This work focuses on verifying the efficacy of the protection product Dianem (includes bioagens Heterorhabditis bacteriophora) in maize targeted against corn rootworm larvae which cause characteristic damage to stalks. The tests were initiated in April 2014 in south Moravia in three locations - Otrokovice, Čejč and Hostěradice -- in pursuance of experiments. Dianem was applied during sowing, the same way as chemical protection product Force in the chemical protection variant. The number of beetles hatched from larvae caugh in the textile cage K (untreated control), D (biologic control) and CH (chemical control) were evaluated in the tests. The evaluation took place from mid July to September in Čejč and Hostěradice where there was no statistically significant difference in the number of hatched beetles from soil in individual variants. At the end of July, goosenecks were evaluated in Otrokovice and Čejč. There was no statistically significant difference in Otrokovice between the treated and control variant. On the other hand, there was a statistically highly significant impact of Dianem in Čejč. Another part of the tests was monitoring the corn rootworm using pheromone traps Csalomon PAL.
