Effect Of Orius insidiosus (Hemiptera: Anthocoridae) And Spinosad (Conserve®) On Western Flower Thrips, Frankliniella occidentalis (Thysanoptera: Thripidae), Populations In Transvaal Daisy Flowers [PDF]

open access: yes, 2018
Western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), is a major insect pest of greenhouse-grown horticultural crops. Greenhouse producers typically apply insecticides to suppress WFT populations.

Analysis and optimal control of a malaria mathematical model under resistance and population movement [PDF]

open access: yesarXiv, 2020
In this work, two mathematical models for malaria under resistance are presented. More precisely, the first model shows the interaction between humans and mosquitoes inside a patch under infection of malaria when the human population is resistant to antimalarial drug and mosquitoes population is resistant to insecticides.

Implications of bio-efficacy and persistence of insecticides when indoor residual spraying and longlasting insecticide nets are combined for malaria prevention. [PDF]

open access: yes, 2012
Bio-efficacy and residual activity of insecticides used for indoor residual spraying (IRS) and long-lasting insecticide nets (LLINs) were assessed against laboratory-reared and wild populations of the malaria vector, Anopheles arabiensis in south eastern

Organic Insecticides [PDF]

open access: yesAnaesthesia and Intensive Care, 2000
Organic insecticide poisoning continues to be a major health problem not only in the developing communities but also in the Western population. The insecticides commonly used are the organophosphates, organocarbamates, organochlorides and pyrethroids.

Engineering of Transmembrane Alkane Monooxygenases to Improve a Key Reaction Step in the Synthesis of Polymer Precursor Tulipalin A

open access: yesAngewandte Chemie International Edition, EarlyView.
A biosynthesis route for the polymer precursor tulipalin A starting from isoprenyl acetate is proposed. The alkane monooxygenase AlkB catalyzes the chemoselective terminal hydroxylation of isoprenyl acetate. Rational enzyme engineering further increased the activity of the membrane enzyme.

Understanding the Occurrence and Transport of Current-use Pesticides in the San Francisco Estuary Watershed

open access: yesSan Francisco Estuary and Watershed Science, 2008
The occurrence and potential effects of current-use pesticides are of concern in the San Francisco Estuary watershed but our understanding of the spatial and temporal distribution of contamination is limited.
