1 Semiochemicals are powerful tools for the surveillance and suppression of forest insects. Although the literature on the chemical ecology of and use of semiochemicals to manage the Cerambycidae is growing, little is known about the chemical ecology of Cerambycidae fauna in Peru. 2 Trapping studies that screen known attractants in off-shore mitigation programs can provide valuable baseline knowledge to inform management of species introduced outside their native range. 3 Known Cerambycidae pheromones were screened for activity in a year-long field study in Peru to look for activity in the local Cerambycidae fauna. 4 The most frequently captured species were Megacyllene andesiana (Casey), Oreodera bituberculata Bates, Aegomorphus longitarsis (Bates) and Discopus eques Bates. 5 The activity period of A. longitarsis, O. bituberculata and D. eques occurred in mid-September 2020 and for M. andesiana occurred in early October 2020. 6 Responses to anti-2,3-hexanediol, fuscumol and fuscumol acetate by M. andesiana, O. bituberculata and D. eques were observed. 7 We observed antagonism of the responses of M. andesiana, O. bituberculata and D.eques when anti-2,3-hexanediol, fuscumol and fuscumol acetate were tested in blends.
The objective of this study was to select native isolates of entomopathogenic fungi against adult Cosmopolites sordidus in laboratory conditions. Four isolates of Beauveria bassiana, two isolates of Metarhizium anisopliae, and two isolates of Paecilomyces lilacinus were tested against C. sordidus. The entomopathogenic fungi that resulted in mortality rates over 50% were M. anisopliae (MA-CsCha and MA-Carabid) and B. bassiana (BB-CsCha and BB-CsLp). The most virulent isolates were MA-CsCha, BB-CsCha, and MA-Carabid with median lethal times (LT50) of 4.82, 5.4, and 5.79 days, respectively. In conclusion, the MA-CsCha, BB-CsCha, MA-Carabid, and BB-CsLp isolates are viable candidates to be tested in banana fields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
