摘要: Red-winged blackbirds (Agelaius phoeniceus) and dickcissels (Spiza americana) inhabiting wheat fields treated with 0.67 kg AI/ha methyl parathion 1.35 toxaphene showed brain cholinesterase (ChE) inhibition compared birds untreated fields. Maximum occurred about five days after insecticide application. ChE activities again approached “normal” 10 treatment. for red-winged differed significantly (p<0.05); maximum the former species was 74%, latter, 40%. These differences could not be explained by diets of two species, as they were similar.
