Bacterially expressed dsRNA induces Varroa destructor gene knockdown by honey bee-mediated oral administration por Muntaabski, Irina, Scannapieco, Alejandra Carla, Liendo, María Clara, Niz, José María, Russo, Romina Maria, Salvador, Ricardo

“…Indeed, a reduction of 50% in Varroa survival was observed when bacterially expressed dsRNAs were administered to mite-parasitized bees. Worker bees that were fed with Varroa-targeted dsRNA by oral route showed no survival differences compared to control bees, fed with sucrose or dsRNA-GFP solutions. …”

The effect of parasitism on nutrient metabolism and productivity in small ruminants. por Akinbamijo, O.O.

“…In our study, the findings with respect to the time schedule, the lower nitrogen retention and high urinary nitrogen observed in the infected ewes, are similar to those reported by Dargie and his co-workers (1979). The observed similarity in feed intake and digestibility in control and infected ewes indicate that other insidious losses must have had a major effect on the overall nitrogen retention and lower rate of weight gain in infected ewes. …”

Determination of imidacloprid in beehive samples by UHPLC-MS/MS por Michlig, Melina P., Merke, Julieta, Pacini, Adriana Cecilia, Orellano, Emanuel, Beldoménico, Horacio Ramón, Repetti, María Rosa

“…Thus, the assays were divided into four treatments and a witness (Control) with no added imidacloprid. To check the hives' exposure to imidacloprid and evaluate its distribution, sampling of adult worker bees and larvae was performed before, during and after the whole feeding period (7 weeks). …”

A spatial econometric analysis of cultural dimensions, technology knowledge and economic growth por Barboza, Gustavo A., Pede, Valerien O.

“…Initial findings indicate that differences across cultural dimensions act as a leveling effect but not as long run growth determinants. In addition, when controlling for physical and human capital accumulation, culture plays a much smaller role in explaining differences in income per capita than initially thought, with little effect on output per worker growth along the transitional dynamics path. …”
