First report of Chilo partellus in Turkey, a new invasive maize pest for Europe
2016
Bayram, A. | Tonğa, A.
The spotted stem borer, Chilo partellus (Swinhoe, 1885) (Lepidoptera: Crambidae), an invasive pest of wild and cultivated grasses in Asia and Africa, was found for the first time during periodic surveys of maize fields in the East Mediterranean region of Turkey in September and October 2014. The pest was recorded in maize fields of three of four provinces surveyed (Adana, Hatay and Osmaniye; it was not detected in Icel province). The Mediterranean corn stalk borer, Sesamia nonagrioides Lefebvre (Lepidoptera: Noctuidae), is the dominant maize pest in the East Mediterranean region of Turkey, followed by the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae). The new invasive species comprised 4.9% of the total number of collected lepidopteran pests collected from maize stems and cobs in locations infested by C. partellus. No natural enemies of the new pest were recorded during our surveys. We discuss possible interactions among these three lepidopteran pests sharing the same habitat, prospects for control of C. partellus by the control methods currently used against S. nonagrioides and O. nubilalis, and also speculate on the path of invasion taken by C. partellus into Turkey.
