“…Hygienic honey bee workers have the ability to detect diseased brood, uncap the wax covering over the brood cells and remove the infected larvae or pupae. The impact of hygienic behavior on the spread of infective diseases is maximized if it takes place before the causative organism reaches the infectious sporulating stage [118,119,139].…”

“…2). Although we used larval extracts, we can assume that larvae would have a good resistance against an infection in vivo because data from the literature (Woodrow and Holst, 1942;Bailey and Lee, 1962;Bamrick, 1967) show that young larvae (two-, three-and fourday old) have increasing resistance with increasing age. There are different explanations Figure 3.…”

“…Woodrow and Holst (1942) demonstrated that larvae older than two days were less susceptible to an infection with AFB. Haydak (1943) showed that the composition of the larval food changed during larval development.…”

-Paenibacillus larvae larvae, a Gram-positive and spore-forming bacterium, is the cause of American foulbrood. We investigated the resistance of larvae of different ages from different colonies against P. larvae larvae. We prepared ethanol-water-extracts from two, three, four and five day old larvae and also larvae in two capped stages to test the ability of the homogenates to inhibit the growth of P. larvae larvae in vitro. There were age and colony dependent differences in the inhibiting potentials of larvae. The results suggest that the concentration of the inhibiting substance(s) in the extract might be responsible for the known different degree of resistance against P. larvae larvae in vivo. Our results further show that the extracts of the two-, three-and four-day-old larvae have the ability to inhibit the growth of P. larvae larvae very well, while starting around day five the inhibiting effect is gradually reduced.Apis mellifera carnica / Paenibacillus larvae larvae / honeybee larvae / age-related resistance /

“…Individual adult bees that express the hygienic trait uncap and DOI: http://dx.doi.org/10.22192/ijarbs.2017.04.02.002 remove diseased brood from combs before the pathogen is transmissible, thus reducing the spread of infection in the colony (Rothenbuhler, 1964a, b). At the colony level, hygienic behavior is a mechanism of reissuance to two brood diseases, American foulbrood and chalk brood (Park et al, 1937;Woodrow and Host, 1942;Rothenbuhler, 1964a, b;Gilliam et al, 1983;Milne, 1983;Taber, 1986;Spivak, 1996;Palacio et al, 2000;Spivak and Reuter, 2001). Hygienic behavior also has been studied as one colony-level mechanism of resistance to the parasitic mite, V.destructor, through the bees' removal of infested pupae (Boecking and Drescher, 1992,;Moretto, 1993;Spivak, 1996;Reuter and spivak, 1998).…”

Hygienic behavior of honeybee workers involves inspection, uncapping and removal of diseased and dead brood from the colony cells. The present study was conducted to clarify the effect of three compounds as therapy treatments against certain disease and pests on honey bee workers hygienic behavior as percentage in the presence of pin-killed brood. Colonies were more efficient in the removal activity of dead brood, 24 hours after application. The removal activity of dead brood was significantly higher after treatment as compared with that recoded before treatment, being 5.00, 3.67 and 4.33 % after using marjoram oil, oxalic acid and Oxytetracycline (Terramycin ), respectively. The corresponding percentages before treatment were 17.33, 14.00, and 13.67 % of brood, respectively.
