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. |
