This study investigates updated information in different search engines on the distribution, phytochemistry, pharmacology, and toxicology of Brugmansia suaveolens (Solanaceae) using the extracts or chemical compounds at present. This plant has been used in traditional medicine in different cultures as a hallucinatory, analgesic, aphrodisiac, nematicide, sleep inducer, and muscle relaxant, as well as a treatment for rheumatism, asthma, and inflammation. The flowers, fruits, stems, and roots of the plant are used, and different chemical compounds have been identified, such as alkaloids, volatile compounds (mainly terpenes), coumarins, flavonoids, steroids, and hydrocarbons. The concentration of the different compounds varies according to the biotic and abiotic factors to which the plant is exposed. The toxic effect of the plant is mainly attributed to atropine and scopolamine, their averages in the flowers are 0.79 ± 0.03 and 0.72 ± 0.05 mg/g of dry plant, respectively. Pharmacological studies have shown that an aqueous extract exhibits the antinociceptive effect, at doses of 100 and 300 mg/kg i.p. in mice. On the other hand, the ethanolic extract at 1000 mg/L, showed a nematocidal activity in vitro of 64% against Meloidogyne incognita in 72 h. Likewise, it showed a 100% larvicidal activity at 12.5 mg/L against Ancylostoma spp. In another study, the lethal activity of shrimp in brine from an ethanolic extract showed an LC50 of 106 µg/mL at double serial concentrations of 1000–0 (µg/mL). Although there are pharmacological and phytochemical studies in the plant, they are still scarce, which has potential for the examination of the biological activity of the more than one hundred compounds that have been reported, many of which have not been evaluated.

“…The available publications have concerned the activity of mixtures containing B. thuringiensis crystals and extract oils against insect pests (Abedi, Saber, Vojoudi, Mahdavi, & Parsaeyan, ; Aggarwal, Holaschke, & Basedow, ; Amizadeh, Hejazi, Niknam, & Arzanlou, ; Mansour, Foda, & Aly, ; Nouri‐Ganbalani, Borzoui, Abdolmaleki, Abedi, & Kamita, ; Rajguru & Sharma, ; Subramaniam, Murugan, & Kovendan, ; Vilani et al, ). The mortality of lepidopteran insects Helicoverpa armigera and Spodoptera exigua was higher when the mixture of NeemAzal containing azadirachtin and a pesticide with bacterial spores and crystals was applied than the mortality of insects caused by each preparation separately (Aggarwal et al, ).…”

The main purpose of this study was to determine the insecticidal activity of mixtures of Bacillus thuringiensis crystalline toxins and plant substances that could contribute to create a new bioinsecticide of high efficiency. We decided to determine the toxicity of crystals of B. thuringiensis MPU B9 isolate, azadirachtin (NeemAzal), mustard oil and their mixtures against lepidopteran pests: Cydia pomonella, Spodoptera exigua and Dendrolimus pini. The interaction of the components in mixtures against insects was evaluated and their utility in plant protection was assessed. The crystals and plant substances showed synergistic effect against all insect species. The occurrence of synergism between two components depended on the ratio of their concentration in mixtures. Slight amount of one of the components added to the mixture led to enhanced toxicity of the preparation. The supplementation of mustard oil with B. thuringiensis toxins from up to 0.3% of the mixture resulted in more than twofold higher observed mortality of L1 larvae of D. pini in comparison with expected mortality. The beneficial insecticidal effect of the mustard oil and crystals mixture was also noted when crystals comprised up to 1.3% and from 7 to 20% against L1 caterpillars of C. pomonella and L3 larvae of S. exigua, respectively. The insecticidal efficient effect was achieved when mixture of B. thuringiensis crystals and azadirachtin was used against the three species of lepidopteran pests. The combinations in which components interacted synergistically against caterpillars are potentially useful for making a new bioinsecticide for controlling lepidopteran pests in plant protection.
