Abstract Coptotriche spp. are known to cause damage on plants of Rosaceae and Fagaceae. Coptotriche angusticollella (Duponchel, 1843) (Lepidoptera: Tischeriidae) was recorded for the first time infesting the oil-bearing rose, Rosa damascena, at the last half of May 2017 in Isparta, Turkey. It should not be ignored that C. angusticollella can be a potential risk posed to the oil-bearing rose crop

Abstract Net blotch (NB), caused by the necrotrophic fungal pathogen Pyrenophora teres f. teres, substantially reduces barley grain yield and quality worldwide. The role of salicylic acid (SA) signaling in NB resistance has been poorly documented. In this study, SA levels as well as the expression of the SA-responsive gene PR2 were monitored in infected leaves of two barley genotypes, Banteng (resistant) and WI2291 (susceptible), at different time points of infection. SA signaling was activated in bothgenotypes 24 hours post infection (hpi) as compared with non-inoculated plants. However, with or without pathogen pretreatment, SA signifi cantly increased (P=0.001) in Banteng comparing with WI2291. RT-PCR analysis revealed that PR2 expression increases in the resistant and susceptible genotypes over the inoculation time points, with maximum expression (6.4 and 1.99-fold, respectively) observed 6 dpi. PR2 expression was paralleled by an increase in leaf SA content as shown by the test coincidence (F3, 32 = 4.74, P = 0.001). Based on barley genotype resistance levels, our data strengthen the idea that SA signaling and PR2 play a role in barley NB reduction

Summary A straightforward LC-ESI-MS/MS method was developed and validated for the detection and quantitation of the herbicide glyphosate (GLY) and its metabolite aminomethyl phosphonic acid (AMPA) in honeybees. The method was validated, fulfilling the SANTE 11945/2015 guideline criteria, demonstrating acceptable mean recoveries at LOQ and 10×LOQ varying from 75-87% for both compounds. LOQ was determined at 0.2 and 0.5 μg/g bee body weight (bw) for GLY and AMPA respectively. Analysis of 14 honeybee samples displayed only one positive sample, containing GLY marginally above LOQ and traces of AMPA.

Summary Temperature, salinity and water deficit can be major environmental constraints which reduce distribution of indigenous plants in the Mediterranean region. Laboratory experiments were carried out to assess the effect of temperature, sodium chloride (NaCl) and polyethylene glycol 6000 (PEG) on germination of Ballota hirsuta seeds. The germination responses of seeds were determined over a wide range of temperature (5 to 35°C), salinity (0 to 136 mM NaCl) and water stress (0 to −1 MPa PEG). Germination percentage was optimum at 20°C (78%), and showed a decline at lower (5°C, 25%) or higher (30°C, 18%) temperature values and total inhibition of germination at 35°C. Under salinity and water stress conditions, there was a significant deterioration in most germination parameters such as lower final germination percentage, increased mean germination times and lower germination rates.

Summary The root-knot nematode Meloidogyne incognita is a major soil parasite of lentil crops. Increasing restrictions of chemical nematicides have triggered a growing attention and interest in alternate root-knot nematode management. The present study was conducted to examine the level of resistance and/or susceptibility of five lentil cultivars (PL-456, KLS-218, Desi, DPL-62, Malika), grown in pots, against the root-knot nematode M. incognita. Root-knot nematode reproduction and host damage were assessed by recording the nematode infestation levels and reduction percentage of plant growth parameters. Nematode response and plant growth differentiated amongst the lentil cultivars. None of the cultivars was found immune or highly resistant. The cultivar Malika was found moderately resistant as it showed the lowest number of galls and egg masses/root as well as the lowest reduction of plant fresh weight (10.4%) and dry weight (6.9%). On the other hand, the cultivar Desi manifested the highest susceptibility exhibiting the highest number of galls and egg masses. There was a significantly negative correlation between the number of galls and plant growth parameters (plant fresh and dry weight and plant height).

Summary Endophytic bacteria of rice plants (Oryza sativa L.) from eight different cultivars were screened for their ability in inducing disease symptoms, plant growth promotion and antagonistic activity against Xanthomonas oryzae pv. oryzae. Out of the 63 whole isolates, five were plant pathogens. Based on phenotypic characteristics and 16S rDNA sequence analysis, these were identified as Pseudomonas oryzihabitans, P. fulva, Pantoea ananatis, Pantoea sp., Cellulomonas sp. Four out of the 63 isolates behaved as potentially good plant growth-promoting and biocontrol agents. These were identified as Bacillus sp., B. subtilis, Pseudomonas putida and Enterobacter sp. This is the first report of pathogenic and endophytic bacteria from rice grown in field conditions in North of Iran.

Summary Plants respond to stress or damage by releasing volatile compounds, primarily for defense purposes. These volatiles function as signals for different interactions of the plant with its environment. In this study, the volatile chemical profile of healthy Garcinia mangostana L. (mangosteen) leaves was compared against leaves infested with the scale insect, Aspidiotus rigidus Reyne (Hemiptera: Diaspididae) through solid phase microextraction (SPME) coupled with gas chromatography-mass spectrometry (GC-MS). Analyses revealed that leaves emit the terpene kaur-16-ene in response to A. rigidus infestation. Kaur-16-ene is a precursor of gibberellin, a plant hormone for growth and development. The results suggest that the emission of kaur-16-ene in infested G. mangostana may play a role relevant in increasing the resistance of the plant towards infestations by herbivores.
