Effect of the interaction between  temperature and Varroa destructor on physiological performance of Apis mellifera.

Patricia Aldea

Apis mellifera is the most important pollinator worldwide. Today, their population densities and abundance are down worldwide, registering high mortality and economic losses. This situation has become not only an environmental problem but also economic. They described various causes of these mortalities wherein the ectoparasite Varroa destructor mite has been described as the main causes. This mite enters the hive and parasitic individuals and young adults, feeding on its hemolymph, producing an overall imbalance in the hive.
Furthermore, climate change in different environments associated with global change, has become one of the greatest threats to biodiversity. This has had a direct impact on bees worldwide, and that has affected their physiological performance and changed in theory - interaction Varroa- bee. Due to the above, the aims of this research it is to evaluate the effect of Varroa on the physiological performance of bees when they are exposed to different environmental temperatures under laboratory conditions. It will also determine how the host-parasite changes (or not) relationship when the temperature conditions vary and the parasite load increases. Physiological measure and compare between treated and control groups, variables are: energy expenditure, thermoregulation behavior, feed consumption, mortality and half lethal temperature (TL50). The hemolymph components as vitellogenin, glycoprotein related to the health of individuals will also be assessed. It is expected that groups of healthy bees have less energy, greater capacity for thermoregulation, reduced feed intake, higher values of LT50 and hemolinfático healthy level of vitellogenin about groups of parasitized bees and that these physiological variables will deteriorate increasing the parasitic load on bees.
