“…Further, if the extract was initially defatted with hexane, the LC50 was found to be 74.68 μg/mL, and the instar stage of the mosquito larvae was irrelevant (Morales et al, 2004). Therefore, our results are more similar to the results of Bobadilla (2005) and Morales (2004). However, the activity of the A. muricata ethanol extracts against Artemia salina resulted in an LC50 of 0.49 μg/mL for the leaves and 210 μg/mL for the seeds (Luna et al, 2006;Rojas et al, 2004).…”

“…Two previous reports measured an LC50 of 60 (50-70) and 900 (380-1300) μg/mL, respectively, for A. muricata extracts toward the 4 th instar A. aegypti larvae (Bobadilla et al, 2005;Henao et al, 2007). Further, if the extract was initially defatted with hexane, the LC50 was found to be 74.68 μg/mL, and the instar stage of the mosquito larvae was irrelevant (Morales et al, 2004).…”

Amongst other botanical sources, Annona muricata L., Annonaceae, seeds and Piper nigrum L., Piperaceae, fruits are particularly enriched with acetogenins and piperine-related amides, respectively. These crude ethanolic extracts are potent bioactives that can kill Aedes aegypti larvae (dengue fever mosquito). A. muricata displayed a 93.48 μg/mL LC50 and P. nigrum an 1.84 μg/mL LC50. An uncommon pharmacognostical/toxicological approach was used, namely different combinations of both extracts to achieve an improved lethal effect on the larvae. The independence test (χ²) was utilized to evaluate the combination of the two crude extracts. All of the tested combinations behaved synergistically and these novel results were attributed to the completely different biochemical mechanisms of the differentiated chemical substances that were present in the two botanical sources. Besides the two above selected plants, Melia azedarach L., Meliaceae, Origanum vulgare L., Lamiaceae, and Ilex paraguariensis A. St.-Hil., Aquifoliaceae, in order of decreasing toxicity, may also be sought as potential extracts for the sake of synergic combinations.

“…In the present study, both the employed solvents showed distinct polarities for the extraction of A. vepretorum compounds.Therefore, it was assumed that the acetogenins varied from being very polar -when extracted by water, ethyl alcohol, and methanol -, to being nonpolar when extracted by hexane (Bobadilla et al, 2005). However, there are evidences that extracts obtained with solvents having low and medium polarity are more efficient.…”

-The objective of this work was to evaluate the lethal and sublethal toxicity of hexane and methanolic extracts from the leaves of Annona vepretorum (Annonaceae) on Tetranychus urticae (Acari: Tetranychidae). The methanolic extract toxicity was evaluated by Potter tower application (topical + residual effect) and by immersion of Canavalia ensiformis leaf disks in the extract solution (residual contact effect). The hexane extract toxicity was evaluated exclusively through residual contact effect. Sublethal effects of the methanolic extract were evaluated through LC 50 on the females. Mite preference for feeding and oviposition was evaluated by multiple choice tests, between the control and the extract concentrations, using the hexane and methanolic extracts. Estimated LC 50 for the methanolic extract was 10.96 mg mL -1 for the topic + residual effect and 22.07 mg mL -1 for the residual effect. Estimated LC 50 for the hexane extract was 50.61 mg mL -1. The methanolic extract at the previously estimated CL 50 interfered in the fecundity and longevity of females, differing significantly from the control treatment. In the multiple choice tests, for both extracts, mites showed a significant preference for the control, both for feeding and oviposition. Annona vepretorum has acaricide effect and constitutes a botanical source with great potential for controlling T. urticae.Index terms: acetogenins, botanical acaricide, botanical extracts, integrated pest management, pesticide resistance, two-spotted spider mite. Bioatividade de extratos orgânicos de Annona vepretorumsobre Tetranychus urticae (Acari: Tetranychidae)Resumo -O objetivo deste trabalho foi avaliar a toxicidade letal e subletal dos extratos hexânico e metanólico das folhas de Annona vepretorum (Annonaceae) sobre Tetranychus urticae (Acari: Tetranychidae). A toxicidade do extrato metanólico foi avaliada por meio da aplicação em torre de Potter (efeito tópico + residual) e por imersão de discos de folhas de Canavalia ensiformis na solução do extrato (efeito de contato residual). A toxicidade do extrato hexânico foi avaliada unicamente por meio do efeito de contato residual. Os efeitos subletais do extrato metanólico foram avaliados por meio da CL 50 sobre as fêmeas. A preferência do ácaro por alimentação e oviposição foi avaliada por testes de múltipla escolha, entre o tratamento controle e as concentrações dos extratos, com os extratos hexânico e metanólico. A CL 50 estimada do extrato metanólico foi de 10,96 mg mL -1 para o efeito tópico + residual e de 22,07 mg mL -1 para o efeito residual. A CL 50 estimada para o extrato hexânico foi de 50,61 mg mL -1. O extrato metanólico na CL 50 previamente estimada interferiu na fecundidade e na longevidade das fêmeas e diferiu significativamente do tratamento controle. Nos testes com múltipla escolha, para ambos os extratos, os ácaros apresentaram preferência significativa pelo controle, quanto à alimentação e à oviposição.

“…Kotkar et al (2002) considered the phenolic compounds to be phytochemicals with insecticidal activity, based on the action of their hydroxyl groups against the larval enzyme systems (VALENCIA, 1995), which are enzyme systems similar to those involved in the respiratory chain, causing potent inhibition (BOBADILLA, 2005).…”

ABSTRACT:In the search for alternative ways to control Aedes aegypti with minimal environmental impact and in a manner that preserves human health, this study sought to evaluate the larvicidal effect of the invasive and antioxidant Spermacoce latifolia plant by performing a phytochemical study. Phytochemical screenings were done according to characterization reactions and thin layer chromatography. Phenolics compounds content (Folin-Ciocalteu's) and flavonoids (AlCl 3 ) spectrophotometric was performed, and the antioxidant activity was determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH). The phytochemical results revealed the presence of phenolic, flavonoid, tannin, steroid, free triterpene, coumarin, and alkaloid compounds. The content of total phenols (TPs) (482.7 ± 1.8 mg mgGA g -1 ) and flavonoids (165.4 ± 1.5 mg QE g -1 ) accounted for the antioxidant activity of 150 µg mL -1 methanolic extract. In the proposed bioassays, groups of 25 third-stage larvae were challenged at different concentrations of plant crude extract (1.0, 0.5, 0.25, and 0.1 mg mL -1 ) of weight per volume in four replicates. In multiple concentration tests, the concentrations were selected to range from 0 % to 100 % mortality after 24 hours of contact with the solution. Toxicity was defined as the inhibition or total inactivity of the larvae. It was concluded that the methanol extract had an LC 50 of 0.625 mg mL -1 , indicating its potential use as a larvicide against A. aegypti and linking its activity to its phenolic and flavonoid components.
