...e the intruder. Macrophages, cells whose job is to devour such intruders, are attracted by substances typical of bacteria, which surround the microbe like a cloud. As soon as the immune cells have detected the intruder, they cover the bacterium with part of their own cell membrane like a hood, creating a me...Beneficial Beetles Battle Pesky Saltcedar
... where the troublesome tree is native--the beetles devour saltcedar's scale-like leaves. That happens when the insect is in its caterpillar-like larval stage or has matured into a quarter-inch-long adult beetle. Besides disrupting the natural surroundings needed by native plants, birds, fish and other form...Experiments provide proof of how traveling in groups protects insects
