Relationship between dead pupa removal and season and productivity of honey bee (Apis mellifera, Hymenoptera: Apidae) colonies

Selection and Performance Evaluation of Local Honeybee (<i>Apis mellifera bandasii</i>) for Stock Improvement in Ethiopia

“…The highest dead pupae removal rate per colony was observed in colonies reared from the selected stock (94.3%) compared to the initial population and colonies maintained based on their first honey yield performances. This result is in line with the finding that colonies of the same subspecies within the same apiary demonstrate different level of hygienic behavior [8,9,19] suggesting that the higher dead pupae removal percent in colonies reared from the selected stock may reflect the substantial effect of selective breeding on improvement of colonies' hygienic behaviour expression. In addition, the observation provides a clue that hygienic behaviour may help the future selective breeding of better performing bee lines.…”

Bee’s morphometrics and behavior in response to seasonal effects from ecoregions

“…This supports the hypothesis that environmental conditions affect the expression of hygienic behavior. Panasiuk et al (2009) and Güler and Toy (2013), also, reported differences in removal rates between periods of high and low nectar flow that corresponded to months with relatively high and low precipitation. During rainy periods, there is more food available than during dry periods.…”

“…Although hygienic behavior is correlated with the expression of groups of genes (Lapidge et al, 2002;Oxley et al, 2010), its manifestation is believed to be determined by a complex interaction among environmental (Panasiuk et al, 2009;Güler and Toy, 2013), social (Panasiuk et al, 2010), and epigenetic factors (Herb et al, 2012).…”

“…This feature is called hygienic behavior (Rothenbuhler, 1964) and is a form of social immunity (Cotter and Kilner, 2010;Locke et al, 2012). Hygienic behavior is economically important due to its influence on colony resistance to parasites and pathogen infestations (Rosenkranz et al, 2010) and its relationship with other characteristics of interest, such as honey and propolis production (Wielewski et al, 2012;Güler and Toy, 2013;Padilha et al, 2013).…”
