“…The reason for this speculation is that the growth of insects has been found to be affected by some substances which were composed of secondary metabolites could be released from plants infested by pests 9 . For example, the pupal weight and adult emergence of S. frugiperda could be significantly affected by the chloroform extract of S. crotalarioides 38 . Therefore, evaluating the relation between plant secondary substances and the growth and development of S. frugiperda would be a meaningful topic for future research, which is beneficial to develop phytochemical defense strategy and its application in agriculture.…”

BACKGROUND: The fall armyworm, Spodoptera frugiperda is one of the most destructive agricultural pests, which can complete their entire life cycle on various plants. At present, some detoxification genes have been proved to be involved in the adaptability to plants in insects. However, the genetics behind insect pest responses to host switches, and their ability to adapt to new host plants, remain poorly understood. This study was conducted to evaluate the adaptation of S. frugiperda to host plant and determine the roles of CYP321A9 and CYP9A58 in the detoxification metabolism of the fall armyworm.RESULTS: The results revealed that feeding on maize was more suitable for S. frugiperda to develop compared with rice. In addition, knocking down of SfCYP321A9 and SfCYP9A58 resulted in a prolonged developmental time of S. frugiperda larvae that fed on rice. Meanwhile, RNAi knockdown of SfCYP321A9 resulted in significantly higher mortality of S. frugiperda larvae when exposed to the rice allelochemicals, ferulic acid, gramine and tricin. Furthermore, overexpression of SfCYP321A9 significantly reduced mortality in Drosophila melanogaster when exposed to gramine and tricin. CONCLUSION: Our results suggest that CYP321A9 and CYP9A58 genes play a key role in host plant adaptation in S. frugiperda, which contribute to a greater understanding of the molecular basis of host plant adaptation and provide the means to develop effective management tools for S. frugiperda resistance.

“…Dried and powdered aerial parts (200 g leaves and stems) from S. connivens were extracted with 1 L of technical grade chloroform (Meyer, Tlahuac, México City, México) under reflux for 4 h. The extract was filtered, and the solvent was removed under reduced pressure using an RV10 basic rotatory evaporator (IKA, Wilmington, NC, USA). The yield of the extract was 5.13% [18].…”

Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) is one of the most damaging pests in maize crops. In order to manage it, synthetic insecticides such as diamides, neonicotinoids, and pyrethroids are used, but they present a risk for humans and the environment. Investigations of safer alternatives include the use of natural extracts. Thus, this research evaluated the effects of chloroform extract (CHCl3Sc) (5000, 4000, 2000, 1000, and 500 ppm) on aerial parts of Salvia connivens and of nonanal and pyrocatechol (1000, 600, 400, and 80 ppm) on S. frugiperda mortality, duration of the larva and pupae phases, and pupae weight after 24 h. The second instars of S. frugiperda larvae were fed an artificial diet incorporating the extract and compounds. The CHCl3Sc had insecticidal activity against S. frugiperda, showing an LC50 of 1504 ppm. Insectistatic activity began at 1000 ppm, increasing pupal and larval duration in 7.6 and 1.4 days, respectively. Pyrocatechol and nonanal were found in this extract. The first did not have any significant difference in larval or pupal mortalities. On the other hand, insectistatic activity was shown at 500 ppm, increasing the larval duration by 1.7 days compared with the control. In the case of nonanal, the insecticide activity was LC50 of 200 ppm, and insectistatic activity started at 80 ppm, increasing larval duration by 3.2 days compared with the control and reducing pupal weight by 3.4%. The results show that chloroformic extract had insecticidal and insectistatic activities against S. frugiperda; nonanal was an aldehyde compound present in this extract, which confers insecticidal and insectistatic activities against this pest.

Background Dianthus must be well investigated for its phytochemical content and biological and medicinal activities, including Dianthus orientalis Adams. Objectives To assess the phytochemical composition and determine the toxicity of Dianthus orientalis Adams in an animal model. Materials and Methods The whole plant materials were collected from July to August 2021 from Penjween district, Sulaimaniyah, Kurdistan of Iraq and then identified, authenticated, shadow-dried, and extracted using ethyl acetate and pure methanol to collect the crude extract of leaves and flowers separately. The GC-MS was run to determine the chemical composition and phytochemical content. Subsequently, the methanolic extract of the leaves was selected to be tested further for its toxicity in the male Sprague Dawley rat model using various techniques. Results The GC-MS results of the methanolic extract of Dianthus orientalis Adam’s leaves and flowers present the higher phytocomponents (no.=34). Some medicinal compounds have been identified in leaves and flowers with various concentrations. The animal toxicity study revealed body weight gain, no clinical signs of toxicity, and no mortality, with non-significant changes in treated animals' haematological, biochemical and histopathological profiles. Conclusions Various huge compounds have been identified in the studied plant parts corresponding to their safe use in an animal model.
