Insecticidal and repellant activities of selected botanical extracts against rice weevil (Sitophilus oryzae L.)
… and lower toxicity. This study investigated repellence activity, insecticidal activity and phytochemical composition of acetone and ethanol extracts of basil leaves (Ocimum basilicum), turmeric leaves (Curcuma longa) and akar mempelas stem (Tetracera macrophylla) against adult rice weevil …

Assessment of Bioactivity of Se-lected Plants against Pests and Microbes from Agro-pastoral Communities in Mbulu District, Tanzania
… generation (F1) progeny, feeding deterrence and repellence against selected storage pests and quality grains evaluation as well as phytochemicals profiles were determined using standard proce-dures. A total of 66 dentifies plant species mainly from Minosoidaceae, Solanaceae, and Euphobiaceae …

Design & Fabrication of Super-Hydrophobic Surfaces by Laser Micro/Nanoprocessing
… surfaces exhibit the property of high water repellence. In nature, lotus leaf and other plants have super-hydrophobic surfaces with self-cleaning effect. Taking inspiration from the surface properties of the lotus leaves, the ways to design and fabricate artificial super-hydrophobic surfaces …

Wood cell wall modification with hydrophobic molecules
… shown to improve dimensional stability, water repellence and/or durability, thus increasing potential service-life of wood materials. However current treatments are limited because it is difficult to introduce and fix such modifications deep inside the tissue and cell wall. Within the scope of …

Investigations into the oviposition behaviour of the mosquito Anopheles gambiae
… to bacterial solutions, but demonstrated repellence to 4-methylphenol at 1mg/ml. GC-EAG demonstrated a strong electrophysiological response to 4-methylphenol and 8 of the 9 bacterial chemicals tested gave at least 50% of the 4-methylphenol response. Direct observations of oviposition in a …

Effect of polyacrylamides on the physical properties of some light-textured soils.
… the water retention characteristic), on water repellence of the soils (by measuring water droplet penetration times), and the kinematic viscosity of the PAM solutions at various concentrations with various qualities of irrigation water. I also set up transparent cases of sand to observe …

A new perspective of environmental stress in heterogeneously contaminated landscapesbeyond the individual effect
… concepts into ERA, including avoidance/repellence and preference behaviors (from a habitat selection perspective), the meta-ecosystem framework (considering habitat heterogeneity and connectivity), colonization (focusing on ecosystem recovery and attractiveness), and habitat …

Experience with the association of volatiles with food does not affect response in three insect predators
Predadores e parasitóides de artrópodes herbívoros utilizam vários odores durante a busca por presas, tal como feromônios sexuais e de agregação de suas vítimas, assim como voláteis de plantas cuja produção é induzida pela herbivoria. Insetos são capazes de detectar uma vasta gama de compostos …
