mid-August and could be attributed to insecticides such as diazinon or fenobucarb, which drifted directly into the river after aerial pesticide spraying on paddy fields. High mortalities decreased rapidly after heavy rains in August.
