“…The laboratory tests showed that the fumigant toxicity of 24 essential oils from lemon eucalyptus was effective against females of T. urticae menthol being the maximum toxic compound, followed by citronellyl acetate [95]. The two eucalyptus essential oils, specifically Eucalyptus lehmani and Eucalyptus astringens, showed a positive effect against strains from Tunisia and Algeria of three stocked beetles: Rhyzopertha dominica, Callosobruchus maculatus, and Tribolium castaneum [96]. In Tunisia, the ten principal constituents of Deverra scoparia oil were individually tested against T. urticae females.…”

Current Situation of Tetranychus urticae (Acari: Tetranychidae) in Northern Africa: The Sustainable Control Methods and Priorities for Future Research

In North Africa, Tetranychus urticae Koch, 1836 represents one of the most destructive generalists among mite herbivores. Unfortunately, it is a source of important annual casualties in crop production. It is a phytophagous mite that can feed on hundreds of host plants and produces significant damage. The control of T. urticae in North Africa has been principally based on acaricide sprays. However, new alternative methods have shown effective results, such as artificial ultraviolet-B, natural enemies, and the introduction of new genetic methods. This review aims to present a synthesis of information surrounding control methods of T. urticae in North Africa. We highlight the principal findings of previous studies. Then, we discuss current control methods and propose new innovative research and sustainable approaches to controlling this pest. The control method can potentially extrapolate in North African regions due to its positive ecological results. Further, studies proved the use of natural enemies, myco-metabolites, bacteria metabolites, and the introduction of a genetic method in an integrated long-term sustainable program that can successfully defeat the populations of T. urticae. We also discuss high-priority research guidelines to investigate new sustainable management strategies. Setting up an integrated long-term ecological monitoring program in different Northwest African countries and incorporating new technologies into monitoring programs is an urgent need to fight this devastating pest.

Encapsulation of Rosmarinus officinalis essential oil (EO) on chitosan and gum Arabic matrix were prepared at different ratios with various concentrations of essential oil. The capsules were characterized by their encapsulation efficacy (EE%) and loading capacity (LC%). The cumulative release profiles were evaluated by UV/Vis spectroscopy. The chemical compounds for free and encapsulated essential oil were determined by GC-MS technique and the insecticidal toxicity against Tribolium castaneum and Oryzeaphilus surrinamensis was determined by fumigant bioassays. Results showed that capsules with ratio chitosan: gum arabic: EO (1: 1: 0.5) revealed the highest EE (45.8%) and LC (2.31%). In vitro release profiles demonstrated that encapsulated essential oil showed a sustained release especially for the ratio with high EO concentration. The major constituents of the rosemary essential oil were 1,8-cineole (39.67%), Camphor (18.04%), followed by borneol (10.52%) and α-Pinene (6.33%). After encapsulation numerous minor compounds have been missing during storage periods until identifying only 1, 8-cineole, α-terpineol and camphor after 60 days of storage. The fumigant tests demonstrated that encapsulated EO exhibited an effective control against insect pest during storage periods namely 30, 45, 60 days with 99%, 66%, 46% for T. castaneum and 100%, 84%, 82% for O. surrinamensis. This work supports the hypothesis that major essential oil components were responsible for its pesticidal activities over storage. Besides, toxicities against T. castaneum and O. surinamensis adults was mainly attributed to 1, 8-cineole.

“…In addition, there have been several investigations into the evaluation of the pesticidal properties of essential oils extracted from many species of the genus Eucalyptus in recent years [24][25][26] ; the insecticidal potential of E. camaldulensis and E. viminalis has also been investigated against some stored-product insect pests. For example, the fumigant toxicity of Eucalyptus intertexta R.T. Baker, Eucalyptus sargentii Maiden, and E. camaldulensis essential oils against the adults of Callosobruchus maculatus (Fab.…”

The use of synthetic chemicals, with harmful effects on the environment and human health, is the principal strategy in the management of stored-product insect pests such as Oryzaephilus surinamensis and Sitophilus oryzae. Various studies in recent years have highlighted the possibility of using plant essential oils as available and low-risk factors in insect pest management. Therefore, in the present study, the possibility of controlling O. surinamensis and S. oryzae was investigated using Eucalyptus camaldulensis and Eucalyptus viminalis leaf essential oils. The essential oils were obtained by hydrodistillation of the leaves of the 2 Eucalyptus species, and the chemical compositions were determined by gas chromatographic-mass spectral analysis. The essential oil of E. camaldulensis was dominated by p-cymene (24.8%), cryptone (18.9%), and spathulenol (12.4%), while the major components in E. viminalis essential oil were 1,8-cineole (51.6%) and α-pinene (15.8%). The essential oils displayed promising fumigant toxicity against insect pests, which was positively dependent on utilized concentrations and exposure times. Oryzaephilus surinamensis, with low median lethal concentrations, was more susceptible than S. oryzae to the essential oils after 24, 48, and 72 hours. Also, E. viminalis essential oil, with a high level of insecticidal monoterpenes such as 1,8-cineole and α-pinene, was more toxic to insect pests than E. camaldulensis oil. According to the results of the current study, E. camaldulensis and E. viminalis essential oils, rich in insecticidal terpenes, can be alternative candidates to synthetic chemicals in the management of O. surinamensis and S. oryzae.
