    Determination of Artificial Oviposition Substrates for Olive Fruit Fly, Bactrocera oleae Gmelin (Diptera: Tephritidae)
    (Univ Namik Kemal, 2008) Genc, H.
    This study was conducted to determine artificial oviposition substrates for olive fruit fly in the laboratory. Three-different oviposition substrates, paraffin mixture, parafilm and nylon were prepared and tested for their suitability as egging substrates in the laboratory. The average numbers of eggs laid by olive fruit fly were determined for each oviposition substrate. As a result, females of olive fruit flies preferred and laid the highest amount of eggs on nylon cones at 9 day-old (131.00 +/- 2.64 number/day), and the least amount of eggs laid at 18 day-old (52.00 +/- 6.35 number/day). After mating, removing of males from the cages had a negative effect in female's egg productivity. The number of laid eggs in the cages having only mated females and both males and females at 9 day-old (70.22 +/- 15.92 ve 75.77 +/- 16.84 number/day), and 18 day-old (35.44 +/- 8.72 ve 49.88 +/- 12.03 number/day) respectively. Although, olive fruit flies normally lay eggs inside the host, they also lay eggs in artificial oviposition substrates in the laboratory.

    Egg Production and Adult Longevity of The Olive Leaf Moth, Palpita Unionalis Hubner (Lepidoptera:Pyralidae) on Selected Adult Diets
    (Univ Namik Kemal, 2012) Yilmaz, C.; Genc, H.
    Survival and egg production data were collected for females of the olive leaf moth, Palpita unionalis. Adults were feed on 10% honey solution, a commercial honey bee liquid food, an orange flavored Gatorade (R), and distilled water, as a control. It was demostrated that adult diet was significantly effected olive leaf moth female longevity, the duration of oviposition periods, and fecundity. Female survival was better among those fed by honey solution, honeybee liquid food, gatorade and water then males. Egg fertility was >70% over the moths on sucrose and honey diets and fertility were not effected by adult feeding. Female fecundity was higher in 10% honey fed females as compared to the water fed females.

    The Studies on Diurnal Butterflies (Lepidoptera: Rhopalocera) in Canakkale Onsekiz Mart University Terzioglu Campus
    (Univ Namik Kemal, 2008) Zobar, D.; Genc, H.
    The purpose of the study is to determine lepidopteran species on Terzioglu Campus during March 2005-April 2007. We surveyed Rhopalocera butterflies in Canakkale Onsekiz Mart University, Terzioglu Campus, in Canakkale, Turkey. In this study, total of 44 species belonging to to Papilionidae (4), Nymphalidae (23), Pieridae (8), Lycaenidae (4) and Hesperiidae (5), were identified. The most abundant species throughout the campus are Pieris brassicae, P. rapae, P. napi, Colias crocea, Iphiclides podalirius, and Melanargia larissa.

    Vegetation indices as indicators of damage by the sunn pest (Hemiptera: Scutelleridae) to field grown wheat
    (Academic Journals, 2008) Genc, H.; Genc, L.; Turhan, H.; Smith, S. E.; Nation, J. L.
    The sunn pest, Eurygaster integriceps Put. ( Hemiptera: Scutelleridae), also known as sting or cereal pest, is one of the most economically important pests of wheat in the world. In this study, a collapsible nylon cloth cage experiments were conducted to determine the feasibility of using remote sensing techniques to detect stress in wheat caused by the density of sunn pests. The results show we can detect the amount of stress in wheat caused by different life stages of sunn pest with a hand-held radiometer. Normalized difference vegetation index (NDVI) based indices; NDVIsg, NDVId, NDVIr, and structure insensitive pigment index ( SIPI) were chosen out of 19 indices initially tested. The NDVI based vegetation indices derived from hyperspectral data, recorded by a hand held spectroradiometer, were used to determine the predicted indices using the initial number of Sunn Pest (NOSP). Overall, r(2) values of all predicted indices calculated for 3(rd) instars were lower than those of 4(th) and adult stage. When r(2) was considered separately, predicted NDVIr index value (87.4) was the highest and predicted SIPI index value is lowest (80.7) in 3(rd) instars. The highest r(2) value was obtained in adult stage of sunn pest is NDVIsg (96.9) compare with NDVId (95.5), NDVIr (92.4) and SIPI (94.2). It was also concluded that remote sensing could detect not only the different stages pest damage on wheat, but also the number of sunn pest stages density affect in controlled experiments.
