Onion thrips (Thrips tabaci) has become important pest in onion crops in Transnistria. Because it is a polyphagous species, it causes damage also in vegetable production in general (leek, cabbage, ornamentals etc.). The group of efficient insecticides for thrips control in Transnistria is limited, because its misusage in the past caused the development of resistance of this pest. In 2016-2017, different insecticides based on seven active substances was tested in Transnistria institute. The results of field experiments showed the highest efficiency of active substances Cyantraniliprol and Spirotetramat for control of Thrips tabaci. Unfortunately, they are not registrated in Transnistria for this purpose as yet.
