In Algeria it causes a lot of damage. This species is known for its large chromatic and geographical polymorphism. To better understand the biology of this insect, we studied the quality and quantity of its diet. It is performed according to the conventional method of faecal analysis and complemented by quantification of ingested plants by using the method called “windows”. This method allows the identification with certainty of the quantity of plants ingested by the Orthoptera. It is based on calculation of the recovery rate of the plants, preparation of reference epidermis and analysis of feces. An index of palatability for each species is calculated from leaf surfaces ingested by each individual. It indicated that the trophic spectrum is very large and concluded that this insect is polyphagous with graminivorous trend. In fact, the most consumed vegetable species, any confused parameter, is <em>C. vesicaria</em>. Ii is followed respectively by <em>V. myuros, P. serraria and C. dactylon</em>. On the other hand, we noticed that the palatability index is not conforming to the recovery rate of the plants in the field and the most ingested plants are not necessarily the most appetizing.</p> Rouibah Moad Nawouel Ferkhi Djamila Labiod ##submission.copyrightStatement## 2018-02-13 2018-02-13 6 1 45 56 Combination of nitric Oxide and thiamin regulates oxidative defense machinery and key physiological parameters in salt-stressed plants of two maize cultivars differing in salinity tolerance <p>A glasshouse experiment was conducted to appraise&nbsp; the influence of combined nitric oxide (NO) and thiamin (TA) on oxidative defense system and some key physiological attributes in two maize cultivars (DK 5783 and Apex 836) stressed with 0 (control) or 100 mM NaCl.&nbsp; Of six NO and TA levels used in the initial germination experiment, 2 levels of combined NO and TA (3 +100 or 6+ 125 mg l<sup>-1</sup> respectively) were chosen for subsequent studies as seed soaking or as a spray to seedlings. Salinity resulted in rising leaf free proline content and osmolality, but in a decrease in plant dry biomass and maximum fluorescence yield (<em>F</em><sub>v</sub><em>/F</em><sub>m</sub>) in cultivars. Both modes of applied NO and TA were found to be effective in alleviating the adverse effects of NaCl on shoot growth. Salt stress resulted in enhancing leaf Na<sup>+</sup>, but reducing leaf K<sup>+ </sup>and Ca<sup>2+ </sup>in plants. Both modes of application of NO and TA resulted in increased Ca<sup>2+</sup> and K<sup>+</sup> contents, but decreased those of&nbsp; Na<sup>+</sup> in salt stressed maize plants. Salt stress caused the enhanced accumulation of hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) and malondialdehyde (MDA).&nbsp; Salinity promoted the activities of catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) in maize. The growth improvement in maize plants due to exogenously-applied&nbsp; NO and TA in combination&nbsp; was found to be due to decreased leaf Na<sup>+</sup>, H<sub>2</sub>O<sub>2 </sub>and MDA levels, and altered&nbsp; activities of SOD, CAT, and POD as well as improved maximum fluorescence yield under saline stress.</p> Cengiz Kaya Muhammad Ashraf Osman Sonmez ##submission.copyrightStatement## 2018-02-02 2018-02-02 6 1 34 44 Seasonal incidence of Aphis craccivora Koch on Vigna mungo and Vigna radiata with its predator Cheilomenes sexmaculata (Fabricius) (Coleoptera: Coccinellidae) <p>The knowledge of interaction of prey and predator in relation to host plants in particular season is very necessary for pest management. The seasonal study of <em>Aphis craccivora </em>Koch (Hemiptera: Aphididae) and its predator <em>Cheilomenes sexmaculata</em> (Fabricius) (Coleoptera: Coccinellidae) were carried out in two seasons on two most common pulses (<em>Vigna mungo</em> and <em>Vigna radiata</em>) under agroclimatic condition. The appearance and population buildup of <em>A. craccivora</em> and <em>C. sexmaculata</em> were observed host plants, temperature and humidity dependent. During both the years, one standard peak of infestation of <em>A. craccivora</em> was observed on <em>V. radiata. </em>However, one standard peak was observed on <em>V. mungo</em> only in the first year. The activity of aphids was recorded from October to January (4 months) on <em>V. radiata </em>and<em> V. mungo.