Host plant-driven sensory specialization in Drosophila erecta
Finding appropriate feeding and breeding sites is crucial for all insects. To fulfil this vital task, many insects rely on their sense of smell. Alterations in the habitat--or in lifestyle--should accordingly also be reflected in the olfactory system. Solid functional evidence for direct adaptations in the olfactory system is however scarce. We have, therefore, examined the sense of smell of Dr...
متن کاملHost plant specialization driven by sexual selection.
We propose a new mechanism based on sexual selection to explain the evolution of diet breadth in insects. More specifically, we show that mate choice in females for certain diet-derived male pheromones can be exploited by maternal effect genes that preferentially place offspring on a specific host plant, resulting in specialization. Our analytical model also suggests that the process is more li...
متن کاملHost plant specialization governed by facultative symbiont.
Materials and methods Samples of A. pisum were collected from natural populations on vetch or white clover, preserved in acetone, and subjected to DNA extraction individually. At each locality, 20 aphids were subjected to specific PCR detection of the endosymbionts as described (S1). The aphid strain TUt, naturally infected with PAUS, was derived from a parthenogenetic female collected on white...
متن کاملHost Plant Specialization in the Sugarcane Aphid Melanaphis sacchari
Most aphids are highly specialized on one or two related plant species and generalist species often include sympatric populations adapted to different host plants. Our aim was to test the hypothesis of the existence of host specialized lineages of the aphid Melanaphis sacchari in Reunion Island. To this end, we investigated the genetic diversity of the aphid and its association with host plants...
متن کاملHost Plant Adaptation in Drosophila mettleri Populations
The process of local adaptation creates diversity among allopatric populations, and may eventually lead to speciation. Plant-feeding insect populations that specialize on different host species provide an excellent opportunity to evaluate the causes of ecological specialization and the subsequent consequences for diversity. In this study, we used geographically separated Drosophila mettleri pop...
