“…According to our data, the toxicity of AcF and EtF at different concentrations (60, 50, 40, 30, and 20 mg/L) AcF, and (100, 50, 40, 30, and 20 mg/L) for EtF for 24, 48, and 72 h, reflected that the lowest LC 50 value (39 mg/L) was for AcF after 72 h, and 42 mg/L for EtF. These results showed that the AcF extract is more potent than EtF extract, which is in an agreement with Abdelkhalek et al [ 13 ], who found that the acetone fraction of water hyacinth was the most effective against Agrotis ipsilon . Similarly, Jayanthi et al [ 20 ] found that water hyacinth extracts have insecticidal activity against Culex quinquefasciatus and the mortality increased by increasing the concentrations.…”

“…Thereafter, an electrical blender was used for grinding the dried plants. The preparation and modifications of fractionated extracts (acetone and ethanol fractions) were prepared according to our previously published work [ 13 ]. LC 50 concentrations of AcF and EtF (240 and 370 mg/L, respectively) extracts were used in this study.…”

“…LC 50 concentrations of AcF and EtF (240 and 370 mg/L, respectively) extracts were used in this study. The LC 50 concentrations used in the current research were determined according to the previous bioassay test for Agrotis ipsilon [ 13 ]. Since it is stronger than Aphis craccivora , we used their LC 50 to be more accurate in the safety assessment tests.…”

“…They can act by disrupting some physiological and biological processes in the pest [ 11 ]. Botanical products service to be insect growth regulators, insecticides, repellents, and antifeedants for a large scale of insect pests due to their attribution to some active secondary metabolites, such as alkaloids, flavonoids, and terpenoids [ 12 , 13 ]. The extraction of such toxic bioactive phytochemicals opens the vista for further assessment as insecticidal agents, as these phytochemical compounds are considered a large reservoir of different chemical structures with a variety of biological activities [ 14 ].…”

“…The root extract had 100% mortality when subjected to Chironomus ramosus larvae [ 19 ]. Moreover, acetone and ethanol fractions had a promising toxic effect on Agrotis ipsilon larvae [ 13 ]. Hexane and methanolic extracts had an insecticidal activity on all Culex quinquefaciatus stages [ 20 ].…”

Eichhornia crassipes were evaluated in order to investigate the insecticidal activity towards Aphis craccivora adults. The LC50 values were promising and reflected the bio-efficacy of the tested extracts (39 and 42 mg/L), respectively, and reduced the fecundity markedly. Using GC/MS analysis, the major components were n-hexadecanoic, linolenic, hexadecenoic, myristic, stearic acids, linolelaidic acid, methyl ester and some terpenoids, alkaloids, and hydrocarbons. A safety assessment of non-target organisms is essential for the development of new pesticides. In order to guide the rational use of the most potential insecticidal extracts AcF and EtF, the effect of these extracts on body weight, hematological indices, biochemical indicators, and histopathology of some relevant organs of albino rats (as a model for mammals) was investigated. The research outcomes revealed that the LC50 of AcF and EtF extracts had gradually raised body weight for 14 days (p > 0.05). Similarly, there were no remarkable alternations in the complete blood count (CBC); only a slight decrease in the monocytes count (612 ± 159.80 × 103 µL) in the EtF-treated group. There was a notable increase in alanine transferase (ALT) activity (36.73 ± 1.44 IU/L) in the AcF-treated group. No destructive changes were noted with the remaining biochemical parameters. Cholesterol and triglycerides non-significantly increased in the EtF group, whereas, cholesterol levels decreased significantly in the AcF group. In addition, histopathological examination reflected minor changes in AcF and EtF groups in the form of mild inflammation in the lungs and mild vacuolar degeneration in the kidneys, while no lesions were detected in the heart and liver in the same groups. Thus, the present research suggested that AcF and EtF extracts of E. crassipes are safe green insecticides for insect control strategies.

Endosymbionts are known to have significant effects on their insect hosts, including nutrition, reproduction, and immunity. Insects gut microbiota is a critical component that affects their physiological and behavioral characteristics. The black cutworm (BCW), Agrotis ipsilon, is an economically important lepidopteran pest that has a diverse gut microbiome composed of nine species belonging to three phyla: Proteobacteria, Actinobacteria, and Firmicutes. This study was conducted to investigate the diversity of gut bacteria isolated from BCW larvae and moths and their effects on metabolism and pesticide degradation. The bacterial isolates were identified using the 16 S rRNA gene. The study showed that the gut microbiome composition significantly affected the metabolism of BCW larvae. Based on the screening results of synthesis of digestive enzymes and pesticide degradation, Brachybacterium conglomeratum and Glutamicibacter sp were selected to perform the remaining experiments as single isolates and consortium. The consortium-fed larvae showed high metabolic indices compared to antibiotic-fed larvae and the control. The gut bacteria were also shown to degrade three pesticide groups. Concerns regarding the health risk of chlorpyrifos have been raised due to its extensive use in agriculture. The isolated B. conglomeratum was more effective in chlorpyrifos degradation than the consortium. Furthermore, the study also examined the presence of sex related endosymbionts (Wolbachia, Spiroplasma, and Rickettsia) in the reproductive tissues of adults. The outcomes demonstrated that none of the examined endosymbionts existed. In conclusion, the study highlights the importance of the gut microbiome in insect physiology and behavior and its potential applications in biotechnology. It provides insights into developing eco-friendly pest control and bioremediation strategies using gut bacteria.
