| Abstract/Description: | Environment-friendly management of fruit flies involving pheromones is useful in reducing the undesirable pest populations responsible for decreasing the yield and the crop quality. A nanogel has been prepared from a pheromone, methyl eugenol (ME) using a low-molecular mass gelator. This was very stable at open ambient conditions and slowed down the evaporation of pheromone significantly. This enabled its easy handling and transportation without refrigeration, and reduction in the frequency of pheromone recharging in the orchard. Notably the involvement of the nano-gelled pheromone brought about an effective management of Bactrocera dorsalis, a prevalent harmful pest for a number of fruits including guava. Thus a simple, practical and low cost green chemical approach is developed that has a significant potential for crop protection, long lasting residual activity, excellent efficacy and favorable safety profiles. This makes the present invention well-suited for pest management in a variety of crops. |
| Description: | a new yet simple approach is essential which should provide viable solutions in the pest management arena. Pheromones are naturally occurring volatile semiochemicals and are considered as eco-friendly biological control agents. They induce impaired sexual communication and mating disruptions among pests. High specificity of pheromones towards a given species further enables pest control without weakening the beneficial organisms. However, due to the unstable nature of pheromones, such as photo-oxidation, auto-oxidation, isomerization and volatility etc., the formulation development for the field trials involving pheromones needs a major refinement specifically in terms of the slow-release and protection from decomposition under ambient conditions. ME in this context may be useful since it belongs to the class of a para-pheromone which mimics the role of a male attractant. Using supramolecular self-assembly principles and nanotechnology we have been able to achieve an increased shelf-life of the pheromone (ME) when immobilized in a nanogel. We demonstrate here that such pheromone nanogels exhibit high residual activity, excellent efficacy in open orchard even during adverse seasons and are also environment friendly. |
