Abstract
Apis mellifera jemenitica considered one of the most honey bee which were widely used in desert condition comparing with the other honeybee races. African hybrid honeybees have not been completely studied under desert conditions. So the current study has been designed to evaluate Apis mellifera jemenitica and Apis mellifera (carnica- lamarckii) hybrid under desert conditions inside and outside the tent. Forty honeybee colonies were used in this experiment, which were divided into 2 groups, each group contains 20 colonies. The 20 colonies from each group were further divided equally outside and inside the tent. The evolution of morphometric characters and colony performance, which include brood rearing, honey production, pollen storage, moreover temperature and humidity data were recorded and analyzed in order to compare the two groups inside and outside the tent. The morphometric results for A. melliefra jemenitica showed high similarity in Saudi Arabia.The morphological characters in current study of A. m. jemenitica and Apis mellifera (carnica- lamarckii) hybrid showed that there are a significant difference in length of the proboscis, cubital index and Color of tergites 3 and 4.Honey production inside and outside the tent was significantly higher in Apis mellifera (carnica- lamarckii) hybrid compared with Apis mellifera jemintica race, on the other hand Apis mellifera jemintica sealed drone brood significantly higher than Apis mellifera (carnica- lamarckii) hybrid during the tested period. The A. m. jemenitica hive temperature’s was significantly higher than the hive temperature of other exotic honeybee at 6 am inside and outside the tent. The hive RH in Apis mellifera (carnica- lamarckii) hybrid was significantly higher than the hive RH in Apis mellifera jemenitica in the three periods 6:00am, 12:00md and 6:00pm. In conclusion, the inside tent, reduce the temperature level significantly, in two periods 12:00md and 6:00pm in Apis mellifera (carnica- lamarckii) hybrid. However, both groups are surviving inside and outside the tent for various desert conditions
