Akutni efekat kadmijuma na rast larvi Lymantria dispar L

Dose-dependent effect of cadmium on relative growth rate (RGR) was examined in 4th instar gypsy moth (Lymantria dispar L) larvae. No-observed-effect-concentration (NOEC) was shown to be 10 mgCd/g and lowest-observed-effect-concentration (LOEC) was 30 mgCd/g dry food weight. Linear relationship was found between percentage of RGR reduction and log-transformed values of cadmium concentrations. Concentrations of cadmium that lead to 50, 75, 90 and 100% RGR reduction were calculated as 65, 195 377 and 584 mgCd/g dry food weight, respectively. Efekat različitih koncentracija kadmijuma, na relativnu brzinu rasta (RGR) ispitivan je kod larvi gubara (Lymantria dispar L) četvrtog stupnja. Pokazano je da je koncentracija koja nema vidljivi efekat (NOEC) 10 mgCd/g dok je najmanja koncentracija koja ima vidljivi efekat (LOEC) 30 mgCd/g suve težine hrane. Utvrđena je linearna zavisnost između procenta redukcije rasta i log-transformisanih vrednosti koncentracija kadmijuma. Izračunate su vrednosti kadmijuma koje dovode do redukcije rasta larvi za 50, 75, 90 i 100%, i iznose 65, 195, 377 i 584 mgCd/g suve težine hrane. null
