Morphometric Studies on Dwarf Honey Bee Apis Florea F. Workers in Saudi Arabia

Here we performed a morphometric analysis of dwarf honey bee (Apis florea F.) workers from Saudi Arabia, and we detected morphometric variations within the species in the Jubail and Al-Ahsa provinces of this region. Between the two provinces, Jubail is further north and is closer to sea level, and data showed that during the collection period, Jubail experienced significantly higher humidity. Compared to workers from the Jubail province, workers from Al-Ahsa province showed significantly higher body weight, measured head appendage characteristics, wing characteristics (apart from hindwing width), leg characteristics, and length and width of the 3^rd abdominal sternite and 1^st wax mirror. Body weight as found to be significantly positively correlated with all determined characteristics, except for flagellum length, hindwing width, 3^rd tergite length, and lengths of the 4^th tergite and sternite. It can be concluded that body weight and morphometric characteristics of dwarf honey bee workers were significantly affected by geographic origin. The morphometric measurements were within the range reported from most previously examined countries.
