“…Another species of agave, Agave sisalana , has been shown to control ants (Barbosa, Silva, & Carvalho, ; Pérez López, ), mites and caterpillars such as Spodoptera frugiperda in maize (Botti et al, ; Cerqueira, Osuna, & Costa, ; Luria et al, ). Agave tequilana extracts were efficient to kill the whitefly ( Bemisia tabaci) , also a Hemiptera, and the nematode Panagrellus redivivus (Herbert‐Doctor, Saavedra‐Aguilar, Villarreal, Cardoso‐Taketa, & Vite‐Vallejo, ).…”

Alternative methods of pest control can and should be encouraged, especially those that consider the reality of smallholder family farmers. Here, we evaluated the potential of Agave americana (agave) extracts for the control of the aphid Brevicoryne brassicae in cabbage (Brassica oleracea L. var acephala) in the field and laboratory. The field experiments consisted of the evaluation of the proportion of dead aphids on cabbage plants after application of agave extracts. In the field, agave mixed with cow milk caused mortality above 80% and was the most effective extract. Agave mixed with water and agave mixed with ethanol elicited mortality above 60%. In the laboratory, we evaluated the mortality of aphids after the application of different concentrations of aqueous agave extracts; the commercial insecticide deltamethrin was included as positive control. Evaluation took place at 3, 6, 12, 24, 48 and 72 hr after applying the treatment. As expected, deltamethrin was the most effective treatment. However, agave extract at concentrations of 0.750 and 0.500 g/mL caused >70% mortality 3 hr after application. We conclude that A. americana extracts decreased aphid populations and is a promising alternative to the commercial insecticide against aphids in cabbage.

“…Classical chemical tests for screening alkaloids, anthracene derivatives, coumarins, flavonoids, saponins, steroids, terpenes, and tannins were performed on the hydroalcoholic extracts using standard procedures reported by Wagner and Bladt [21], Harborne [22], Bruneton [23], Carvajal-Rojas et al [24], Tiwari et al [25], Herbert et al [26], and Rivas-Morales et al [27].…”

Phytochemical composition, antioxidant, and toxic effects of two orchid (Prosthechea cochleata and Prosthechea livida) were examined in their different hexane and dichloromethane/methanol extracts of leaves, pseudobulbs, rhizome and roots. Phytochemical screening reveals the presence of alkaloids, coumarins, flavonoids, saponins, steroids and terpenes except for anthracene derivatives in P. livida and tannins in both species. Results showed exhibited significant toxicity against brine shrimp with an LC50 values ranged from 3 to 54 µg/ml in 24 h. Finally, the results of the antioxidant test in yeast (Saccharomyces cerevisiae) showed that CH2Cl2:MeOH extract of P. cochleata root extract presented the most efficient protective antioxidant percentage (%PA), with 20 µg/mL, displaying a cell viability of 68.58%. In P. livida case, rhizome extract presented the most efficient %PA, with 1000 µg/mL, with a cell viability of 65.82%. The results evidenced the toxicity of Prosthechea cochleata and Prosthechea livida and reveals potential antioxidative of extracts.

“…The toxic effects of the aqueous extracts of native plants were similar to those of A. indica aqueous extracts (LC 50 = 0.30%, w / v ) and were greater than those of the A. indica ethanolic extract against eggs (LC 50 = 3.60 mg/mL) and nymphs (LC 50 = 2.57 mg/mL). A. tequilana juice (undiluted) and its hexanic extract (2%) promoted B. tabaci nymph mortality (100% and 91%, respectively), which is interesting given the significant quantities of juice obtained from the waste of this agave ( Table 11 ) [ 58 ].…”

Insecticidal and Nematicidal Contributions of Mexican Flora in the Search for Safer Biopesticides

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.
