Toxicity of DDT to Japanese quail as influenced by body weight, breeding condition, and sex.

摘要: Abstract Controlled experiments were utilized to simulate the stresses on wild birds of breeding condition and weight loss due migration. Light conditions in laboratory manipulated produce Japanese quail ( Coturnix coturnix japonica ) not condition. Within each these groups, some partially starved before dosage fully fed. Birds then fed dietary levels 0, 700, 922, 1214, or 1600 ppm dry p,p′ -DDT for a period 20 days until death. more susceptible DDT intoxication than nonstarved ones, slightly so Similarly, males died earlier females, lighter strain used second half study heavier first half. The sex only survived longer individuals receiving same treatments, but they also lost greater proportion their During early portion period, females less sensitive males. After 10 dosage, however, cumulative mortality rapidly approached that Food restriction prior strains quail, conditions, sexes resulted differences corresponding accentuation delay effects different DDT.
