| direct and pollinator-mediated effects of herbivory on strawberry and the potential for improved resistance. | the global decline in pollinators has partly been blamed on pesticides, leading some to propose pesticide-free farming as an option to improve pollination. however, herbivores are likely to be more prevalent in pesticide-free environments, requiring knowledge of their effects on pollinators, and alternative crop protection strategies to mitigate any potential pollination reduction. strawberry leaf beetles (slb) galerucella spp. are important strawberry pests in northern europe and russia. given ... | 0 | 28572811 |
| uv-b radiation and insect herbivory: preliminary observations on strawberry plants and the leaf beetle galerucella sagittariae in finland. | enhanced uv-b (280-315 nm) radiation, as a result of stratospheric ozone depletion is known to increase uv-protective phenolics, especially flavonoids in plant tissues. we tested the hypothesis that the suitability of plant foliage to insect herbivores might be reduced due to higher amount of defence compounds produced by the host plant when exposed to enhanced uv-b radiation. strawberry plants were exposed to supplementary uv-b and uv-a radiation in an open-field exposure system. the test anima ... | 2000 | 10850003 |
| natal origin affects host preference and larval performance relationships in a tritrophic system. | many insects face the challenge to select oviposition sites in heterogeneous environments where biotic and abiotic factors can change over time. one way to deal with this complexity is to use sensory experiences made during developmental stages to locate similar habitats or hosts in which larval development can be maximized. while various studies have investigated oviposition preference and larval performance relationships in insects, they have largely overlooked that sensory experiences made du ... | 2017 | 28405274 |
