The attraction of both male and female Plagithmysus bilineatus Sharp beetles to stressed ohia {Metrosideros polymorpha Gaudichaud) trees was studied on the island of Hawaii in 1979 and 1980. Ohia trunks were severed to determine if stressed ohia were more attractive to P. bilineatus than were nonsevered trees. Beetles initially were attracted to severed trees before they dem¬ onstrated any external signs ofstress. There was no host attraction or oviposition response to control trees. The number ofbeetle captures did not differ significantly between the upper and lower trap bands of stressed trees, the number of adult captures and subsequent larval infestations were not correlated. When adults were caged on severed and nonsevered trees, however, severed trees had a significantly greater abundance and survival oflarvae. |
