1983年我站首次在全县开展牛皮蝇病防治工作(文见本刊1983年第6期)。1984年3月、5月两次调查了牛皮蝇第3期幼虫感染率及感染强度(文见本刊1985年第5期)。1985年我们又对牛皮蝇防治效益,进行了调查,结果如下: 一、皮张虻害调查:1983年防治牛皮蝇病前,在河卡采购站对收购冬宰牦牛皮100张进行调查,虻害37张,虻害率37％,无虻害数63张,无虻害率63％;经过连续两年应用倍硫磷防治后,于1985年仍在河 相似文献

蚕蛆蝇是我国主要蚕业害虫之一,近年来由于多种原因,蝇害损失有所增加。1973年在华南农学院赵善欢教授的指导下,应用辐射不育技术引致蚕蛆蝇不育,释放不育蝇,降低田间蝇口密度,以期达到防治的效果。经过三年的田间试验,初步验证辐射不 相似文献

<正> 蝇蛆病,是一种多化性寄生蝇的幼虫(蛆)寄生蚕体而引起的。蚕蛆蝇为害家蚕时期很长,范围甚广,一般从5～11月几乎每个蚕期都有危害,从国内看各个蚕区(除新疆外)皆有发生。据过去调查个别蚕区受蝇害的高达25％以上,自1963年“灭蚕蝇”药物问世以后,蝇害得到基本控制。近年来,我省对本病为害的严重性估计不足,综合防治措施不够有力,加之对生产责任制改变后的养蚕特点认识不够,以致蝇蛆 相似文献

1982年省畜牧兽医总站在西宁皮革制件厂对虻害做了调查,每张牛革损失面积达0.16平方米,折合当时2级绒面革价为3.11元。为了把皮革工业搞上去,发挥我省的经济优势,从1982年秋,对青海牛皮蝇病由局部防治开始,到1984年秋进行全 相似文献

1982—1984年海晏县用倍硫磷连续防治牛皮蝇病三年,取得了满意的效果。1985年全省牛皮蝇病防治技术咨询会议确定;海晏县停止防治一年。1986年根据全省第二次咨询会议的精神,海晏县仅对1—3岁幼年牛进行了防治,以探讨牛皮蝇病新的防治方法。现将海晏县历年对牛皮蝇 相似文献

害获灭 (Ivomec)是美国默沙东药厂于 80年代初推出的一种新型的防治家畜寄生虫药物 ,其有效成份是伊维菌素 (Ivermectin)早在国外已多次证明对危害家畜的多种内外寄生虫有着良好的驱杀效果。本次试验的目的是探讨害获灭药物对寄生于牛的皮蝇科的幼虫的杀灭效果。皮蜱科的两种皮蝇 (牛皮蝇和纹皮蝇 )在我区有着程度不同的分布 ,特别我市邵伯、昭关、绿洋、中闸、嘶马、张纲、双沟等沿长江和沿大运河、邵伯河、荇丝河有草滩地区 ,农民习惯放牧地区有着程度不同的分布。所以我们选择了流行广、感染率高、危害严重的邵伯镇作为试点。经鉴定该镇… 相似文献

Field trials were carried out from 1980 to 1984 on the use of a controlled-release pesticidal fly control technique on farms in Sussex, England, with a recurrent infectious keratoconjunctivitis problem related to fly attack. Pesticide impregnated p.v.c. ear-tags provided control of biting and disease-carrying fly species throughout the season. Over 90% control of flies, compared with untreated herds, was attained using 2 tags impregnated with cypermethrin, fenvalerate or flucythrinate, although control using a single tag was unsatisfactory. In all cases infectious keratoconjunctivitis was almost completely eliminated. 相似文献

THE OVIPOSITIONAL RESPONSE OF THE AUSTRALIAN SHEEP BLOWFLY, LUCILIA CUPRINA, TO FLEECE-ROT ODOURS 总被引：1，自引：0，他引：1
SUMMARY The ovipositional response of Lucilia cuprina flies to odours emanating from fleece-rot lesions of greasy wool in which Pseudomonas aeruginosa bacteria proliferated, was studied. Fractionation of the fleece-rot odours was carried out by bubbling the volatile components through hydrochloric acid and sodium hydroxide solutions to remove basic odours and acidic odours respectively. It was found that the acidic/neutral odours of fleecerot wool, when perfused into wet, greasy wool, stimulated L. cuprina to oviposit. On the other hand, the basic/neutral odours of fleece-rot wool were virtually unattractive to the gravid fly. Similarly, the acidic/neutral odours emanating from fleece-rot lesions of clean wool from which the non-fibre components, wax, suint and epithelial debris, had been removed by scouring, were found to be unattractive to the gravid fly in choice tests. 相似文献

