Effect of Temperature on the Biology of Aphis punicae (Passerini) (Homoptera: Aphididae) on Pomegranate

Abstract The effect of temperature on development time, reproductive capacity, and rate of survival for Aphis punicae was studied at five different (constant) temperatures (17.5, 20, 22.5, 25, and 27.5°C). The development period for immature instar stages ranged from 11.72 d at 17.5°C to 4.30 d at 27.5°C. The lowest developmental threshold was 11.8°C, and the thermal constant (K) was 66.4 DD. The percentage survivorship of immature stages varied from 72.0 to 90.0% over a temperature range of 17.5–27.5°C. The average longevity of adult females was 16.50, 17.17, 18.16, 12.04, and 8.91 d at temperatures of 17.5, 20, 22.5, 25, and 27.5°C, respectively. The average number of offspring produced by a single female was 14.65, 22.68, 31.34, 21.31, and 11.27 at temperatures of 17.5, 20, 22.5, 25, and 27.5°C, respectively. The greatest rm (0.3292) was observed at 25°C. The optimal temperature for A. punicae growth, development, and reproduction was 22.5–25°C.

Effects of Different Cucurbit Species and Temperature on Selected Life History Traits of the 'B' Biotype of Bemisia tabaci

The development time and survival rate were determined at three constant temperatures for the ‘B’ biotype ofBemisia tabaci on cucumber (Beit Alpha F1), cantaloupe (Anzer F1), squash (Sakız F1), and watermelon (Galactica F1). The development time for immature stages at 20, 25 and 30±1°C was, respectively, 33.5, 19.3 and 16.8 days on cucumber; 36.5, 20.8 and 19.60 days on cantaloupe; 37.2, 20.1 and 19.8 days on squash; and 38.9, 23.8 and 21.9 days on watermelon. At 20, 25 and 30°C, the respective percentage survival of immature instars was 73.2, 83.2 and 72.9% on cucumber; 72.9, 84.9 and 75.6% on cantaloupe; 52.1, 76.1 and 57.5% on squash; and 37.6, 64.8 and 40.1% on watermelon.

Akdeniz Bölgesi’nden toplanan Bemisia tabaci (Gennadius) (Hemiptera:Aleyrodidae) popülasyonlarının biyotiplerinin belirlenmesi

Bu calisma, Akdeniz Bolgesi tarimsal alanlarinda ki yaygin Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) biyotipini belirlemek amaciyla yurutulmustur. Bu amacla Akdeniz Bolgesi’nde Antalya, Adana, Mersin ve Hatay illerinden 2009-2012’de farkli ilcelerdeki uretim alanlardan beyazsinek ornekleri toplanmistir. SCAR-PCR metodu kullanilarak B ve Q biyotip olan bireyler belirlenmistir. Toplanan 27 populasyonun ikisi Q biyotipi, 25’i B biyotipi olarak saptanmistir. Akdeniz Bolgesi’nde bulunan bu iki biyotipin kismen de olsa farkli habitatlari tercih ettikleri kanaatine varilmis olup, ozellikle B biyotipinin sebze alanlarinda yogunlastigi, Q biyotipin ise iki yillik bitkilerde agirlikli olarak bulundugu sonucuna varilmistir.

Faunistic studies on Aleyrodidae species of Bartın and Kastamonu provinces

The aim of this study was to determine Aleyrodidae fauna in Bartin and Kastamonu provinces. In total six whiteflies species were recorded in this study, three of them namely Aleutrachelus rhamnicola (Priesner & Hosny), Siphoninus immaculatus (Heeger) ve Trialeurodes abutiloneus (Haldeman) were new records for the Turkish fauna. Information about their identification, host plants, and distribution in Turkey and in the world were presented as detailed.

New record of invasive aphid: Myzocallis walshii (Monell), 1879 (Hemiptera: Aphidoidea) in Turkey

This study was conducted to determine aphid species on ornamental plants in Adana region of Turkey. Surveys were conducted weakly in spring and early summer in 2012 and two aphid species, Myzocallis walshii (Monell), 1879 (Hemiptera: Aphidoidea) and Myzocallis castanicola Baker, 1917 (Hemiptera: Aphidoidea) were found on oak trees (Quercus ilex L.) (Fagaceae). M. walshii is first time recorded for Turkish aphid fauna in this study.
