“…Insect antifeedants are used as crop protectants, triterpenoids being a well‐known example . Plant extracts or phytochemicals are potentially useful as commercial insect control agents or as lead compounds . Plant‐derived pesticides (botanicals) can interfere with egg hatchability, oviposition, growth and feeding, and can kill Insects .…”

BACKGROUND: The triterpenoid friedelin isolated from hexane extract of Azima tetracantha leaves was evaluated for its antifeedant, larvicidal and pupicidal activities against Helicoverpa armigera and Spodoptera litura at 125, 250, 500 and 1000 ppm concentration. RESULTS: Friedelin exhibited antifeedant (84.57 and 75.28%), larvicidal (72.88 and 66%) and pupicidal (76.18 and 66.66%) activities against H. armigera and S. litura respectively. The homogeneity of variances (Levene statistic) showed significant deviation for the antifeedant, larvicidal and pupicidal activities of friedelin against H. armigera and S. litura. It exhibited LC 50 values of 130.47 and 226.41 ppm for antifeedant and 509.56 and 607.99 ppm for larvicidal activities against H. armigera and S. litura respectively. In linear regression analysis, significant and high correlation was noted between concentration and antifeedant activity with R 2 = 0.84 and 0.79 and between concentration and larvicidal activity with R 2 = 0.81 and 0.76 against H. armigera and S. litura respectively.CONCLUSION: Regression between antifeedant and larvicidal activities also showed significant activity (P = 0.00) with R 2 = 0.79 for H. armigera and R 2 = 0.70 for S. litura. Friedelin showed good activity against both the pests. Friedelin did not show any toxicity against freshwater fish Cyprinus carpio at 100 mg L −1 . Friedelin could be used to prepare a botanical formulation to control the agricultural pests. a Values represent the mean ± SD of five replicates (n = 50). Similar letters in a column indicate that the values do not differ significantly according to Tukey's HST test (P ≤ 0.05). R* is the relationship between concentration and antifeedant activity.

“…Rotenone, another important botanical insecticide extracted from various plants, including species of Derri s, Millettia, Tephrosia and Lonchocarpus , has been shown to be an effective control agent of many pest species, including aphids, mites and moths [ 20 , 21 , 22 , 23 ]. In China, there are 19 rotenone-based insecticides licensed to control aphids, the diamondback moth and other important pests of vegetables [ 24 ].…”

The joint action of destruxins and three botanical insecticides, rotenone (Rot), azadirachtin (Aza) and paeonolum (Pae) against the cotton aphid, Aphis gossypii, was bioassayed. In laboratory experiment, several synergistic groups of destruxins with botanical insecticides were found by means of Sun’s Co-toxicity Coefficients (CTC) and Finney’s Synergistic Coefficient (SC). The best synergistic effect was discovered in the ratio group Des/Rot 1/9 with the CTC or SC and LC50 values of 479.93 or 4.8 and 0.06 μg/mL, respectively. The second and third synergistic effects were recorded in the ratio groups Des/Rot 7/3 and 9/1. Although the ratio groups Des/Aza 6/4, Des/Pae 4/6, 3/7 and 2/8 indicated synergism by Sun’s CTC, they were determined as additive actions by Finney’s SC. Additive actions were also found in most of the ratio groups, but antagonism were recorded only in three ratio groups: Des/Pae 9/1, 7/3 and 6/4. In greenhouse tests, the highest mortality was 98.9% with the treatment Des/Rot 1/9 at 0.60 μg/mL, meanwhile, the treatments Des/Pae 4/6 and Des/Aza 6/4 had approximately 88% mortality.

Antifeedant effect of commercial chemicals and plant extracts againstSchistocerca americana(Orthoptera: Acrididae) andDiaprepes abbreviatus(Coleoptera: Curculionidae)

Abstract: Based on their deterrency, some of the commercial products and plant extracts have potential for use as substitute crop protectants against the pest species tested.
