    • 摘要: 为检验施用炔雌醚对农牧交错带长爪沙鼠家群大小与巢域行为的影响,于2006年5月至9月对内蒙古锡林郭勒盟锡林浩特市农牧交错区域分布的长爪沙鼠家群使用炔雌醚进行种群不育控制实验。分设投药区和对照区两个组别,分别于5月、7月与9月份采用1/4样圆面积有效洞口计数法,随机选取24个长爪沙鼠家群,调查对照区域和投药区内沙鼠的家群洞口数量以及家群大小。另在对照区和投药区,随机测定了30个沙鼠的家群活动范围,对比使用炔雌醚前后长爪沙鼠巢域平均半径和活动面积的影响。结果为:对照区家群平均洞口数58个,投药区仅23个,在炔雌醚投药区长爪沙鼠家群受炔雌醚影响,洞口数仅为23个,表明其对长爪沙鼠家群大小控制效果显著。投药区内长爪沙鼠家群密度在投药后连续下降,最大下降幅度较对照区家群密度低70%,表明炔雌醚对长爪沙鼠的家群密度影响较大,可显著降低长爪沙鼠家群密度(P<0.05)。炔雌醚对长爪沙鼠家群平均半径和活动面积的研究结果显示,施用炔雌醚后家群巢域半径与活动面积均显著缩小(P<0.05),与对照区巢域平均面积相比缩小15%、平均活动半径缩小30%。通过以上结果可得出:单独施用炔雌醚对控制野外长爪沙鼠家群以及降低长爪沙鼠巢域、活动面积效果显著。炔雌醚可有效降低农牧交错带长爪沙鼠种群数量和有效活动范围,这对于农牧交错带的鼠害防控,同时降低鼠源性疾病,包括鼠疫的传播都有一定的意义。

    • 摘要: 为探究不同剂量炔雌醚对小鼠器官、激素和肝肠药解酶的影响,分别以0.008 mg/kg、0.04 mg/kg、0.2 mg/kg、1.0 mg/kg和5.0 mg/kg的炔雌醚油溶液连续3d灌胃小鼠,首次给药7d后解剖取材,检测其器官鲜重、雄鼠精子数量、血清中激素浓度、小肠和肝脏中CYP3 A4酶含量的变化.结果 发现:雌鼠肝脏鲜重随剂量增加而增大,5.0 mg/kg组比对照组增大89.7%;雌鼠小肠、肾脏和脾脏出现不同程度变化,但无明显剂量效应;0.2 mg/kg以上剂量炔雌醚导致雌鼠子宫不同程度的水肿;炔雌醚对雌鼠血清中雌二醇和促黄体素浓度无显著影响,仅1.0 mg/kg组雌鼠血清中卵泡生成素浓度较对照组显著升高;1.0 mg/kg和5.0 mg/kg组雌鼠肝脏中CYP3A4酶总含量较对照组分别显著增加59.1%和102.9%.不同剂量炔雌醚对雄鼠肝脏和脾脏鲜重影响显著,5.0mg/kg剂量组肝脏和脾脏鲜重较对照组分别增大23.3%和130%,但小肠和肾脏无明显剂量效应;不同剂量炔雌醚对雄鼠睾丸鲜重无显著影响,附睾仅有5.0 mg/kg组较对照组显著减小;1.0 mg/kg和5.0 mg/kg组的精子密度和精子总数分别较对照组降低43.9%和70.5%;高剂量炔雌醚使血清中促黄体素和睾酮浓度均显著降低;5.0 mg/kg组雄鼠肝脏CYP3A4酶单位组织含量和总含量较对照组分别升高7.1%和30%.总之,炔雌醚对雌雄小鼠的繁殖均有抑制作用,但最低有效剂量不同,雌性有效剂量更低,而雌性肝脏及CYP3A4酶对炔雌醚的反应显著强于雄性,提示雌鼠肝脏对炔雌醚的代谢更快.

    • 摘要: Quinestrol is a kind of synthetic estrogen which has been used as contraceptive on some rodents.To study the effect of quinestrol on the reproduction ability of Mongolia gerbil (Meriones unguriculataus),we conducted field experiments at farming-pastoral transitional zone in Baiyinxile,Inner Mongolia from May to August in 2006.The experimental area was divided into quinestrol baited area and control area.Standard snap-trap method was monthly used to capture the samples in both areas after spraying quinestrol bait in May.Subsequently,samples were dissected to examine the reproductive system and analyze the effect of quinestrol during June to August.The results showed that:(1) the rate of uterus necrosis in quinestrol baited area from June to August were 75.3%,61.5% and 48.7%,respectively,and these were extreme significantly higher than the control area (P <0.01);(2) the pregnant rate in quinestrol baited area was extreme significantly lower compared with the control area (P <0.01);(3) the litter size in quinestrol baited area was significantly lower than the control area (P < 0.05).These results suggested that quinestrol had a significant suppression effects on the population reproductivity of M.unguriculataus.%炔雌醚对一些鼠类种群具有良好的控制效果.为探究炔雌醚对长爪沙鼠Meriones unguriculataus种群繁殖的影响,于2006年5-8月在内蒙古锡林郭勒盟白音锡勒牧场农牧交错带展开了炔雌醚对长爪沙鼠野生种群繁殖的控制实验.设置了投药区和对照区,5月初进行投药,实验期间采用夹线调查法逐月对样地内的长爪沙鼠进行系统的取样调查,分析炔雌醚对长爪沙鼠种群繁殖的影响.结果显示:在投药之后的6-8月,投药区成体鼠的子宫坏死率分别为75.3%、61.5%和48.7%,与对照区差异有高度统计学意义(P<0.01);投药区成体鼠的怀孕率下降,与对照区差异有高度统计学意义(P<0.01);投药区的胎仔数显著低于对照区(P<0.05).综上表明,炔雌醚对农牧交错带长爪沙鼠种群繁殖的控制具有良好的效果.

