Permanence and Existence of Periodic Solutions for Nicholson’s Blowflies Model with Feedback Control and Delay on Time Scales

open access: yesDiscrete Dynamics in Nature and Society, 2018
Sufficient conditions are established for the permanence in a delayed Nicholson’s blowflies model with feedback control on time scales. Our investigation confirms that the bounded feedback terms do not have any influence on the permanence of this system.

A history of southern African research relevant to forensic entomology [PDF]

open access: yes, 2006
Entomological forensic evidence has been used in southern Africa for decades but explicitly forensic research began in southern Africa only 26 years ago.

Diversity of Calliphoridae and Sarcophagidae (Diptera: Oestroidea) in a forested area in the municipality of Macaé, RJ, Brazil

open access: yesEntomoBrasilis
Sarcophagidae and Calliphoridae are families of Diptera that cover, respectively, about 3,100 and 1,000 species described worldwide. The species of these families have medical and veterinary importance, due to their role as vectors of pathogenic agents.

New results on periodic solutions of delayed Nicholson's blowflies models

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
This paper is concerned with a class of Nicholson's blowflies models with a nonlinear density-dependent mortality term. We use coincidence degree theory and give several sufficient conditions which guarantee the existence of positive periodic solutions ...

Positive periodic solutions of delayed Nicholson's blowflies model with a linear harvesting term

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
This paper is concerned with a class of Nicholson's blowflies model with a linear harvesting term. By applying the method of coincidence degree, some criteria are established for the existence and uniqueness of positive periodic solutions of the model.

Delay effect in the Nicholson's blowflies model with a nonlinear density-dependent mortality term

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
This paper is concerned with a class of non-autonomous delayed Nicholson’s blowflies model with a nonlinear density-dependent mortality term. Under proper conditions, we prove that the positive equilibrium point is a global attractor of the addressed ...

Diffusion Model Applied to Postfeeding Larval Dispersal in Blowflies (Diptera: Calliphoridae)

open access: yesMemorias do Instituto Oswaldo Cruz, 1997
This paper presents a diffusion model of larval dispersal especifically designed to account for particular aspects of postfeeding larval dispersal from the food source in organisms such as blowflies. In these organisms the dispersal of immatures includes

Exponential Extinction of Nicholson's Blowflies System with Nonlinear Density-Dependent Mortality Terms

open access: yesAbstract and Applied Analysis, 2012
This paper presents a new generalized Nicholson’s blowflies system with patch structure and nonlinear density-dependent mortality terms. Under appropriate conditions, we establish some criteria to guarantee the exponential extinction of this system ...

Origins and Diversification of Myiasis Across Blowflies

open access: yesEcology and Evolution
Parasitism represents a prevalent and successful ecological strategy that has evolved independently numerous times across metazoa. Understanding the origin and diversification of parasitism is a central question in evolutionary biology.
