Abstract
It was proven that, due to the consecutive use of the mass capturing method (12 pheromonal traps per hectare), about 1521 males of the insect Heliothis armigera have been removed – as a result, about 40% females remained unfertilized. Consequently, due to the 4 launchings of the entomophage Trichogramma evanescens 50% of the insect eggs laid on the soy plants have been infested on an average. Then, after making 7 launchings of the entomophage Bracon hebetor about 52% of the larvae of this insect have been infested. One by one, the result of using biologic agents allowed decreasing soy plant infestation up to 3% compared to 44% of infested plants in the reference variant.
