“…(2021) synthesized the silver nanoparticles with aqueous seed extract of A. squamosa exhibited larvicidal effect against third instar mosquito larvae with an LC 50 value of 22.44 g/mL. The methanol extract of A. squamosa seeds was more toxic to cabbage caterpillar, Crocidolomia pavonana larvae, with LC 50 and LC 95 values of 0.04 % and 0.16 %, respectively (Nenotek et al,2022). Histological changes have been reported to occur in larval midgut following the consumption of toxic compounds by the insects, severely affecting the insect physiology (Sreeletha and Geetha, 2012;Farder et al, 2022).…”

The tobacco caterpillar, Spodoptera litura F., is one of the most devastating, cosmopolitan polyphagous pests affecting major crops that significantly impact agricultural productivity. The present study aimed to evaluate the toxicological effect of seed extract of the medicinal plant, Annona squamosa L. and the histological effect on the midgut of Spodoptera litura F., under laboratory conditions. The crude methanolic extract of A. squamosa seed was tested against the third instar larvae of S. litura at five different concentrations viz., 0.5%, 1.0%, 1.5%, 2.0% and 2.5 % by leaf dip bioassay method. The seed extract exhibited larval mortality of 96.67%, 83.37 %,70%, 53.33% and 40 % at the concentrations 2.5 %, 2.0%, 1.5%, 1.0% and 0.5%, respectively.The results indicated that the response of larval mortality to the seed extract was dose-dependent. The dose of 0.5% showed the lowest mortality (40.00%), while the dose of 2.5 % showed maximum larval mortality (96.67%). Hence they were subjected to histological analysis. The anatomical sectioning of S. litura larval midgut treated with 0.5% concentration showed disruption in the peritrophic membrane and striated border of epithelial cells. The midgut of larvae treated with 2.5 % concentration showed an irregular epithelium and high vacuolization in the cytoplasmic cells. The results indicated that methanol extract of A. squamosa seed extract has the ability to cause changes in the midgut region, thereby affecting the digestion and nutrient absorption of S. litura larvae, which will lead to a debilitating effect on the development of larvae. Based on the present study A. squamosa seed extract will be a potential biopesticide for managing S. litura.

“…The mixture of T. vogelii seed extract and Quassia amara leaf extract had insecticidal properties against C. pavonana larvae, which was stronger than separately extract treatment (Nenotek 2010). In a previous study, separate testing of A. squamosa and T. vogelii seeds effectively killed the larval instar III H. armigera, with LC 50 values of 0.89 and 0.15 (Nenotek and Ludji 2016). Information about the synergy of a mixture of A. squamosa and T. vogelii seed extracts has not been reported.…”

Abstract. Nenotek PS, Ludji R. 2020. The efficacy of seed extract of Tephrosia vogelii and Annona squmosa on larvae of Helicoverpa armigera. Trop Drylands 4: 5-9. Corncob borer (Helicoverpa armigera) is important pest of corn, urging the use of insecticide for its eradication. While using chemical insecticides is not sustainable, the use of plant-based insecticides is thus recommended. This study aimed to determine the efficacy of Annona squamosa and Tephrosia vogelii seed extract mixture on the mortality of 3rd instar larvae of Helicoverpa armigera. A range of concentration, as treatments, were evaluated, i.e., 0.05%, 0.11%, 0.28%, 0.65%, 1.5% and a control (water only) applied with three replicates in each treatment. Ten larvae of H. armigera at each treatment were infested in baby corn, using the residue method. Mortality was observed at 24, 48, 72, 96, and 120 hours after treatment (HAT). Percent mortality of the 3rd instar of H. armigera larvae was analyzed using Probit Polo PC, then proceed with mixed activity analysis. The results showed that the mixture of A.squamosa + T. vogelii seeds extracts killed H. amigera larvae with the value of LC50 and LC95 of 0.07% and 2.07%, respectively. A mixture of A. squamosa seeds + T. vogelii seeds extract was synergistic to H. armigera larvae with combined index values at LC50 and LC95 were 0.53 and 0.58, respectively. Thus, the use of a mixture of A. squamosa seed extract and T. vogelii seed is more efficient because the raw materials used were less at low concentrations to control H. armigera larvae than the extract applied separately.
