Insect Population Response to Mixed and Uniform Plantings of Resistant and Susceptible Plant Material

Mechanisms of resistance to the flea beetle, Phyllotreta cruciferae (Goeze), in mustard seedlings, Sinapis alba L.

“…On the other hand, yellow mustard (sinapis alba L.) grown under the same conditions as canola and exposed to the same density of flea beetles shows a high level of resistance to damage (Putnam 1977;Lamb 1984). Painter (1951) (Overman and MacCarter 1972;Cantelo and Sanford 1984). In other cases nonpreference was more apparent in solitary stands (Cantelo and Sanford 1984) while in other systems choice and no-choice experiments gave essentially the same information (Goonewardene etal.…”

Agricultural Biodiversity Is Essential for a Sustainable Improvement in Food and Nutrition Security

“…The use of biodiversity to mitigate damage by pests and macro-parasites is not as well documented as its use against diseases, although Gurr et al [58] listed several examples that range in scale from the very local-harvesting lucerne fields in alternating strips preserves structural diversity and habitat for natural enemies of Helicoverpa spp-to the landscape-parasitism rates on armyworm Pseudaletia unipuncta are higher in more complex landscapes (see [59,60] for additional examples). Nevertheless, there is a long tradition of integrated pest management (IPM) in which biodiversity plays a central role, although more often in the context of promoting a diverse population of predators than in the use of host biodiversity specifically to mitigate the impact of pests (see, for example, [61]).…”

Genomics Meets Biodiversity: Advances in Molecular Marker Development and Their Applications in Plant Genetic Diversity Assessment

“…Research programs that aim to investigate population structure provide evolutionary insights into the demographic patterns of diverse organisms . Interest in genetic diversity has also risen in applied fields of biology such as agriculture, where the technique of multiline sowing of varietal mixes within a single field has long been known to increase crop yields (Smithson & Lenne, 1996) and to decrease damage by pests and pathogens (Cantelo & Sanford, 1984). In some crops (e.g.…”
