“…Hexane and acetone extracts from A. mexicana seeds and hexane extracts from the bark of P . perniciosum showed the lowest larvicidal activities, with LC 50 values of, 80, 50, and 20 µg/mL, respectively [ 51 ]. Other organic extracts observed to have larvicidal activity against A. aegypti include those of R. chalepensis , T. vulgaris , and Z. fagara , exhibiting notable LC 50 values of 1.8, 4.4 and 75.1 µg/mL, respectively [ 52 ].…”

Plant metabolites have been used for many years to control pests in animals and to protect crops. Here, we reviewed the available literature, looking for the species of Mexican flora for which extracts and metabolites have shown activity against pest insects and parasitic nematodes of agricultural importance, as well as against nematodes that parasitize domestic cattle. From 1996 to 2018, the search for novel and eco-friendly biopesticides has resulted in the identification of 114 species belonging to 36 botanical families of Mexican plants with reported biological effects on 20 insect species and seven nematode species. Most plant species with detected pesticide properties belong to the families Asteraceae, Fabaceae, and Lamiaceae. Eighty-six metabolites have been identified as pesticidal active principles, and most have been terpenoids. Therefore, the continuation and intensification of this area of research is very important to contribute to the generation of new products that will provide alternatives to conventional pesticide agents. In addition, future studies will contribute to the recognition and dissemination of the importance of propagating plant species for their conservation and sustainable use.

Objectives: The present study was conducted to determine antimicrobial, antiradical, and insecticidal activity of methanolic extract of the whole plant of Solanum virginianum L. (Solanaceae).Methods: Extraction of shade dried and powdered plant material was carried out by maceration process. Antibacterial and antifungal activities of extract were determined by agar well diffusion and poisoned food technique, respectively. Antiradical activity of extract was assessed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2-azinobis 3-ethylbenzothiazoline 6-sulfonate (ABTS) free radical scavenging assays. Insecticidal activity, in terms of larvicidal activity, was evaluated against 2 nd and 3 rd instar larvae of Aedes aegypti. Results:The extract exhibited inhibitory activity against all bacteria. Gram-positive bacteria showed greater susceptibility to extract when compared to Gram-negative bacteria. The extract was effective in inhibiting the mycelial growth of all test fungi with marked activity against Curvularia sp. and Alternaria sp. The extract scavenged DPPH and ABTS radicals dose dependently with an inhibitory concentration value of 45.66 and 7.37µg/ml, respectively. The extract showed concentration-dependent larvicidal activity with high lethal activity observed against 2 nd instar larvae with lethal concentration value of 0.82 mg/ml. Conclusion:In suitable form, the plant can be used as an effective agent against microbial infections and oxidative damage and to control insect vectors which transmit several diseases.

“…For example, Argemone mexicana has demon-strated to have a significant insecticidal activity against the mosquito Aedes aegypti (Diptera : Culicidae). [29][30][31][32][33] Similarly, diverse organic extracts of the same plant have been evaluated as insecticides against Culex quinquefasciatus, finding that A. mexicana is an effective alternative for the biocontrol of this kind of mosquito. [34][35][36] On the other hand, Malarvannan studied the active effects of the extracts of A. mexicana against Helicoverpa armigera (Lepidoptera : Noctuidae).…”

For years, crop protection from pest attack, has been dominated by the use of synthetic insecticides. However, many of them can cause severe environmental problems and human health. In this context, the use of plant extracts constitutes an alternative to avoid this kind of contaminants. In this work, we investigated the chemical constituents and insecticidal activity of different extracts of leaves and stems of Argemone ochroleuca Sweet (Papaveraceae) against three economically important pests Sitophilos zeamais (Coleoptera:Curculionidae), Galleria mellonella (Lepidoptera:Pyralidae) and Xyleborus ferrugineus (Coleoptera:Scolytidae). A GC‐MS analysis mostly revealed the presence benzylisoquinoline alkaloids such as allocryptopine, protopine, among others. For the insecticidal activity, after nine hours of contact, the methanolic leaves extract showed a 100% of mortality, followed by the dichloromethane stems extract with up to 93% of mortality. The results suggest that the benzylisoquinoline alkaloids are involved in the insecticidal activity through the octopaminergic system of the tested insects.
