A field strain of Spodoptera littoralis Biosduval was selected against Cry1C toxin derived from Bacillus thuringiensis entomocidus for 10 subsequent generations under laboratory conditions. Selection pressure resulted in a 29‐fold resistance ratio compared with the susceptible strain. Inheritance of Cry1C resistance was partially dominant and autosomal on the basis of bioassay response to Cry1C toxin in a reciprocal cross between male and/or female F1. Consistent with earlier findings, resistance was recessive at high concentrations of Cry1C toxin. However, the dominance of resistance increased as the concentration of Cry1C decreased. Analysis of survival and growth of progeny from a backcross (F1 × resistance strain) suggested that resistance was controlled by either a single or a few loci in cotton leafworm.

Background: Emergence agitation (EA) is a common problem after sevoflurane anesthesia among children. There have been mixed results with control of EA using propofol 1 mg/kg bolus following sevoflurane anesthesia. An infusion of 3 mg/kg of propofol over 3 min following sevoflurane anesthesia has been found to be promising in children undergoing magnetic resonance imaging scans. However, no studies have been conducted during surgical procedures. We aimed to examine the efficacy of transition to propofol for 3 min after cessation of sevoflurane anesthesia in children undergoing inguinal hernia repair. Methods: In this prospective randomized controlled trial, 64 children aged 1–12 years, scheduled for inguinal hernia repair, were randomized to receive either propofol 3 mg/kg over 3 min (propofol group) or no propofol (control group), after the cessation of sevoflurane anesthesia. EA was assessed using the Paediatric Emergence Anesthesia Delirium (PAED) scale and the Watcha scale. Emergence time and the duration of post-anesthesia care unit (PACU) stay were also recorded. Results: The incidence of ED was lower in the propofol group on both the PAED (81.3% vs. 15.6%, P < 0.001) and the Watcha (78.1% vs. 15.6%, P < 0.001) scales. The mean emergence time was 6.37 minutes longer in the propofol group with no significant difference in PACU times. Conclusions: Transition to propofol 3 mg/kg over 3 min following sevoflurane anesthesia reduces the incidence of EA and improves the quality of emergence. Although emergence times were longer, the duration of stay in the PACU was similar with propofol use.

The current investigation is concerned with the rheological impact of fourth-grade confined by Riga surface. The flow behaviour is analysed over a Riga plate in the presence of stagnation point and porous medium. The relevant similarity variables and corresponding boundary conditions are adopted to model the current problem. The highly non-linear coupled differential system is via optimal homotopy scheme. The outcomes of relevant dimensionless parameters on the velocity profile have been visualized with physical exploration. It is observed from the obtained outcomes that the fluid velocity declines against rising estimations of modified magnetic variable and inverse Darcy number. The increasing velocity change is noted for boosting values of third-grade fluid parameter. Moreover, the velocity pattern for fourth-grade material is comparatively higher than viscous, second-grade, and third-grade materials. The comparative analysis against obtained simulations is also listed.
