本文总结了大型食品冷库这一特殊场合灭鼠的技术措施。用香油拌半熟花生米碎粒、稻谷、大米进行诱饵选择试验,鼠类摄食香油拌半熟花生米粒显著高于稻谷、大米。在不停产清库的条件下,连续投入2.34%鼠甘伏花生米毒饵3天,同时做好防制等,平均灭鼠率达96.17%。 相似文献

为了研究杀鼠灵毒饵对昆明地区家栖鼠的杀灭效果,作者于1997年在实验室进行了毒杀效果实验。0.025%、0.05%和0.10%三个浓度的杀鼠灵毒饵对家栖鼠平均耗饵量分别为19.2g/只、18.18g/只、12.59g/只,平均每只鼠摄入纯药量分别为4.8mg、9.1mg和12.5mg,毒鼠率均为100%,平均死鼠时间为4.0~5.5天,结果表明杀鼠灵毒饵对昆明地区家栖鼠类具有较好的杀灭作用,仍可作为一种有效的灭鼠剂用于灭鼠。 相似文献

目的构建糖皮质激素受体(glucocorticoid receptor,GR)结合域的诱饵表达载体。方法RT—PCR扩增GR结合域,克隆入pMDl8-T,测序正确后,再亚克隆入诱饵载体pGBKT7中,再把构建好的诱饵载体pGBKT7.GR转化到酵母AHl09细胞中,并用Western blot分析诱饵蛋白的表达情况,同时检测诱饵蛋白的毒性和自激活作用。结果成功扩增了GR结合域,并分别成功克隆到pMDl8-T和pGBKT7中,测序结果正确。诱饵载体成功转化到酵母AHl09细胞中,无毒性和自激活作用,Western blot分析结果也证实了酵母细胞高表达诱饵蛋白。结论成功构建了GR结合域的酵母诱饵表达载体。 相似文献

目的:为寻找杀灭蜚蠊的有效制剂,制备了高效氯氟菊酯毒饵。并进行了实验室和现场杀灭蜚蠊效果的观察。方法:将氯氰菊酯可湿性粉剂与增效剂八氯二丙醚按比例混合,配以红糖、奶粉等赋形剂制成所需颗粒状毒饵。进行适口性及动物毒性试验,并与不加增效剂的毒饵进行实验室和现场的杀灭蜚蠊效果对比观察。结果:适口性试验结果表明,蜚蠊对高效氯氰菊酯毒饵24h消耗量为98mg,对混合饲料24h消耗量为8mng。动物毒性试验结果表明,该毒饵对小白鼠的LD50>10000mg/kg。实验和现场杀灭蜚蠊结果表明,该毒饵具有击倒虫体迅速和高效、低毒的效果。投放毒饵3个月后,虫体仍保持低密度。结论:此毒饵具有高效、速杀和滞留杀灭蜚蠊的效果,完全符合实际应用要求。 相似文献

ObjectiveTo compare the acceptance and efficacy of cereal bait containing different concentrations of poultry egg components in laboratory and poultry farms to control house rat, Rattus rattus (R. rattus).MethodsAcceptance of cereal bait containing different concentrations (2%, 5% and 10%) of poultry egg components such as egg shell powder (ESP), egg albumin (EA) and crushed egg shell as bait additives were studied after exposing them to different groups of rats in bi-choice with bait without additive. Behaviour of rats towards cereal bait containing 2% concentration of different egg components was recorded in no-choice conditions through Food Scale Consumption Monitor. In poultry farm predominantly infested with R. rattus, acceptance and efficacy of 2% zinc phosphide bait containing 2% EA and ESP was evaluated. Trap success of single rat traps containing chapatti pieces smeared with 2% EA and 2% ESP was also evaluated in poultry farm.ResultsIn bi-choice tests, significantly (P<0.05) higher preference was observed for baits containing 2% and 5% ESP and all the three concentrations of EA compared to plain bait by female rats and that of baits containing 5% and 10% EA by male rats. In no-choice test, non-significantly higher consumption, number of bouts made and time spent towards bait containing 2% EA was found by rats of both sexes. In poultry farm, acceptance and efficacy of 2% zinc phosphide bait containing 2% EA and ESP was significantly (P<0.05) more than 2% zinc phosphide bait without additive. No significant difference was, however, found in trap success of single rat traps containing chapatti pieces smeared with 2% concentration of EA and ESP placed in the poultry farm.ConclusionsPresent data support the use of 2% egg albumin and egg shell powder in cereal bait to enhance acceptance and efficacy of 2% zinc phosphide bait against R. rattus. This may further help in checking the spread of rodent borne diseases to animals and humans. 相似文献
