“…The type of storage for the honeybee queens after emergence is part of the care for the efficient reproduction, since there is a waiting time required for their introduction in their respective colony. Gilley et al (2003) and Kahya et al (2008) verified an association between reproductive quality of the queen with weight at emergence and Akyol et al (2008) concluded that heavier queens had higher mating rates and started laying eggs earlier than lighter queens. As a result, queen weight is studied as a selection criterion in honeybee breeding programs (Souza et al, 2013) due to high heritability.…”

“…Costa-Maia et al (2011) estimated genetic and phenotypic parameters, via Bayesian inference, for weight and morphometric measurements of wing and abdomen in newly emerged Africanized honeybee queens and registered potential selection in all characteristics separately. Akyol et al (2008) reported that queen weight is the most important among morphometric characteristics assessed given the positive correlation between queen weight and the brood area of the colony, the number of sperm and the diameter of spermatheca. In addition to this correlation, Akyol et al (2006) observed a variation between morphological and physiological characteristics between subspecies and ecotypes.…”

ABSTRACT. This study aimed to estimate live weight, the length and the width of wing and abdomen and the length, the width and the height of thorax in newly emerged Africanized honeybee queens up to 192 hours and their influence on final quality regarding appropriate storage techniques in queen banking or incubator and to verify the possibility of using these parameters as selection criteria in honeybee breeding programs. Queen honeybees were produced in summer, autumn and winter. The queen production method used throughout the experiments was adapted from Doolittle, and 68 the queens were weighed at emergence. Data were analyzed in R software by regression analysis of queen weight at emergence according to life time after emergence, in two types of storage. The weight of queens emerged in queen banking and incubator was significantly different (p < 0.05), with mean values of 165.61 and 157.04 mg, respectively. Queens kept in an incubator and in queen banking showed no significant differences (p > 0.05) in wing length, abdomen length and thorax height. The weight of queen at emergence can be used as a selection criterion in honeybee breeding programs.Keywords: queen size, emergence, honeybee breeding, queen production.Medidas morfométricas de rainhas africanizadas mantidas em estufa ou colmeia banco de rainhas RESUMO. O objetivo do trabalho foi estimar peso vivo, comprimento e largura de asa e abdome e comprimento, largura e altura do tórax de rainhas Apis mellifera africanizadas recém-emergidas até 192h e sua influência na qualidade final com relação às técnicas apropriadas de armazenamento em banco de rainhas ou estufa e verificar se estes parâmetros podem ser utilizados como critério de seleção. Foram produzidas nas seguintes estações do ano: verão, outono e inverno. O método utilizado durante todo o experimento foi o adaptado de Doolitlle para a produção de rainhas e 68 rainhas foram pesadas à emersão. Os dados foram analisados no software R pela análise de regressão do peso da rainha à emergência em função do tempo de vida após a emersão, nos dois tipos de alojamento. Para peso, os efeitos da colmeia banco de rainhas e estufa foram significativos (p < 0,05), médias de 165,61 e 157,04 mg, respectivamente. As rainhas mantidas em estufa e colmeia banco de rainhas não apresentaram diferenças em relação ao comprimento da asa, ao comprimento do abdome e à altura do tórax. O peso de rainhas à emergência mantidas em colmeia banco de rainhas foi maior que o peso das rainhas mantidas em estufa. O peso das rainhas à emergência pode ser utilizado como critério de seleção.Palavras-chave: tamanho de rainhas, emersão, melhoramento de abelhas, produção de rainhas.

“…Africanized queens of mini-hives originated from 15 mother queens. Gonçalves and Kerr (1970), Kerr et al (1970a, b) and Akyol et al (2008) recommended the use of queens weighing more than 200 mg at emergence. Therefore only queens with an initial weight above 180 mg were introduced in the mini-hives.…”

Potential use of major royal jelly proteins (MRJPs) as molecular markers for royal jelly production in Africanized honeybee colonies

et al. 2009

-The present study determined the genetic variation at mrjps loci (mrjp3, mrjp5 and mrjp8) and evaluated the potential use of MRJPs as molecular markers for higher royal jelly production in Africanized honeybee colonies. The three analyzed loci produced a total of 17 alleles. This high allelic polymorphism indicated these loci could serve as genetic markers. The potential use of MRJPs as molecular markers for royal jelly production was evaluated by analyses of multiple linear regressions with EPD (expected progeny differences) values for royal jelly production. The variance analyses indicated that the mrjp3 repetitive region influenced the genetic value of queen's offspring for royal jelly production. The determination coefficient (R 2 ) for the significant alleles of the repetitive region of mrjp3 indicated that 36.85% of the EPD variation is explained by the variation of C, D and E alleles. Therefore, these three alleles present a considerable genetic effect on the variation of RJ production.Apis mellifera / MRJP-3 / genetic variability / polymorphism / EPD

