Darwin's finches are highly innovative. Recently we recorded for the first time a behavioural innovation in Darwin's finches outside the foraging context: individuals of four species rubbed leaves of the endemic tree Psidium galapageium on their feathers. We hypothesised that this behaviour serves to repel ectoparasites and tested the repellency of P. galapageium leaf extracts against parasites...
Dengue and chikungunya are deadly diseases transmitted by Aedes aegypti. Essential oil a natural product contains highly volatile chemical compounds and use as a personal protection against blood sucking mosquito is an effective and safe method. The objective of these studies was to evaluate the synergistic effect of 10 effective oils with the help of K & D module and Electroantennogram (GCEAD)...

Water infiltration into granular soils and the associated pore water pressure increase reduction in shear strength can trigger landslides, instability of vertical cuts failure retaining walls. Water-repellent reduce to maintain soil suction. Recent research has demonstrated creation synthetic water-repellent using chemical methods. This paper investigates a biological treatment for creating san...
