Abstract

4 Saban GUCLU 5 Summary Determination of population changes of Laodelphax striatellus (Fallen, 1826) and Sogatella vibix (Haupt, 1927) (Hemiptera: Delphacidae) by using different sampling methods in second crop maize in Diyarbakir province The aim of present study was to investigate population changes of Laodelphax striatellus (Fallen, 1826) and Sogatella vibix (Haupt, 1927) Delphacidae (Hemiptera) by using yellow sticky traps and D-Vac in second crop maize fields of Diyarbakir province in 2005 and 2006. The first individuals of L. striatellus were recorded in the traps in early july and its higher densities were caught in yellow sticky traps than that of D-Vac. Similarly, S. vibix individuals were first seen in the middle of july, while its highest densities were caught by both traps in august. Mean numbers of L. striatellus and S. vibix were significantly changed by the years of study, sampling weeks, sampling fields and the sampling methods utilized. However, population densities of L. striatellus were not different between two locations in contrast to S. vibix population.
