Full textProducing package bees (adult bees and a young queen) and nuclei (small colonies, each with brood, adult bees and a young queen) is one strategy for establishing new colonies and replacing those that are weak or dead. Although beekeepers around the world commonly engage in this work using various methods, scientific literature on the subject is scarce. In Canada, there is a growing need to replace and increase colony numbers to satisfy the demand for pollination services and compensate for high winter colony mortality. The main objective of our study was to develop a methodology for producing new colonies that is both more structured and better adapted to the challenges facing today’s Canadian beekeeping industry. One package bee and two nuclei-making techniques were compared at the Deschambault Research Center for Animal Sciences in 2014: A) 1 kg of adult bees + young mated queen, B) one brood frame + adult bees covering frames + young mated queen, C) two brood frames + adult bees to covering frames + young mated queen. In total, 38 new colonies were produced. These colonies were monitored from July 2014 to June 2015, measuring a set of parameters designed to evaluate their strength as well as levels of varroa mite infestation and nosema disease infection. Results showed no significant statistical differences in the development of these colonies. However, the findings confirm that technique B) represents the best multiplication potential and that retrieving bees or brood in hives for making nuclei controls both varroa mite infestations and swarming.

Full textThe small hive beetle (SHB), Aethina tumida Murray, is an invasive pest of honey bees, Apis mellifera L., recently introduced in Canada. The economic loss that would result from SHB spreading across the country is significant. SHB phenology has been poorly studied under temperate climates. Moreover, traps for monitoring and capturing this pest have never been tested in Canada. This project had two main objectives: 1) to determine the effects of temperature and water content of soil on the survivorship and development time of SHB pupa; and 2) to determine the effectiveness of three models of in-hive traps as well as their impact on colony productivity. Results shown that wet soils decreased survival rate by half and influenced sex ratio of emerging adults, while dryer soils increased duration of pupation by several days. The in-hive traps tested effectively reduced SHB population without affecting colony productivity. This study contributes to a better understanding of the phenology of the SHB in temperate climates and provides new knowledge to inform appropriate use of available control methods.
Szczepanski, Nicolas. "SAT en Parallèle." Thesis, Artois, 2017. http://www.theses.fr/2017ARTO0403/document.
Full textThis thesis deals with propositional satisfiability (SAT) in a massively parallel setting. The SAT problem is widely used for solving several combinatorial problems (e.g. formal verification of hardware and software, bioinformatics, cryptography, planning, scheduling, etc.). The first contribution of this thesis concerns the design of efficient algorithms based on the approaches « portfolio » and « divide and conquer ». Secondly, an adaptation of several parallel programming models including hybrid (parallel and distributed computing) to SAT is proposed. This work has led to several contributions to international conferences and highly competitive distributed SAT solvers