From July 1989 to June 1990, 555 heads of adult sheep obtained from Pamiers slaughterhouse (southwest France) were examined for infestation by Oestrus ovis. Infestation was present in 65% of the heads and the mean larval burden per positive case over the year was 24.8. The monthly prevalence rate varied from 44% in April to 88.2% in November. There are usually three generations of Ovis each year: the first March–April, the second in June–July and the last in September–October. There was no fly activity in winter and during the hottest months of summer. On the other hand, nearly all the larvae overwintered as the firs stage.
This study emphasizes the seriousness of the problem in the region and the authors recommend three strategic treatments per year during periods of high fly activity. 相似文献

A pilot survey using a structured questionnaire was conducted in Tororo and Busia districts of Uganda on the knowledge and attitudes of cattle owners regarding tsetse fly and trypanosomosis control, in order to understand factors that hindered their full participation. A total of 81 cattle owners was randomly selected and interviewed, of which 92.5% were aware of tsetse flies and trypanosomosis and 87.6% recognised animal trypanosomosis as a problem in the area. Most cattle owners were aware of tsetse fly trapping (76.5%), isometamidium chloride use (55.5%), diminazene aceturate use (48%) and pour-on applications (18.5%). However, knowledge did not coincide with the application of control measures. Despite the widespread awareness, tsetse fly trapping and pour-on applications were used by only a small percentage of cattle owners (7.5% applied tsetse fly trapping while 76.5% were aware of it; 1.2% applied pour-on insecticides while 18.5% were aware of them). Differences between awareness and application were highly significant for tsetse fly trapping (chi2 = 67.8, d.f. = 1, P < 0.001) and pour-on applications (chi2 = 10.8, d.f. = 1, P < 0.05), but not for isometamidium chloride use (chi2 = 0.08, d.f. = 1, P = 0.77) and diminazene aceturate use (chi2 = 0.00, d.f. = 1, P = 1.00). Most cattle owners (97.5%) were willing to participate in future control programmes, but preferred participating on a group basis (85.2%) rather than individually (14.8%). The 4 most favoured control options in order of importance were: fly traps supplied by the government and maintained by cattle owners; contribution of labour by cattle owners for trap deployment; self-financing of trypanocidal drugs and self-financing of pour-on insecticide. The control options that should be selected in order to elicit full participation by cattle owners are discussed. 相似文献

通过研究不同天气条件、不同时段果蝇的活动规律,为果蝇成虫诱杀技术的研发与应用提供理论依据。以果蝇为研究对象,设置不同处理,在现场研究果蝇在晴天、阴天、雨天及一天内不同时段的活动规律。在供试的6种成熟水果中,香蕉、蓝莓对果蝇的引诱效果显著高于其他4种水果(P＜0.01),绿如蓝牌果蝇引诱剂的引诱效果显著高于香蕉(P＜0.01)。在晴天,果蝇的活动更为频繁(P＜0.05),晴天诱捕到的雄果蝇数量明显高于阴天和雨天(P＜0.01)。诱捕到的果蝇种类主要是黑腹果蝇、斑翅果蝇、伊米果蝇、海德氏果蝇、筋果蝇等。一天内不同时间段果蝇的活动明显不同,8:00~10:00和16:00~18:00是其活动的两个高峰期。天气条件对果蝇活动有很大影响,一天内果蝇活动存在两个高峰期,分别是8:00~10:00和16:00~18:00,利用绿如蓝牌引诱剂可对果蝇成虫进行有效诱杀。 相似文献

Mammary gland lesions characterized primarily as mammary teat atresia were observed in a Limousin beef cattle herd in eastern Texas. Atresia of multiple teats per mammary gland was reported in first-calf heifers at the time of calving. Pathogens were not identified in eight mammary glands collected at slaughter. Histology of affected glands demonstrated superficial and deep perivascular inflammation and fibrosing dermatitis of teat and mammary gland skin that resulted in formation of the atretic lesions of glandular tissue. Institution of a horn fly (Haematobia irritans irritans (L.)) control program using insecticide-impregnated ear tags was associated with elimination of the problem from the herd. 相似文献
