The study conducted at the Agricultural Research Station / Kirkuk University during the agricultural season 2017 – 2018 to study the sensitivity of different onion varieties to Thrips Onion insects (Thrips tabaci).

Where eight local varieties were used ,the experiment was organized with the system of complete random sector R.C.B.D and with three replications where the percentage of infect different Onion varieties with Thrips Onion insects (Thrips tabaci) and study the numerical density of Thrips Onion in two methods, the first method is direct counting on the plant and the seconf method is colored traps, .

The results summarized that Pevaz Sor (V4) var.

was significant increase with the highest rate of infect with Thrips Onion that reached 33.90% followed by the Baasheqi (V6) var.

31.59% and the least sensitive varieties was Pevaz Spi (V1) 26.98%, as for the numerical density.

The direct count method showed different significant in the number of Thrips where the lowest numbers are recorded on the Diralok (V3) var., followed by Peazy Pevaz (V8) var.

and Canicomany (V5) var.

where it reached 22.67, 23.41, 23.91 Thrips / Plant respectively, and the Pevaz Sor (V4) was significant increase in recording the highest numbers of the insect during the season, were it reached 32.61 Thrips / Plant / Week.

The second method is the method of colored traps the results showed there were no significant different between the blue and yellow traps, the overall rate of the insect caught during the season on the yellow traps which was (2.75 Insect / Trap ) ,direct count and colored traps, the direct count overtook in terms of its proficiency in estimating the number of Thrips Compared with colored traps method.
