Rearing Africanized honey bee (Apis mellifera L.) brood under laboratory conditions
(FUNPEC-EDITORA, 2009)
We developed a method for rearing larvae of Africanized bees under laboratory conditions to determine the amount of diet needed during larval development to obtain a worker bee. We started with larvae 18-24 h old, which ...
Effect of pelleting and pellet size of a concentrate for intensively reared beef cattle on in vitro fermentation by two different approaches
(Elsevier B.V., 2010-08-11)
Two in vitro experiments were performed to evaluate the effect of concentrate pelleting for intensively reared cattle on rumen microbial fermentation. In Experiment 1, a concentrate was incubated as meal (M) or pelleted ...

What is the most suitable native bee species from the Neotropical region to be proposed as model-organism for toxicity tests during the larval phase?
(2020-10-01)
Currently, Brazil has a full framework for pesticide risk assessment established for Apis mellifera, based on the North American approach. However, the use of Apis mellifera as model-organism as a surrogate for Brazilian ...
Differences in pre-imaginal development of the honey bee Apis mellifera between in vitro and in-hive contexts
(EDP Sciences, 2020-10)
In vitro rearing of honey bees is becoming a widely employed procedure. Nevertheless, few studies have assessed its impact on brood development considering nutritional and social differences between both in vitro and in-hive ...
Larvae of stingless bee Scaptotrigona bipunctata exposed to organophosphorus pesticide develop into lighter, smaller and deformed adult workers
(Elsevier B.V., 2021-03-01)
Organophosphorus pesticides such as chlorpyrifos are often used in agriculture due to their broad spectrum of action. However, this insecticide and acaricide is considered highly toxic to the environment and can cause ...
In vitro larval rearing protocol for the stingless bee species Melipona scutellaris for toxicological studies
(2019-03-01)
Brazil has the highest biodiversity of native stingless bees in the world. However, Brazilian regulations are based on protocols standardized by the Organization for Economic Cooperation and Development (OECD), which uses ...
