Influence of Some Insecticides on The Incidence of Common Lepidopterous Insect- Pests in Cotton Field

Abstract

The journal of Toxicology and pest control is one of the series issued twice by the Egyptian Academic Journal of Biological Sciences, and is devoted to publication of original papers related to the interaction between insects and their environment. The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net Provided for non-commercial research and education use.Not for reproduction, distribution or commercial use. ABSTRACT Article History

Toxicological and Histological Evaluation of Insecticides and Essential oils in Nano emulsion and formulated Form against Spodoptera littoralis

“…The Egyptian cotton leafworm Spodoptera littoralis (Lepidoptera: Noctüidae) is one of the most destructive pests to about 112 host plants from different families. Infestation often leads to significant crop losses and reduced marketability (Ismail et al 2020). The most effective control of S. littoralis has been achieved by using chemical pesticides.…”

Enhancing the Toxicity of Cypermethrin and Spinosad against Spodoptera littoralis (Lepidoptera: Noctuidae) by Inhibition of Detoxification Enzymes

“…It feeds on the leaves of several old- and new-world plant species throughout the year [ 2 ]. The overuse of synthetic pesticides against S. littoralis has resulted in increasing synthetic insecticide resistance, which has become a crucial issue for successful pest management [ 3 , 4 , 5 , 6 ]. Moreover, several environmental and health problems and harmful effects on natural enemies were observed [ 7 , 8 ].…”

“…Furthermore, the inhibition of enzymes could be the result of the synergists of the essential oils when mixed with CYP to control S. littoralis [ 1 ]. Thus, one of the fundamental processes for reducing insect resistance to insecticides is the inhibition of detoxification enzymes [ 3 ].…”

Toxicity and Biochemical Effect of Certain Insecticides against Spodoptera littoralis (Boisd.)

“…This will give the chance to replace the failed controlling agents by the effective alternatives. Moreover, the establishment of baseline susceptibility and the mechanism of resistance are necessary for effective resistance management strategies (Ismail et al, 2020). The current trend in insect pests' controls is search for development of new control agents having novel biochemical targets to solve pest resistance problems ( (Silva et al, 2016;Sridhar et al, 2016 andIsmail, 2020).…”
