   Sammanfattning : Agriculture has received renewed attention in poverty reduction efforts in Africa in recent years, and there are hopes that GM crops could have an important role in helping increase smallholder yields and reduce poverty. Drawing on critical discourse analysis (CDA) and livelihoods perspectives, this thesis examines the ideas governing the Massive Food Production Programme (MFPP), an agricultural development programme aiming to reduce poverty by raising agricultural production in Eastern Cape Province, South Africa, and its local effects when implemented in smallholder communities.

   Sammanfattning : The social organization of social insect colonies can be broadly defined as monogynous, single reproductive female or polygynous, several reproductive females. Monogynous organization is genetically simple while polygynous is more complex and the two social forms differ commonly in mating and dispersal behaviour as well as in colony foundation. LÄS MER

   Sammanfattning : Odors are essential in mediating insect reproductive behavior. Environmental odors help insects locate suitable feeding or egg-laying sites and avoid suboptimal hosts or dangerous habitats. Sex pheromones, on the other hand, are responsible for mate finding and elicit courtship and mating. LÄS MER
