Opuntia Cochineal Scale Pest, Dactylopius opuntiae: Current Situation, Description, Importance, and Control Methods in Countries of the Mediterranean Basin and North Africa

Systematic Review / By

The cochineal scale insect Dactylopius opuntiae (Cockerell, 1896) is one of the most significant invasive pests, causing substantial economic damage to the Cactaceae family, particularly the prickly pear genus, in various regions of the world [33]. The Cactaceae family is adapted to dry and harsh environments, characterized by high temperatures and low-fertility soils. Prickly pear …

The Role of Dialectical Materialism in Evolutionary Biology: Redefining Randomness and Environmental Influence on Mutation

Review Article / By

1.  Introduction: Randomness and the Mechanistic Model in Evolution In the neo-Darwinian framework of evolutionary biology, mutation is understood as a blind, spontaneous error in DNA replication, statistically distributed and independent of environmental needs or organismic function [1]. This perception reflects a broader mechanistic paradigm that separates the internal processes of the organism from its …

Determinations and Validations of Crop Water Requirements for Major Vegetable Crops Using CROPWAT Model at Oda Bultum District

Original Research Article / By

IntroductionThe FAO chose to help program CROPWAT 8.0 to process reference evapotranspiration (ET0), crop water requirements (CWR), water system booking, and water system water necessities (IR) utilizing precipitation, soil, yield, and environment information [13;14; 36]. Water is essential for both national growth in agricultural productivity and economic performance. However, it is transforming into increasingly scarce due to rising demand in agriculture and industry. Given that Crop …

Distribution, Abundance, and Environmental Responses of Actinobacteria in Rhizospheric and Bulk Soils of Al-Haniya, Libya

Original Research Article / By

Introduction Soil microorganisms, particularly Actinobacteria, play pivotal roles in maintaining terrestrial ecosystem functioning through organic matter decomposition, nutrient cycling, and symbiotic plant interactions [8]. Among these, the phylum Actinobacteria—notably the genus Streptomyces—has garnered global attention due to its unparalleled metabolic versatility, including the production of bioactive compounds (e.g., antibiotics, enzymes) and contributions to soil structure stabilization [18]. …

Effect of Synthetic Auxin on Water Content of Seedlings of Prosopis julifloraSwarz DC

Original Research Article / By

. Introduction The synthetic auxin 2,4-dichlorophenoxy acetic acid (2,4-D) mimics the effects of the natural auxin indole-3-acetic acid (IAA) in plants[1]. Unlike IAA quickly inactivated; 2,4-D persists for extended periods. This prolonged presence can create an imbalance in auxin levels and disrupt interactions with other hormones at the tissue level[2]. 2,4-D accumulates in chloroplasts and …
