我国农业鼠害发生状况及防控技术进展 总被引:3,自引:0,他引:3
我国的农业鼠害发生十分严重,全国31个省(市、自治区)农区均有发生。每年农田鼠害发生面积2 000~4 000万hm2,造成的粮食损失可占总产量的5%~10%。草原鼠害发生也遍及青海等13个草原大省(自治区),每年草原受灾面积达2 500~4 300万hm2左右,严重危害面积1 500~2 300万hm2。近年,我国农业鼠害防治工作取得了长足进步,成绩斐然。农田鼠害的防治可占到发生面积的50%~80%,农户鼠害的防治数占到发生总数的80%以上。草原鼠害防治面积占严重危害面积的1/3。鼠害监测预警体系的软硬件建设被不断推进。毒饵站技术,抗药性监测等技术措施被用来优化传统化学灭杀法,以减少其环境副作用。不育控制,TBS技术和生态管理等新型可持续鼠害管理技术的研究和试验推广也取得了丰硕成果。指导相关鼠害防治方法实践的国家标准、行业标准及优化策略等陆续推出。综合运用各种技术和方法来控制鼠害的能力得到了很大加强。 相似文献

南疆农区鼠害严重,但基础资料不足。为摸清当地鼠害发生特点,提供有效治理依据,本研究于2018年-2019年在南疆5地州39乡64村开展实地与问卷调查,并采用夹捕法调查害鼠种群构成。结果表明,南疆5地州农村普遍遭受鼠害影响,喀什与和田地区农田受害比例达89.4%,问卷结果表明农户和农田鼠害发生率均大于75%,且西部地区重于东部,约一半受访农户估计每年因鼠害损失超过500元。褐家鼠Rattus norvegicus是农户主要害鼠,占比超过70%;农田则以小家鼠Mus musculus和乌拉尔姬鼠Apodemus uralensis为主。这些结果表明,南疆农区鼠害处于重发态势,褐家鼠是主要鼠害来源,并有外来入侵风险。下一步应聚焦于监测主要害鼠种群动态规律,阐明褐家鼠来源和侵入机制,并探索建立适于当地的害鼠防治模式。 相似文献

草原是我国重要的自然资源,承担着生产、生态和生活等多种功能,在构建生态屏障、促进牧业经济以及维系社会稳定等方面具有重要意义。近几十年来,受全球气候变化和人为过度利用草原的共同影响,我国草原发生大范围退化。草原退化提高了啮齿动物栖息地适合度,促使其种群数量增加,最终导致草原鼠害发生。草原害鼠采食牧草降低草地生产力,掘洞造丘消弱草原固碳、水土保持等生态功能,携带病菌威胁人畜健康。因此,控制草原鼠害事关退化草原治理修复和社会经济的可持续发展。尽管国家开展了一系列草原鼠害研究和工程实践,取得了阶段性成果,但由于草原生态系统的复杂性和社会经济发展需求的不断提升,现有草原鼠害防治成果难以满足草原生态保护与建设的需求,相关理论和技术体系尚未完全形成,学科交叉、技术集成等亟待加强。本文总结了中国草原鼠害发生和防治的现状,并对草原鼠害防治存在的问题进行了讨论,最后从管理和技术层面对加强草原鼠害防治工作进行了展望。 相似文献

BACKGROUND
The shift to more environmentally sensitive agricultural practices over the last several decades has changed farmland landscapes worldwide. Changes including no-till and retaining high biomass mulch has been coincident with an increase in rodent pests in South Africa, India, South America and Europe, indicating a possible conflict between conservation agriculture (CA) and rodent pest management. Research on effects of various crop management practices associated with CA on pest rodent population dynamics is needed to anticipate and develop CA-relevant management strategies.RESULTS
During the Australian 2020–2021 mouse plague, farmers used postharvest stubble management practices, including flattening and/or cutting, to reduce stubble cover in paddocks to lessen habitat suitability for pest house mice. We used this opportunity to assess the effects of both harvest and stubble management on the movement and abundance of mice in paddocks using mouse trapping and radio tracking. We found that most tracked mice remained resident in paddocks throughout harvest, and that mouse population abundance was generally unaffected by stubble management.CONCLUSION
Recent conversions to CA practices have changed how pest house mice use cropped land. Management practices that reduce postharvest habitat complexity do not appear to reduce the attractiveness of paddocks to mice, and further research into new management strategies in addition to toxic bait use is required as part of an integrated pest management approach. © 2023 The Authors.

