(1992) in Brazil evaluated an imported formulation of S. carpocapsae by spraying onto split pseudostems and pseudostem stumps as a baiting technique and observed 70% mortality of BWB adults. 2001. However, there is a paucity of information on developmental biology on preferred food substrate [1, 16]. For example, grandisoic acid, a male-produced aggregation pheromone, has played an important role in the monitoring and control of the plum curculio in apple orchards (Leskey et al., 2008). Figure 1.

While initial infestations of palms by the silky cane weevil is not usually lethal, we believe that the stress created by the infestation makes these palms susceptible to successful attack by the palmetto weevil. 2002.

At Barro Colorado Island in Panamá, three years of light trapping (Wolda et al., 1998) yielded 1240 species of Curculionoidea (excluding Platypodinae and Scolytinae, but including about 200 species from four other families). Mating behavior and sexual response to aggregation pheromone of, Weissling TJ, Giblin-Davis RM. The ratio varied from 1.2 to 1.5 across the four food hosts with a mean growth ratio of 1.3 on all the cereal crops used; these values showed that growth progresses at a constant rate in each molt which is relatively close to the constant Dyar’s ratio of 1.4 for lepidopterous insects although it has been adopted for other insect orders [26, 27]; the slightest difference observed could be because S. zeamais is a coleopteran.

Culture arenas were observed daily until new progenies emerged; they were removed and sexed using morphological characters described by Halstead [18]. and Latan (Latania spp.) In the laboratory, a palmetto weevil female will lay an average of 207 eggs in her lifetime. The great majority of weevils are endophytic; the few that feed directly on leaves often do so as leaf-miners. Photograph by Robin M. Giblin-Davis, University of Florida. & Bergström, G. 1986. In the United States, some cultivars of sweet potato are called yams, and these are susceptible to sweetpotato weevil. O’Brien, L.B. They can also be quite variable in overall size. 1988.
