Pyrethroid Resistance Associated with a Decreased DEET Repellency in the Common Bed Bug (Hemiptera: Cimicidae)
(Oxford University Press, 2019-03)
The global resurgence of the bed bug (Cimex lectularius L.) and the widespread resistance of this insect to pyrethroid insecticides have created the need to find alternatives to chemical control. Thus, synthetic or natural ...
Electrospun ethylcellulose-based nanofibrous mats with insect-repellent activity
(Elsevier Science, 2019-10)
Mosquito repellent textiles are increasingly in demand from consumers as protective textiles against mosquito-borne diseases like malaria, yellow fever or dengue. In this work, the production and behaviour of repellent-containing ...
Behavioural responses of Vespula germanica (Hymenoptera: Vespidae) wasps exposed to essential oils
(Blackwell Publishing, 2015-12-01)
Secondary plant metabolites such as those present in essential oils can be toxic to herbivorous insects and also repel attack, given they play a role in selection and acceptance of host plants. However, few studies have ...
Insecticidal and Insect-repellent Activities of Essential Oils from Verbenaceae and Anacardiaceae Against Rhizopertha dominica
(Natural Products Inc., 2009-09)
Essential oils extracted from leaves of Aloysia polystachya and A. citriodora (Verbenaceae) and from leaves and fruits of Schinus molle var. areira (Anacardiaceae) were tested for their repellent and toxic activities against ...
Toxicity of pyrethroids and repellency of diethyltoluamide in two deltamethrin-resistant colonies of Triatoma infestans Klug, 1834 (Hemiptera: Reduviidae)
(Fundação Oswaldo Cruz, 2006-02)
The aim of the currrent investigation was to evaluate (a) the toxicity of three pyrethroids (deltamethrin, lambdacyhalothrin, and tetramethrin); (b) the effect of these insecticides on the locomotor activity; and (c) the ...
Plant-based compounds with potential as push-pull stimuli to manage behavior of leaf-cutting ants
(Wiley Blackwell Publishing, Inc, 2017-05)
Leaf-cutting ants are a serious pest of young forestry plantations. Currently, the main control method is the use of broad-spectrum insecticides, which have a negative effect on non-target organisms and the environment. ...
Spatial Repellency Caused by Volatile Pyrethroids is Olfactory-Mediated in the German Cockroach Blattella germanica (Dictyoptera: Blattellidae)
(Sociedade Entomológica do Brasil, 2019-10)
Pyrethroids are synthetic insecticides that have a repellent action. This effect has been associated with an increase in the locomotor activity, which causes the avoidance of the insecticide-treated area (excito-repellency). ...
Fabrication of superhydrophobic and ice-repellent surfaces on pure aluminium using single and multiscaled periodic textures
(Nature Publishing Group, 2019-12)
Fabricating aluminium surfaces with superhydrophobic and ice-repellent properties present nowadays a challenging task. In this work, multifunctional structures are manufactured by direct laser writing and direct laser ...
Soil stabilisation by water repellency under no-till management for soils with contrasting mineralogy and carbon quality
(Elsevier Science, 2019-12)
No-till soil management is common around the globe, but the impacts on soil structural quality varies depending on cropping practice and inherent soil properties. This study explored water repellency as a driver of soil ...
Repellency Assays with Schinus molle var. areira (L.) (Anacardiaceae) Essential Oils against Blattella germanica L. (Blattodea: Blattellidae)
(Entomological Society of Brazil, 2009-07)
Plant extracts have been used all over the world as an alternative method to control pests. In our study, essential oil extracted from leaves and fruits of Schinus molle var. areira (L.) (Anacardiaceae) was tested for ...
