Chrysomela populi L. ve Chrysomela tremulae F. (Col.:Chrysomelidae) erginlerine konukçunun etkisi.

In this study, the effects of various hosts on adults of Chrysomela populi L. and C.tremulae F. (Col.:Chrysomelidae), important poplar pests in Central Anatolia Region, were investigated. The studies were carried on four hosts ( Populus nigra L., P. x euramericana (Dode) Guiner, P. alba L. and Salix babylonica L.) at 24±1°C and 65±5 % R.H. and 18 h photoperiod. Average total number of eggs laid by each female was found to change between 32.90-989.18 in C.populi , and between 571.80-1320.10 in C.tremulae . The life longevity was found to change between average 45.00-54.18 and 2.67-106.70 days in the females, 48.30-71.70 and 91.96-123.68 days in the males in C.populi and C.tremulae , respectively. Fertility tables of females of the two species were made for different hosts, and biological parameters were determined. Studies showed that P. x euramericana was sensitive and P.alba was resistant for both species if only the poplar species were taken in hand.
