Agriculture and Forestry Research, Special Issue No 362 (Braunschweig, 2012) ISSN 0376-0723 Download: www.vti.bund.de/en/startseite/vti-publications/landbauforschung-special-issues.html The number of Varroa d. adults and the beehive strength never showed significant difference between groups. Beehive weight resulted significantly higher in July than in April. Honey production was higher in April (Acacia honey) than in July (Chestnut honey) but in both cases there weren’t significant differences between groups. At first, Nosema spp increased, and then it completely disappeared on group C (Figure 2). From the genetic characterisation of Nosema spp. it resulted that all the samples analysed belonged to N. ceranae. It recently spread on large European areas, substituting the indigenous N. apis, with completely different symptoms from the classic Nosemosis. Several viruses were detected on beehive in both groups in different times. The KBV virus was never detected. Figure 2. Incidence of Nosema ceranae within the experimental groups Discussion There is much research on the efficiency of homeopathy in organic farming, but there is very little work of organic beekeeping. Indeed, the studies of this subject are very few in the international scientific literature (Ruiz Espinoza and Guerrero Salinas, 2003, 2004) and only one at national level (Persano Oddo and Marinelli, 2002). Group C, after the Api-Bioxal treatment, showed a mite fall lower than group W. This result was similar to those obtained by researchers of Universidad Autónoma de Chapingo of Mexico (Ruiz Espinoza and Guerrero Salinas, 2003, 2004) using Varroa destructor 202 CH nosode and Sulphur 202 CH. The meaning of the lower mite fall, if confirmed, could demonstrate the positive effect of Calcarea Sulphurica 200 CH on improving the resistance of honeybee’s families towards Varroa d. In addition, Nosema spp. disappeared on group C and also this effect could be associated to Calcarea Sulphurica 200 CH. These results should be checked with other further trials. At present, we have just started a second trial, in another apiary, to investigate the efficiency of this homeopathic treatment. 468

Proceedings of the 2 nd OAHC, Hamburg/Trenthorst, Germany, Sep 12-14, 2012 Suggestions to tackle the future challenges of organic animal husbandry Our work had the worth to develop a holistic study model of an apiary, considering at the same time different aspects such as biological, productive and pathological ones. We used the model to test homeopathy integrated with biomechanical treatments in an organic apiary to control pathologies, but this should be useful to test other remedies or drugs on organic beekeeping.
