Insecticide resistance in malaria and arbovirus vectors in Papua New Guinea, 2017–2022 by Michelle Katusele, Solomon Lagur, Nancy Endersby-Harshman, Samuel Demok, Joelyn Goi, Naomi Vincent, Muker Sakur, Absalom Dau, Lemen Kilepak, Stephen Gideon, Christine Pombreaw, Leo Makita, Ary Hoffmann, Leanne J. Robinson, Moses Laman, Stephan Karl

“…While widespread pyrethroid resistance in Anopheles and Aedes species has been described in many countries, data for Papua New Guinea (PNG) are limited. Available data indicate that the local Anopheles populations in PNG remain pyrethroid-susceptible, making regular IR monitoring even more important. …”

Coating formulation change leads to inferior performance of long-lasting insecticidal nets in Papua New Guinea by Nakei Bubun, Evodia Anetul, Melanie Koinari, Timothy W. Freeman, Stephan Karl

“…In a previous study, the authors demonstrated a substantial decrease in the bioefficacy of LLINs for malaria prevention delivered to Papua New Guinea (PNG) between 2013 and 2019. This coincided with a rise in malaria cases in the country. …”

Genetic differentiation and bottleneck effects in the malaria vectors Anopheles farauti and Anopheles punctulatus after an LLIN‐based vector control program in Papua New Guinea by John B. Keven, Rebecca Vinit, Michelle Katusele, Lisa J. Reimer, Peter A. Zimmerman, Stephan Karl, Edward D. Walker

“…Abstract Implementation of long‐lasting insecticide‐treated net (LLIN) programs to control human malaria transmission leads to substantial reductions in the abundance of Anopheles mosquitoes, but the impact on the population genetic structure of the malaria vectors is poorly known, nor has it been investigated in Papua New Guinea, where malaria is highly endemic and where several species of Anopheles have vector roles. …”

A cross-sectional study to ascertain malaria prevalence among asymptomatic travellers arriving on the Lihir Group of Islands, Papua New Guinea: implications for elimination efforts by Pere Millat-Martínez, Bàrbara Baro, Bernadine Kasian, Lina Lorry, Sergi Sanz, Chilaka Wali, Sylvia Raulo, Arthur Elizah, Tamarah Koleala, Maria Kaius-Ome, Stephan Karl, Oriol Mitjà, Moses Laman, William Pomat, Quique Bassat

“…Abstract Background The Lihir Islands of Papua New Guinea host a mining operation that has resulted in a mine-impacted zone (MIZ) with reduced malaria transmission and a substantial influx of mine employees, informal cross-country traders, returning locals, and visitors. …”

Analysis of insecticides in long-lasting insecticidal nets using X-ray fluorescence spectroscopy and correlation with bioefficacy by Melanie Koinari, Nakei Bubun, David Wilson, Evodia Anetul, Lincoln Timinao, Petrina Johnson, Petrina Johnson, Norelle L. Daly, Moses Laman, Tim Freeman, Stephan Karl, Stephan Karl

“…The main aim of the present study was to determine the utility of X-ray fluorescence (XRF) spectroscopy as a suitable field-deployable tool for total AI quantification in LLINs.MethodsNew and unused LLIN samples containing deltamethrin (PermaNet® 2.0, n = 35) and alpha-cypermethrin (SafeNet®, n = 43) were obtained from batches delivered to Papua New Guinea (PNG) for mass distribution. Insecticides were extracted from the LLINs using a simple extraction technique and quantified using liquid chromatography mass spectrometry (LC-MS). …”

WHO cone bioassay boards with or without holes: relevance for bioassay outcomes in long-lasting insecticidal net studies by Melanie Koinari, Nakei Bubun, Brogan Amos, Kiari Kiari, David Lahu, Stephan Karl

“…Assays with Anopheles farauti were done at the Papua New Guinea Institute of Medical Research (PNGIMR) and assays with Aedes aegypti were done at James Cook University, Australia. …”