“…Dengan demikian, teknik pencangkokan dengan larva muda akan menghasilkan calon ratu dengan kualitas yang lebih tinggi, karena memiliki ukuran tubuh yang relatif lebih besar dan bobot lebih berat yang memungkinkan memiliki jumlah ovariol dan daya simpan sperma yang lebih banyak. Hal ini dibuktikan oleh Emsen (2004) dan Akyol et al (2008) yang menemukan adanya korelasi positif antara bobot tubuh lebah ratu dengan jumlah spermatozoa di dalam spermateka dan tingkat penelurannya. Temuan ini sejalan dengan hasil penelitian Gencer et al (2000) yang menemukan bahwa lebah ratu yang bobotnya lebih berat menghasilkan sarang anakan yang lebih luas dibandingkan dengan ratu dengan bobot yang lebih ringan.…”

ABSTRAKPercobaan teknik cangkok berbagai umur larva lebah madu Apis cerana L. ditujukan untuk mengetahui potensi kualitas ratu yang akan dihasilkan. Empat perlakuan larva umur 1, 2, 3, dan 4 hari diaplikasikan pada uji coba pencangkokan, masing-masing sebanyak 5 mangkok ratu di setiap koloni percobaan. Dalam penelitian ini digunakan 5 koloni lebah madu A. cerana sebagai ulangan percobaan. Bobot pupa digunakan sebagai indikator potensi reproduktivitas ratu yang akan dihasilkan. Hasil penelitian menunjukkan bahwa umur larva berpengaruh terhadap tingkat penerimaan larva yang dicangkokan dan bobot pupa calon ratu. Tingkat penerimaan larva lebih tinggi pada larva muda dibandingkan dengan larva yang lebih tua sebagaimana ditunjukkan oleh jumlah perkembangan sel ratu yang berhasil dierami. Jumlah rata-rata sel yang berkembang menjadi sel ratu dari hasil pencangkokan larva umur 1, 2, 3, dan 4 hari berturut-turut sebanyak 4,4 ± 1,1 sel/ koloni, 3,4 ± 1,1 sel/koloni, 2,0 ± 1,0 sel/koloni, dan 2,4 ± 0,5 sel/koloni. Larva umur 1 dan 2 hari menghasilkan pupa dengan bobot yang lebih berat dari pada yang berasal dari larva umur 3 dan 4 hari. Larva umur 1, 2, 3, dan 4 hari berturut-turut menghasilkan pupa dengan berat rata-rata 153,33 ± 4,48 mg/individu, 149,14 ± 6,29 mg/individu, 126,17 ± 7,28 mg/individu, dan 126,70 ± 7,61 mg/ individu. Tidak ada perbedaan bobot pupa antara hasil pencangkokan dengan larva umur 1 dan 2 hari dan antara larva umur 3 dan 4 hari. Dengan demikian, larva umur 1 dan 2 hari berpotensi menghasilkan lebah ratu yang lebih berkualitas dibandingkan dengan larva umur 3 dan 4 hari. Kata kunci: Apis cerana, pencangkokan, umur larva, tingkat penerimaan, bobot pupa ABSTRACTAn experimental study to find out the effect of larval ages to the quality of queens produced through queen-grafting technique has been done in Apis cerana colony. Each of four larval ages (1-4 day-old larvae) was grafted into 5 queen cups in every single colony. Five colonies were used in the study as experimental replications. Pupal weight was used as initial indicator of potential reproductivity of upcoming queen. The results showed that larval age affected both the acceptance rate of grafted larvae and queen pupal weight. The acceptance rate of young larvae was higher than old larvae as shown by their successful number of capped queen cells development. The mean number of capped queen cells developed from larvae at the age of 1, 2, 3, and 4 day-old were 4.4 ± 1.1 cells/colony, 3.4 ± 1.1 cells/colony, 2.0 ± 1.0 cells/colony, and 2.4 ± 0.5 cells/colony, respectively. The queens reared from 1 and 2 day-old larvae significantly had heavier pupae than those from both 3 and 4 day-old larvae. The mean pupal weight grafted from 1, 2, 3 day, and 4 day old larvae were 153.33 ± 4.48 mg/pupae, 149.14 ± 6.29 mg/pupae, 126.17 ± 7.28 mg/pupae, and 126.70 ± 7.61 mg/ pupae, respectively. There were no differences between pupal weight grafted from 1 and 2 day-old larvae and between pupal weight grafted from 3 and 4 day-old larvae. The study showed that 1 a...
