Voigt (Cucurbitaceae) first appeared on Guam in the 1980s and subsequently spread to about 200 ha in the absence of natural enemies. Following its successful introduction as a biological control agent in Hawaii, the weevil Acythopeus cocciniae O'Brien and Pakaluk (Coleoptera: Curculionidae) was brought to Guam under quarantine for host specificity testing against the endemic cucurbit, Zehneria guamensis (Merrill) Fosberg (Cucurbitaceae) and for further biological characterization. A. cocciniae preferred C. grandis over Z. guamensis in single- and two-host choice tests. No larval feeding was ever observed on Z. guamensis plants in two-host tests, and the single instance of A. cocciniae feeding on Z. guamensis in single-host tests was likely to avoid starvation. In 2004, A. cocciniae at the initial field release site in northern Guam dispersed primarily downwind in accordance to the prevailing northeasterly trade winds. However, only a single vine with a few adult weevils, larvae, and pupae were found at this site four years later in January 2008. This decrease was attributed to suppression by A. cocciniae. Since its initial release in 2004 A. cocciniae has established and dispersed throughout Guam.10aAcythopeus cocciniae1 aBamba, J., P.1 aMiller, R., H.1 aREDDY, G., V.

In a field experiment at eight different locations (Dededo, Tumon, Yigo, Hagåtña, Mangilao, Yona, Agat and Malesso), plastic bucket traps baited with the lure of the Australian R. obscurus population in combination with a food volatile compound (ethyl acetate) and cut sugarcane captured significantly more weevils (total of 348) than traps baited with pheromone lure of the Hawaiian R. obscurus population in combination with food volatile and cut sugarcane which caught a total of 128 weevils. Traps baited with lure containing only the food volatile and cut sugarcane or only cut sugarcane captured significantly fewer weevils (total of 36 and 30, respectively) than those baited with pheromone compounds. Data from trap catches indicate that the Guam population of R. obscurus responded significantly more to the pheromone lure of the Australian population than to pheromone lure of the Hawaiian population indicating that the Guam R. obscurus population is related more closely to the Australian population. Trap catches at the Tumon and Dededo locations were greater than those in Yigo, Yona, Mangilao, Hagåtña, Agat, and Malesso.
