Sorghum belongs to the grass family, Gramineae. Sorghum is one of the most important fodder crops. This crop is mainly cultivated on shallow and heavy clay soils. Sorghum is attacked by different species of insects every year from its sowing till harvesting. Most important insect species of sorghum are recorded as sorghum shoot fly, sorghum midge, field earwigs, sorghum stem borer, green bugs, aphids and thrips. Sorghum also faces problem, and a decrease in terms of quality and yield every year in its growing regions, generally in Turkey and particularly in Canakkale. For the purpose to make sure the presence of different species of insects in sorghum field in Canakkale province of Turkey, a research was conducted in sorghum sowing season in the years 2000-2001 by sowing four sub varieties of two main sorghum varieties, namely sweat sorghum (M81-E and Topper-76) and sorghum sudangrass hybrid (Nutrima and Nutri honey). In this research, the insect pest population has been determined on the bases of crop harvesting in terms of maintaining different harvesting heights of sorghum crop such as 30 cm, 60 cm, 90 cm, 120 cm and 150 cm along with a control treatment (physical stage). According to the overall results of our research study, a total of 994 harmful insects were recorded in the 1st year (2000), while 2777 harmful insects were observed during the 2nd year (2001) of our study. Consequently, the larval and adult stages of sorghum shoot fly (Atherigona soccata) were present prominently in all parcels harvested with different level of heights. Moreover, M81-E and Topper-76 sub varieties of sweat sorghum were affected more and caused damage by A. soccata because of their broad leaf sheaths, thick stems and high value of nutrient contents as compared to Nutrima and Nutri honey sub varieties of sorghum sudangrass hybrid.
