Social encapsulation of the small hive beetle (Aethina tumida Murray) by European honeybees (Apis mellifera L.)Springer Science and Business Media LLC - Tập 50 - Trang 286-291 - 2003

European and African subspecies of honeybees (Apis mellifera L.) utilize social encapsulation to contain the small hive beetle (Aethina tumida Murray), a honeybee colony scavenger. Using social encapsulation, African honeybees successfully limit beetle reproduction that can devastate host colonies. In sharp contrast, European honeybees often fail to contain beetles, possibly because their social e...... hiện toàn bộ
Plasticity in expression of fruit fly larval feeding clusters in response to changes in food quality and distributionSpringer Science and Business Media LLC - - Trang 1-11 - 2024

Joining a social group entails a range of possible costs and benefits, with the balance of pros and cons potentially dependent on the specific conditions present in the local environment. In the third-instar stage of fruit fly (Drosophila melanogaster) development, individuals may join together into clusters that can increase access to buried food resources, but this collaboration comes with the p...... hiện toàn bộ
Workers and queens of the European hornetVespa crabro L. have colony-specific cuticular hydrocarbon profiles (Hymenoptera: Vespidae)Springer Science and Business Media LLC - Tập 42 - Trang 45-55 - 1995
D. P. Butts, M. A. Camann, K. E. Espelie
Cuticular hydrocarbons were extracted from sixty individual workers from six colonies ofVespa crabro L. and analyzed by combined gas-chromatography/mass spectrometry. Discriminant analysis of the cuticular hydrocarbon profiles of workers and queens showed that the wasps could be grouped by colony and by caste. Stepwise discriminant analysis selected the components which were weighted most heavily ...... hiện toàn bộ
Warmer mid-day temperatures increase leaf intake by increasing forager speed and success in Atta colombica during the rainy seasonSpringer Science and Business Media LLC - Tập 67 Số 2 - Trang 213-219 - 2020
Welch, L. E., Baudier, K. M., Harrison, J. F.
Predicting the effects of climatic warming on social insects remains an important challenge. While warming is known to speed many rate processes, the acute effects of temperature on performance under field conditions remain poorly studied. The effects of temperature are usually nonlinear, and tropical animals have been predicted to be particularly likely to be negatively affected by global warming...... hiện toàn bộ
