A low-cost repellent for malaria vectors in the Americas: results of two field trials in Guatemala and Peru [PDF]

, 2007
Background: The cost of mosquito repellents in Latin America has discouraged their wider use among the poor. To address this problem, a low-cost repellent was developed that reduces the level of expensive repellent actives by combining them with ...

Smart insects repeller

Indonesian Journal of Electrical Engineering and Computer Science, 2020
<span>One of the key issues for those involved in farming and greenhouse is the use of pesticides. In a recent headline, there has been an epidemic of insect infestation that has destroyed 211 hectares of rice plants. These concerns have led to the discussion of possible over-use of pesticides that are not just killing dangerous pests, but also ...

Repellents against Aedes aegypti bites: synthetic and natural origins

Frontiers in Insect Science
Dengue fever, transmitted by mosquitoes of the Aedes genus, particularly Aedes aegypti, has emerged as a global health issue. With the expansion of this mosquito to new geographical areas, driven by factors such as climate change, the need for preventive

Promising Aedes aegypti repellent chemotypes identified through integrated QSAR, virtual screening, synthesis, and bioassay. [PDF]

PLoS ONE, 2013
Molecular field topology analysis, scaffold hopping, and molecular docking were used as complementary computational tools for the design of repellents for Aedes aegypti, the insect vector for yellow fever, chikungunya, and dengue fever. A large number of

Evaluation of synthetic repellents on mosquito nets in experimental huts against insecticide-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes.

, 2006
Owing to the development of pyrethroid resistance in Anopheles gambiae, there is a need to develop chemical alternatives for use on mosquito nets. Synthetic insect repellents are widely used for personal protection as skin or clothing applications.

Opportunities for integrated pest management to control the poultry red mite, Dermanyssus gallinae [PDF]

, 2011
Dermanyssus gallinae is the most economically important ectoparasite of laying hens in Europe. Control of D. gallinae is already hampered by issues of pesticide resistance and product withdrawal and, with the prohibition of conventional cages in 2012 and

Multifunctional Properties of Wintergreen (Gaultheria procumbens) Essential Oil: Antimicrobial, Antibiofilm, and Insecticidal Effects

Flavour and Fragrance Journal, EarlyView.
Unveiling the potential of Wintergreen (Gaultheria procumbens) essential oil. ABSTRACT This study investigated the antimicrobial, antibiofilm, and insecticidal properties of wintergreen (Gaultheria procumbens L.) essential oil (GPEO). The EO was chemically characterized by GC–MS, confirming methyl salicylate as the predominant compound (99.3%).

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...
