The invasive human population needs the event of latest agricultural technologies to satisfy consumers´ demand and minimizing environmental impacts. Insect pests area unit one amongst the most causes for losses in agriculture production, and current management technologies supported chemical application or the employment of transgenic crops expressing true bacteria thuringiensis toxin proteins are facing efficacy challenges. So there is an urgent need to take up novel approaches to control the pests. So RNA interference (RNAi)is one such new generation approach made which is a gene silencing mechanism triggered by providing double-stranded RNA (dsRNA), that when ingested into insects can lead to death or affect the viability of the target pest and this process basically relies on plants stably expressing double-stranded RNAs (dsRNAs) that target essential genes in pest insects. Recent studies have shown that plant-mediated RNA interference (RNAi) shows great potential in crop protection. A better understanding of the mechanisms that verify the variability within the sensitivity of insects would accelerate the worldwide unleash of business RNAi-based approaches. The purpose of this review article is to discuss in detail the mechanism of RNAi which can help in the pest control Management and also the environmental with biosafety issues concerned within the use of this technology in agriculture .
