Interactions between lady beetles and the European fire ant (Myrmica rubra L.) tending potato aphids [Macrosiphum euphorbiae (Thomas)] were compared in the laboratory. Lady beetle species native to North America (Coccinella trifasciata perplexa Mulsant, Coleomegilla maculata lengi Timberlake, Hippodamia convergens Guérin-Méneville) and non-native species of Palearctic origin [Coccinella septemp...

In late summer, heteroecious aphids, such as the potato aphid, Macrosiphum euphorbiae, move from their secondary summer host plants to primary host plants, where the sexual oviparae mate and lay diapausing eggs. We tested the hypothesis that volatiles of the primary host, Rosa rugosa, would attract the gynoparae, the parthenogenetic alate morph that produce oviparae, as well as the alate males ...

Çalışma, 2010-2011 yılları arasında Kahramanmaraş il merkezi (Dulkadiroğlu, Onikişubat), Göksun, Türkoğlu ve Pazarcık ilçelerinde zeytin, elma fıstık bahçelerinde bulunan Coccoidea üst familyasına (Hemiptera: Sternorryncha) ait türlerin saptanması için yürütülmüştür. Survey çalışmalarında, 3 familyadan 12 tür tespit edilmiştir. Bu türler; Aulacaspis rosae (Bouché), Filippia follicularis (Targio...

Resistance responses in the leaves of eight rose genotypes, Knock Out (highly resistant), Arka Nishkant (moderately R. multiflora susceptible), Swadesh IIHRR 13-4 (susceptible), Parimala indica (susceptible) and 4-15-12 exhibiting varied levels resistance against black spot were investigated post artificial inoculation with pathogen, Diplocarpon rosae. There was consistent increase activities d...
