Garlic pests have been observed on the following five study plots named Nedakonice (178 m), Olomouc (241 m), Dolni Nemci (256 m), Sucha Loz (306 m) and Vapenky (484 m) in 2010-2012. The occurrence of pests has been found out on winter varieties Dukat and Blanin using various monitoring methods during the vegetation. Most adults Oprohinus suturalis have been monitored on a variety Blanin (43.1 imagines/square m) in Dolni Nemci study plot. The adults were first detected in 2011 on 10.4. at 17.4 deg C and on 19.5. at 20.7 deg C in 2012. The first presence of O. suturalis adults did not correlate with altitude. The highest abundance of adults Lilioceris merdigera was at temperatures 18-24 deg C in dry and sunny weather. The females begin to lay at temperatures above 20 deg C, 6-12 days after the first occurrence.
