“…Furthermore, the plant-derived insecticidal activity could be developed into products suitable for integrated pest management as they are selective to pests and ecofriendly. It can be applied to all crops in different agricultural systems (Arnason et al, 1989;Schmutterer, 1992;Burks et al, 2000;Enan, 2004;Prabakar and Jebanesan, 2004;Rani, 2012;Tu et al, 2018;Fouad et al, 2021 andAdesina, 2022).…”

“…Recently, scientists has paid attention towards plant products as novel and effective materials in plant protection as it consider non phytotoxicity, easy biodegradability and ecofriendly. The plant products and the botanical pesticides are being used globally as Fumigants and green pesticides (Dubey et al, 2008;Jayakumar et al, 2017;Tu et al, 2018 andAdesina 2022), they are biologically active, not absorbed by grain, not flammable, high volatility and toxicity to storedgrain insect pests (Shaaya et al, 1997 andFouad et al, 2021). The fumigation with traditional insecticides, methyl bromide phosphine has been argued to be genotoxic to human and animals (Garry et al, 1989;WMO, 1991;Chaudhry, 1995 andFields andWhite, 2002).…”

Cereal grains considered one of the most important crops in Egypt and all over the world, these stored grains are infested with many insects that reduce their economic value and cause a significant problem for food security. The current study aimed to protect stored grains from infestation of different weevil species using plant oils as fumigants. Six plant volatile oils i.e., Garlic, Clove, Peppermint, Orange, Onion, and Camphor were used to determine the fumigant toxicity of oils the adults of Sitophilus granaries, Sitophilus zeamais and Sitophilus oryzae, as well as, percentages of total protein and total carbohydrates were determined in both healthy and infested seeds. The results indicated that Camphor 2.0 %, Orang 2% and Peppermint 2.0 %, respectively, were the most effective oils against the tested insects. The number of died Sitophilus granaries per 80 insects reached 74, 73 and 70 insect for Camphor 2.0 %, Orang 2% and Peppermint 2.0 %, respectively, after 10 day of application, while in S. zeamais were 72, 73 and 70 insect, respectively. The number of died S. oryzae per 80 insects recorded 78, 77 and 74 insect, respectively. The results also showed that the total protein and total carbohydrates were greatly affected by the infestation of insects. Finally, the fumigation with plant essential oils could be used as safe insecticide against stored product insects alternative to chemical pesticides.

“…These mechanisms involve the production of compounds that interfere with insects’ usual physiological and behavioral processes. As a result, these compounds impact various aspects of insect life, such as feeding, mating, mortality, and egg-laying (Adesina, 2022). Plant-based insecticides are highly regarded as cost-effective and environmentally friendly options for safeguarding plants and stored grains.…”

Insecticides derived from plants provide environmentally friendly and sustainable options as alternatives to synthetic chemicals. This investigation delves into the insecticidal capabilities of two distinct Datura species, namely, Datura alba and Datura stramonium, in combatting significant pests such asSpodoptera litura, Bemesia tabaci, andCallosobruchus maculatus. Datura plants have a well-documented history of medicinal use and are recognized for their abundant Tropane alkaloid content, which acts as an innate defense mechanism against pests. Hence, the current investigation involved the extraction of chemical compounds from the leaves, flowers, seeds, and roots of both Datura stramonium and Datura alba. Subsequently, these extracts were assessed for efficacy using Spodoptera litura larvae, Bemesia tabaci, andCallosobruchus maculatusin bioassays. The larvicidal experiments encompassed a range of concentrations (3%, 5%, 10%), with larval mortality being documented at multiple time intervals: 6, 12, 24, 48, and 72 hours. The findings from our investigation uncover the notable insecticidal attributes of root, leaf, flower, and seed extracts from bothDatura albaandDatura stramoniumagainst these larvae. These extracts demonstrated distinct mortality rates at various concentrations and exposure durations. This comprehensive analysis imparts crucial knowledge regarding the insecticidal qualities of Datura species and their prospective contributions to sustainable pest control practices. The observed effectiveness of these plant extracts against a spectrum of significant pests hints at their potential as ecological alternatives within integrated pest management strategies.

“…Botanical insecticides contain a range of bioactive compounds that have potential to cause adverse effects on organisms that either consume them or are exposed to them. In particular, plants have co-evolved with insects that eat them, so they have developed defense mechanisms, including production of compounds that disrupt normal physiology and behavior of insects, thus, affecting eating, mating, mortalities and oviposition [23]. Secondary metabolites, N. tabacum and N. rustica, including alkaliods, flavoniods, saponins and di-tarphene can repel or kill insects.…”

Plant based insecticides are considered among the most economic and ecofriendly chemicals for the protection of plants and stored grains. The cowpea weevil (Callosbruchus maculatus) causes more than 90% damage to sored grains in three to six months. The current study investigates insecticidal potentials of five selected botanicals: Melia azedarach, Nicotiana rustica, Azadirachta indica, Nicotiana tabacum and Thuja orientalis. They are explored at six different concentrations (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0%) against C. maculatus and compared to effects of distilled water which is used as a control. Toxicities of 3%(V/V) extracts of N. tabacum, N. rustica, A. indica and T. orientalis against C. maculatus were 100%, 86.11%, 80.56% and 72.22%, respectively. Maximum mortality was caused by N. tabacum and N. rustica (100%), followed by A. indica (82%), whereas minimum mortality was observed in T. orientalis (64%) at 2.5%. Several phytochemicals, alkaloids, saponins, diterphenes, phytosterol, flavonoids and phenols were identified in N. tabacum and N. rustica, while few were present in A. indica. Phytosterol was present in greatest abundance. Saponins were only detected in aqueous extracts of N. rustica and N. tabacum. Taken together, these results indicate the utility of N. tabacum, N. rustica and A. indica as potential botanicals to control pest beetle and cowpea weevil.
