In the function of environment preservation, chemical product used in plant protection
are being substituted by environmentally friendly substances. When it comes to rodenticides
and rodents not much is done for improvement of the control of these pests on cattle
farms and in field crops facilities. A selenium based product, which for its mode of action
is more acceptable than chemical products, was investigated in this paper. Rodent death
is achieved with a single ingestion and there is no risk of intoxication of non-target organisms.
Symptoms of intoxication with this substance are not visible before the death of an
individual. The possibility of resistance development is not known as the mode of action
of this substance is based on cell death caused by switch of S-H groups in functional cells
by S-S bonds.
Experiments were conducted according to standard EPPO method. Paraffin baits in
boxes were placed at points where the greatest damage caused by rodents was observed.
For mice was used 20 g, and for rats 50-100 g. Dynamics of bait ingestion was monitored
daily and new quantities were added during the experiment. The abundance of rodents
was estimated by dividing the ratio of the minimum and maximum amounts of daily eaten
bait during the experiment by daily food needs. The presence of rodents was monitored
the following 20 days. The efficacy of tested paraffin products was calculated using
Abbott’s formula.
The efficacy of this product was compared to the fast acting products based on vitamin
D3 and to slow acting bromadiolone based anticoagulants in the experiments with
Mus musculus and Rattus norvegicus. Eco-friendly sodium-selenite based product expressed
efficacy of 87,5% for house mouse and 88,1% for the gray rat. It had higher efficacy than other
products in the experiment. Radi očuvanja životne sredine postoji težnja da se hemijska sredstva u zaštiti bilja zamenjuju
ekološki prihvatljivijim supstancama. Kad su u pitanju rodenticidi i glodari malo se čini
na unapređenju suzbijanja ovih štetočina na stočarskim farmama i ratarskim objektima.
U ovom radu ispitivan je preparat na bazi selena, koji je zbog načina delovanja prihvatljiviji
od hemijskih preparata. Efekat uginjavanja glodara postiže se jednokratnim unošenjem i
ne postoji opasnost od trovanja neciljnih organizama. Simptomi trovanja ovom supstancom
nisu vidljivi pre smrti jedinke. Nije poznata ni mogućnost razvoja rezistentnosti jer se
mehanizam delovanja ove supstance zasniva na izazivanju smrti ćelija, zamenom S-H grupa
funkcionalnih ćelija S-S vezama.
Eksperimenti su izvođeni prema standardnoj metodi EPPO. Parafinski mamci su postavljeni
u kutijama na mestima gde su primećena najveća oštećenja od glodara. Korišćeno je
za miševe 20 g, a za pacove 50-100 g. Svakodnevno je praćena dinamika unošenja mamaka
i dodavana nova količina tokom trajanja ogleda. Brojnost glodara procenjena je na osnovu
najmanje i najveće dnevno pojedene količine mamka u periodu trajanja eksperimenta i odnosa
dnevne potrebe za hranom. Prisustvo glodara je praćeno narednih 20 dana. Efikasnost
testiranih parafinskih preparata izračunata je po Abbott-ovoj formuli.
Poređena je efikasnost ovog preparata sa brzodelujućim preparatima na bazi vitamina
D3 i sporodelujućim antikoagulantima na bazi bromadiolona u eksperimentima sa Mus
musculus i Rattus norvegicus. Ekološko prihvatljivi preparat na bazi natrijum-selenita je ispoljio
efikasnost od 87,5% za kućnog miša i 88,1% za sivog pacova. Bio je efikasniji od ostalih
preparata u eksperimentu.
