Abstract The aphid Myzus persicae Sulzer (Hemiptera: Aphididae) causes significant crop damage by feeding on plant tissues, transmitting viruses, and reducing agricultural productivity. Challenges associated with chemical control methods, such as the development of pest resistance adverse environmental impacts, highlight need to enhance efficacy natural enemies for sustainable management. Methyl salicylate (MeSA) has been extensively studied in management using baited traps slow-release...
This article presents new similarity solutions for heat and mass transfer in flow of Carreau fluid over a rough (non-flat) sheet with variable kinematics. While the dynamics have been extensively studied, previous work has serious issues treatment dimensionless parameters, particular Weissenberg number. Principally, investigations fluid, governing equations, when transformed into system ODEs, contained space-dependent number, which is contrast to soul solutions, certainly, such very narrow...

Current model includes all previous cases of stretched/shrunk flows with thermal effects discussed so far. Moreover, we present three different behavior (i) prescribed surface temperature (ii) Variable/uniform convective at plat (iii) variable/uniform flux. Stretching/shrinking velocity U w (x), porosity...

Nano-fluid flow is maintained over a non-uniform porous plate of variable thickness with stretching (shrinking) velocity. In real engineering systems, the conduction resistance sheets necessarily important, whereas, in typical analysis very thin walls are undertaken. The surface ignored classical studies flow, heat, and mass transfer problems. However, it compulsory component many physical problems, therefore, we thoroughly examined perceptiveness wall on field variables transport heat...

Initially, symmetrical solutions the boundary value found for upper half channel. Later on, these extended to lower then whole compared exactly matched each other small parameters involved problem. It is also confirmed...
