The tolerant effect of free amino acid and microelement diversity in haemolymph of honeybee larva to Varroa destructor

The newly reclassified ectoparasitic mite Varroa destructor(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 invade both drone and worker cells,but reproduce only in drone cells.Haemolymph of honeybee is the only food for survival and reproduction 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(A.cerana and A.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 component in haemolymph had correlation to the tolerance in A.cerana to Varroa destructor.
