Abstract
This research was carried out to evaluate the effect of proteic supplement on royal jelly production in honeybee colonies and its correlation with environmental variables. The treatments were: colonies that had received a diet formulated with 35% crude protein, colonies that had received a commercial supplement with 35% crude protein, and colonies that did not receive protein diet. There was no difference (p > 0.05) among the treatments for parameters of production. The average for each variable was: amount accepted larvae, 8.56 ± 6.76; acceptance percentage, 29.20 ± 22.03%; amount of royal jelly produced per colony, 1.83 ± 0.82 g; and amount of royal jelly produced per cup, 213.58 ± 108.36 mg. Rainfall did not affect (p > 0.05) royal jelly production. The selected models point to a negative correlation among larvae accepted with the maximum temperature and low relative humidity. Larvae acceptance and royal jelly production per cup had a positive correlation with the maximum relative humidity and negative correlation with the minimum relative humidity. It can be concluded that the addition of proteic supplement (35%) did not increase royal jelly production of Africanized honeybee colonies, and its use for this purpose was unprofitable

F values with their probabilities (P), coefficients of variation (CV%) and average of total accepted larvae per colony, acceptance of larvae grafted (% acceptance), total of royal jelly produced per colony (Rjc - g) and quantity of royal jelly deposited per cup (Rjcup - mg) in Africanized honeybee colonies in Maringá, Paraná State, from November 2000 to March 2001
O fornecimento de suplemento proteico (35%) não aumentou a quantidade de geleia real produzida por colônia
Summary
Este experimento foi realizado no período de novembro de 2000 a março de 2001, no setor de Apicultura da Fazenda Experimental de Iguatemi que pertence à Universidade Estadual de Maringá, Estado do Paraná. O método adaptado para produção de geleia real foi o de Doolittle (1899) que consiste na transferência de larvas de alvéolos de cria de operária para cúpulas artificiais de acrílico. O sistema utilizado para produção de geleia real foi o de mini-recrias composto por dois núcleos sobrepostos separados por uma tela excluídora de rainha. As larvas destinadas à transferência para produção de geleia real foram obtidas do núcleo inferior das colônias mini-recrias avaliadas no experimento. As colônias dos tratamentos 1 e 2 receberam, também, 10 g da suplementação proteica duas vezes por semana, com consumo médio de 4 a 7 g colônia-1. A cada 10 dias foi realizado manejo de quadros nas mini-recrias, trocando-se dois caixilhos com cria operculada da parte inferior por dois caixilhos de favos vazios ou com mel do ninho superior
