“…In earlier studies it was demonstrated that the drones developing at a constant low temperature of 32°C have higher body mass than those developing at a constant higher temperature of 35°C (Szentgyörgyi et al 2018;Czekońska et al 2019). The results presented here show that the drones can achieve even higher body mass when they develop during the post-capping period at temperature which changes from 35°C to 32°C.…”

“…Both the body mass and the body size of the drones are believed to be a good predictor of their quality (Nylin and Gotthard 1998;Szentgyörgyi et al 2016;Czekońska et al 2019). Larger drones Body mass of honey bee drones produce a greater number of spermatozoa (Schlüns et al 2003;Gençer and Firatli 2005;Taha and Alqarni 2013), start mating flights earlier (Rueppell et al 2006), are more likely to mate with a queen (Koeniger et al 2005;Couvillon et al 2010;Slone et al 2012), live longer, and their chance of surviving maturation is higher (Czekońska et al 2019). It is known that the honey bee colony can influence the reproductive quality of the drones (Boucher and Schneider 2009;Slone et al 2012).…”

“…The body mass of the drones depends not only on their development but also their environment after emergence (Szentgyörgyi et al 2017;Czekońska et al 2019). The factors that affect the body mass of the newly emerged drones include feeding, number of attending workers, and nest temperature (Haydak 1970;Free and Williams 1975;Hrassnigg and Crailsheim 2005;Czekońska et al 2015;Szentgyörgyi et al 2016).…”

“…Drones developing in a constant temperature of 32°C have bigger reproductive organs, their spermatozoa are more viable, but the volume of the semen is lower in comparison with drones developing in a constant 35°C (Czekońska et al 2013). Moreover, the drones developing at lower temperature are bigger and heavier (Szentgyörgyi et al 2018;Czekońska et al 2019).…”

“…In unfavorable environmental conditions caused by malnutrition or low ambient temperatures, the drones can be selectively evicted from the colony (Seeley and Mikheyev 2003;Hrassnigg and Crailsheim 2005;Czekońska et al 2015). Drones which developed in a constant higher temperature (35°C) were smaller and were evicted more often in comparison with drones which developed in a lower temperature (32°C) (Szentgyörgyi et al 2018;Czekońska et al 2019). The quality of drones affects longevity and fertility of the queen (Brutscher et al 2019;MetzandTarpy2019;Rangel and Fisher 2019).…”

The body mass of honey bee (Apis mellifera) drones was investigated during a post-capping development under four temperature regimes: constant low temperature (32°C), constant high temperature (35°C), low temperature in the early stage followed by high temperature in the later stage, and high temperature in the early stage followed by low temperature in the later stage. The temperature regimes had significant influence on the drones' body mass. The heaviest drones were obtained when the temperature was high at the early stage and low at the later stage of the post-capping period. The most lightweight drones occurred at constant high temperature. The body mass of drones was changing significantly over their adult life and was highest at the age of five days. After this age, the body mass tended to decrease until the end of life. These results suggest that the highest body mass of drones can be obtained by keeping them during the post-capping development in changing and not constant temperatures.

Sperm competition in honey bees (Apis mellifera L.): the role of body size dimorphism in drones

Previous experimental studies demonstrated that small drones (SD) had lower paternity share since they were not successful in mating with queens as large drones (LD) in the mating arena. However, it remains unclear whether spermatozoa of SD can compete in vivo with those of LD if SD have mating opportunity. We, therefore, tested the spermatozoal competitiveness of SD against LD by instrumentally inseminating the queens with varying proportions of semen from LD and SD. Sister queens from a Buckfast colony and LD and SD from 15 Caucasian colonies were reared synchronously as experimental test individuals. The virgin sister queens were randomly allocated into three semen composition groups. The queens in groups A, B and C were inseminated with an equal volume of semen (7.2 μl) collected successively from 6 LD and 6 SD (50%:50% treatment), 3 LD and 9 SD (25%:75% treatment), and 9 LD and 3 SD (75%:25% treatment), respectively. Once oviposition starts in mating nucs, the queens were introduced into field colonies to proceed to lay eggs. After 3 months, about 100 newly emerged worker daughters from each queen were individually collected from the colonies for paternity assignment. Five polymorphic microsatellite loci (A024, A079, A43, A113, and Ap226) were analysed in 144 drones that were used to inseminate 12 experimental queens and 908 offspring workers. The observed patriline frequencies of LD and SD were 67.0% and 33.0% in group A, 34.6% and 65.4% in group B, and 79.8% and 20.2% in group C, respectively. The patriline frequencies within each colony were noticeably skewed. LD that were reared in QRC sired more offspring, whereas SD that were reared in LWC had lower paternity shares. When all three semen composition groups were pooled, the overall observed patriline frequency of SD (40%) was found to be 10% less than the overall expected patriline frequency (50%). The results demonstrated that SD remained a little behind LD in sperm competition.

Stingless bees in urban areas: low body size and high frequency of diploid males at mating congregations of Nannotrigona perilampoides (Hymenoptera: Meliponini) in Mérida, Yucatán, México

In temperate regions of the world dominated by intensive agriculture, cities harbor a rich diversity and abundance of bee species, often exceeding those of the rural environment. In less industrialized tropical countries, in contrast, stressful conditions may exist in cities for bees with perennial colonies such as stingless bees because of the lack of resources such as amenity green spaces (flowers) and appropriate nesting sites. Yet, we currently lack studies on the ecology of bees in tropical urban areas to test this idea. Here, we compared the body size (as a possible indicator of floral resource supply) and the frequency of diploid males (as a measure of inbreeding) of a widespread stingless bee, Nannotrigona perilampoides , at mating congregations within the city of Merida, Yucatán, Mexico, and in surrounding rural areas. We found that males in Merida were significantly smaller compared with those in rural areas. While diploid males were found in both in the city and rural congregations, their frequency was significantly higher in urban sites. Our results suggest that the performance of colonies of N. perilampoides is poorer in tropical urban compared with rural sites, possibly as a consequence of limited resources and mating among a small number of colonies. We discuss the implications of these findings for the survival and fitness of stingless bees in the tropics.Urbanization / deforestation / microsatellite / heterozygosity / Meliponini / inbreeding
