Objective
1. Capacitate graduate students (entomologists and professionals of related fields) for research in the areas of plant resistance to insects and insect-plant interactions. 2. Train students for adequate use of techniques and parameters that allow the evaluation of varieties resistance to insects as well as the identification of resistance mechanisms involved.

Content
Theoretical classes: a) Importance, History and Concepts on Host Plant Resistance; b) Constitutive and Induced Resistance; c) Parameters and Techniques for Resistance Determination: Insect Factors and Plant Factors; d) Types of Resistance: Non-preference or Antixenosis , Antibiosis and Tolerance; e) Host Selection by Phytophagous Insects; f) Causes of Resistance: Physical, Chemical and Morphological; g) Plant and Insect Factors Affecting the Resistance Manifestation; h) Environmental Effect on Resistance Manifestation; i) Use of Transgenic Plants in Pest Control, j) Plants with Insecticide Activity; k) Resistance of Plants and Pest Management.
Practical classes: There are experiments and group discussions. The experiments in minimal number of 5 are held in groups with 3 or 4 students. The subjects, which may have some variation from year to year, are basically the following: a) Effects of corn genotypes on the development of Spodoptera frugiperda; b) Resistance of corn genotypes to the weevil Sitophilus zeamais; c) Influence of defects in rice husk on the infestation of Sitophilus zeamais; d) Attractiveness of Spodoptera frugiperda to leaves of different host plants; e) Antixenosis of Eucalyptus species to Atta sexdens; f) Bioactivity evaluation of plant extracts on stored grain pests.
