Beet armyworm on Cabbage
Abstract
Spodoptera exigua Hübner (Lepidoptera: Noctuidae) is a multi-host serious global pest due around the world. In the current study, cabbage (Brassica oleracea L.) field populations of S. exigua were monitored in five different localities (Okara, Lahore, Faisalabad, Chiniot, and Sargodha) of Punjab, Pakistan through regular 10 days intervals on cabbage crop during 2018-2019. Results revealed the extensive distribution of S. exigua across Punjab, especially at a higher rate in Lahore Sarghoda and Faisalabad. Weather conditions (temperature and moisture) during the month of September in Punjab, Pakistan provided facilitate local population sources. Therefore, insect management protocol should be applied in the month of July, before the onset of the larval population.
