    Bitlis, Muş ve Van illeri lahana ekim alanlarındaki zararlı ve faydalı böcek türleri, önemli zararlı ve faydalı türün popülasyon değişiminin belirlenmesi
    (Osman SAĞDIÇ, 2021) Ölmez, Mustafa; Sertkaya, Erdal; Buyuk, Musa; Alaserhat, İsmail
    Bu çalışma Bitlis, Muş ve Van illeri lahana alanlarında parazitoit, predatör ve zararlı olan böcek türlerinin belirlenmesi, bu türlerden ana zararlı tür ve parazitoitinin popülasyon gelişiminin belirlenmesi amacıyla yürütülmüştür. Çalışmaların 2017 yılında Bitlis Ahlat, Adilcevaz, Muş Merkez ve Korkut, Van Erciş ilçelerindeki lahana alanlarında tür teşhis çalışmaları, 2018-2019 yılları arasında Bitlis Adilcevaz ve Ahlat ilçelerinde Pieris brassicae (L.) ve parazitoiti Cotesia glomerata L.’nın popülasyon takibi yapılmıştır. Pieris brassicae’nın ergin takibinde atrap metodu, larva popülasyonu takibinde ise gözle kontrol metodu kullanılmıştır. Larva parazitoiti C. glomerata’nın popülasyon takibinde yalnızca atrap metodu kullanılmıştır. Yapılan sürveyler sonucunda 4 takım 12 familya da 21 zararlı tür belirlenmiş. bunlardan Pieris rapae L., P. brassicae (Lepidoptera: Pieridae) [lahana Kelebeği], Hellula undalis (Fabricius) (Lepidoptera: Pyralidae) [lahana göbekkurdu], Plutella xylostella L., (Lep.:Yponomeutidae)[lahana yaprak güvesi], Aleyrodes proletella L. (Hemiptera: Aleyrodidae), [lahana beyaz sineği], Spodoptera littoralis (Bois.) (Lepidoptera: Noctuidae) [pamuk yaprakkurdu] başlıca önemli zarar türler olarak görülmüştür. Ayrıca 1 takıma ait 2 familyada 8 parazitoit ve 5 takıma ait 8 familyada 12 predatör tür tespit edilmiştir. Parazitoitlerden en fazla sayıda C. glomerata (Hym.:Braconidae) ve Hyposoter ebeninus Grav. (Hymenoptera: Ichneumonidae), predatörlerden Polistes gallicus (L.) (Hymenoptera: Vespidae) belirlenmiştir. Pieris brassicae’nın çalışmanın yapıldığı yıllarda ve lokasyonlarda C. glomerata ile aynı dönemlerde görülmeye başlandığı, popülasyonunun yüksek olduğu aylarda parazitoitinin yoğunluğunun da yükseldiği belirlenmiştir. Yıllar itibarı ile değişmekle birlikte P. brassicae’nın nisanın III. haftası ile ekimin III. haftasına kadar olan sürede doğada larvalarının bulunduğu ve larvaların 17 Ağustos 2018’de en yüksek yoğunluğa (10 adet larva/bitki) ulaştığı saptanmıştır. Larva parazitoiti, C. glomerata erginlerinin ise haziran ayının ikinci haftası ile ağustos ayının sonuna kadar doğada bulunduğu ve en yüksek yoğunluğa (40-39 birey/50 atrap) 2018 yılında ulaştığı belirlenmiştir.

    Chalky spot damage caused by stink bugs on red lentil seeds in Southeast Anatolia Region, Turkey
    (Agricultural Research Communication Centre, 2016) Mutlu, Cetin; Karaca, Vedat; Eren, Sedat; Buyuk, Musa; Gozuacik, Celalettin; Duman, Mehmet; Bayram, Yunus
    Chalky spot damage on red lentil is the most important. problem waiting for a solution regarding plant health at lentil cultivation. in. Southeast Anatolia Region, Turkey. The stink bugs, Piezedorus lituratus (F.) and Dolycorus baccarum L. were subjected to trialsincages and in sprayed and unsprayed plot trials in open lentil fields and fields containing windrowed lentils after harvesting. The study revealed that P lituratus and D. baccarum feeding on red lentil caused chalky spot damage: Average damage,to lentil seeds caused by P lituratus, was 13% and 7.8% and by D. baccarum was 4.9% and 2% in 2010 and 2011, respectively. There was a positive relation between P. lituratus density and chalky spot damage.(r =0.788; r(2) =0.621, P=0.000). The study also showed that after the harvesting, the stink bugs gathered under windrowed lentils and continued feeding and causing chalky spot damage. The damage in unsprayed windrowed lentils (6.60%) was approximately 12-fold higher than that in sprayed windrowed lentils (0.57%). Study suggests conduction of future work on environmental friendly control methods of stink bugs and alternative harvesting methods.

