Hopping to make useful mu experiences gained in the cours of my 20 years work with LR bee hives, I decided to take part in the III rd International Symposium and deliver these modest experiences to those beekeepers who have also serious problems with Varroe. I wish this presentation would leave a certain trace and would be of a great use to the beekeepers in their future work. Now I am going to present you one of my experiments made last yar which was based on scientific sources and has showed excellent results this year. As a pharmacist I should like also to offer you my opinions of the remedies used in suppression the Varroe. My successful experience of beekeeping has been a result of my long patient work in this field and reading professional journals. In the future I shall have more time and opportunities, as a director of the military beehive, to make experiments, researches and prove some scientific knowledges from this field. Therefore I offer cooperation to all scientific insti­tuts and faoulties throughout Yugoslavia who are in some way occupied with beekeeping.The experiment which I have made on two bee hives and which I shall use it for suppression Varroe in the future, is a result of my conversation with Dr Jovan Kulinchevich who advised me that the Chinese beekeepers successfully strive against Varroe with cuting off the last brood. Afterwards I have something modificated, and adopted it to LR bee hives. Therefore I can say that this experiment proved a great effectiveness.From two beehives, so called matorke, which finished the­season of the 17 th of August,1983,with 3 additions, I took out the frames with clesed brood and half closed brood where I thought there was a great number of Varroe and put them in another bee hive. I added to this frame with brood some bees from onother beehive to help the bees come out from the brood in the following 15 days. I left 19 frames in each of these two matorke. Two frames were with eggs and opened brood but without Varroe in thew. Also I left 17 frames with some quantity of honey, pollen and several empty frames where the yourg qween bee can continue undisturbed to lay eggs (1 change the queen bee every July). The same day, on the 17 th od August 1983, before the night fall, after all the bees had returned from the pasture, I filled the bee hives with comon smoke so they could fill the honey bublles with honey, stetch out the back and open the spaces between the hitins rings so that the remedy could be more effective. After that I treated them with a stream of smoke made of Apiacaridim /not 2×2 smokes/ because I am in a possession of an electric smoke machine with a ventilator where the charcoal begins to burn so easily, produce high temperature and do not leave coal monoxide which is a strong poisonous gas. If the charcoal does not burn out complet­ ly it will have serious consequenses on the bees. Besides these two matorke I treated the extension­ with 8 frames filled with brood and small number of bees. The result of this treatment is as following. In the two matorke each with two storries I noticed that about 3-5% of Varroe have fallen off. As concern to the ad­dition I did not notice anything. The next day, on the 18 th of August 1983, I repeated the treatment once more in the matorke but a small number of Varroe has fallen off. Startingfrom the 18 th of August I began to feed the matorke every with 300-400 gr. of sugar syrup 1:1.Instead of the 2 oth frame /7 needed a place to move apart the frames during the treatment/ put a frame with a sugar pie which gives guarantee taat the young queen bee will continue successfully with laying eggs. According to the literature the queen bee lays about 450 eggs every day from the 16 heof August till the 6 th of September but from the 6 th of September till 27 th of September lays about 83 eggs. To my opinion the young queen bee can lay more eggs if it is supplied with optimal condition for that. Before I had to go attend the Congress apimondija in Budapest on the 24 th of September 1983, I had treated only that bee hive from which extension the yourg bees could come out from the closed brood. I noticed that the same quantity of Varroe had fallen offas it had in the two matorke before (When I looked at the drone cells to see if there was Varroe I could find about 5 – 6 Varroe in every cell). During my absence, from the 24 th of August 1983, till the 2 nd of September 1983, I obligated somebody to continue with feeding the twe matorke. When I came back on the 3 rd of September once more I treated the extension and noticed that the same number of Varroe has fallen off as the previous time. Because there was not any more closed brood in the bee hive. I treated also the extension the next day, on the 4 th of September 1983, bnt there was not any Varroe. In this extension there could be found every kind of bees without wings, without legs and with some other deformities which I returned the next day to that bee hive from which I took it out. To this bee hive I added the bees from the matorke on the 6 th of September1983, I noticed that there was brood on six frames in them. Neht checking was on Novemher 19, 1983. There were no nests.I treated them once more, but Varroe was a few.I think that with such treatment i reduced it to the lowest limit. With this date I concluded the wintering. According to my free calculations, the honey reserves were between 15 and 18 kilos, and the bees were covering 8 lanes each. We can draw a conclusion that, although we reduced a covered nest before its closing from one beehive (if we do it on time) it can not influence effectivelly on the compactness of the bee society in winter and in spring. In spring, on May 15, 1984, instead of the frame, the bee-workers were given building material and the third appendix. I controlled the building material on June 16,1984, and in 500 cells of drones I found 18 in the first, 12 Varroa in the second. I concluded that in the nest i have 3,6% in the first, 2,4% in the second of the infection and i think that it can not affect to the society, and I haven’t done anything else. On August 4, 1984, I came to take honey. From the first I took 16, from the second 17 full frames with honey and 60 kilos honey. I am satisfied because I dealed with stationary beehives which are on a great distance from my home. We can draw one more conclusion. This method didn’t effectivelly influenced on honey harvest. When I write this paper, on August 26, 1984, I can show one conclusion more. The infectioon is less than last year’s. I think that this kind of method can be applied every second year.

       At the end, my conlusion is as follows:
1) In August, more precisely, from August 15, to apply the above described method, once a year or once in two years.
2) In November, when there are no nests, if we apply this method each year, one tretament, or if we apply it once in two years, then it can ve done in the year when this method isn’t performed, with triple treat ment with some medicaments.
3) In spring, in May, to put building material for checking, and if it is neccessery, to fight vlith this method by cutting of the drone nest.

‘d like to state and I announced it before, and I feel as my duty as pharmacist to inform the beekeeepers about two fundamental princip les about the usage of medicaments. The beekeeperes who accepted the fact that the medicaments will be included in their work, must read more and must realize the principles as follows:
1)The graduality of medicament applying – from weaker to stronger.
2)The right usage of medicaments, because it can serve as poison or it can not affect because of ill storage. If we do not recognize these two principles, a lot of beekeepers suffered great losses.I do not aqree with some beekeepers who use more medicaments in a year, e.g., in one treatment cycle.
            Some beekeepers put 2, 3, and more medicaments in one chimney tax. They cannot see the consequences of their fault. The consequences are as follow:
1) Quick resistence of the parasites, e.g., the resistence of the parasite to such medicaments, and in a lack of new and more effective medicaments they doom themselves to disaster.
2) It is known that some medicaments can not stand together, that if they mix together can produce a poison, or they neutralise each other and the efficiency is at minimum.
