Abstract
A broad understanding of the various level of interaction taking place between plants – herbivores and their natural enemies is very much important for the development of biological control methods which not only yields fruitful results in pest suppression but also encourage the abundance and effectiveness of entomophagous insect guild in natural ecosystem. The use of allelochemicals to manipulate entomophagous insects and to improve their performance in cropping systems holds great promise for biological control programmes and integrated pest management strategies. Therefore, sufficient data on crop wise study on tritrophic interactions may even enable us to have resistant crops with allelochemicals. These chemicals increase entomophagous insect activity leading to the co-existence of chemical resistance of host plants and biological control. Therefore, tritrophic studies involving host plant, herbivore and natural enemy interactions are important and could give rise to significant advances in future biological control programmes and integrated pest management strategies.