    Determination of Susceptibility Levels of Helicoverpa armigera (Hubner) (Noctuidae: Lepidoptera) Strains Collected from Different Regions to Some Insecticides in Turkey
    (Gazi Entomological Research Soc, 2013) Ugurlu Karaagac, Sakine; Konus, Metin; Buyuk, Musa
    Cotton bollworm, Helicoverpa armigera, is the main insect pest of cotton plant in Turkey and most part of the world. The aims of this study was to determine susceptibility levels of Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) strains collected from cotton fields in Adana and Mardin provinces to registered seven insecticides in Turkey. Third instar larvae of H. armigera were used to determine the LD50 values by using topical application method with active substances of commonly used insecticides for controlling H. armigera in cotton fields. The active substances were azinphos-methyl, bifenthrin, beta-cyfluthrin, esfenvalerate, indoxacarb, lambda-cyhalothrin and methomyl. Insects were treated on the region of the body between the head and the abdomen, thorax, with 1 mu l aliquots of insecticides in acetone for all treatments and acetone alone for control. Results showed that Adana and Mardin strains had high resistance ratios to pyrethroid insecticides such as beta-cyfluthrin, bifenthrin and esfenvalerate, whereas they did not have significant resistance for indoxacarb and methomyl. These results can be used in the resistance management programs for the control of H. armigera in the region.

    EFFICIENCY OF PHEROMONE WATER TRAPS AND LIFE CYCLE OF TUTA ABSOLUTA (LEPIDOPTERA: GELECHIIDAE) IN DIYARBAKIR PROVINCE, TURKEY
    (Parlar Scientific Publications (P S P), 2017) Bayram, Yunus; Duman, Mehmet; Buyuk, Musa; Mutlu, Cetin
    The first detection of Tomato leaf miner, [(Tuta absoluta) (Meyrick, 1917) (Lepidoptera: Gelechiidae)] in Turkey was in 2009 and it rapidly spread and became the major pest in the areas where tomato is cultivated, including Southeastern Anatolia Region of Turkey. The aim of this study was to investigate the infestation status, life cycle and efficiency of pheromone water traps of Tomato leaf miner in Diyarbakir province, Turkey. The studies were conducted in farmers' fields and Diyarbakir Plant Protection Research Institute trial field between 2011-2013 years. Tomato leaf miners were subjected to trials in cages and the pheromone water traps were used for biotechnical control at open tomato fields. The infestation rate of T. absoluta was low in seedling stage and during ripening period of fruit and the infestation rate reached up to 100% and continued until the harvest in both years in the Central and Bismil districts of Diyarbakir. The pheromone water traps were not sufficient to control T. absoluta in spite of a large number of males caught. Adults of T. absoluta flying were recorded during at the end of March (8-12 degrees C and 62-75% relative humidity). Five generations were determined for T. absoluta with an average of 40 days for each generation and it was affected by extremely high temperatures and low humidity conditions.

    Management of the Stink Bugs Dolycoris baccarum (L.) and Piezodorus lituratus (F.) (Hemiptera: Pentatomidae), and Chalky Spot Damage on Red Lentil in Southeast Anatolia Region, Turkey
    (Kansas Entomological Soc, 2018) Mutlu, Cetin; Buyuk, Musa; Eren, Sedat; Karaca, Vedat; Duman, Mehmet; Bayram, Yunus
    Chalky spot damage caused by the stink bugs Dolycoris baccarum (L.) and Piezodorus lituratus (F.) (Hemiptera: Pentatomidae) is a serious problem for red lentil production in Southeast Anatolia, Turkey. This study aimed to determine spraying time against stink bugs, based on lentil developmental stages and evaluate potential agronomic methods (early vs. timely harvest and traditional harvest with sickle bar mower vs. combine harvester) to reduce chalky spot. Field trials were carried out during 2011-2012 in three provinces of Southeast Anatolia (Diyarbakir, Mardin and Sanliurfa). Chalky spot damage was initiated at the R6 stage (full seed, seed on nodes 10-13 fill the pod cavities) when the stink bug nymphs started to be observed and the plant had soft immature seeds that were more susceptible to feeding by stink bugs. In early harvested lentil fields, the percentage of chalky spot damage was 0.60 and 0.20 in Diyarbakir and Sanliurfa provinces, respectively. It was lower than that of timely harvest. On the other hand, damaged seed percentage significantly reduced by changing the harvesting from traditional to combine harvesting and damage ratio was 0.90 and 0.00 in Diyarbakir and Mardin provinces, respectively. We conclude that the management to protect lentil crops from stink bug infestations should be initiated at the R6 growth stage, and that crops should be harvested a week earlier using combine harvester to reduce stink bug density and chalky spot damage.
