Ns. Tietze et al., ACUTE EFFECTS OF PERMANONE(R)-31-66 (PERMETHRIN-PIPERONYL BUTOXIDE) ON NONTARGET MINNOWS AND GRASS SHRIMP, Journal of the American Mosquito Control Association, 11(4), 1995, pp. 476-479
Immature sheepshead minnows (Cyprinodon variegatus), inland silverside
s (Menidia beryllina), mosquitofish (Gambusia holbrooki), and grass sh
rimp (Palaemonetes pugio) were exposed to the mosquito adulticide, Per
manone(R) 31-66, in a series of static toxicity tests conducted in the
laboratory. At 24 h, in order of decreasing susceptibility, LC(50) va
lues were 0.843, 4.07, 5.46, and 6.04 ppb for grass shrimp, inland sil
verside, sheepshead minnow, and mosquitofish, respectively. Forty-eigh
t-hour LC(50) values for grass shrimp, inland silverside, sheepshead m
innow, and mosquitofish were 0.049, 2.86, 3.02, and 4.29 ppb, respecti
vely.
