Preparation and Application of Volatilized Wormwood Essence Derived Naturally into Green Insecticide

Molecules, Journal Year: 2024, Volume and Issue: 29(12), P. 2877 - 2877

Published: June 17, 2024

Naturally occurring substances and their derivatives function as vital resources for pesticides that can be used in fields, such insecticide production fungicide development. As a botanical entity displaying multifaceted biological functions, wormwood has received thorough scrutiny across multiple sectors. The insect repellency potency combined with antibacterial antifungal activities of position it potential candidate prospective development into eco-friendly chemical pesticides. In this research, Wormwood essential oil was procured via ethanol water under ultrasonic scenarios subsequently diluted PEG 400 to formulate green defensive efficacy pesticide on plants validated through 2 weeks clustered plant growth experiments. Active constituents exerted effects were scrutinized by GC-MS. Furthermore, also displays efficacious the prevention management aphids, exhibiting dose-dependent relationship. 4-terpenol, eucalyptol, carvacrol, L-borneol identified GC-MS predominant active pesticide. leveraged develop pesticides, which protect without contaminating environment.

Upregulation of Insulin and Ecdysone Signaling in Relation to Diapause Termination in Bombyx mori Eggs Exposed to 5 °C

Insects, Journal Year: 2024, Volume and Issue: 15(12), P. 989 - 989

Published: Dec. 12, 2024

In the present study, we investigated possible correlation between insulin/ecdysone signaling and chilling-induced egg diapause termination in Bombyx mori. Changes insulin (bombyxin-Z1) ecdysteroid-phosphate phosphatase (EPPase) gene expression levels chilled eggs (whose had been terminated by chilling to 5 °C for 90 days) exhibited no significant increase after being transferred 25 °C, which differed from both non-diapause HCl-treated eggs. We further compared differential temporal expressions of (bombyxin-A6, -Y1, -Z1), ecdysone (EPPase E75A), metabolic-related (trehalose transporter 1 (Tret1) trehalase (Treh1)) as well sorbitol dehydrogenase 2 (SDH2) genes kept at °C. Our results showed that all remained very low However, eggs, changes were detected according different genes, with bombyxin-A6 EPPase maintained relatively constant, high levels. Higher E75A, Tret1, Treh1 also Expressions SDH2 bombyxin-Z1 decreased during first 15 days then increased 30 chilling. Ecdysteroid phosphorylation glycogen synthase kinase (GSK)-3β, a downstream target signaling, higher These suggested due glucose metabolism was sustained, leading continued depletion metabolic reserves. On day chilling, means adjust nutrient requirements maintain embryonic homeostasis, began increase, followed gene. Along level eventually terminate B. mori To our knowledge, this is study demonstrate termination.
