摘　　要：1836年,Schmidberger首次发现蛀木质部小蠹是以坑道壁上排列的栅栏状物为食,由于弄不明白这些栅栏状物为何物,便将它们称为"ambrosia",意为"神的食物"(Fisher et al.,1953;1954;Schmidberger,1836)。1844年,Hartig明确了被北方材小蠹(Xyleborus dispar)幼虫取食的栅栏状物是丛梗孢属(Monilia)的一种真菌(Batra,1967)。此后,"ambrosia fungi",即"虫道真菌",便被广泛用于对生长在坑道中、为蠹虫所取食的真菌之称。Ambrosiella hartigii,Acremonium kiliense and Fusarium sp.were inoculated and cultivated on PDA in Petri dishes and on semi-artificial diet in test tubes for rearing Xylosandrus germanus larvae and adult females,respectively.Effect of the three species of ambrosia fungi on development and reproduction of X.germanus were studied.The results showed that the larvae were able to feed on three species of fungi and complete development,however,the larvae feeding on A.hartigii grew fastest and had the highest survival,while the larvae feeding on Fusarium sp.grew slowest and had the lowest survival,the survival was only 12.3%.The adult females were all able to reproduce offspring feeding on three species of fungi,however,the fecundity of the females feeding on A.hartigii was highest of three species of ambrosia fungi.
