First Records of Armoured Scale Insects (Hemiptera: Coccoidea: Diaspididae) From the Oil-Rose, Rosa Damascena, in Turkey
(2009) Demirözer, O.; Kaydan, M.B.; Karaca, I.; Ben-Dov, Y.
The olive Parlatoria scale, Parlatoria oleae (Colvée) and the apple oyster-shell scale Lepidosaphes ulmi (L.) (Hemiptera: Coccoidea: Diaspididae) are recorded for the first time infesting the oil-rose, Rosa damascena, at Isparta, Turkey. These armoured scale insects are considered as potential pests to the cultivation of the oil-rose. © Benaki Phytopathological Institute.
The Life Table of Cryptolaemus Montrouzieri Mulsant (Coleoptera: Coccinellidae) After Different Storage Periods
(WFL Publisher Ltd., 2006) Özgökçe, M.S.; Atlihan, R.; Karaca, I.
The life table of Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) was calculated on Planococcus citri (Risso) (Homoptera: Coccidae) under laboratory conditions at 25±1°C and 45±5% relative humidity after different storage periods at 15°C of cooling. Experiments consisted of 5 groups including a control and design experiments that were run for 5, 10, 15 and 20 days, respectively. The following predictive parameters were obtained for the control and design experiments: intrinsic rate of increase rm = 0.098, 0.092, 0.074, 0.058 and 0.045; net reproductive rate R0 = 340.703, 276.629, 149.930, 119.321 and 65.928; mean generation time T0 = 59.350, 60.851, 67.726, 83.189 and 94.173, respectively. Doubling time DT = 7.2, 7.9, 9.3, 12.1 and 15.3, and finite rate of increment λ = 1.101, 1.092, 1.074, 1.059 and 1.046, were calculated as well. The reproductive value (Vx) for each group was plotted.
Maternal Age Effects on Fecundity and Survival of Aphis Fabae Scopoli (Hemiptera: Aphididae) on Bean
(Entomological Society of Turkey, 2015) Yüztaş, G.; Karaca, I.; Özgökçe, M.S.
In this study, the effects of maternal age on development, fecundity, longevity, generation time, preoviposition, oviposition and postoviposition times and survival rate of bean aphid, Aphis fabae Scopoli (Hemiptera: Aphididae) were investigated. At the experiments, four different populations generated by 1, 6, 11, and 16 days old mother were used. For each experiment group, 45 replicates were used and bean leaves were used as host plant for aphid population. Experiments were carrried out at 27±1° C, 60±5% r.h. and 16:8 L:D photoperiod in a climate chamber. Data obtained for each populations were evaluated according to the age-dependent life tables. Calculation of life table parameters were made by using Euler-Lotka equation. Values obtained for intrinsic rate of increase (rm), net reproductive rates (Ro), mean generation time (To), gross reproductive rate (GRR) and finite rate of increase (λ) were 0.369, 0.389, 0.349 and 0.149 females/female/day; 16.466, 14.535, 7.802 and 2.233 females/female, 7.599, 6.873, 5.893 and 5.388 days, 37.611, 28.126, 20.265 and 16.000 females/female, 1.446, 1.476, 1.417 and 1.161 females/days respectively for Aphis fabae populations formed by 1, 6, 11 and 16 days old mothers. Preoviposition period values for all experiment groups were zero. Values obtained for adult life times, oviposition period, postoviposition period and generation time were 6.4, 6.8, 2.6 and 0.4 days,6.2, 8.3, 2.4 and 0.4 days, 0.2, 0.2, 0.1 and 0 days, 7.0, 7.2, 5.9 and 4.8 days respectively,for the aphidpopulations generated by 1, 6, 11 and 16 days aged mothers. Best fit curves were obtained by using Weibull distribution for age dependent survivals (lx) of each populations, and their parameters were calculated. According to parameters calculated in Weibull distribution, it was found that 1. and 2. age group populations were suitable to Holling's type 1 life curve and 3. and 4. age group populations were suitable to type 3 life curve. © 2015, Entomological Society of Turkey.

Zooplankton Composition of Van Lake Coastline in Turkey
(Academic Journals, 2010) Yildiz, S.; Özgökçe, M.S.; Özgökçe, F.; Karaca, I.; Polat, E.
This study was completed with periodical surveys in coastal band of Van Lake between May and September in 2005 to 2006 period. It was carried out on a total of 20 sites selected as sampling points and having three distinct characteristics. During the study, a total of 20 species (14 belonged to genus of Rotifera, 4 to Copepoda and 2 Branchiopoda) were found at the Van Lake coastal zone. Genera Notholca squamula, Keratella quadrata, Colurella colurus, Lecane ohiensis, Lecane grandis and Lecane lamellata have been detected for the first time at the Van Lake coastal zone. © 2010 Academic Journals.
