Extract

Wilted stems of Eupatorium odoratum L., (Compositae) in Trinidad were found to contain an egg or lama of a Curculionid. Each egg was deposited in a slit between two rows of punctures encircling the stem. This girdling made by the ovipositing female was obviously the cause of the wilting. Larvae hatching from the eggs fed for a few days ih the wilted portion of the stem and then tunnelled into the sound tissue below the punctures completing development a month later, and pupating in the stem near the base of the plant. The adults, which emerged ten days later, were identified as Rhodobaenus sp. nr. cariniventris by Mr. R. E. Warner of the U.S. National Museum.
