Laboratory studies of the degradation of chlorpyrifos pesticide in soils supplemented by the fungus phanerochaete chrysosporium

Revista Facultad de Ingeniería Universidad de Antioquia, 2005
Degradation of the insecticide chlorpyrifos was investigated in sterilized soil samples supplemented by the white rot basidiomycete Phanerochaete chrysosporium. Degradation rates were measured during 21-day incubation at pesticide concentrations of 0,95,

A Mathematical Model of Flavescence Dorée Epidemiology [PDF]

arXiv, 2014
Flavescence dor\'ee (FD) is a disease of grapevine transmitted by an insect vector, $Scaphoideus$ $titanus$ Ball. At present, no prophylaxis exists, so mandatory control procedures (e.g. removal of infected plants, and insecticidal sprays to avoid transmission) are in place in Italy and other European countries.

New Terpenoids from Viguiera dentata: In Silico Pesticide‐Likeness Properties, Acetylcholinesterase Inhibition, Molecular Docking, and Evaluation against Spodoptera frugiperda

Chemistry &Biodiversity, EarlyView.
The chemical analysis of aerial parts of the melliferous Viguiera dentata led to the isolation of 20 substances, including the new cycloartanes 24‐epi‐argentatin C, 7β‐hydroxy‐24‐epi‐argentatin C, 7β‐hydroxy‐argentatin B. In‐combo results indicated that specific argentatins and ent‐kaurenoic acids have the potential to control Spodoptera frugiperda ...

High‐throughput behavioral phenotyping of tiny arthropods: Chemosensory traits in a mesostigmatic hematophagous mite

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 1, Page 46-62, January 1, 2023., 2023
We validated a new high‐throughput system based on nanocomputers connected to cameras automatically tracking movements of single mites. Our results confirm the existence of a volatile pheromone deposited by D. gallinae and attractive to conspecifics.

A fast-slow model for adaptive resistance evolution [PDF]

arXiv, 2019
Resistance to insecticide is considered nowadays one of the major threats to insect control, as its occurrence reduces drastically the efficiency of chemical control campaigns, and may also perturb the application of other control methods, like biological and genetic control.

Lienhwalides: Unique Tropolone–Maleidride Hybrids from Hypoxylon lienhwacheense

ChemBioChem, EarlyView.
Lienhwalides are novel tropolone–maleidride hybrid molecules unique in nature. Absolute configuration is solved by semisynthetic approaches and X‐ray analysis. Interplay between both lwt and lwm biosynthetic gene clusters is responsible for the production of lienhwalides.

A thermostable bacterial metallohydrolase that degrades organophosphate plasticizers

ChemBioChem, Accepted Article.
A cyclase‐phosphotriesterase (C‐PTE) from Ruegeria pomeroyi DSS‐3 has recently been identified for its capacity to detoxify several organophosphate compounds. However, several aspects of this enzyme remain unexplored, such as its activity with industrial organophosphates, its molecular structure and its thermostability.

Modeling and Optimal Control Applied to a Vector Borne Disease [PDF]

Proc. 12th Int. Conf. Comp. Math. Meth. Sci. Eng. (CMMSE'2012), Murcia 02-05 July 2012 (Ed: J. Vigo-Aguiar), Vol. III (2012), 1063--1070, 2012
A model with six mutually-exclusive compartments related to Dengue disease is presented. In this model there are three vector control tools: insecticides (larvicide and adulticide) and mechanical control. The problem is studied using an Optimal Control (OC) approach. The human data for the model is based on the Cape Verde Dengue outbreak.
