Biological Control of Agricultural Pests: Innovations in RNA Interference and Transgenic Approaches for Pest Suppression

Abstract

The growing use of chemical insecticides to control pests in agriculture has caused a lot of worry about the long-term health of people and the environment, as well as the ability of pests to become resistant to these chemicals. As a result, new biological control methods are being developed. RNA interference (RNAi) and transgenic techniques are at the head of these methods for getting rid of pests. RNAi is a natural process in cells that controls gene translation. It is an exact and effective way to get rid of pest populations. Scientists can effectively get rid of pests while having little to no effect on other living things by creating small interfering RNAs (siRNAs) that target specific genes in pest species. This stops important biological processes like growth, reproduction, and survival. New biopesticides have been made possible by recent progress in RNAi technologies. These can be used directly on crops or by changing plants. The use of RNAi to control pests not only cuts down on the need for traditional poisons, but it also reduces the damage that farming does to the environment. Using RNAi along with modified crops also has positive benefits that work together to make crops more resistant to pests and lower yield losses. Pest-resistant genes are added to crop genomes using transgenic methods. This gives crops features like producing Bt (Bacillus thuringiensis) poison or being resistant to insects that eat plants. Genetically modified organisms (GMOs) like these can greatly lower the number of pests while keeping crops productive. People often don't want modified crops to be used, though, because they're worried about biodiversity, environmental balance, and possible side effects that weren't meant to happen. This paper talks about the newest RNAi and transgenic technologies for controlling pests, focused on how they work, how well they work, and what effects they have on the environment.
