| The Sunn Pest is the most important insect pest wheat and barley in Turkey. In order to revise the economic threshold (ET) for the pest, the average plant number, kernel number in each spike, nymphs and new-generation adults (NGAs) density, and the percent kernel damage caused by nymphs plus NGAs in per square meter were determined in wheat fields sampled. Studies were conducted in 20 insecticide-free bread and durum wheat fields which have at least 5 da. in Diyarbakir province from 2004 to 2008. The binary logistic regression was used to signify the effect of spikes, kernels, nymphs and new-generation adults (NGAs) density, and kernel damage on ET. At the end of the study, average plant per m2, kernels in each spike, over ed adult density, nymph plus new-generation adult density, and percent kernel damages were between 173.7 and 910.0 11.0 and 41.4, 0.7 and 3.7 per m², 5.7 and 114 per m², and 0.4 and 55.4%, respectively. The yield lost caused by feeding of OWAs and kernel damage due to feeding of nymph plus NGAs ranged from-89.1 to 145.3 g/m². There was no correlation between yields from sprayed and unsprayed fields. The sedimentation values were between 8 and 35, and 9 and 50 for Zeleny and incubated sedimentations, respectively. Economic damage threshold for South East Anatolia Region were around 8, 10, and 12 nymphs plus NGAs per square meter, when plant number is between 350-460 in per square meter, constant kernel number in each spike (average 26), 3.5% kernel damage tolerance limit. Hovever these numbers could be higher or lower depending on plant number, number kernels of spike … |
