Produção de geléia real com abelhas africanizadas selecionadas e cárnicas híbridas

Abstract

RESUMO -O objetivo foi avaliar a produção de geléia real em colônias de abelhas Apis mellifera, em comparação às africanizadas selecionadas para a produção de geléia real, africanizadas selecionadas para mel com cárnicas híbridas. No experimento I, foram utilizadas 10 colônias de abelhas africanizadas após seleção, para produção de geléia real; as cinco melhores rainhas foram substituídas por suas filhas e, nas restantes, foram introduzidas rainhas cárnicas, para avaliação da produção após troca da população. No experimento II, foram utilizadas 15 colônias, cinco com rainhas africanizadas selecionadas para a produção de mel (AFML), cinco selecionadas para a produção de geléia real (AFGR) e cinco cárnicas híbridas (CAHB). No experimento I, as cárnicas híbridas apresentaram maior produção de geléia real/colônia/coleta (3,95 ± 2,92 g) que as africanizadas (2,23 ± 2,13 g). As cárnicas foram superiores quanto à porcentagem de aceitação de larvas (55,4 ± 36,7%) às africanizadas (35,8 ± 28,3%). Quanto à produção de geléia real/colônia/coleta (g), no experimento II, as abelhas AFML foram significativamente superiores (4,42 ± 2,67 g) às CAHB (3,30 ± 1,85 g) e às AFGR (3,71 ± 2,13 g), que não diferiram das anteriores. Ambas as africanizadas, AFML e AFGR, produziram mais geléia real por cúpula (254,2 ± 90,7 e 253,8 ± 206,8 g, respectivamente) que as CAHB (195,8 ± 80,9 g).Palavras-chave: Apis mellifera, abelhas selecionadas, aumento de produção Royal Jelly Production by Selected Africanized Honeybees and Carniolan HybridsABSTRACT -This study was conducted to compare royal jelly production from colonies of Apis mellifera Africanized honeybees selected for yields of royal jelly or honey with that from Carniolan hybrids. In the first trial, 10 colonies of Africanized honeybees selected for royal jelly production were used; the top five queens were replaced with their offspring and in the remaining colonies were introduced Carniolan queens in order to evaluate production after switch of population. In the second trial, 15 colonies were used as follows: five with Africanized queens selected for honey yield (AFHO), five with Africanized queens selected for royal jelly yield (AFRJ), and five with Carniolan hybrids (CAHB). In trial one, Carniolan hybrids showed greater royal jelly production/ colony/collection (3.95 ± 2.92 g) when compared to Africanized honeybees (2.23 ± 2.13 g). In addition, Carniolan hybrids had higher acceptance percentage of grafted larvae (55.4 ± 36.7) than the Africanized counterparts (35.8 ± 28.3). In trial two, yield of royal jelly/colony/collection was significantly higher on AFHO compared to AFRJ and CAHB that did not differ in production. Both Africanized honeybees (AFHO = 254.2 ± 90.7 g and AFRJ = 253.8 ± 206.8 g) produced more royal jelly per cup than CAHB that yielded 195.8 ± 80.9 g.

Quality of royal jelly produced by Africanized honeybees fed a supplemented diet

“…Another very important factor to be considered is the selection of the Africanized honeybee colonies (MOURO; TOLEDO, 2004;MOURO, 2005;FAQUINELLO et al, 2011) associated with supplementation as the key to increase royal jelly production, and quality and consequently guarantee more profits to the beekeepers too (SEREIA et al, 2010).…”

Antimicrobial Activity of Brazilian Stingless Bee Products

“…No Brasil quando se analisa a produção nacional, os produtores apresentam níveis variados de tecnologia e experiência prática, obtendo-se assim diferentes rendimentos produtivos (Martinez & Soares 2012). Alguns trabalhos indicam grande variação na produção de geleia real para abelhas A. mellifera africanizadas com médias de 188 a 234 mg/cúpula ou 1,8 a 3,96 g/coleta (Mouro & Toledo 2005;Garcia & Nogueira-Couto, (2005). Assim, trabalhos têm sido desenvolvidos no Brasil e em vários países do mundo, com a finalidade de se estudar a viabilidade da produção da geleia real como podemos observar na (Tabela 1).…”

Breeding Program Design Principles for Royal Jelly

“…Among the factors that affect royal jelly production are the internal factors of the colony, such as posture and acceptance of larvae, and external factors, such as nutrition, climate conditions, temperature, precipitation, humidity, and even genetic factors [10,34]. Toledo and Mouro [35] observed the same environmental variables and reported that the maximum external temperature and relative humidity interfered positively, i.e. increased royal jelly production, while the rainfall had a negative influence.…”

“…Sereia et al [39] concluded that the average amount of royal jelly deposited every 68 h per cup was higher when supplemented with isolated soy protein, brewer's yeast, palm oil, and linseed oil. Some studies reported variation in royal jelly production of Apis mellifera L. Africanized honeybees from 188 to 234 mg/cup [10,35,40]. Toledo and Mouro [35] stated that the amount of royal jelly obtained per cup varies with the time that is left within the colony and obtained average of 253 mg/cup for Africanized and 198 mg/cup for Carniolian honeybees.…”

Sereia et al [39] observed differences for the percentage of total acceptance of grafted larvae with a mixture of linseed oil + palm oil and isolated soy protein + brewer's yeast that had, respectively, 63.45% and 63.75% of accepted cups when compared with palm, linseed, isolated soy protein, yeast, and controls I and II (45.80%, 49.71%, 50.32%, 50.95%, 49.60%, and 52.17%, respectively).…”
