Abstract
The number of adults was monitored using a light trap type RO Agrobečej at the localities of Sombor and Begeč during 2020 and 2021. In this paper, analyzed was the correlation between that appearance frequency and the Degree day - (DD). Adults were trapped throughout the trap season from April 11th to October 19th. Altogether, five frequency peaks were recorded from June to October. Recorded peaks corresponded to DD values of 245, 457, 593, 660 and 787, respectively. The highest peak corresponded to DD value of 593. In order to get a broader picture of the appearance, DD were also calculated for 2017, 2018 and 2019. For DD 200, the mean occurrence was calculated Jun 12th, DD 245 June 18th, DD 457 July 12th , DD 593 July 28th, DD 660 August 11th and DD 787 August 17th. The distance from the mean occurrence of DD 200 on June 12th to the maximum occurrence of DD 593 on July 28th is 46 days, with a difference of DD 393. DD values from March 30th (biofix) to October 20th ranged from 951 to 1245.
