Onion thrips, Thrips tabaci (L) is a key pest of onion and their control is vital to the production and profitability of this crop. If onion thrips are
not controlled, damage can routinely reduce bulb yields by 23-85%. Most onion fields need protection against thrips for two to three months and
multiple applications are required to control infestations, but there are few labeled insecticides that provide effective and consistent control.
Therefore, the present study was conducted in two locations viz. Ambo and Guder, Western Shewa of Oromia Regional state, Ethiopia. A
factorial experiment was laid out in randomized complete block design with three replications to evaluate the effect of insecticides (Cutter 112
E.C TM and Triger 5% E.CTM) and botanicals (Azadirachta indica L. and Dodonae angustifolia L.) on onion thrips on farmers cultivated filed. The
results of the study revealed that the newly introduced both insecticides gave promising mortality rate and not significantly (P
