The reproductive biology of&nbsp;<em>Arius latiscutatus </em>Günther, 1864 and&nbsp;<em>A. gigas </em>Boulenger, 1911 was studied through monthly sampling, from January to December 2016.</p> <p><strong>Methodology:</strong> Fish were caught using gill nets in several sampling sites. Five gonadal stages were described, based on macroscopic observation of gonad form, size, weight, color and oocyte diameter.</p> <p><strong>Results: </strong>The population was dominated by males (61%) in <em>A. latiscutatus</em> and females (53%) in A. gigas, showing a sex-ratio of 1:1.54 (Chi-square, <em>P </em>&lt; 0.05) and 1:0.88 (<em>P </em>&gt; 0.05), respectively. The length-weight relationship was a positive allometry for <em>A. latiscutatus and A. gigas</em>, and males (35.37 and 35.47 cm, respectively) reached first maturity earlier than females (39.7 and 40.8 cm, respectively). Changes in the gonadosomatic index (GSI) and in stages of gonadal development showed that&nbsp;<em>A. latiscutatus&nbsp;</em>spawned between April and October, while&nbsp;<em>A. gigas&nbsp;</em>spawned in May to November. The peak of condition factor was observed in June (0.68±0.05) and July (0.55±0.04) in females of <em>A. latiscutatus</em> and <em>A. gigas</em>, respectively.</p> <p><strong>Conclusion: </strong>Both species, having only one annual breeding season, <em>A. latiscutatus</em> spawns earlier than <em>A. gigas</em>. Coastal fisheries should be restricted in cold season to preserve the ability of broodstock renewal for these species.</p> Pierre Koivogui Yao Aristide Konan Bakari Coulibaly Essetchi Paul Kouamelan Tidiani Koné ##submission.copyrightStatement## 2020-08-05 2020-08-05 1 13 10.9734/arrb/2020/v35i830254 About the Influences of Some Major Biotic Drivers on the Population Dynamics in Host-parasite Systems: Interpretative Lessons from an Extended Nicholson-Bailey Model <p>Population dynamics within host-parasite systems in insects is governed by a series of factors, both endogenous and exogenous. Among them, five factors may be considered as major drivers: the respective inherent rates of increase of the host and of the parasite, the level of resource available to the host, the respective immigration rates of the host and of the parasite. While only the first two (the inherent rates of increase of host and parasite) are considered in the original Nicholson and Bailey model, an extended version of the model includes also the other three parameters, thus providing a broader (although still schematic) approach to the host-parasite population dynamics. A brief analysis of the respective influences of each of these five driving parameters on the main features of host-parasite dynamics is derived accordingly, based upon this extended model. Finally, specific attention is paid to the major concerns due to the cyclic outbreaks of both the host and the parasite, regarding in particular the amplitude, the periodicity and the conditions of onset of the cyclicity. Both the practical aspects of the cyclic regime and its possible adaptative significance are discussed. As a whole, this approach aims to provide some general clues for the interpretation of various features of the host-parasite dynamics, as reported from field observations.</p> Jean Béguinot ##submission.copyrightStatement## 2020-08-05 2020-08-05 14 32 10.9734/arrb/2020/v35i830256 Agronomic Behavior of Six Saladette Tomato Hybrids Grown under Shade Mesh <p><strong>Aims: </strong>The objective was to evaluate six indeterminate saladette tomato hybrids in Southeast, Coahuila, Mexico.

The polymerase chain reaction (PCR) is central in the molecular studies and provides ways for diagnostic advancement in the areas. However, the requirement for thermal cycler in a dedicated facility for amplification of target genes in the PCR technique has been a bottleneck to many researchers. The limitations associated with PCR include cost implication, strict expertise necessity and relatively higher turn-around time. The emergence of loop-mediated isothermal amplification (LAMP) in the last two decades assists in bridging the undesirable gaps. This review aims to highlight the natural advantages of the LAMP technique over the existing conventional PCR and other isothermal molecular techniques. Available published articles on LAMP techniques reviewed, listed many outstanding advances of the method in comparison to traditional PCR technique. The mentioned advantages include simplicity, affordability, naked-eye result detection and many more. That made LAMP becomes a rapidly accepted method in the field of molecular diagnosis. Other essential features of LAMP in comparison with other emerging nucleic acid amplification techniques were adequately explained and presented in tabular form for research and quick reference purposes. Though LAMP has some few limitations, its advantages outweigh its flaws by filling the gap in the field of molecular biology diagnostics.</p> Yahaya Hassan Leslie Thian Lung Than ##submission.copyrightStatement## 2020-08-08 2020-08-08 33 44 10.9734/arrb/2020/v35i830257 Host Preference, Mode of Damage and Succession of Major Insect Pests of Brinjal <p>Brinjal is one of the most popular solanaceous vegetables worldwide because of its nutritive and nutraceutical values. In recent decades, brinjal cultivation has been experiencing increased biotic and abiotic stresses due to the climate changes, which had affected the cultivation practices, growers’ profit and consumers’ choice to a larger extent. Amongst different insect pests, brinjal shoot and fruit borer (BSFB) is the major one causing significant reduction in economic yield followed by epilachna beetle, aphid, jassid and whitefly. On the other hand, proper knowledge on nature of damage, host preference, and seasonal abundance of insect pests is a pre-requisite for development and deployment of an appropriate, effective and timely management strategy against the pests.&nbsp; A pool of literatures on host preferences, damage pattern and succession of major insect pests of brinjal has been reviewed and presented in this paper.</p> Saifullah Omar Nasif Shafiquzzaman Siddiquee ##submission.copyrightStatement## 2020-08-13 2020-08-13 68 78 10.9734/arrb/2020/v35i830261
