“…In the same way, many chloroform extracts from plants have shown antifeedant activities against Lepidoptera species. For example, chloroform extracts of Atalantia monophylla (Baskar et al 2009), Caesalpinia bonduc (Baskar et al 2018), and Clerodendrum phlomidis (Duraipandiyan et al 2015;Muthu et al 2015) were antifeedant agents against Helicoverpa armigera (Lepidoptera: Noctuidae) at concentrations between 0.02 and 5%. Additionally, chloroform extract of Gloriosa superba elicited an antifeedant behavior from Spodoptera litura (Lepidoptera: Noctuidae) (Nebapure et al 2016) at 0.03% concentration.…”

Hylurgus ligniperda is one of the most important quarantine forest insects associated to pine (Pinus radiate D. Don) logs exported from Chile. Methyl bromide fumigation has been the prominent control method. As the use of this synthetic insecticide leads to serious environmental problems, research to find alternative treatments is urgently needed for the Chilean forestry sector. Hence, plant secondary metabolites have been considered as an alternative for its control. Therefore, the objective of this work was to assess the feeding behavior of H. ligniperda through the artificial diet supplemented with organic fractions obtained from Cestrum parqui leaves. Organic extracts were obtained using a Soxhlet extraction. Non-choice tests were developed for testing the antifeedant activity shown by the organic fractions on adults, and 5th and 6th instar larvae of H. ligniperda. All the extracts tested elicited a decrease in the weight of unsexed H. ligniperda adults, and the effects were dose-dependent. Male beetle weight gain was reduced strongly by chloroform extracts and ethyl acetate elicited a weight increase of female and from the fifth and sixth instar larvae weight. Saponin extract elicited a reduction of the weight in male and female. Finally, the weight of both instar larvae was reduced by chloroform and saponin extract. C. parqui leaf extracts show a great potential for being used for controlling H. ligniperda and thus to diminish the use of harmful synthetic pesticide.

“…It would be very beneficial to develop novel natural insecticides from some undiscovered plant species, such as insecticidals, ovicidals, antifeedants, and ovipositional deterrents, as an effective substitute for synthetic pesticides. The action of plant-derived compounds on pest insects is exerted in many ways, such as an as an antifeedant [1]; a larvicidal [9]; an ovicidal [10]; oviposition deterrent activity [10]; and a repellent [11].…”

Different organic solvent extracts of Cymodocea serrulata leaves exhibited antifeedant activity against Spodoptera litura larvae. Maximum antifeedant activity (88.95%) was observed in ethyl acetate extract at a 5 percent concentration. Five fractions were isolated from ethyl acetate extract by column chromatography and tested individually at four different concentrations, viz., 125, 250, 500, and 1000 ppm, for antifeedant activity. Among the five fractions, fraction I showed promising antifeedant activity (91.12%) at a 1000 ppm concentration. Deformities in larvae, pupae, and adults were also recorded. The preliminary phytochemical analysis showed the presence of alkaloids, terpenoids, flavonoids, tannins, phenolic compounds, glycosides, and steroids.

“…Hence, we need to identify effective alternatives for control. Biopesticides derived from medicinal plants and microorganisms possess several advantages over chemical pesticides, such as biodegradability, lack of resistance from pests, and sustainability. − Meanwhile, although these pesticides also have the following disadvantages, such as high structural complexity, limited compound availability, and poor drug-likeness, botanical and microbial metabolites are potential candidates for the development of new pesticides.…”

Endophytic fungi have proven to be prolific producers of bioactive secondary metabolites with agricultural applications. In this study, bioassay-guided isolation of the endophytic fungus Acremonium vitellinum yielded four anthraquinone derivatives (compounds 1−4), including a previously undescribed dimethylated derivative of bipolarin, 6,8-di-O-methylbipolarin (1). Their structures were determined by 1D and 2D nuclear magnetic resonance analysis as well as high-resolution electrospray ionization mass spectrometry data, and the absolute configuration of 1 was established by comparing the calculated and experimental electronic circular dichroism spectra. The insecticidal activity of the isolated compounds against the cotton bollworm Helicoverpa armigera was evaluated. The new compound 1 showed the strongest larvicidal activity against the 3rd instar larvae of H. armigera with an LC 50 value of 0.72 mg/mL. In addition, transcriptome sequencing was performed to evaluate the molecular mechanism of the insecticidal activity. In total, 5732 differentially expressed genes were found, among which 2904 downregulated genes and 2828 upregulated genes were mainly involved in cell autophagy, apoptosis, and DNA mismatch repair and replication. The results presented in this study reveal how 1 exerts its insecticidal effects against H. armigera via genome-wide differential gene expression analyses. Our findings suggest that anthraquinone derivatives are potential biopesticides for cotton bollworm control.
