The increasing prevalence of insecticidal products containing mixtures of active ingredients has highlighted the need for computational approaches to predict the insecticidal activity at specific dose combinations. Several models predicting the interactions have been proposed, each based on different assumption regarding mixture toxicity. However, the lack of consensus on which model to adopt for
Fruit flies and other miniscule flying insects often cause a nuisance in the kitchen areas of our dwellings. To mitigate the invasion of indoor insect pests, behavioral modifications using spatial repellents containing natural products are emerging as alternatives to chemical insecticides especially around the kitchens and food storage areas. However, the absence of standardized testing methods fo
Plant essential oils are intricate blends comprising predominantly of monoterpenes and some sesquiterpenes. These oils display diverse bioactivities against targeted organisms, often arising from complex interactions among their constituents, which may demonstrate synergistic or antagonistic effects. Despite their wide use as botanical insecticides, the mechanisms behind these interactions and the
In South Korea, control agents for small flying insects are subjected to approval under newly enforced Act on biocidal products by the Ministry of Environment starting from 2019, along with other conventional household insecticides. The present study aimed to evaluate 18 compounds for their toxicity and repellency in various contexts. A tube assay revealed the greatest toxicity of synthetic repell
Plant essential oils are widely acknowledged for their insecticidal activities and synergistic interaction with conventional insecticides, but their insecticidal modes of action and the mechanism of synergy remain less understood. In this study, electrophysiological screenings on the larval central nervous system (CNS) of the common fruit fly, Drosophila melanogaster, and the housefly, Musca domes
For the indoor and outdoor pest controls, various types of insecticide formulations are available including aerosols, sprays, electric vaporizers, mosquito coils, and traps. In the present study, the insecticidal activity of aerosols, the most commonly used formulation of household insecticides for mosquito control, against Aedes albopictus (Skuse) was assessed using seven commercial products and
Owing to the complexity in the chemical composition of plant essential oils, they often display enhanced insecticidal activity when applied as a mixture. Although the insecticidal activity of plant essential oils has been gaining more attention recently, understanding in the mechanism of synergy has not been studied as much. In the present study, insecticidal activity of 28 individual essential oi
This book challenges the prevailing notion of stability, cohesiveness, and uniformity within Christian communities, inviting readers to view contestation and disagreement as integral to theological reflection and church identity. While the volume focuses predominantly on the Roman Catholic Church as a case study, various chapters broaden the exploration across other Christian and non-Christian tr
Biodegradable plastic mulch films are increasingly adopted in agriculture, yet the ecotoxicological risks arising from their degradation products in mixtures with concurrent chemical inputs remain largely unexplored. This study assessed the lethal and sublethal toxicity of PBAT/PLA biodegradation products combined with four soil-applied insecticides (abamectin, cyantraniliprole, sulfoxaflor, and t
In an era of rapid change and increasing societal demands, the role of universities as knowledge producers and catalysts for change has come under scrutiny. This open access book offers a fresh perspective on the significance of universities in society, shedding light on how their knowledge can truly matter beyond academia.Drawing upon insightful inquiries from both the Swedish and international c
Lime-cement mixing is a method used for ground improvement of clay soils. Before mixing at a field site, laboratory samples are prepared and tested to decide the amount of lime-cement binder needed to reach the desired material strength. Strength measurements are not possible before a sample hardens, and the test process to predict final strength takes 30 days. Resistivity measurements are possibl
Does the level of attention that politicians direct toward complex environmental problems impact how frontline bureaucrats in municipal settings form relationships? The collaborative interactions among civil servants are a defining feature of environmental governance, drastically shaping how issues are addressed. In this article, the authors incorporate political attention, or the priority status
