Those are interesting results. Patty feeding giuves bigger worker amount than pollen cake feeding. Nutrition content must be stoger in patty stuff.
Pollen substitute diets can be effective in stimulating honey beecolonies to rear brood (Mattila and Otis, 2006; Nabors, 2000;Standifer et al., 1973), but they must be both palatable to beesand nutritious. All diets tested here with the exception of Diet- I,were similar to pollen cake in their consumption by bees.However, not all diets were equally effective in stimulating broodrearing or population growth of adult bees. Diet-2, Diet-3 andpollen were consumed at equivalent rates in both Trials. In Trial I,however, significantly more brood was reared and there werelarger adult populations in colonies fed Diet-3 patties comparedwith those fed the other diets. These results suggest thatdifferences in the nutritional quality of the diets (i.e., amounts ofprotein and carbohydrate) and perhaps the digestibility andaccessibility of their nutrients to worker bees influence theamount of brood that can be reared even when consumptionrates are similar.
In addition to nutritional
