“…Pubescence traits can mediate various aspects of the plantÐ herbivore interaction, including herbivore attraction to the host plant (Southwood 1986), adult attachment and/or oviposition (Callahan 1957, Webster et al 1975, Roberts et al 1979, Robinson et al 1980, Gannon et al 1994, Haddad and Hicks 2000, Malakar and Tingey 2000, egg survival (Poos andSmith 1931, Schillinger andGallun 1968), insect growth (Lambert et al 1992, Malakar andTingey 2000), insect movement (Webster et al 1975, Eisner et al 1998, Zvereva et al 1998, insect survival (Gilbert 1971, Eisner et al 1998, Haddad and Hicks 2000, and pupal mass (Malakar and Tingey 2000). However, far from being a general defense, the effect of pubescence may be positive, negative, or nonexistent, depending on the particular herbivore species (Southwood 1986, Hare andElle 2002) and the leaf hair type (glandular or nonglandular), density, and length (Andres and Connor 2003).…”
