Abstract
The European corn borer (ECB), Ostrinia nubilalis (Hübner) (Lepidoptera: Pyralidae) is one of the most important pest of grain corn and sweet corn in Turkey. The objective of this study was to assess percentage damage ratios of the ECB on stalk and corncobs of various sweet corn varieties in Reyhanlı district of Hatay province of Turkey.  The studies were carried out in 2015-2016 with four different sweet corn varieties including Caremelo, Vega, Merit and Batem. After two years of the study, the ECB larvae caused significant damages on stalk and corncobs of all sweet corn varieties.  The percentage damage of stalk and corncobs varied for each of the sweet corn varieties in both years.  In the first year, the highest percentages of stalk damage ratios were recorded on Batem (32.45), followed by Vega (19.85), Merit (17.07) and Caremelo (16.72).  In the second year,  the highest percentages of stalk damage ratios were observed on Merit (59.34),  followed by Caremelo (51.65),  Batem (45.09) and Vega (35.49).  In the first year, the largest percentages of corncobs damage ratios were recorded on Vega (25.73), followed by Batem (16.74), Caremelo (12.11), and Merit (9.30). In the second year,  the highest percentages of corncobs damage ratios were observed on Caremelo (14.31), followed by Merit (13.72), Batem (9.98) and Vega (8.93).  In conclusion, the largest percentages of stalk + corncobs damages ratios were observed on Batem (49.19), followed by Vega (45.58), Caremelo (28.83) and Merit (26.37) in 2015, while the highest percentages of stalk + corncobs damages ratios were recorded on Merit (73.06), followed by Caremelo (65.96), Batem (55.07) and Vega (44.42) in 2016.

Entomology and Applied Science Letters is an international double-blind peer reviewed publication which publishes scientific research & review articles related to insects that contain information of interest to a wider audience, e.g. papers bearing on the theoretical, genetic, agricultural, medical and biodiversity issues. Emphasis is also placed on the selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance. In addition to full-length research articles and reviews, the journal publishes interpretive articles in a Forum section, Short Communications, and Letters to the Editor. The journal publishes reports on all phases of medical entomology and medical acarology, including the systematics and biology of insects, acarines, and other arthropods of public health and veterinary significance.

Associations
Entomology and Applied Science Letters supports the submission of entomological papers that contain information of interest to a wider reader groups e. g. papers bearing on taxonomy, phylogeny, biodiversity, ecology, systematic, agriculture, morphology. The selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance is also important. Distinguished entomologists drawn from different parts of the world serve as honorary members of the Editorial Board. The journal encompasses all the varied aspects of entomological research.
