Field Evaluation of Date Palm Dust Mite, Oligonychus afrasiaticus (McGregor) Control on Date Palm Trees in New Valley Governorate of Egypt

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.

Toxin-Pathogen Synergy Reshaping Detoxification and Antioxidant Defense Mechanism of Oligonychus afrasiaticus (McGregor)

“…Such damages imparted significant reduction in fruit quality and quantity and making dates unfit for human consumption. Management of O. afrasiaticus infestations mainly relied on the frequent application of wide range of synthetic acaricides [ 7 , 13 , 14 , 15 , 16 ]. However, indiscriminate application of synthetic acaricides resulted undesirable scenarios due to residual toxicity, poor selectivity, environmental pollution, bioaccumulation, and low efficacy [ 13 , 17 ].…”

Some Physiological Observations on Date Palm Fruits during its infestation by the date palm dust mite, Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae)

“…The production of date in the Arabian Peninsula and the Middle East has increased and expected to increase more (Chao and Krueger 2007). The date palm fruits are of high energy fruit with numerous medical, social, food, and industrial values (El-Halawany et al, 2017). About 55 cultivars of date palm fruits are commercially produced in Egypt ` (Bekheet and El-Sharabasy, 2015).…”

“…The phytophagous harmful mites belong to genus Oligonychus(Acari: Tetranychidae) especially, the old world date mite, O. afrasiaticus (McGregor) are known to occur in most date palm growing areas in the world (Basshaih 1999, Ben Chaaban et al (2017), El-Halawany et al (2001, Elwan, 2000, Talhouk (1991.The distribution variance of this pest seems to be a phenomenon occurring everywhere independent of climatically or geographical zones and often related to changes in the chemical composition of dates (Ben Chaaban and Chermiti, 2009). These mites can cause very serious damage to fruits (size, weight, sugars, moisture contents, and acid activity) (El-Halawany et al, 2017). In the USA, there is direct damage caused by the mite O. pratensis Banks on immature green date fruit (making a hole in cells and sucking the juice from the surface of the fruit).…”

Toxicity of some Acaricides Against Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae) under Laboratory Conditions in The New Valley, Egypt

“…These species are distributed among eight insect orders and 30 families, besides a single order of mites pertaining to nine families. The O. afrasiaticus is a serious pest of date palms (El-halawany et al, 2017;Ben Chaaban and Chermiti, 2009;Blumberg, 2008. The mites suck the fruit sap through the skin, covering bunches with dense webbing that hinders photosynthesis. Heavy infestations can lead to partial or total yield loss.…”
