“…The embryo of the grass shrimp, Palaemonetes pugio, is less sensitive to etofenprox than are the adult and larval life stages (DeLorenzo and De Leon 2010). In contrast, the LC50 overall values from my experiment II were similar to the 48h median effect concentration (EC50) value of 0.116 μg/L for first-instar larvae of C. brevilineata (Yokoyama et al 2009b), which were the most sensitive of the larval instars to several insecticides (Yokoyama et al 2009c). Moreover, my LC50 overall values were comparable to the HC5 value of 0.085 μg/L estimated from a species sensitivity distribution analysis of etofenprox using reliable acute toxicity data in aquatic invertebrates (Nagai 2016), and they were also close to fieldrelevant concentrations: etofenprox has been detected at maximum concentrations from 0.04 to 0.16 μg/L in water samples from rivers and a canal flowing through paddy field areas in Japan (Tanabe and Kawata 2009;Añasco et al 2010).…”

“…They are suited for use in environmental impact assessments because of their high species diversity and their importance in the functioning of aquatic ecosystems (Rosenberg et al ). The impacts of pesticides on larvae of aquatic insects have attracted interest from many ecotoxicological researchers (Peterson et al , ; Beketov and Liess , ; Yokoyama et al , ). Several researchers have performed experiments using the eggs of aquatic insects to clarify the effects of insecticides on embryonic stages.…”

Although the egg of aquatic insects is one of the main life stages that can be exposed to contaminants in water, little is known about the detailed impacts of contaminants on eggs of aquatic insects. The present study aimed to clarify the vulnerable embryonic stages of the caddisfly Cheumatopsyche brevilineata exposed to 2 insecticides, etofenprox and diflubenzuron, which are severely harmful to aquatic insects, and to assess the effects of exposure duration on toxicity of etofenprox to the embryonic stage. Eggs obtained from laboratory culture of the insect were exposed to etofenprox for different periods (2, 4, 6, or 8 d) and at different embryonic stages. In experiments with diflubenzuron, eggs were exposed for 2 d at different embryonic stages. These insecticides did not kill the embryos during exposure, but they inhibited hatching post exposure. Diflubenzuron also induced morphological abnormalities of hatchlings and reduced their survival. The overall median lethal concentration (LC50overall) values varied significantly from 0.0560 to 5.19 μg/L for etofenprox among exposure durations and among embryonic stages, and from 0.442 to 2.89 μg/L for diflubenzuron between embryonic stages. The toxicity of etofenprox to the embryo was more dependent on the embryonic stage at the time of exposure than on the exposure duration. The vulnerable embryonic stage differed between the insecticides. Etofenprox more strongly inhibited hatching of embryos at later stages, whereas sensitivity to diflubenzuron was higher in the following order: stages E3 to E7 > stages E1, E2, and E8. The different responses of C. brevilineata embryos may be attributable to differences in insecticide mode of action and in functional development of insecticide target sites during embryogenesis.

“…Yokoyama et al (2009c) also examined toxicity of fenitrothion, along with fenobucarb and imidacloprid, on larval stages of the caddisfly Cheumatopsyche brevilineata.Based on 48-hour acute toxicity tests using two larval strains, the authors found that first instar larvae were the most sensitive to all pesticides, and the fifth instar stage was least sensitive. Sensitivity also varied between the strains tested for fenitrothion and fenobucarb Gaworecki et al (2009).…”

This review includes works published in the general scientific literature during 2009 on the effects of anthropogenic pollutants on freshwater organisms. It begins with two broad sections: research reviews and broad field studies and surveys. This is followed by reviews of research categorized in sections to reflect the pollutant class. These sections include wastewater, stormwater and non‐point source pollution, nutrients, metals, persistent organic pollutants, pharmaceuticals, endocrine disruptors, pesticides, petroleum hydrocarbons and polycyclic aromatic hydrocarbons (PAHs), ionic liquids, and nanomaterials. The final section includes works describing innovations in the field of freshwater pollution research.

In contrast to aquatic vertebrates, there is scarce available information on the contrasting tolerance to fluoride of different life stages and/or sizes of aquatic invertebrates. The purpose of this study was to assess the likely differences in sensitivity between juveniles and adults of the aquatic snail Potamopyrgus antipodarum (Hydrobiidae, Mollusca) to short-term (4 days) toxicity of fluoride ion (F(-)). LC50 and EC50 values for juveniles were significantly lower than those for adults at 24, 48, 72 and 96 h. Based on our results, the use of fluoride data of bioassays with juveniles should provide more protective water quality criteria than data from adult stage.
