Influence of Neonicotinoids on Selected Characteristics of the Earthworm Dendrobaena Veneta (Rosa) in Laboratory Conditions

Vol. 20, nr 4

217--224

In the laboratory experiment, the effect of neonicotinoid Nuprid 200SC at the dose recommended by the manufacturer on the dynamics of population of earthworms Dendrobaena veneta was assessed. The studies were conducted on mature D. veneta specimens, in 4 replications of beddings (control, insecticide) in the climatic chamber. Condition of the population was checked five times, using a method of manual segregation of beddings. Insecticide limited the increase in number and biomass of D. veneta population (both the whole population, mature specimens and immature earthworms), but also restricted its reproduction (it decreased the number of cocoons laid by earthworms (p<0.05)).
