Additions to the Turkish Aphid fauna (Hemiptera: Aphidoidea: Aphididae)

WOS: 000298720500021As a result of the study carried out between 2007 and 2009 in far Eastern part of the Black Sea Region of Turkey to determine aphid species on herbaceous plants, 17 species were determined as new records for Turkey aphid fauna. New recorded species are Aphis acanthoidis (Bonier 1940), Aphis brunellae Schouteden 1903, Aphis genistae Scopoli 1763, Aphis longituba Hille Ris Lambers 1966, Aphis molluginis (Bonier 1950), Aphis pseudocomosa Stroyan 1972, Aphis thomasi (Bonier 1950), Capitophorus inulae (Passerini 1860), Metopolophium tenerum Hille Ris Lambers 1947, Microlophium sibiricum (Mordvilko 1914), Sitobion miscanthi (Takahashi 1921), Uroleucon ambrosiae (Thomas 1878), Uroleucon compositae (Theobald 1915), Uroleucon kikioense (Shinji 1941), Uroleucon pulicariae (Hille Ris Lambers 1933), Uroleucon scorzonerae Danielsson 1973, Uroleucon siculum Barbagallo & Stroyan 1980. With these new records, the number of the species increased to 472 in Turkey aphid fauna.Turkish Scientific Council [TUBITAK-107T450]Authors thank to the Turkish Scientific Council (TUBITAK-107T450) for funding this project and number of aphid specialists for discussing the findings of the study during 8th Aphid Special Interest Group Meeting

Aphid (Hemiptera: Aphidoidea) species of the Urla district of İzmir region

As a result of the study organized to determine aphid fauna of the Urla district of İzmir region, 38 species were identified. Of these species, Chaitophorus saliciniger (Knowlton, 1927) and Aphis serpylli Koch, 1954 are new records for Turkey aphid fauna. With these new records, the total number of aphid species in Turkey comes up to 450. Findings of the presented study and other recent studies showed that with the detailed study Turkey aphid fauna will be substantially increased.As a result of the study organized to determine aphid fauna of the Urla district of İzmir region, 38 species were identified.

Change in cotton plant quality in response to application of anaerobically digested sewage sludge

Treated municipal sewage sludge (TSS) was applied to the cotton plant at rates of 10, 20 and 30 t/ha per year. Seed cotton yield (71.4%), lint yield (67.7%) and cottonseed yield (74.1%) were increased signifi-cantly when sludge was applied at a rate of 30 t/ha (TSS3). The effects of TSS applications on seed yield, lint yield and cottonseed yield were listed as TSS3 > TSS2 > CF > TSS1 > C according to the applications. The increasing TSS levels had a positive effect and increased the total N concentration compared to the control. The highest N value was observed in TSS3 plots, while the lowest value was recorded in control (C) plots. The highest P value was found in control (C) at 0.80% and in 10 t/ha (TSS1) at 0.80%, while the lowest value was found in the TSS2 application (0.70%). The K concentration of cottonseed increased with the increasing TSS rates, from 1.56% in control plots to 2.20% in 20 t/ha application (TSS2). Corresponding to the TSS levels, the calcium of plant tissues was determined by a range of 0.12-0.13%. The treatments of TSS and mineral fertilizer had similar effects on the Mg content of cottonseed, which was in the range of 0.38-0.43%. Na content in plant tissue increased with increasing dose of sludge application compared to control soils. Increasing doses of TSS had no significant effect on the concentrations of iron (Fe), copper (Cu), zinc (Zn), manganese (Mn) and boron (B) in cottonseed. The order of the elements with respect to their amounts in cottonseed was as follows: Fe > Zn > Na > B > Mn > Cu. The concentrations of non-essential elements (Ni, Cd, Cr, Pb, Hg and As) in cottonseed were below the permissible limits. (c) 2021 The Authors.
