An experiment was conducted to determine the effect of water stress on yield and various physiological parameters including crop water stress index for drip and furrow irrigated processing red pepper in the 2010-2011 growing seasons in the Mediterranean region of Turkey. Drip treatments consisted of full irrigation (DFI), deficit irrigation DDI-75 and DDI-50 which received 75 and 50% of DFI, respectively. D-PRD-50 and DF-PRD-50 alternative and fixed partial root drying, received 50% of DFI. Furrow treatments consisted of full irrigation (FFI), fixed alternative furrow (FAF-50) and PRD furrow (FPRD-50). FAF-50 and FPRD-50 received 50% of water applied to FFI. In FAF-50 the same furrows were irrigated while FPRD-50 was irrigated in alternate furrows. The experimental design was randomized blocks with four replications for drip and furrow treatments. Both irrigation methods and levels had a significant effect on the total yield of red pepper. Drip produced higher red pepper yields than furrow. The highest yield was obtained from the DFI treatment followed by DDI-75, DDI-50 and DF-PRD-50 treatments. Although, D-PRD-50, DF-PRD-50 and DDI-50 received the same amount of water, D-PRD-50 had a higher yield. In furrow, FFI resulted in the highest yield followed by FPRD-50 and FAF-50. The lowest water use efficiency (WUE) was obtained from the DFI while the highest WUE was found in DPRD-50 in drip system. The lowest WUE was found in FFI, and the highest WUE was in FPRD-50 treatment under furrow. The threshold crop water stress index (CWSI) was 0.26 for drip and 0.38 for furrow prior to irrigation. There was a significant relation between yield and CWSI. A high correlation was found between CWSI and leaf area index. The results revealed that DFI for the drip and FFI for the furrow were recommended. Under water scarcity conditions, DDI-75 and D-PRD-50 treatments can be recommended. © 2014 Elsevier B.V.

Plant growth-promoting rhizobacteria (PGPR) are beneficial bacteria found on plant roots that induce growth by a wide variety of mechanisms. Ten isolates of Pseudomonas and Bacillus were isolated from eggplant rhizosphere soil and evaluated for their volatile compound efficacy against mycelial growth of Fusarium oxysporum f. sp. melongenae (Fomg) and tested for their ability to colonize eggplant (Solanum melongena L.) roots in vitro. PGPR strains inhibited mycelial growth of the target pathogen and the percentage of inhibition varied from 38 % to 72 % by means of inhibitory activities. Pseudomanas aeruginosa (P07-1) and P. putida (P11-4) were determined to be successful colonizers in eggplant seedlings. Also, a pot experiment was conducted to assess the induced resistance to Fusarium wilt of eggplant by PGPR strains. Among the PGPR isolates, P. aeruginosa (P07-1), P. putida (P11-4), P. aeruginosa (85A-2), Bacillus amyloliquefaciens (76A-1) and B. cereus (B10a) significantly reduced Fusarium wilt disease incidence by up to 85 %. However, their combination was not more effective in suppressing the disease than the application of those isolates alone. The induction of peroxidase (POX, EC and polyphenol oxidase (PPO, EC enzymes was found to be significantly higher in comparison with the control group. Similarly, the proline levels in eggplants showed an increasing trend with the above isolates. However, catalase (CAT, activity was not found to significantly contribute to the induced resistance mechanism. This study revealed that the promising PGPR isolates could be potentially very useful for the biocontrol of Fomg via enhancing disease resistance in eggplant plants.

Yellow, white and blue sticky traps were tested in lemon and orange orchards for their attractiveness to thrips in Adana during 2006-2007. Traps were adjusted vertically facing to south at a height of 1.5-2.0 m of trees. Species composition and distribution of thrips in the orchards were investigated by collecting 125 flowers from different directions of the trees. Thrips damage associated with citrus crops was determined by observing 1000 fruits for scars. Blue was the most attractive to thrips in both lemon and orange orchards and can be used to estimate the population density and for properly timing control applications. Fifteen thrips species and unidentified individuals belonging to 3 genera were determined in these orchards. Frankliniella occidentalis was the most captured thrips species accounting for 82.0% of the total individuals sampled in both years. Cardinal direction of flowers did not significantly affect the numbers of thrips. Fruit damage for both years ranged between 3.8% and 9.1% depending on the citrus varieties. Lemon was attacked by thrips more than orange. © 2013 Zoological Society of Pakistan.

