The Study on the Tolerant Effect of Free Amino Acid and Microelement Diversity in Haemolymph of Honeybee Larva to Varroa destructor

The newly reclassified ectoparasitic mite Varroa de- structor(Anderson and Trueman 2000) is the most serious problem of A.mellifera worldwidely.But apparently,it is rather harmless in colonies of its original host A.cerana.As we know,In colonies of A. mellifera,Varroa destructor reproduces both in drone and in worker cells.In colonies of its original Asian host,Apis cerana,the mite in- vade both drone and worker ceils,but reproduce only in drone ceils. Haemolymph of honeybee is the only food for survival and reproduc- tion of Varroa mites,so it appeared that the concentration of some things in the haemolymph affect the reproduction of Varroa destructor. We compared the concentration of free amino acid and microelement in haemolymph of larvae (Apis cerana and Apis mellifera;drone and worker bee)that just sealed.And result showed that there are obvious diffrences in the concentration of free amino acid and microelement from different type of larvae.It suggested that the diversity of the com- ponent in haemolymph had correlation to the tolerance in A.cerana to Vartoa destructor.
