Abstract

Varroa parasite is the primary pest affecting honeybees and it is ranked first among diseases and pests that are most detrimental to bees globally and in the Arab world. Varroa parasite is dangerous because it reproduces quickly and spreads widely, killing off and destroying bee colonies. The aim of this study was to examine and assess the prevalence of Varroa on worker bees and honey bee colony incubators. Susceptibility tests were carried out to evaluate the prevalence of Varroa infection in colonies with covered brood, on adult workers, and on grooming and hygiene practices. The analysis of adult worker and brood samples from Varroa-infected honey bee strains revealed notable differences between the strains. The Italian hybrid had the highest average infection rate (19.20%), while the Egyptian hybrid had the lowest infection rates (11%). Lastly, the infection rates in Egyptian (Upper Egypt) and Carniola hybrids were medium (12.2 and 13.60%, respectively). Additionally, the evaluation of various chosen breeds' health behaviors was investigated. According to the data, Egypt (Upper Egypt) had the highest average percentage of dead brood that was removed and left exposed after twenty-four hours, 40.4, ranging between (40:42), i.e. healthy colonies. The local Carniola hybrid strain, 34.2, had the lowest value, ranging from It is considered unhealthy and falls into the average range of 30:39. Both the Egyptian (Alexandria) strain and the native Italian hybrid strain had scores of 34.4 and 39.8, respectively. For Al-Masry (Upper Egypt), the average percentage of removed and uncovered brood was 94, with a range of (98:95).The local Carniola 79 hybrid strain had the lowest average percentage, ranging from (69:90). After 48 hours, the Italian hybrid strain from the area and the Egyptian colony (Alexandria) recorded 92 and 80, respectively. The Carniola hybrid strain had the highest percentage recorded at 65.8, which ranged between (61-70), and the lowest value recorded in Egypt (Upper Egypt) was 59.6, which ranged between (58-61). These results were based on the average percentage of dead brood that was not removed or covered after 24 hours. The Egyptian (Alexandria) breed received a score of 60.2, while the local Italian hybrid breed received a score of 65.6. The local hybrid Carniola breed had the highest average percentage of dead brood that was not removed after 48 hours, according to the results. The local Italian hybrid strain and the Egyptian (Alexandria) strain recorded 20 and 8%, respectively, while the Egyptian (Upper Egypt) strain recorded the lowest value, 6, which ranged between 2 and 10.
