RESUMEN
Brood infestation with the parasitic bee mite, Varroa jacobsoni oudemans, and the impact of two plant oil extracts on infestation were studied in the Nubareya region, Egypt. Drone broad infestation ranged between 12.44 +/- 2.9 and 21.67 +/- 3.9%, while the worker's ranged between 6.44 +/- 1.5 and 10.4 +/- 1.9%. The highest infestation was recorded during August for both drone's and worker's brood. The application of eucalyptus oil extract showed a positive reduction in the percentage of infestation. The maximum effect was observed after 21 days and was maintained till day 30. The effect of matricary oil extract application was faster. Its maximum effect was strongest between days 7 and 15. Eucalyptus highest effect on worker's brood was after 30 days, while the highest effect of matricary was after 15 days. Both applications on drone and worker broods showed a significant infestation reduction, especially by the end of the experiment
