dc.description.abstractThe study was conducted on the cotton fields of Sehzadeler district in Manisa province with the purpose of determining some biological parameters of Helicoverpa armigera Hubner (Lepidoptera; Noctuidae) in 2018 and 2019. In both years, 5 different experimental parcels were selected to represent the cotton fields of Sehzadeler district. In 2018, cotton was sowed in 14th - 21st of April, one chemical control was applied against Aphis gossypii, Empoasca spp, and Tetranychus urticae. In 2019, cotton was sowed in 25-27 April with two different cultivars (Carisma and BA 440). A total of 7 insecticides applications were made with 5 times against A. gossypii, Empoasca spp, and Bemisia tabaci, two times against H. armigera. Adult population development of H. armigera was followed with delta and funnel traps. Samplings were made once a week, the number of adults were recorded and the number of H. armigera eggs and larvae and eggs of Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) were counted on 3 different points on 3 m plant lines in all parcels. In the first year, a total of 16 adults were captured with 2 from Karaagacli, 1 from Selimsahlar, 2 from Yenimahmudiye, 10 from Mutevelli and 1 from Veziroglu. Because of the low population density of adults, the data were not evaluated. In 2019, adult flight of H. armigera has started at the first week of July on all parcels and two peak points, in the middle of August and at the end of September, were recorded. Adult flight has continued until the harvest date (19.10.2019). A total of 434 adults were captured on all traps with 101 from Karaagacli, 83 from Selimsahlar, 55 from Yenimahmudiye, 77 from Mutevelli and 118 from Veziroglu throughout the sampling period. The highest number of H. armigera adults captured per parcel was on Karagacli and Veziroglu, which was sowed with BA 440 cultivar. On the other hand, the number of H. armigera adults captured were higher in funnel traps than delta traps in all parcels. Number of C. carnea eggs were higher than other predators on 3 m plant lines, even with 2 insecticide applications against H. armigera and other pests. A parallel trend was observed between the egg and larval population of H. armigera and the number of C. carnea eggs.
