This study discusses promising methods of biological control of the main corn pests, based on the integrated use of pheromones, entomopathogenic preparations and the release of parasitic hymenoptera Trichogramma evanescens West. and Habrobracon hebetor Say. Seasonal dynamics of flying and the number of cotton moth Helicoverpa armigera Hbn. and Kuban click beetle Agriotes tauricus Heyd. were determined by capturing males with pheromone traps. Species composition of corn pests, the dynamics of flying and the number of dominant pests of the cotton moth H. armigera and corn moth Os. nubilalis are determined, the optimal dates for protective measures (release of entomophages - Trichogramma and Habrobracon, treatment with biological products) are set. As a result of the field assessment of the biological control system of the main corn pests, we determined the satisfactory efficacy of the mutually suppressing techniques based on using Trichogramma and Habrobracon entomophages and biological preparations based on entomopathogenic bacteria and viruses. The corn bioprotection efficacy against the stem corn moth was 84 % in the early hybrid and 94 % in the late one, against the cotton moth – 82,2 - 77,8 %, respectively.

Eighteen corn cultivars were tested for resistance to three corn pests (corn earworm, sugarcane borer, and corn silk maggot), and two diseases (corn rust and corn blight) at Mayagüez, Puerto Rico. Armyworm control with methomyl was necessary to produce a corn crop. Eighteen cultivars from Georgia were less resistant to pests and diseases than Mayorbela, Ibadan A, and Ibadan B. Significant differences were found between sprayed and unsprayed plots in yield and pest infestation.