</em> Generally, the first association of <em>C. sexmaculata</em> was observed after 6<sup>th</sup>&nbsp; weeks (16.9 ºC, 51% RH) on <em>V. radiata </em>and no association was recorded on <em>V. mungo </em>in first year but in the next year the first association was recorded after 8 weeks (16.9 ºC, 80%RH) on <em>V. mungo </em>&nbsp;from the date of appearance of aphid in the field. Aphids and predators interaction are greatly influenced by environmental conditions, such as temperature, relative humidity, rainfall, wind and sunshine hours. Thus, the seasonal study of aphids and their predator plays important role for effective management of pest and conservation of natural enemies.</p> Dr Rakhshan Equbal Ahmad Sanjeev Kumar ##submission.copyrightStatement## 2018-02-01 2018-02-01 6 1 26 33 An In Vitro Endosperm Culture of Anthurium <p><em>A new route of in vitro endosperm culture of Anthurium andreanum Linden ex André aiming to regenerate triploid plants was successfully established. Regenerative callus up to 100% with + callus score was determined on Vacin and Went (VW) medium fortified by 0.75 mg/l thidiazuron (TDZ) and 0.15 mg/l benzylaminopurine (BAP) after periodical subcultures on half-strength Murashige and Skoog (MS) medium supplemented with 0.12 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D), 0.75 mg/l TDZ and 0.5 mg/l BAP. High regeneration of shoots was proved in New Winarto Teixeira da Silva (NWT) medium supplemented with 0.25 mg/l 2,4-D, 1.5 mg/l TDZ, 0.75 mg/l BAP and 0.02 mg/l α-naphthalene acetic acid (NAA) and increased gradually from 3.6 - 13.5 shoots per callus subcultured after periodical subcultures. The shoots were easily rooted on&nbsp; NWT medium containing 0.06 mg/l 2,4-D, 0.37 mg/l TDZ, 0.5 mg/l BAP and transferred ex vitro in a mixture of burned-rice husk, raw rice husk and organic manure (2:2:1, v/v/v) with acclimatization process described in the previous research resulting in 48-74% of plantlet survivability. The acclimatized-plants derived from the in vitro endosperm culture of the anthurium successfully produced 5-12.5% or 2-4 triploid plants out of 22-37 survival plantlets. The research results can be applied and improved for producing triploid plants on different anthuriums.</em></p> Budi Winarto Rudy Soehendi Harwanto - ##submission.copyrightStatement## 2018-01-17 2018-01-17 6 1 13 25 Rice Fields Chemical and Physical Properties and the Implications on Breeding Strategies <p>Soil related constraints are major limiting factors in crop production in the Sahel. &nbsp;The objective of this study was to assess the properties of farmer’s fields soil and irrigation water in Niger and the implications in rice improvement. Composite soil samples were collected from irrigated and non-irrigated fields. Sample of irrigation water was also collected. Physical and chemical analyses were performed in the laboratory. The results showed that most of rice fields were clayey and the non irrigated ones were mostly sandy. The soils were acidic and saline, the electrical conductivity ranged from 2.2 to 16.5 decisiemens per meter. The T-test showed that total dissolved salt, sodium adsorption ratio, cation exchange capacity, and organic matter percentage were significantly higher in irrigated fields than non-irrigated fields. The irrigated soils pH varied from 3.2 to 6.8, the electrical conductivity was greater than 4, and the sodium adsorption ratio was below 13 while the exchangeable sodium percentage was below 15. The irrigation water samples varied in term of ion content from site to site. The total sodium quantity estimated to be deposited varied from 87 kg/ha/year to 218 kg/ha/year. Rice fields’ soils are saline and are getting worsened by irrigation water that contains salt. Therefore, the development of rice varieties that could withstand osmotic and ionic salt stress is necessary for sustainable production in the Sahel ecozone.</p> Souleymane Oumarou Eric Nartey Batieno Teyioué Benoit Joseph Baboucarr Manneh Kwadwo Ofori Eric Danquah ##submission.copyrightStatement## 2018-01-16 2018-01-16 6 1 01 12
