Lumpy skin disease (LSD), a of cattle and buffaloes, has recently become widely prevalent in Egypt. The aim this study was to ascertain the potential role Rhipicephalus (Boophilus) annulatus ticks transmission disease. Samples collected from suspected lumpy virus (LSDV) infected cows that had previously been vaccinated with Romanian sheep pox (SPPV) various Egyptian governorates were obtained between May November over two consecutive years, namely 2018 2019. Ticks morphologically identified...

Abstract The objective of this work was to analyze the efficacy Cataglyphis saviginyi and Tentyrum Sp enzymatic biomarkers in evaluating environmental pollution industrial areas Borg El-Arab City, Egypt. collection C. seasonal specimens for four consecutive seasons 2020 2021, together with soil samples from site locations, conducted quantify heavy metal loadings. An analysis on lipids, proteins, carbohydrates, activities glutamic pyruvic transaminase (GPT) oxaloacetic (GOT) examined...

This investigation was aimed to evaluate water pollution with heavy metals using three biomarkers, as well the study of aquatic insects-seasons interaction.Three species insects collected from El-Mansouriya stream (Dakahlia, Egypt), during different seasons spring 2014 winter 2015.Water samples, sediments and whole body were analyzed for metal contents.As as, two enzyme Acetylcholinesterase (AChE) glutathione-S-transferase (GST) used monitor insects' response pollutants.Results showed...

The present study investigates the environmental impact of industrial activities on floral coverage within major district Borg El-Arab City, Egypt. Additionally, it aims to evaluate detoxification enzymatic activity Cataglyphis savignyi as a pollution biomarker. To achieve this objective, seasonal soil samples were collected from studied sites determine properties and heavy metal concentrations. Furthermore, specimen C. was acetylcholinesterase (AChE) glutathione-S-transferase (GST). Heavy...

Control of Culex antennatus is an important strategy for eliminating diseases transmition. Application green-synthesized silver and copper nanoparticles (AgNPs CuNPs) in mosquito' control has several advantages eco-friendly because the absence deadly chemicals their synthesis. The present study examined biological activity Rosa arabica Eucalyptus citriodora leaves aqueous extract its synthesized AgNPs CuNPs against immature stages C. antennatus, as well reproductive potential females...

The use of family variation aquatic insects in assessing freshwater quality ecosystems has only recently been applied the northern parts Africa. current study along with El Husseiny et al. (2015) and Bream (2017) can be considered first such studies Egypt. survey was conducted during period April 2015 to February 2016, permanent stream, El-Mansouriya, Dakahlia province, water health status for human this stream determined using different invertebrate biotic indices formulations (BMWP, SWRC...

Flufenoxuron caused a blockage of the production cuticle last instar nymphs since its thickness remained unchanged while that control congeners increased in as development proceeded. The formation endocuticle was prohibited, so epicuticle and exocuticle did not properly attached to epidermis. epidermis appeared with irregularly distributed cells underneath cuticle. On other hand, Lufenuron exhibited more dangerous effects. degenerated detached from which could distinguish exocuticle....

Marine gastropods are known to accumulate high metal concentrations in their tissues especially the digestive glands.In this study, accumulation of Cu, Zn, Cd, Cr and Pb gastropod Gibbula sp.(Family: Trochidae) has been assessed using Atomic absorption, spectrophotometry graphite Furnace.Animals were collected from rocky shores at Al-Hanyaa region on north-east coast Libya.Two groups animals studied; one an area adjacent a sewage outlet second was relatively clean site.Concentrations metals...

The present study evaluated the activity of ethanol 70%, acetone, chloroform and petroleum ether extracts Musa acuminata leaves against 3 rd instar larvae mosquito vector, Culex pipiens (Diptera: Culicidae) which act as a vector many diseases in Egypt.In addition, repellent tested C. adults was examined.The obtained results revealed that, all plant showed larvicidal pipiens; however, extract more effective with LC 50 571.8ppmthan chloroform, acetone ethanolic extracts, where values recorded...

Industrial pollution is one of the most dangerous that a continuous threat for humanity. Evaluation main aim current study through detection accumulated heavy metals in its surrounding habitats mainly soil and flora as well response insects towards this pollution. Therefore, seasonal collection three different insect species were performed addition to common plant; Zilla spina, at sites El-Sadat industrial city, Menofia, Egypt four successive seasons during 2016 2017. The...

Abstract Background In some localities of the Mediterranean coast and Nile land region, gall midge Schizomyia buboniae Frauenfeld, 1859 (Diptera: Cecidomyiidae) induce small barrel-shaped galls on stem Deverra tortuosa (Desf.) DC. (Family: Apiaceae). Host plants interact with several insects in a different manner. The current work studies interaction S. D. . Furthermore, present predicted distribution its host plant Egypt by using MaxEnt modeling, addition to effect elevation vegetation...

Chlorine is the most common disinfectant used in drinking water that can reacts with naturally occurring organic matter to form a number of chemical byproducts as trihalomethanes (THMs).The aims present study are investigate levels THMs Aga surface plant (ASWP) and its distribution system (DS)during period between spring 2015 winter 2016 well tanks August 2015.Drinking samples were collected from ASWP, addition to4 sites away at different distances.Other parameters temperature residual...
