“…Tubifex tubifex is more sensitive to Bayluscide and TFM than are most nontarget aquatic species, and the application rates commonly used to control nuisance species like lampreys, tadpoles, and snails are comparable to those that would be required for oligochaete worm control (Rye and King 1976;Kane and Johnson 1989;Francis-Floyd et al 1997). Bayluscide was more effective at lower concentrations, degraded more rapidly, and is more likely to be approved for this use.…”

“…Several common lampricides are much more toxic to oligochaete worms than to other aquatic organisms (Rye and King 1976). Bayluscide (5,2Ј-dichloro-4Ј-nitrosalicylanilide) has been used to control several invasive and nuisance aquatic organisms.…”

“…Bayluscide (5,2Ј-dichloro-4Ј-nitrosalicylanilide) has been used to control several invasive and nuisance aquatic organisms. It was originally developed as a molluscicide in tropical regions to control the snail host of schistosomiasis and has been used as a synergist with other chemicals to kill sea lampreys Petromyzon marinus in the tributaries of the Great Lakes (Rye and King 1976). Bayluscide has also been used in the Florida aquaculture industry to control the freshwater snail host of the digenetic trematode that is responsible for metacercarial infections in fish (Francis-Floyd et al 1997).…”

“…Applied with metered pumps or as blocks of surfactant mix, it is relatively selective in killing the larval stage of sea lampreys (Rye and King 1976). Several investigations have suggested that TFM could be effective for controlling frog larvae in hatchery ponds (Kane et al 1985;Kane and Johnson 1989).…”

“…The effects of TFM and Bayluscide on nontarget organisms and their impacts on aquatic systems have been studied extensively to support U.S. Environmental Protection Agency registration as restricted-use pesticides. A number of studies have shown that these chemicals have a higher toxicity to oligochaetes than to other benthic macroinvertebrates (Rye and King 1976;Dermott and Spence 1984;Jeffery et al 1986;Kolton et al 1986).…”

Standard 24‐h toxicity tests were performed to determine the acute toxicity of Bayluscide (5,2′‐dichloro‐4′‐nitrosalicylanilide) and 3‐trifluoromethyl‐4‐nitrophenol (TFM) to two strains of the oligochaete worm Tubifex tubifex exposed and unexposed to Myxobolus cerebralis, the causative agent of whirling disease. In addition, microcosm trials were conducted to test the effect of three treatment levels of each chemical on the density of T. tubifex in an earthen hatchery pond. In the toxicity tests, worms that were susceptible to M. cerebralis infection were more sensitive to both chemicals than worms that were resistant to the parasite. The toxicity differences of exposed and unexposed worms within a lineage were not as great as those between lineages. Among worms that were susceptible to M. cerebralis, the concentrations of TFM that were lethal to 50% of the test organisms (LC50s) were 6.3 mg/L for worms that had been exposed to M. cerebralis myxospores and 7.3 mg/L for unexposed worms; for resistant worms, the corresponding LC50s were 8.2 and 7.7 mg/L. Among susceptible worms, the LC50s of Bayluscide were 0.060 mg/L for organisms exposed to M. cerebralis myxospores and 0.062 mg/L for unexposed organisms; resistant worms had LC50s of 0.096 and 0.106 mg/L. In the microcosm trials, Bayluscide treatments reduced worm densities by 73–82%, while the TFM treatments reduced worm densities by 34–88%. Given its rapid degradation, relatively selective toxicity, lower cost, and regulatory status, Bayluscide appears to be the best candidate for further study as a chemical control of the oligochaete host of the parasite that causes whirling disease in salmonid fishes.

Some typical and more frequent freshwater invertebrates of running waters were studied to examine the influence of styrene, xylene and benzene on their mortality. Snails Amphimeluniu holundri FER. and Lymnueu srugnulis L. and crustacenas Asellus uquuticus L. and Gummurus fossurum KOCH., were used in the semi-static test. Compounds were added in volume concentrations of 0.005 to 0.4% v/v. For all concentrations LCB was calculated by probit method, which demonstrated that mortality depends much more on increased concentrations (depending on the initial concentration) than on the length of exposure. Styrene was the most toxic, followed by xylene and then benzene. The species G. fossurum showed marked sensitivity, followed by A. uquuticus, and the species A. hukundri and L. srugnalis showed less sensi tivity .
