Mathematical modeling and control of population systems: Applications in biological pest control
(Elsevier B.V., 2008-07-01)
The aim of this paper is to apply methods from optimal control theory, and from the theory of dynamic systems to the mathematical modeling of biological pest control. The linear feedback control problem for nonlinear systems ...
Efficacy of chemical and biological strategies for controlling the soybean brown spot (Septoria glycines)
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2008)
Interactions of Bacillus thuringiensis bioinsecticides and the predatory stink bug Podisus nigrispinus to control Plutella xylostella
The diamondback moth (DBM), Plutella xylostella (L.), is a major pest of brassica crops worldwide. Control of this pest is difficult because it rapidly develops resistance to synthetic and biological insecticides and because ...
ASSESSING THE SUITABILITY of STERILE INSECT TECHNIQUE APPLIED TO AEDES AEGYPTI
(World Scientific Publ Co Pte Ltd, 2008-12-01)
The efficacy of biological control of Aedes aegypti mosquitoes using Sterile Insect Technique (SIT) is analyzed. This approach has shown to be very efficient on agricultural plagues and has become an alternative control ...
Classical biological control of an invasive forest pest: A world perspective of the management of Sirex noctilio using the parasitoid Ibalia leucospoides (Hymenoptera: Ibaliidae)
(Cambridge University Press, 2015-02)
Classical biological control is a key method for managing populations of pests in long-lived crops such as plantation forestry. The execution of biological control programmes in general, as the evaluation of potential ...
Computer simulation applied to the biological control of the insect aphis gossypii for the parasitoid Lysiphlebus testaceipes.
(In.: ECOLOGICAL MODELLING, v. 220, p.756-763, 2009., 2011)
Will the Convention on Biological Diversity put an end to biological control?
(Sociedade Brasileira De Entomologia, 2011)
Will the Convention on Biological Diversity put an end to biological control? Under the Convention on Biological Diversity countries have sovereign rights over their genetic resources. Agreements governing the access to ...
Periodontal and Prosthetic Biologic Considerations to Restore Biological Width in Posterior Teeth
(Lippincott Williams & Wilkins, 2011-09-01)
\ The biologic width is an essential dental space that always needs to be maintained to ensure periodontal health in any dental prosthetic restorations. An iatrogenic partial fixed prosthesis constructed in lower posterior ...
A NOTE ON SDRE CONTROL APPLIED IN PREDATOR-PREY MODEL: BIOLOGICAL CONTROL OF SPIDER MITE PANONYCHUS ULMI
(World Scientific Publ Co Pte Ltd, 2016-06-01)
The spider mite Panonychus ulmi (P. ulmi) is one of the most important pests of apple plantations. Studies suggested that spider mite Neoseiulus californicus (N. californicus) is able to control spider mite P. Ulmi, ...
Effect of Low-Temperature Storage on Diaeretiella rapae (McIntosh) (Hymenoptera: Braconidae)
We evaluated the effects of constant low-temperature storage on Diaeretiella rapae (McIntosh) (Braconidae, Aphidiinae). Diaeretiella rapae mummies were stored at 5 ± 1°C for 0-36 days. The percentage of D. rapae emergence ...