农田害鼠的种类除与当地的地理环境相适应外,还具有鼠种相对较少,优势种突出,易维持较高数量水平的特征。各鼠种在农田的分布与作物种类有一定的关联度,随着季节变化、作物生长和各种农事活动的干扰,害鼠在作物地之间、或与周围环境之间迁移。随着环境条件的变化,农田鼠类群落不断地进行演替。 相似文献

Eighteen species of rodents are pests in agriculture, horticulture, forestry, animal and human dwellings and rural and urban storage facilities in India. Their habitat, distribution, abundance and economic significance varies in different crops, seasons and geographical regions of the country. Of these, Bandicota bengalensis is the most predominant and widespread pest of agriculture in wet and irrigated soils and has also established in houses and godowns in metropolitan cities like Bombay, Delhi and Calcutta. In dryland agriculture Tatera indica and Meriones hurrianae are the predominant rodent pests. Some species like Rattus meltada, Mus musculus and M. booduga occur in both wet and dry lands. Species like R. nitidus in north-eastern hill region and Gerbillus gleadowi in the Indian desert are important locally. The common commensal pests are Rattus rattus and M. musculus throughout the country including the islands. R. rattus along with squirrels Funambulus palmarum and F. tristriatus are serious pests of plantation crops such as coconut and oil palm in the southern peninsula. F. pennanti is abundant in orchards and gardens in the north and central plains and sub-mountain regions. Analysis of the information available on the damage and economic losses caused by rodents in rice, wheat, sugarcane, maize, pearl millet, sorghum, oil seed, legume and vegetable crop fields, horticulture and forestry, poultry farms, and rural and urban dwellings and storage facilities clearly shows that chronic damage ranging from 2% to 15% persists throughout the country and severe damage, sometimes even up to 100% loss of the field crop, is not rare. Several traditional and modern approaches and methods of rodent control are being used. The existing knowledge of the environmental, cultural, biological, mechanical and chemical methods of rodent control in India is reviewed. Considerable variations exist in the susceptibility of the pest species to different methods, particularly to rodenticides and trapping, their field applicability, efficacy and economics in different crops, seasons and geographical regions, behavioural responses of the pest species to these methods in different ecological conditions and their adoption by farmers in different regions of India. Environmental and cultural techniques, such as clean cultivation, proper soil tillage and crop scheduling, barriers, repellents and proofing which may reduce rodent harbourage, food sources and immigration have long lasting effects but are seldom adopted. However, their significance in relation to normal agricultural practices, intensification and diversification are discussed. Rodenticides, which provide an immediate solution to the rodent problem, form the major component of rodent control strategies in India. Poison baiting of rodents with zinc phosphide and burrow fumigation with aluminium phosphide are common in agricultural fields and recently Racumin (coumatetralyl) and bromadiolone have been introduced for the control of both agricultural and commensal rodent pests in India. Methods and timings of campaigns and successes and problems in implementation of rodent control are also reviewed. 相似文献

The use of poison baits is still the most important control method against commensal as well as field rodents. The baiting techniques used must be adapted to the ecology and behaviour of the target species. The various aspects of rodent behaviour influencing the effect of a control operation are discussed with emphasis on feeding behaviour, exploratory behaviour, neophobia, bait shyness, transporting, hoarding and territoriality. Advantages and disadvantages of sustained versus pulsed baiting techniques are discussed from a behavioural point of view. 相似文献

为确定适于防治南疆农区鼠害的抗凝血类杀鼠剂, 在喀什地区疏勒县采用夹捕法、食饵法、粉迹法评估了杀鼠醚、溴敌隆、溴鼠灵的防治效果, 并采用灌胃法给药测试3种杀鼠剂对家鸡Gallus domestiaus和鸽子Columba livia的安全性。结果表明, 连续投放毒饵10 d后, 与溴敌隆防治区相比, 杀鼠醚防治区的阳性粉块和无毒小麦取食量的下降幅度均无显著差异, 但无毒小麦取食量下降的农户比例更高;且防治后褐家鼠比例更低, 防治期间毒饵消耗量更高。连续单独投放溴敌隆30 d的灭鼠效果可达90.9%, 但10 d溴敌隆与20 d溴鼠灵联合防治防效仅为65.9%。灌胃法测试表明, 对当地家禽类的毒性从低到高依次为杀鼠醚、溴敌隆和溴鼠灵。因此, 建议优选毒性较低的杀鼠醚或溴敌隆用于南疆农区鼠害防治。 相似文献

Because western societies generally see animals as objects of moral concern, demands have been made on the way they are treated, e.g. during animal experimentation. In the case of rodent pests, however, inhumane control methods are often applied. This inconsistency in the human-animal relationship requires clarification. This paper analyses the criteria that must be met when judging the use of animals during experiments, and investigates whether these can be applied in rodent control. This is important, because, until now, animal welfare has been less of an issue in pest control: effectiveness, hygiene and cost efficiency have been leading principles. Two options are available to solve the inconsistency: the first is to abandon the criteria used in animal experimentation; the second is to apply these criteria to both animal experimentation and rodent control. This latter option implies that rodent control methods should not lead to intense pain or discomfort, and any discomfort should have a short duration and should allow escaped rodents to lead a natural life. Adherence to this option will, however, require a shift in the design of rodent control methods: effectiveness will no longer be the leading principle. It will have to share its position with animal welfare and humaneness. 相似文献
