| ecological specialization in diaeretiella rapae (hymenoptera: braconidae: aphidiinae) on aphid species from wild and cultivated plants. | diaeretiella rapae is an aphid parasitoid with potential for use in biological control strategies. however, several recent genetic studies have challenged the long held view that it is a generalist parasitoid. we investigated its ecological specialization and ability to use resources in cultivated and uncultivated areas. ecological specialization would reduce its ability to exploit the diversity of aphid species, particularly in uncultivated areas, and to control pest aphids. four d. rapae strai ... | 2017 | 28770687 |
