Using ichthyotoxic plants as bioinsecticide: A literature review

Abstract

Some ichthyotoxic plants are study object aiming to discover promising substances in the field of Biotechnology, in search of plant extracts which can be used or even transformed into natural insecticides. This paper presents a bibliographical survey in order to check the traditional use of ichthyotoxic plants as bioinsecticide. Among the plants identified as ichthyotoxic, the most cited in traditional use are those from the genera Derris, Serjania, Lonchocarpus, Magonia, and Tephrosia. The survey suggests that ichthyotoxic plant extracts can contain classes of chemical compounds such as isoflavonoids and tannins with a bioinsecticidal effect and, thus, they can be used in Biotechnology, contributing to reduce the use of synthetic insecticides that present a high toxicity level.Keywords: ichthyotoxic plants, bioinsecticide, plant extracts, biotechnology. RESUMO: Uso de plantas ictiotóxicas como bioinseticida: revisão de literatura. Algumas plantas ictiotóxicas são objeto de estudos com a finalidade de descobrir substâncias promissoras no campo da Biotecnologia, na busca de extratos vegetais que possam ser usados ou mesmo transformados em inseticidas naturais. Esse artigo apresenta uma pesquisa bibliográfica sobre o uso tradicional de plantas ictiotóxicas como bioinseticida. Entre as plantas identificadas como ictiotóxicas, as mais citadas no uso tradicional são as dos gêneros Derris, Serjania, Lonchocarpus, Magonia e Tephrosia. A pesquisa sugere que extratos de plantas ictiotóxicas podem conter classes de compostos químicos, como isoflavonoides e taninos, com efeito bioinseticida e, assim, podem ser usados na Biotecnologia, contribuindo na redução do uso de inseticidas sintéticos que possuem alto nível de toxicidade.

Efeito de extratos aquosos de Serjania spp. sobre a oviposição de Plutella xylostella L. (Lepidoptera: Plutellidae)

“…Nos bioensaios realizados ambas espécies vegetais apresentaram resultados semelhantes, reduzindo a fecundidade, o número de larvas e a viabilidade dos ovos, pois estas espécies pertencem ao mesmo gênero botânico (Serjania) e, possivelmente, compartilham substâncias inseticidas e características ictiotóxicas semelhantes (Quintanilha & Pinto, 2014;Andrade et al, 2015;Périco et al, 2015).…”

Experimental Phase Equilibrium Data for Rotenone in Supercritical Carbon Dioxide

“…Rotenone (C 23 H 22 O 6 , CASRN 83-79-4) is an odorless organic molecule that has insecticidal, piscicidal, and pesticidal properties. Rotenone can be extracted from tropical plants such as Derris elliptica, D. amazonica, Amorpha fruticosa , and Tephrosia vogelii . − In Brazil, species of the genus Derris , vine plants that reach the crowns of trees, are popularly known as timbó. ,, In Amazonia, fishermen use timbó to catch fish from rivers. The timbó stuns the fish, and their breathing is paralyzed, resulting in their capture when they rise to the surface of the water in search of oxygen. − , …”

“…The timbóstuns the fish, and their breathing is paralyzed, resulting in their capture when they rise to the surface of the water in search of oxygen. [5][6][7]6 Rotenone is also used in powdered form to treat scabies and head lice in humans, as well as parasitic mites on chickens, livestock, and pet animals. 2,4,6 It is also used to reduce or eradicate invader fish populations.…”
