Chili Pepper Jojutla Morelos ( L.), CJ-2018: A Variety Resistant to .

Chili pepper is a vegetable of worldwide economic and gastronomic importance. The psyllid, , is an economically important pest in this crop, causing considerable losses in its production. Currently, the application of insecticides is the main way to control . However, the use of varieties resistant to this insect is a viable alternative for its control and management. In this work, the oviposition rate, development, and survival of in two native varieties of chili were evaluated. Choice and non-choice trials showed that the oviposition was reduced on CJ-2018 by 92.17 and 80.18%, respectively, compared to the control. In CM-334, the insect showed a behavior similar to the control in the non-choice test, while in the choice test it laid more eggs on CM-334 compared to the control. The development and survival assay showed that only 1.33% of the eggs managed to reach the adult stage on CJ-2018. In contrast, on CM-334 the survival of was similar to the control. These results suggest that CJ-2018 presented a resistance based on antixenosis and antibiosis against .
