Abstract:

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.

Key words: Xylosandrus germanus, Ambrosiella hartigii, Acremonium kiliense, Fusarium sp., development, reproduction
