Efficacy of avermectins, diamides and neonicotinoids in control of codling moth (Cydia pomonella L.) In apple orchards

Abstract

Using standard EPPO method, field trials were conducted in 2013, in order to investigate the efficacy of avermectin, diamide and neonicotinoid insecticides in codling moth (Cydia pomonella) control. The results of the field trials at the localities of Radmilovac and Vinča indicated high efficacy of combination of emamectin benzoate and mineral oil (96.2-100%) in the control of C. pomonella in apple orchards. At the locality of Vinča, high efficacy (94.9% and 95.6%) was achieved by using chlorantraniliprole and cyantraniliprole, but these compounds were slightly less effective (92.5%, and 92.0%) in control of codling moth, at the locality of Radmilovac. The efficacy of thiacloprid was poor (82.8% - 85.7%) at both localities, but this compound was more efficient at the locality of Vinča where the intensity of infestation in untreated plots was low. The efficacy of acetamiprid was very poor (54.6%-55.1%) in control of this pest, at both localities.

Tokom 2013. godine ispitana je efikasnost insekticida iz grupa avermektina, diamida i neonikotinoida u suzbijanju jabukovog smotavca (Cydia pomonella L.), izvođenjem poljskih ogleda, a u skladu sa standardnom EPPO metodom. Rezultati ovih ogleda, na lokalitetima Radmilovac i Vinča, ukazali su na dobru efikasnost kombinacije emamektin benzoata i mineralnog ulja (96,2-100%) u suzbijanju C. pomonella u zasadu jabuke. Dobra efikasnost (94,9% i 95,6%) na lokalitetu Vinča postignuta je primenom hlorantraniliprola i cijantraniliprola, pri čemu su ova jedinjenja imala nešto niži stepen efikasnosti (92,5%, odnosno 92,0%) u suzbijanju jabukovog smotavca na lokalitetu Radmilovac. Slabiju efikasnost (82,8%-85,7%) na oba lokaliteta ispoljio je tiakloprid, pri čemu je bio efikasniji na lokalitetu Vinča, gde je intenzitet infestacije u kontroli bio niži. Veoma slabu efikasnost u suzbijanju ove štetočine jabuke imao je acetamiprid (54,6%-55,1%) na oba lokaliteta.
