“…Earlier studies have shown that performance of phytophagous insects is determined in large part by concentrations of various mineral elements in host plants and by their ratios to one another (Clancy et al 1988, Clancy 1992, Clancy and King 1993, Busch and Phelan 1999, Beanland et al 2003. Phelan et al (1996) and Phelan (1997) suggested that plants grown on organically amended soils have a more optimal mineral balance than plants grown on synthetically fertilized soils.…”

“…In 60% of studies, herbivore populations increased at higher nitrogen additions, yet no effect or negative responses were observed in the other 40%. Recent work suggests that the ratios of nutrients can have stronger effects on herbivores than individual nutrient levels (Busch & Phelan 1999;Beanland et al 2003).…”

This paper discusses biotic interactions in agroecosystems and how they may be manipulated to support crop productivity and environmental health by provision of ecosystem services such as weed, pest and disease management, nutrient cycling and biodiversity conservation. Important elements for understanding biotic interactions include consideration of the effects of diversity, species composition and food web structure on ecosystem processes; the impacts of timing, frequency and intensity of disturbance; and the importance of multitrophic interactions. All of these elements need to be considered at multiple scales that depend in part on the range of the movement of the organisms involved. These issues are first discussed in general, followed by an examination of the application of these concepts in agricultural management. The potential for a greater use of ecological management approaches is high; however, owing to the nature of complex interactions in ecosystems, there is some inherent unpredictability about responses to management interventions under different conditions. Such uncertainty needs to be accommodated in the development of recommendations for farm management. This requires an increased emphasis on the effective synthesis of complex and often apparently contradictory information and on field-based adaptive research, monitoring and social learning by farmer/researcher collaborations.

“…We found no earlier studies conducted with woody plants wherein the effects of B on their resistance to herbivores were investigated. However, in a study conducted with annual soybean plants, B fertilization increased the resistance of the plants, such that the weights of soybean looper pupae, velvetbean larvae, and Mexican bean beetles were lowered (Beanland et al, 2003). The smallest insects also were produced on plants that received an optimal B:Fe:Zn -ratio for the growth of the plants (Beanland et al, 2003); this suggests that an optimal balance to the nutrition of plants may play a role in their defense against insect herbivores (see Phelan, 1996).…”

“…Boron deficiency could increase resistance via an enhanced production and oxidation of phenols. However, fertilization with B has been shown to improve plants' resistance to pathogens (Dordas, 2008), and optimal B nutrition improved the resistance of soybean to herbivores (Beanland et al, 2003). According to the mineral balance hypothesis, optimal balance among minerals enhances plants growth and improves their herbivore resistance (Phelan et al, 1996).…”

Boron Fertilization Enhances the Induced Defense of Silver Birch

Boron (B) deficiency is a common micronutrient deficiency that has been reported to affect the phenolic metabolism of plants. Thus, it may play a role in defense against herbivorous animals. However, the role of B in a plant's resistance to herbivores has not received any particular attention from researchers. In this study, we tested the effects of B nutrition 1) on the biochemical and mechanical defenses of birches and the growth of seedlings, and 2) the resistance of seedlings to larvae of the autumnal moth, Epirrita autumnata. Boron fertilization improved the resistance of birch, which was shown as reduced pupal weight of the herbivore. However, B fertilized trees suffered from heavier defoliation than unfertilized ones due to compensation feeding of larvae. The growth of the seedlings was diminished, and several biochemical changes occurred in leaves of herbivore seedlings, and B also played a role in these changes. Polyphenoloxidases (PPOs) and peroxidases (PODs) and their substrates, chlorogenic acids, were induced by herbivory in B fertilized seedlings but not in unfertilized seedlings. The lower pupal weights and increased consumption of the herbivores were probably linked to the plants' phenoloxidase-mediated production of reactive quinones, which decrease the nutritive value. Herbivory upon new stems led to an increase in the number of resin glands that provide defense against mammalian herbivores. Herbivory also had a substantially negative effect on B concentration in leaves of B fertilized seedlings. We postulate that B nutrition of trees may play a significant role in the induced defense of birches.
