Convergence of carbohydrate-biased intake targets in caged worker honeybees fed different protein sources.
The nutritional needs of bees are supplied by nectar carbohydrates and by protein and other nutrients in pollen but little is known of how bees achieve nutritional balance. Using newly emerged caged worker honeybees (Apis mellifera scutellata), we investigated whether bees maintain their intake target when confined to pairs of imbalanced complementary diets varying in protein to carbohydrate (P...
متن کاملGrowth performance of different breed crosses of chicks fed diets with different protein and energy sources.
Six experiments (EXP) were conducted to evaluate growth performance of different breed crosses of broiler chicks fed diets containing soybean meal, soy protein isolate (SPI), soy protein concentrate (SPC), or rice and casein. Cornish x Plymouth Rock (C x PR; EXP 1, 3, 4, 5, and 6) or New Hampshire x Columbian (NH x C; EXP 2 and 4) cross chicks were used. The chicks were fed a corn-soybean meal ...
متن کاملAltruistic Behavior by Egg-Laying Worker Honeybees
If a honeybee (Apis mellifera) colony loses its queen, worker bees develop their ovaries and produce male offspring [1]. Kin selection theory predicts that the degree of altruism in queenless colonies should be reduced because the relatedness of workers to a hivemate's offspring is less in queenless colonies than it is to the daughters of the queen in queenright colonies [2-4]. To explore this ...
متن کاملQueen-signal modulation of worker pheromonal composition in honeybees.
Worker sterility in honeybees is neither absolute nor irreversible. Whether under queen or worker control, it is likely to be mediated by pheromones. Queen-specific pheromones are not exclusive to queens; workers with activated ovaries also produce them. The association between ovarian activation and queen-like pheromone occurrence suggests the latter as providing a reliable signal of reproduct...
متن کاملWorker nutrition and division of labour in honeybees
We determined whether there is an association between nutritional state (as indicated by stored abdominal lipid amounts) and division of labour in the honeybee, Apis mellifera. We found that foragers (typically older bees) had lower lipid amounts than did nurses (typically young bees). Results from experimental colonies that contained nurses and foragers of the same age showed that the lipid de...
