This invention discloses the application of the RAPTOR1A gene in genetic engineering to adjust plant insect resistance, as well as RAPTOR1A gene mutants and their applications, belonging to the field of plant genetic engineering technology. This invention is the first to discover that knocking out the RAPTOR1A gene can improve plant insect resistance. A tomato RAPTOR1A (NCBI gene number: 101266988) mutant was obtained using CRISPR-Cas9 technology. Slraptor1a Knockout of RAPTOR1A, a key component of the TOR complex, did not significantly alter tomato plant height, single fruit weight, or yield per plant. However, the mutant exhibited enhanced resistance to pests. Specifically, the number of eggs laid by adult tomato leafminers on the mutant plants decreased significantly, larval development slowed, and the area of ​​the leafminer feeding on the host tomato leaves was reduced. This provides a reference for subsequent breeding programs that improve insect resistance without affecting tomato yield and can be applied to the improvement of resistant tomato varieties.
