Bobwhite quail (Colinus virginianus) received dietary mirex in concentrations of 1, 20 and 40 ppm to investigate reproductive effects of long term exposure to this chemical. Residue analyses of Fo generation breeders indicated that male adipose tissue contained approximately 10 times the mirex level in the diet. Elimination of mirex in females probably was facilitated by egg laying, which reduced mirex buildup in adipose tissue to five times the dietary level. Both sexes were noted to concentrate mirex in fat and breast tissue in direct proportion to the intake of dietary mirex. Eggs collected from Fo generation breeders were not affected deleteriously by mirex as measured by embryo survival to 3 weeks, and thenumber of eggs failing to hatch. Indeed, increased rates of egg fertility and hatchability were associated with higher dietary concentrations. Chick survival data was obtained in Fp and F1 generation hatchlings from hatching through 2 weeks. No chick mortality attributable to pesticide stress was detected in either group of birds. Eggs collected from F1 generation breeders that received 1 ppm were not affected harmfully as measured by embryonation, embryo survival, and hatchability rates. Comparison of residues in wild bobwhites with residues in our experimental findings indicates mirex is apparently not affecting deleteriously reproductive success of wild quail.
为研究长期接触灭蚁灵这种化学物质对繁殖的影响，给雄性白喉鹑（Colinus virginianus）投喂浓度为1、20和40 ppm的灭蚁灵。对F0代繁殖鸟的残留分析表明，雄性脂肪组织中的灭蚁灵含量约为日粮中的10倍。产卵可能促进了雌性体内灭蚁灵的排出，使脂肪组织中灭蚁灵的积累量降至日粮水平的5倍。雌雄两性体内的灭蚁灵均在脂肪和胸肌组织中富集，且与日粮中灭蚁灵的摄入量成正比。通过胚胎存活至3周以及未孵化蛋的数量来衡量，从F0代繁殖鸟收集的蛋未受到灭蚁灵的有害影响。事实上，日粮浓度越高，产蛋受精率和孵化率越高。在F0和F1代雏鸟从孵化到2周龄期间获取了雏鸟存活数据。两组鸟均未检测到因农药应激导致的雏鸟死亡。通过胚胎发育、胚胎存活和孵化率来衡量，从接受1 ppm灭蚁灵的F1代繁殖鸟收集的蛋未受到有害影响。将野生白喉鹑体内的残留量与我们实验结果中的残留量进行比较表明，灭蚁灵显然未对野生鹌鹑的繁殖成功产生有害影响。
