Host plant resistance (HPR) is a crucial strategy in integrated pest management, focusing on developing crop varieties that can resist or tolerate insect pests. Several mechanisms contribute to the resistance of host plants, which can be broadly classified into antixenosis, antibiosis, and tolerance. Antixenosis refers to plant characteristics that deter insects from attacking or feeding on the plant. These traits may include physical features such as leaf hairiness, waxiness, or thick cuticles, which can make it more difficult for insects to land on or feed from the plant. Some plants also produce volatile chemicals that repel pests or attract natural enemies of the pests. These plants are typically not preferred by insects for feeding, oviposition, or settling, reducing the initial attack and infestation.