    • 摘要: Contraception control is a new method to control rodent pest.Due to the complex relation between rodent population and other populations,when contraception control was implemented to rodent, the dynamical behavior of rodent population and other related populations would alter.A prey-predator model was formulated and analyzed to investigate the effect of contraception control on population dynamics of rodent and its prey.In the model,rodent was predator and was controlled with sterilant.The stability of equilibriums and Hopf bifurcation phenomenon were analyzed by means of Hurwitz criterion,Lasalle invariance principle,center manifold theorem,formal series method and Hopf bifurcation theory.Sometimes,along with the increasing of contraception rate,the amount of rodent will decrease linearly and the amount of prey would rise linearly.Sometimes, the contraception control may result in the amount of rodent and its prey varying periodically in a large extent and the result was awful.Therefore,before implementing the contraception control,understanding the relation of rodent and its prey fully and selecting a suitable contraception rate were necessary.%不育控制是害鼠治理的一种方法.害鼠种群与其他种群有着各种各样的联系,当害鼠种群在不育控制下改变其动力学行为时,与其相关的种群也随着改变其行为.建立了食饵-捕食者模型,其中害鼠是捕食者,对其进行不育控制.利用Hurwitz判据、中心流型定理、形式级数法、Hopf分支理论等分析了模型平衡点的稳定性和Hopf分支现象.有时,随着不育率增加,害鼠数量线性减少,其食饵数量线性增加;有时,不育控制会使害鼠及其食饵数量大幅度周期变化.因此,进行不育控制前,要对害鼠及其食饵有充分的了解,选择适当的不育率.

    • 摘要: 不育控制既可直接降低害鼠种群的生育率,又能影响个体的社会行为,引起种群内等级关系和社群结构的变化,进而干扰种群繁殖.为探究不同剂量卡麦角林对雄鼠行为的影响和持效时间,选取健康雄性黄毛鼠使用50 μg/kg和100 μg/kg卡麦角林灌胃给药,并于给药后第1d和第18 d与正常雄鼠遭遇,第4d和第21 d与正常雌鼠遭遇,比较给药前(卡麦角林灌胃前4d和前1d时分别与正常雄鼠和雌鼠遭遇)和给药后个体行为的差异.结果显示:卡麦角林降低了雄鼠对正常雄鼠的探究、攻击时间,降低雄鼠对正常雌鼠的攻击时间和频次;100 μg/kg卡麦角林降低雄鼠对正常雌鼠的探究频次,且雄鼠自身修饰和休息频次显著减少.这表明卡麦角林可干扰黄毛鼠对同性和异性个体间的社会行为.此外,药物处理后第18d和第21 d,雄性个体与同性和异性个体的社会行为与处理前无显著差异,表明停药后药物对行为的影响会随着时间的延长逐渐消失.%Fertility control reduces the birth rate of rodent populations and influences animal reproductive capability.By contrast,the effects of sterilants on individual behaviors may affect the social hierarchy of populations,and interfere with reproduction in normal animals.To understand the effects of cabergoline treatment dosage and treatment duration on the behavior of male Rattus losea,40 male rats were randomly divided into five groups and treated with 0,50,and 100 μg/kg cabergoline for 3 consecutive days.One male subject from the pre-treatment group (T750,T7100) was assigned to dyadic encounters with one subject from the control group (C) on the first day after the end of the three-day treatment.T2450 and T24100 rats encountered the same rat from C on the 18th day after the end of the three-day treatment.T750and T7100 were assigned to dyadic encounters with normal females on the fourth day after the end of the three-day treatment.T2450 and T24100 rats encountered normal females on the 21st day after the end of the three-day treatment.Social behaviors between the same sex and the opposite sex were observed for 30 min and videotaped.The results showed that cabergoline treatment negatively affected the investigative and aggressive behavior of male R.losea,and reduced the aggression duration and frequency of males toward females.The frequency of investigation,grooming and resting in males that encountered female counterparts were significantly different between pre-and post-treatment with 100 μμg/kg cabergoline.In conclusion,cabergoline treatment disturbs the inter-or intra-sexual social behaviors of R.losea.Furthermore,with longer duration post-treatment,the behavioral data in our experiment were not significantly different compared with pre-treatment.These results indicate that the effects of drug on social behavior of the male can gradually disappear after suspending cabergoline treatment.

    • 摘要: 炔雌醚是一种激素类新型鼠类不育剂,已有研究表明,炔雌醚对某些鼠类种群繁殖具有良好的控制成效.为检验新型不育剂对长爪沙鼠种群的控制效果,2006年5月在内蒙古锡林郭勒盟锡林浩特市农牧交错带开展了炔雌醚对野外长爪沙鼠种群的控制实验,本次实验设投药区和对照区2个组别,5-8月开展逐月的夹线调查以及四分之一圆洞口计数法,对样地内长爪沙鼠进行系统的追踪调查,分析炔雌醚对长爪沙鼠种群数量以及种群性比的作用.结果显示:投药1个月之后,投药区雌鼠比例(16.3%)不及对照组雌鼠比例(51.9%)的三分之一,投药区的雌鼠比例(16.3%)仅为雄鼠比例(83.7%)的五分之一;与对照区相比,投药区长爪沙鼠的密度下降达60%以上.这表明:炔雌醚对野外长爪沙鼠种群的不育控制具有良好效果,且炔雌醚对长爪沙鼠的种群性比影响很大,过量投放炔雌醚可造成雌鼠死亡,单独使用炔雌醚可降低野外不育剂的药物成本.
