Abstract:

The potato insect (Leptinotarsa decemlineata Say)(Col.:Chrysomelidae) is an egg parasitide in laboratory conditions for the purpose of exploring the biological fighting possibilities of the potato insect (Leptinotarsa decemlineata Say). and Hym.It was worked with Eulophidae. At the end of the studies, the parasitization rate in laboratory conditions was 41.6%, while the study in field conditions did not detect parasitization due to unsuitable environmental conditions (such as temperature). In addition to the study of the effectiveness of the parasitoid, preparations with Bacillus thuringiensis against the larva of harm in laboratory and field conditions have also been tested and M-ONE (B.t. There is. 500 ml/day of sandiego MYX-1806 (B.t. There is. 280 ml/day and Novodor (B.t. There is. The doses of tenebrionis 200 ml/day have been found effective.