In this study, natural mortality factors of Citrus Leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) were investigated under field conditions. The studies were carried out in a lemon orchard in Adana, Turkey during 2007-2008. Ten trees were selected and weekly one shoot from each tree, and a total of ten shoots, were collected randomly during May-November. In the laboratory, the first 15 leaves were checked using a binocular microscope. All biological stages of the pest and the parasitoids, dead or infected individuals, and empty mines, were counted. According to the method and symptoms of predation, the mortality factors of the pest were recorded. In 2007 and 2008, large numbers of larvae were parasitized (46.25% and 48.12%, respectively). The larval parasitoid Citrostichus phyllocnistoides Narayanan (Hymenoptera: Eulophidae) was the abundant species in both years. The third instar of the host had the highest percent of parasitized individuals. In the first year, 15.33% of the pest were consumed by spiders, 10.07% by Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) and 3.14% by ants, whereas in the second year these ratios were 16.61%, 8.57% and 3.78%, respectively. Second instar larvae were the most preferred stage for predation. In 2007, in 13.66% of the mines no pests were recorded, whereas the mortality source of 5.19% of the larvae and pupae was not detected. In 2008, these ratios were 10.21% and 6.87%, respectively. It was determined that predators are as effective as the parasitoids in the biological control of the pest.

Fusarium crown and root rot (caused by Fusarium oxysporum f. sp. radicis-lycopersici, FORL) and Fusarium wilt (caused by Fusarium oxysporum f. sp. lycopersici, FOL) are the most important diseases to affect tomatoes in protected growing conditions in the eastern Mediterranean region of Turkey. These diseases cause significant yield losses in this region. Polymerase chain reaction (PCR) studies were used to characterize 87 isolates from Adana and Mersin provinces, representative of different locations. Among them, 60% and 40% of the plants were determined to have FORL and FOL, respectively. FORL and FOL race 3 are the dominant pathogens in this region. Some differences between morphological identification and molecular detection (PCR) were observed. © TÜBİTAK.

Phoenix theophrasti is the only palm species native to Turkey and it exists in small numbers in only a few locations along the Mediterranean Coast. Other Phoenix species and other palms are mainly grown in Turkey for environmental and ornamental purposes in house gardens, public gardens, parks and as street plantings. The common usage of palms in landscaping highlights their economic importance for the country, especially in coastal tourism areas. Date palms grown in Turkey produce fruits which are small in size, of low nutritional value and with little sugar content due to insufficiently warm temperatures to ripen fruit. Adult date palm trees were imported into the country, mainly from Egypt, until 2005, when imports ceased to prevent further introduction of red palm weevil, Rhynchophorus ferrugineus, which has become a serious threat to Phoenix and other palms. The other major insect problem is red palm scale insect Phoenicococcus marlatti. Measures are being taken to control these two pests. The limiting of palm imports has stimulated seed propagation of palms within Turkey.

Breeding for resistance to the cereal cyst nematodes (CCN) Heterodera filipjevi (Madzhidov,) Stelter, and H. avenae (Wollenweber) and to the root lesion nematode (RLN) Pratylenchus thornei (Sher &Allen) is presently being undertaken by breeding programs at research institutions in Turkey. This study was carried out to screen for nematode resistance in an advanced spring bread wheat breeding population, 42 lines (F9) developed at CIMMYT in Mexico, by crossing resistant parent the Middle-Eastern landrace AUS4930 7.2 and susceptible parent, the widely adapted, high yielding CIMMYT line, Pastor. The results demonstrate that 31 lines are resistant to P. thornei and 5 lines are resistant to H. filipjevi. Only 4 of these lines (2, 7, 23 and 41) are resistant to both nematodes. Lines 2, 7 and 41 also contain the known resistance gene, Cre1. Although some lines carry the Cre1 gene, they are susceptible to either both or one of these nematodes. There is no association among H. filipjevi, P. thornei and Cre1 resistance due to differences in the resistance region in the plant genome.

In this study, we aimed to determine the occurrence of Forficulidae earwigs on olive trees in the eastern Mediterrenean and southeastern Anatolia regions of Turkey. Seasonal changes in occurrence and abundance of earwigs were monitored in olive orchards in (Tarsus) Mersin and Erzin (Hatay) for two successive years. Samples were collected by using aspirator, handing, knocking and with twigs plucked from olive trees and separated in the laboratory. Six species from Forficulidae family in altogether 98 specimens were collected. Forficula aetolica Brunner, 1882 (2 specimens), F. auricularia Linnaeus, 1758 (13), F. decipiens Géné, 1832 (1), F. lurida Fischer, 1853 (41), Guanchia brignolii (Vigna Taglianti, 1974) (22), G. hincksi (Burr, 1947) (1), Guanchia sp. (14) and Forficula sp. (4) were determined in olive orchards (Oleae europae L.) in Adana, Hatay, Kahramanmaras, Mersin, Osmaniye provinces (eastern Mediterrenean region), Gaziantep and Kilis provinces (southeastern Anatolia region) of Turkey between the years 2008 and 2010. F. lurida was detected as the most abundant species. The results of this study also revelead that Forficulidae species were appeared on the trees at the middle of April and after become adults, they migrated to the soil at the end of December.
