“…Likewise, the egg-hatching, growth rate, oviposition, and feeding rates decrease with higher concentrations of the ethanolic extract. Moawad and Sadek [ 16 ] reported that a 10% ( v / v ) concentration rate of M. oleifera oil kills 66 and 76% of the first and third larval instars of Spodoptera littoralis in 24 h. Kamel [ 15 ] found that an increase in the mortality (42.2–100%) of Spodoptera frugiperda was due to the concentration rates (1.25–10% ( v / v )) of M. oleifera oil. On the other hand, Adenekan et al [ 25 ] reported that pulverized leaves and stems of M. oleifera (0.5 g of powder with 30 g of cowpea seeds, Vigna unguiculata Walp (Fabaceae)) caused 85% and 70% mortality in Callsobruchus maculatus after 24 h. On the other hand, Ojo et al [ 17 ] reported that 2 g of M. oleifera leaf powder with 20 g of cowpea seeds led to 36.33% mortality in Callosobruchus maculatus .…”

“…In this research work, the number of T. merganser hatched eggs decreased according to the concentration increase, indicating that all the concentration rates have residual toxic effect on the eggs laid and/or on T. merganser females’ biology, and have a negative effect on the growth rate (r i ) of the red spider mite. Moawad and Sadek [ 16 ] reported that M. oleifera oil concentrations of 5, 7.5, and 10% ( v / v ) reduce the egg viability of cotton leaf worm, Spodoptera littoralis , by 50.07, 75.41, and 88.90, respectively, as compared to the control. Derbalah et al [ 27 ] mentioned that the bioactive compounds with egg-killing effect affect the embryo formation and the developing larvae within the egg’s membrane, before hatching.…”

“…Several research works have reported the insect pest control properties of M. oleifera . Furthermore, M. oleifera oils have shown to produce an anti-feeding effect on Spodoptera frugiperda Walker larvae (Lepidoptera: Noctuidae) [ 15 ] and Spodoptera littoralis Boisd (Lepidoptera: Noctuidae) [ 16 ]. The leaf powder of M. oleifera produces anti-egg-laying activity on Callosobruchus maculatus F. (Coleoptera: Chrysomelidae) [ 17 ] and Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) [ 18 ].…”

The Tetranychidae family includes mites causing severe damage to agricultural fields. The red spider mite, Tetranychus merganser Boudreaux (Acari: Tetranychidae), causes severe damage to several plant species grown as cash crops. Current red spider mite control depends mainly on chemical insecticides. There is a need for alternate control measures that are environmentally friendlier than chemical pesticides. The aim of the study was to assess the effects of Moringa oleifera leaf ethanolic extract at different concentrations (0.1, 0.5, 1, 5, 10, 15, and 20% (v/v)) against T. merganser females. Such effects can serve as a basis to include this compound in integrated pest management programs for the control of red spider mites. Mites treated with 20% (v/v) killed 86.67%, 13.70%, and 96.30% at 24, 48, and 72 h, respectively, as compared to the control treatment. Oviposition, egg hatching, and the damage caused by red spider mites were all reduced at high concentrations. Moringa oleifera leaf ethanolic extract can be used as a powerful bioacaricide for the control of T. merganser.

“…The leaf powder from M. oleifera has anti-egg-laying activity over Callosobruchus maculatus F. (Coleoptera: Chrysomelidae) and Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) [8]. Likewise, M. oleifera oil has anti-feeding properties over Spodoptera littoralis Boisd larvae (Lepidoptera: Noctuidae) [9] and S. frugiperda Walker (Lepidoptera: Noctuidae) [10]. Furthermore, the lectins in M. oleifera seeds have larvicidal effect over the developing instars of Aedes aegypti mosquito L. (Diptera: Culicidae) [11] and over the Mediterranean flour moth Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) [12].…”

Tetranychidae family is a major group of mites causing serious damage in agricultural, vegetable and ornamental crops. Avocado bronze mite (ABM), Oligonychus punicae Hirst (Acari: Tetranychidae) causes major crop damage, defoliation and fruit abortion. At present, the control of this mite depends mainly on agrochemicals. Therefore it is necessary to find alternatives to synthetic pesticides that can help minimize environmental impact and health risks for the consumers. The aim of this research was to assess the effect of different concentrations (0.1, 0.5, 1, 5, 10, 15 and 20% (v/v)) of ethanolic extract of Moringa oleifera leaves against adult ABM females. Mites treated with 0.1 and 20% (v/v) of the extract showed mortality of 0.00% and 46.67%, 6.67% and 86.67%, 13.70% and 96.67%, at 24, 48 and 72 h, as compared to the control treatment, respectively. The number of eggs laid and hatch, as well as ABM feeding rates, depended on the extract concentration, which led to a reduction in the growth rate. M. oleifera leaf ethanolic extract has potential to control O. punicae.

“…They can alter activities of digestive enzymes, transmission enzyme (acetylcholinesterase) and detoxifying proteins such as glutathione-Stransferases. Plant oils can also act by interfering with insect growth and development, behaviour and fitness (Moawad and Sadek, 2018). These changes have been attributed to the presence of alkaloids, steroids, anthraquinones, flavonoides, tannins, polyphenyls and terpenes in essential oils (EOs).…”

Insecticidal activities of hexane extracts of leaves and roots of siam weed and vetiver, and roots of neem were assessed against house fly, Musca domestica L. Mortality test was conducted using serial concentrations 20%, 10%, 5% and 2.5% of extracted oils while behavioural orientation of house fly to oil odour, antioviposition effect of oil toward the insects, biochemical reactions in treated flies and fitness of offspring were determined using 20% oil concentration. House fly mortality varied significantly with plant species and part of plant extracted (P < 0.001), concentration applied (P < 0.001) and time post-exposure (P < 0.001). All tested plant extracts showed potential as good control agents with average mortality ranging from 59-74%. However, significantly lower median lethal values (LC50 and LT50) separated vetiver as the most toxic plant against the insect pest. The plant oils repelled house flies (93-100%), reduced the number of larvae that hatched from laid eggs, lowered adult emergence and caused a significant reduction in size and weight of offspring. On the contrary, exposure to plant oils did not alter offspring sex ratio. In comparison to untreated house flies, plant oils induced biochemical stress in poisoned cohorts as evidenced in significant deviation of digestive enzyme (α- and β- amylases, lipase) activity and concentrations of detoxifying enzyme (glutathione-Stransferase), neurochemical enzyme (acetylcholinesterase) and energy metabolism biomolecules (total protein). Implications of obtained results for non-chemical control strategies are discussed.
