Study on Varosis in Apis mellifera and study on effect of Apistan and Apigard in control of disease in karaj.

Varroa jacobsoni is an ectoparasite of honey bee and it is one of the most serious pests known for Apis mellifera. It feeds from haemolymph of the developing honey bee: larva/pupa and adult bee. Heavily infested colonies usually have large number of unsealed brood cell. Dead or dying newly emerged bees with nalformed wing, legs, abdomens, and thoraxes maybe present et the entrance of affected colonies if this parasitic disease left untreated mite cares loss of most affected colonies during one year. There are a lot of drugs for controlling varroa. In this research we studied 1000 sample (honey bee) from different part of karaj region Tehran province and infestation rate was 36.8%. Also studied the effect of Apistan and Apigard on the infestation rate and we saw Apistan was rather more effective and no resistance was observed to these two Drugs.
