“…The use of botanical pesticides could present a safe alternative compared to the use of broad spectrum chemical insecticides in crop protection [12, 13]. In nature, plants produce secondary metabolites during their interaction with insects and these metabolites can act as toxicants [14], antifeedants [15], anti-oviposition agents and deterrents towards insects [16]. Because of such wide insecticidal properties, the study of secondary metabolites and the development of new potent formulations based on them have become increasingly important.…”

Bioactivity-guided isolation of rosmarinic acid as the principle bioactive compound from the butanol extract of Isodon rugosus against the pea aphid, Acyrthosiphon pisum

Aphids are agricultural pest insects that transmit viruses and cause feeding damage on a global scale. Current pest control practices involving the excessive use of synthetic insecticides over many years have resulted in aphid resistance to a number of pesticides. In nature, plants produce secondary metabolites during their interaction with insects and these metabolites can act as toxicants, antifeedants, anti-oviposition agents and deterrents towards the insects. In a previous study, we demonstrated that the butanol fraction from a crude methanolic extract of an important plant species, Isodon rugosus showed strong insecticidal activity against the pea aphid, Acyrthosiphon pisum . To further explore this finding, the current study aimed to exploit a bioactivity-guided strategy to isolate and identify the active compound in the butanol fraction of I . rugosus . As such, reversed-phase flash chromatography, acidic extraction and different spectroscopic techniques were used to isolate and identify the new compound, rosmarinic acid, as the bioactive compound in I . rugosus . Insecticidal potential of rosmarinic acid against A . pisum was evaluated using standard protocols and the data obtained was analyzed using qualitative and quantitative statistical approaches. Considering that a very low concentration of this compound (LC 90 = 5.4 ppm) causes significant mortality in A . pisum within 24 h, rosmarinic acid could be exploited as a potent insecticide against this important pest insect. Furthermore, I . rugosus is already used for medicinal purposes and rosmarinic acid is known to reduce genotoxic effects induced by chemicals, hence it is expected to be safer compared to the current conventional pesticides. While this study highlights the potential of I . rugosus as a possible biopesticide source against A . pisum , it also provides the basis for further exploration and development of formulations for effective field application.

“…Patil et al (2003) reported the mean egg laying by P. xylostella decreased from 56.7 to 32.66 on plant surface treated with A. calamus (aqueous extract) as the time increased from 0 to 3 days. Similarly, Basukriadi and Wilkins (2014) also reported the residual effect of yam been seed extract (1%) as egg laying decreased from 1 to 3 days from 77 to 59 of P. xylostella. Plant extracts having nonvolatile properties are more useful compounds for oviposition deterrent (Renwick, 1988).…”

Medicinal plants of Himalayan region is inadequately known for their role in pest management. The present study was conducted to assess the response of different extracts of Acorus calamus (L.) and Vitex negundo (L.) on antifeedant and ovipositional deterrent activity of Plutella xylostella. Acorus calamus (Rhizome) and Vitex negundo (leaves) were taken as an experimental material. Methanol (polar solvent) and hexane (non-polar solvent) were used for extraction. Antifeedant and ovipostional deterrent effect of two plants were workout against Plutella xylostella. The data were statistically analysed by t-tests for paired comparisons. Stronger ovipositional deterrent effects was observed in A. calamus (methanol extract) with higher oviposition deterrent indices (ODI) (38.7), followed by hexane extract of V. negundo. The leaves treated with plant extracts of A. calamus and V. negundo deterred the female of P. xylostella to some extent to lays eggs. After three days of treatment, methanol extract of A. calamus showed a residual deterrent effect to female of P. xylostella due to its low volatile nature. Application of methanol and hexane extracts of A. calamus and V. negundo on host plants render them less attractive and show ovipositional deterrent to females of P. xylostella.

“…The advantage of this is its selective action against parasites and pest predators, as well as pollinators. Plant antifeedant substances prepared from secondary metabolites are found in all groups; however, the most effective insect feeding inhibitors come from terpenoids, alkaloids, saponins, and polyphenols (Koul, 2005) and oviposition reducers come from cumarina and rutina (Tabashnik, 1985) andrographolide (Hermawan et al, 1998) and a-terpineno, Limonene, linalool (Zhang et al, 2004), essential oils (Dover, 1985;Zhang et al, 2004) and plant extracts (Abbasipour et al, 2010;Basukriadi & Wilkins, 2014;Chen et al, 1996;Egigu et al, 2010;Kodjo et al, 2011;Patil et al, 2003). These substances also inhibit the oviposition of P. xylostella.…”

The indiscriminate use of synthetic insecticides caused an increase in the resistance of Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae) to almost all classes of insecticides, as well as affected the environment and non-target organisms. Thus, the search for less harmful alternatives with the purpose of reducing the application of these insecticides has become a priority. A possible alternative to reduce the use of synthetic insecticides is by using botanical insecticides, given the thousands of existing compounds derived from secondary metabolism in plants. In this study, we tested the following hypotheses: (i) the aqueous and ethanolic extracts of native plants reduce the food consumption of larvae and oviposition of adults of P. xylostella; (ii) these botanical species can act as potential plant insecticides. The objective of this work was to evaluate the effect of plant extracts on the feeding preference of larvae and oviposition of adults of P. xylostella. For this, cabbage discs treated with aqueous and ethanolic extracts of Schinus terebinthifolius, Annona coriacea, Annona crassiflora and Serjania marginata were given to larvae. The concentrations used for the aqueous extracts were of 5 and 10 mg mL-1, and for the ethanolic extracts were of 1 and 5 mg mL-1. Both extracts of the four tested plant species showed oviposition suppressed. The extract of S. marginata showed the lowest rates of suppression. All treatments with ethanolic extracts showed a phagodeterrant effect being that the aqueous and ethanolic extracts of A. crassiflora and S. terebinthifolius were the most effective as antifeedants on third instar larvae by P. xylostella.
