Five prunus plants (Prunus persica, P. mume, P. serrulata, P. tomentose, and P. armenica) were tested for inhibition effect against Apis mellifera. Of those, P. persica leaves showed the strongest effect inhibiting the working of honeybee evidently. The major volatile compound of P. persica leaves was identified to be benzaldehyde by GC and GC/MS analysis. And then the ground leaves of P. persica were tested to inhibit or not the working of honeybee in hive for the purpose of its practical use, and showed enough inhibitive activity. After removing the ground leaves on hive, all honeybees repaired within 30 minutes. The ground leaves of P. persica was developed as a material inhibiting the working of honeybee to reduce the bee-keeper's labor on extracting honey through the design of treatment method.

Varroa is one of the most dangerous honey bee parasites, which causes serious damages to the bee industry. By now, various herbal and chemical drugs had been used against the parasite. In this research, the effect of 7 treatments including: tobacco, harmel and, thyme extracts, tobacco, harmel and thymus smokes and a control were studied on Varroa in 21 honey bee colonies as a completely randomized design (CRD) at three replications. The rate of hive contamination to Varroa at the beginning and end of the experiment and daily rate of varroa and worker bee mortality were recorded. There was no significant difference between experimental hives in view point of contamination toVarroa, at the beginning of the study.  However, significant dissimilarity was found out among treatments at the end of experimental period. Mortality rate of Varroa in different days and the whole period of the study was significantly different in treatments. Results revealed that tobacco and  harmel extracts caused the most Varroa and honey bee mortality, respectively.
