Led UF's mole cricket project during its initial years (1979-1985). During this period the origins, ecology, and behavior of Florida's three pest species were clarified, and the initial steps taken in what became their successful biological control by the introduction of natural enemies from temperate South America (Walker 1984).
Headed the faculty planning committee for the Entomology and Nematology Building (1986-1990).
Editor of Florida Entomologist (1964-1966).
Web Master of Florida Entomologist (1994-date).
Led the development, production, and installation of 56 computerized environmental
chambers (“Florida Reach-Ins”) (1987-1991) as described by Walker et al. 1993.
Developed and improved acoustical traps for agriculturally important insects (Walker 1988, 1996).
Showed that butterflies migrate into and out of peninsular Florida each
fall and spring by the tens of millions (Walker 1991).
Developed economical, effective, portable traps for monitoring butterfly
migration (Walker and Whitesell 1993, 1994).
Established that fall migrating cloudless sulfur butterflies fly different
compass directions appropriate to reaching peninusular Florida.
Analyzed the acoustical template of larvipositing Ormia ochracea. (Walker 1993).
Completed a database of the nearly 9,000 tape recordings of insect sounds in the Walker Tape Library. Most of the recordings have now been digitized and posted online by Cornell's Macauley Library of Natural Sounds.
Headed a project to electronically publish Florida
Entomologist on the Internet in parallel with its traditional version.
Successfully urged the Entomological Society of America to offer its authors, at a fair price, unlimited, immediate free Web access to their articles.
Headed a project
that made the 1917 to March 1994 issues of Florida Entomologist publicly
accessible on the Web. The cost of scanning, indexing, and optical
character reading the 20,000 pages was less than $12,000.
that the pulse rates in the calling songs of Gryllus rubens and G. texensis
were influenced by temperature during development.
Elected as Fellow of the American Association for the Advancement of Science in 1964.
