“…The present study supports the earlier work of Kangade and Zambare (2013) where 100% mortality of rice moth was observed in methanol extract of Argemone mexicana. Similar results were also obtained by Tavares et al (2014) that ethanol extract of T. diversifolia flower caused higher mortality and repellency of Sitophillus zeamais and Sitotroga cerealella (Fouad et al, 2014). The methanol extract of T. diversifolia leaves were toxic to C. maculatus (Green et al, 2017) and Anopheles gambiae (Ileke et al, 2019).…”

Post-harvest losses of agricultural produce due to storage food grain pests lead to detrimental effects on the economic growth of any nation. However, a solution to this is to rely on adapting necessary cultural operations and effective traditional remedies that are locally available, which are inexpensive for the control of pests. Tithonia diversifolia (Hemsl.) A. Gray is an invasive weed that grows along the roadside and wasteland in rural and urban areas. The objective of this study was to evaluate the pesticidal efficacy of powder and extracts of T. diversifolia flower by using different solvents such as aqueous, methanol, chloroform, hexane, petroleum ether and ethyl acetate against rice moth, Corcyra cephalonica. The dry powder and extracts of T. diversifolia flower were tested to check the mortality of C. cephalonica eggs, larvae, and adults under the laboratory conditions (28 ±2 °C and relative humidity 65 ±5%). The mortality of the insect increased with an increase in the concentration of extracts. The results showed that the different solvent extracts of T. diversifolia flower were significantly more effective than the dry powder and control against different developmental stages of C. cephalonica. Methanol and ethyl acetate extracts showed an almost equitoxic lethal effect on all three stages of the life cycle of C. cephalonica. The present work suggests that the T. diversifolia flower possesses insecticidal properties against C. cephalonica eggs, larvae and adults. Thus, it can be recommended for use by the farmers as a potential pesticidal plant.

“…The leaf extract from Senna obtusifolia (L.) H.S. Irwin & Barneby (Fabaceae) showed repellency activity of class II (between 20.1-40%) to control adults of Sitophilus zeamais (Motschulsky) (Coleoptera: Dryophthoridae) (de Souza Tavares et al 2014). For its part, the ethyl acetate extract of the seeds (EtOAc) and secondary metabolites of Senna tora (L.) Roxb.…”

“…Previous phytochemical studies have allowed the identification of a variety of compounds found in Senna spp., including alkaloids (Moo-Puc et al 2007), anthraquinones (Branco et al 2011), cardiac glycosides (Essiett & Bassey 2013), glucosides (sennosides) (Monkheang et al 2011), naphthopyrones (Graham et al 2004), phenols (Viegas Junior et al 2013, saponins (Oluwole et al 2016), triterpenes, (Luximon-Ramma et al 2002, among others. The metabolic content of Senna species has been associated with a variety of biological properties, including insecticidal activity (Yagi et al 2013;de Souza Tavares et al 2014;Vasudev et al 2015). Senna crotalarioides (Cassia crotalarioides Kunth [Fabaceae]) is an arborous species distributed in various states of Mexico (Estrada et al 2004).…”

Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae) (fall armyworm) is a pest native to the Americas that affects a variety of crops. Its control is based on chemical insecticides. However, this practice has been associated with changes in the susceptibility of pests to various insecticides. The use of plant products represents an eco-friendly alternative. The objective of this work was to evaluate the larvicidal activity of the chloroform extract of Senna crotalarioides (Kunth) H.S. Irwin & Barneby (Fabaceae) to control S. frugiperda. The chloroform extract of S. crotalarioides caused significant larval mortality, and reduced pupal weight and adult emergence. The analysis by gas chromatography coupled with mass spectrometry (GC-MS) revealed the presence of 22 compounds in the chloroform extract of S. crotalarioides leaves, with the straight-chain aliphatic fatty alcohol 1-octacosanol as the main component. This study revealed that the leaves of S. crotalarioides synthesize long chain alcohols, which increased the mortality of S. frugiperda in its larval stage, including the pupal stage. The extract also caused a decrease in the S. frugiperda pupal weight. The potential use of the chloroform extract obtained from S. crotalarioides and its principal chemical constituent is proposed as a promising alternative to control S. frugiperda. ResumenSpodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae) es una plaga nativa del continente Americano que afecta a muchos cultivos. Para su control, se emplean insecticidas químico sintéticos. Sin embargo, esta práctica se ha asociado con la generación de resistencia del insecto a estos productos. El uso de productos botánicos representa una alternativa eco amigable. El objetivo de este trabajo fue evaluar la actividad larvicida del extracto clorofórmico de Senna crotalarioides (Kunth) H.S. Irwin & Barneby (Fabaceae) para controlar S. frugiperda. El extracto ocasionó mortalidad significativa de la larva. También se observó reducción de peso pupal y de emergencia de adultos. El análisis mediante cromatografía de gases acoplada a espectrometría de masas (GC-MS) reveló la presencia de 22 compuestos en el extracto clorofórmico de las hojas de S. crotalarioides, siendo el alcohol alifático de cadena lineal 1-octacosanol el componente mayoritario. Este estudio reveló que las hojas de S. crotalarioides sintetizan alcoholes de cadenas largas, los cuales ocasionan un incremento en la mortalidad en el estado larval e incluso en el estado pupal de S. frugiperda. También el extracto indujo la disminución del peso pupal. El uso potencial del extracto clorofórmico obtenido de S. crotalarioides así como de su compuesto mayoritario para controlar S. frugiperda se plantea como alternativas promisorias.
