Characteristics of plant proteinase inhibitors and their applications in combating phytophagous insects
Plant proteinase inhibitors (PIs), which play a potent defensive role against predators and pathogens, are natural, defense-related proteins often present in seeds and induced in certain plant tissues by herbivory or wounding. This review describes the main classes of proteinase inhibitors, the distribution and localization, general properties, the main functions, and commercial applications of...
متن کاملA general model for host plant selection in phytophagous insects.
We develop a general theoretical framework for exploring the host plant selection behaviour of herbivorous insects. This model can be used to address a number of questions, including the evolution of specialists, generalists, preference hierarchies, and learning. We use our model to: (i) demonstrate the consequences of the extent to which the reproductive success of a foraging female is limited...
متن کاملPlant protease inhibitors in control of phytophagous insects
Plant proteinase inhibitors (PIs) have been well established to play a potent defensive role against predators and pathogens. Although diverse endogenous functions for these proteins has been proposed, ranging from regulators of endogenous proteinases to act as storage proteins, evidence for many of these roles is partial, or confined to isolated examples. On the other hand, many PIs have been ...
متن کاملPlant nutrient supply determines competition between phytophagous insects.
Indirect competition is often mediated by plant responses to herbivore feeding damage and is common among phytophagous insect species. Plant-mediated responses may be altered by abiotic conditions such as nutrient supply, which can affect plant growth, morphology, and the concentration of primary and secondary metabolites. Nutrient supply can be manipulated by the type and amount of fertilizer ...
متن کاملINTERSPECIFIC INTERACTIONS IN PHYTOPHAGOUS INSECTS: Competition Reexamined and Resurrected
This review reevaluates the importance of interspecific competition in the population biology of phytophagous insects and assesses factors that mediate competition. An examination of 193 pair-wise species interactions, repre senting all major feeding guilds, provided information on the occurrence, frequency, symmetry, consequences, and mechanisms of competition. Inter specific competition occ...
