Toxicity of certain plant oils on pupil stage of the peach fruit fly, B. zonata (sunders) (tephritidae: diptera)

Abstract

The Peach fruit fly, Bactrocera zonata (sunders) is known as the most serious fruit insect pest, this work carried out to test the toxicity of ten essential oils against one day old pupa of this pest by using 4 concentrations for each oil. Results revealed that eucalyptus oils was the most toxicity oil against B. zonata pupa with low LC 50 value of 38.88ml/L followed by Basil oils followed by Onion, peppermint, ginger, garlic, water crass, clove, castor and

Insecticidal potential of some plant extracts in nano and normal form on immatures stages of red palm weevil Rhynchophorus ferrugineus

“…The results indicated that there were significant differences among the used treatments and concentrations. These findings are in agreement with previous studies where castor have been proved to have insecticidal activities against, peach fruit flies (Ali, 2018), RPW, (Ali et al, 2019) Maconellicoccus hirsutus (Holtz et al, 2019), The toxic activity of castor is probably due to the presence of its major active components such as :the alkaloid ricinine, Nmethyl ricinine and the ricin protein, which are toxic substances in the leaves. (Worbs et al, 2011;Fallström, 2014;Polito et al, 2019), these active components cause reduction in all types of hemocytes and plasmocytes, it decreased carbohydrate content, (Ali and Ibrahim, 2018).…”

“…Eucalyptus had an insecticidal against activity against wide range of insect pests, peach fruit fly (Ali, 2018), Tribolium castaneum (Herbst) (Ahmad et al, 2019) and RPW (Ali et al). The botanical activity of eucalyptus oils return to its major contents like 1,8-cineole, limonene, linalool, a-pinene, and a-terpineol, (Batish et al, 2008;Noumi et al, 2011), 1,8-Cineole, leading to damaged structural stability of the cell, leading successively to increased permeability (Verma et al, 2017).…”

Efficacy of some promising plant essential oils to control the red palm weevil Rhynchophorus ferrugineus olivier (coleoptera: curculionidae) under laboratory conditions

“…similarly, Kim, Soon-Il, Lee, Dae-Weon (2014) reported that basil oil, orange oil, and their components could be potential candidates as new fumigants for the control of S. zeamais and T. castaneum adult. While, findings of Ali (2018) showed that castor oils have active toxicity against pupa of thae peach fruit flies.…”

“…Terpinen-4-ol; 1,8-cineol; verbenone and camphorin Eucalyptus oil were active against A. obtectus adults (Tholl, 2006), insecticidal, and antifeedant against biting insects, (Singh, Kohli, & Kaur,2008;Bakkali, Averbeck, Averbeck, & Idaomar, 2008). also has high insecticidal activity against the pupa of the peach fruit flies (Ali, 2018). Saad, M., (2017) results revealed that essential oils (S. aromaticum) have the highest oviposition deterrent activity followed by C. eucalyptusa and cv.…”

Exploration of Clove Bud (Syzygium aromaticum) Essential Oil as a Novel Attractant against Bactrocera dorsalis (Hendel) and Its Safety Evaluation

“…In addition, a study on olfactory behaviour responses found that clove oil at a 5% concentration is strongly attractive to Bactrocera zonata (Saunders) adults [ 22 ]. Moreover, Ali et al [ 23 ] reported that clove essential oils exhibited insecticidal activity against B. zonata pupa. Thus, in conjunction with other sustainable pest management strategies, EOs can be an effective alternative to conventional plant protection products.…”
