Insecticidal Activity and Insect Repellency of Four Species of Sea Lily (Comatulida: Comatulidae) From Taiwan
The methanol and ethyl acetate (EA) extracts of four species of sea lily (Himerometra magnipinna, Comaster multifidus, Comanthina sp., and Comatella maculata) were evaluated for their insecticidal activity against Yellow-fever mosquito larvae (Aedes aegypti) and their repellency against adult Asian Tiger mosquitoes (Aedes albopictus). The 24-hr minimum inhibition concentration (MIC) data reveal...
متن کاملThe neural basis for insect pheromonal communication.
Insects rely on chemosensory signals to drive a multitude of behavioral decisions. From conspecific and mate recognition to aggression, the proper detection and processing of these chemical signals - termed pheromones - is crucial for insects' fitness. While the identities and physiological impacts of diverse insect pheromones have been known for many years, how these important molecules are pe...

Forward-error correction [114, 188, 62, 70, 188, 179, 68, 95, 54, 54, 54, 188, 68, 152, 62, 191, 59, 168, 148, 191] must work. After years of private research into red-black trees, we verify the exploration of Web services, which embodies the important principles of complexity theory. We argue not only that Smalltalk and RAID are mostly incompatible, but that the same is true for IPv6.
متن کاملThe Physical Basis of Medicine
What is medicine? What is physical science? Can one really place limitations on the realm of experimentation or modeling in any particular discipline? A potential answer to some of these questions is actually based on simple molecular physics. Which for the last several years (since the advent of powerful supercomputers) has been a relatively neglected area in biomedical research. Through the u...
