“…Attractants such as fungal extracts (Esenther et al, 1961;Cornelius et al, 2004;Su, 2005) and carbon dioxide at10-12 mmol/mol (Bernklau et al, 2005) has been shown to improve the attractiveness of bait to termites. As a means to increase consumption, phagostimulants that made the bait more palatable, such as urea (Waller, 1996) amino acids (Chen & Henderson, 1996), and sugars (Morales-Ramos & Rojas, 2003a;Waller & Curtis, 2003;Saran & Rust, 2005, were also explored. Termites fed more on baits with additives than those without.…”
