Bark Beetle Research
Many of Hopkins early research consisted of qualitative observations of the beetle family. Hopkins most famous bark beetle observation was coined the Hopkins' host-selection principle (HHSP), which refers to the observation that many adult insects demonstrate a preference for the host species on which they themselves developed as larvae. However, the practicality of HHSP has been debated significantly since its first proposal in 1916. Many modern scientists have even discounted the evidence that supports HHSP as speculation. Although he has written dozens of well renowned publications, Hopkins most popular on bark beetles include the “Catalog of West Virginia Scolytidae (Bark Beetles) and Their Enemies" and "Catalog of West Virginia Forest and Shade Tree Insects."

Famous quotes containing the words bark, beetle and/or research:
“His life itself passes deeper in nature than the studies of the naturalist penetrate; himself a subject for the naturalist. The latter raises the moss and bark gently with his knife in search of insects; the former lays open logs to their core with his axe, and moss and bark fly far and wide. He gets his living by barking trees. Such a man has some right to fish, and I love to see nature carried out in him.”
—Henry David Thoreau (1817–1862)
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“The working woman may be quick to see any problems with children as her fault because she isn’t as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesn’t have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)
