Characterization of Pseudomonas syringae PV. syringae from diseased stone fruits in Kyrgyzstan and testing of biological agents against pathogen

Tinatin DOOLOTKELDİEVA | Saykal BOBUŞOVA

The plant diseases caused by the Pseudomonas syringae сomplex bacteria are economically important and occur worldwide on various plants, and it is as a pathogen that has not been the object of studies and little is known about its epidemiology in Kyrgyzstan. The conventional phenotypic (LOPAT, API tests) and PCR-assisted isolation were used for the identificationof Pseudomonas syringae pv. syringaе isolates from the affected organs of local stone fruits, such as peach (Prunus persica), cherry (Prunus subgen), apricot (Prunus armeniaca), and plum (Prunus salicina) samples taken from the Chy, Is ...Более

Genetic Relationships and Population Structure of Central Asian Apple Species collected from Different Parts of Kyrgyzstan

Abdıkerim ABDULLAYEV

Apple is among the most widely grown fruit species worldwide. It is included in the genus Malus and there are several species of apple. Although a consensus is not available about the origin of domesticated apples, it is widely accepted that Malus sieversii, known as Central Asia wild apple, was the primary progenitor of apples. Central Asia is a quite significant origin center of apple and harbors different species and a great diversity. In this study, genetic relations among 79 apple materials belonging to 4 different species (M. domestica, M. sieversii, M. kirghisorum and M. niedzwetzkyana) ...Более

Characterization and pathogenicity of Rhizoctonia isolates collected from Brassica oleracea var. acephala in Ordu, Turkey

İsmail ERPER

A total of 30 Rhizoctonia isolates were collected from plants with Rhizoctonia-like symptoms in kale growing areas in Ordu province during the 2014-2015 growing seasons. All the isolates were identified using nuclear staining tecnique and the nucleotide sequence analysis of the nuclear rDNA internal transcribed spacer (ITS)1-5.8S-ITS2 region. The most prevalent anastomosis group (AG) was AG 2-1 (36.67?f isolates), followed by AG-A (30? AG 4 HG-I (10? AG 5 (6.67? AG-Fb (6.67? AG-E (6.67?and AG-K (3.33? Cultural characteristics showed that randomly selected RsCB-13 (AG 2-1), RsCB-20 (AG 4 HG-I), ...Более

Efficacy of the entomopathogenic fungi; Beauveria bassiana and Metarhizium anisopliae against the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae)

İsmail ERPER

The efficacy of the two entomopathogenic fungi, Metarhizium anisopliae (TR 106) and Beauveria bassiana (TR 217), was tested against the adults of the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae) in laboratory. Two concentrations of conidial suspensions (1 x 10(6) and 1 x 10(8) conidia/ml) of M. anisopliae and B. bassiana isolates were directly applied on four pairs of adult beetles in Petri dishes (2 ml/dish) and then incubated at two different climatic regimes; 22 +/- 1 degrees C and 26 +/- 1 degrees C with 70 +/- 5% RH, 16:8 h light-to-dark. Lethal time v ...Более

MOLECULAR IDENTIFICATION OF COTTON WHITEFLY BEMISIA TABACI GENN. (HEMIPTERA: ALEYRODIDAE) POPULATIONS OF TURKEY BASED ON MITOCHONDRIAL CYTOCHROME OXIDASE SUBUNIT I

Hüseyin GÖÇMEN

The cotton whitefly (Bemisia tabaci Genn.) is a major pest of cultivated plants in tropical and subtropical regions. In this study, the genetic diversity between populations and various biotypes of B. tabaci collected from Hatay, Adana, Icel, Antalya, Mugla, Aydin and Denizli provinces of Turkey were investigated using mitochondrial cytochrome oxidase subunit 1 (mtCOI) sequences. Thirty-two nucleotide variations were found in a 617 bp mtCOI sequence of the among the populations studied. Phylogenetic analysis divided the B. tabaci populations of Turkey into two groups clustering around the main ...Более

The utility ofTrichodermaspp. isolates to control ofXylosandrus germanusBlandford (Coleoptera: Curculionidae: Scolytinae)

İsmail ERPER

The invasive ambrosia beetle,Xylosandrus germanusBlandford (Coleoptera: Curculionidae: Scolytinae), is a serious pest of hazelnut in Turkey, which is the biggest hazelnut producer in the world. In this study, the utility of four isolates representing differentTrichodermaspecies (T. harzianum,T. hamatum,T. asperellum, andT. atroviride) was evaluated on survival, gallery behavior and brood production ofX. germanusby effecting the symbiotic fungal development at laboratory conditions. Hazelnut branches were exposed to fungal suspensions (1 x 10(6)and 1 x 10(8)conidia mL(-1)doses) for about 30 s. ...Более
