Defence mechanisms of Brassicaceae: implications for plant-insect interactions and potential for integrated pest management. A review

摘要: Brassica crops are grown worldwide for oil, food and feed purposes, constitute a significant economic value due to their nutritional, medicinal, bioindustrial, biocontrol crop rotation properties. Insect pests cause enormous yield losses in production every year, threat global agriculture. In order overcome these insect pests, species themselves use multiple defence mechanisms, which can be constitutive, inducible, induced, direct or indirect depending upon the degree of attack. Firstly, we give an overview different with main focus on cultivated brassicas. Secondly, describe that attack Thirdly, address phytoalexins, sulphur, glucosinolates, glucosinolate-myrosinase system breakdown products. develop pest control strategies, it is important study chemical ecology, behaviour. We review studies oviposition regulation, multitrophic interactions involving feeding host selection behaviour parasitoids predators herbivores Regarding trophic interactions, outline behaviour, importance stimulation, oviposition-deterring pheromones, isothiocyanates, nitriles, phytoalexins towards management. Finally, brassicas as cover trap crops, biocontrol, biofumigant biocidal agents against insects pathogens. Again, emphasise products, plant volatile compounds key components processes, have been considered beneficial past hold great prospects future respect integrated
