Varroa jacobsoni oudemans
External and powerful, invasive parasitosis. Once it is present in the hive, year after year, the percentage of infestation increases until it kills the hive. Bees leave the hive with honey inside. The brood is dead, weak or smaller given that varroas suck hemolymph and delay development. The only place where the reproductive cycle of varroas is carried out is inside the capped cells. Therefore, the best results are obtained when THERE IS NO OR MINUMUN EGG-LAYING or when the queen is changed or by putting it in a cage for 4 or 5 days.
Treatment with: Colmesan LS or Colmesan ahumado


Acarapis woodie rennie
Internal parasitosis inside the tracheas, which hinders flight activity. It can cause signs of paralysis with the wings disjointed towards the front, intestinal disorders, disorientation and hovering near the vent opening. It can lead to the complete destruction of the hive and production can drop significantly.
Treatment with: Colmesan LS or Colmesan ahumado


Braula coeca
External paralysis located, preferably, on the back of the queen. However, lice can also parasite worker bees and drones. The greatest damage is economic given that lice feed on the food assigned to the queen. They can be identified and seen at a glance.
Treatment with: Colmesan LS or Colmesan ahumado


Gallería mellonella Achoira grisella
They always appear in weak, sick or badly-fed hives. They can destruct the hive. The greater wax moth causes “false tinea” and the lesser wax moth causes “wax tinea”. Due to the repugnant odour they cause, the hive may be abandoned and all the material can be damaged.
Treatment with: Colmesan LS + Polivitam


St.Pluton - St. Faecalis
B. Eurydice - B.Alvei
Also called brood roting, bacteria attack the larva before the capped stage and kill it after 4 or 5 days of life. It is highly infectious and contagious. It kills the larva that is then removed, which produces “reduction in brood production”, as it is also known. It causes putrid odour, decreases population and weakens the hive.
Treatment with: Colmesan PH Plus or Tetraloque + Polen Plus


Bacilus larvae white
Really serious disease in the brood that causes huge losses and attacks larvae after the capped stage. Larvae need to have medicine “bioavailability in advance” because after the cell is capped, it CANNOT BE medicated. Moreover, as the dead larva looks similar to “chewing gum”, removing it is impossible. Therefore, the cell remains occupied and it is not prepared for a new egg-laying. As a result, the hive dies progressively.
Treatment with: Colmesan PH Plus or Tetraloque + Polen Plus


Nosema apis zander
Internal parasitical disease, present in conditions where humidity and temperature favour the “sporulation” and multiplication of adult bees. It can cause acute diarrhoea that gets the roof of the hives dirty. It can also cause greasy and swollen abdomen, which hinders flight activity. Egg-laying is altered given that the ovaries of the queen and the hypopharyngeal glands are also affected, which decreases the production of royal jelly. It can cause excessive constipation due to the accumulation of parasitical remains. There are signs of anaemia and progressive weakness.
Treatment with: Colmesan PH Plus + Polen Plus or Polivitam


Ascophoera apis
This fungus attacks larvae and covers them completely. It hardens and takes the appearance of a chalklike little stone of several colours. There is a cotton floor appearance with perforated cappings and little stones on the floor.
Treatment with: Iodavet + Polivitam


ARN virus
This disease can be either acute or chronic. It is lethal in both cases. Establishing the differences with other pathologies is important. It can cause trembling, diarrhoea and hinder flight activity. The virus is transmitted by varroas. Thus, controlling varroas is a way to prevent paralysis. There are no specific treatments due to its viral aetiology.
Treatment with: Iodavet + Polivitam


Unidentified Bacteria
They are unidentified groups and their origin is unknown but highly infectious. Located away from the intestines, they appear as a septic centre causing strong putrid odour, unspecified diarrhoea and weakness. It is usually confused with Nosemosis but a difference has to be established. However, the same treatment is appropriate for both cases.
