Spatial epidemiology of the Asian honey bee mite (Varroa destructor) in the North Island of New Zealand     

M.A. Stevenson  H. Benard  P. Bolger  R.S. Morris 《Preventive veterinary medicine》2005,71(3-4):241

We describe the spatial epidemiology of Varroa destructor infestation among honey bee apiaries in the greater Auckland area of the North Island of New Zealand. The study population was comprised of 641 apiaries located within the boundaries of the study area on 11 April 2000. Cases were those members of the study population declared Varroa-infested on the basis of testing conducted between April and June 2000. The odds of Varroa was highest in apiaries in the area surrounding transport and storage facilities in the vicinity of Auckland International Airport. A mixed-effects geostatistical model, accounting for spatial extra-binomial variation in Varroa prevalence, showed a 17% reduction in the odds of an apiary being Varroa infested for each kilometre increase in the squared distance from the likely site of incursion (95% Bayesian credible interval 7–28%). The pattern of spatially autocorrelated risk that remained after controlling for the effect of distance from the likely incursion site identified areas thought to be ‘secondary’ foci of Varroa infestation initiated by beekeeper-assisted movement of infested bees. Targeted investigations within these identified areas indicated that the maximum rate of local spread of Varroa was in the order of 12 km/year (interquartile range 10–15 km/year).  相似文献

破壁蜂花粉对蛋鸡免疫功能及肠道菌群的影响     

王允超  李桂杰  路建彪  朱瑞良 《家畜生态》2005,(6)

试验将槐花蜂花粉进行振动磨超微粉碎破壁,分别按1 g/kg、5 g/kg、10 g/kg三个不同剂量混到蛋鸡饲料中,从7日龄开始饲喂至50日龄,每个剂量分两个试验,试验一用新城疫Ⅳ系疫苗免疫雏鸡,利用β-微量法监测血清中的血凝抑制抗体效价的动态变化;试验二用大肠杆菌油乳苗免疫雏鸡,利用间接血凝法监测血清中大肠杆菌抗体效价的动态变化。分别定期称重捕杀取脾、胸腺、法氏囊,计算免疫器官指数,取肠道内容物计数大肠杆菌和乳酸菌,测定肠道内pH值。结果表明,不同剂量的破壁蜂花粉均能不同程度地提高病毒抗原性抗体效价和菌体抗原性抗体效价,对雏鸡免疫器官的发育以及肠道内环境、菌群的平衡也有一定影响。  相似文献

Computing inbreeding coefficients and the inverse numerator relationship matrix in large populations of honey bees          下载免费PDF全文

The inbreeding coefficients are considered in breeding decisions, and the inverse numerator relationship matrix A ^?1 is a prerequisite for breeding value estimation. Polyandry and haploid males are among the specifics of relationships between honey bees. Brascamp and Bijma (2014) averaged out the manifold possible relationships among honey bees that appear to have the same parents in a pedigree and assigned a single entry in A to animals that behave as a unit, for example, the workers of a hive. Their methods of calculation connected full‐sibs in the variance matrix of the Mendelian sampling terms D , via nonzero off‐diagonal elements. This impedes the inversion of A and the closely connected calculation of inbreeding coefficients, because efficient algorithms for this task take D to be a diagonal matrix. Memory limitations necessitate their use for large data sets. We adapted the quickest of them to the block diagonal matrix D , that is postulated for the honey bee. To our knowledge, the presented algorithm is the first one that facilitates the method of Brascamp and Bijma (2014) on large data sets.  相似文献
