摘要:
The black vine weevil,Otiorhynchus sulcatus(F.), preferred to oviposit in containers with Japanese yew,Taxus cuspidataSiebold and Zuccarini, cv. Densa, foliage over 10 other plant species when given alternating 5- or 7-d exposures. Host experience of larvae or prereproductive adults generally had no effect on their overall preference forTaxus.Weevils did not differentiate between pairs of most nonhosts but exhibited some preference for strawberry,Fragaria ananassaDuchesne. Females had to contactTaxusfoliage to be stimulated to oviposit. Antennectomized weevils were able to differentiate betweenTaxusandIlex crenata compactaThunberg foliage, but they laid a greater proportion of their eggs onIlexthan intact weevils. It is suggested thatT. cuspidataand possibly strawberry foliage contain an oviposition stimulant for the black vine weevil which is perceived only by contact or feeding.
