The biotype of the defoliating beetle, Altica carduroum, from Wusu Xinjiang, China was studied as a biocontrol agent for Cirsium arvense in Canada. At Wusu, the beetle is particularly damaging to C. arvense in irrigated crops and fallow fields. A release of 300 adult A. carduorum at Urumqi, Xinjiang, dispersed to cover an area with a radius of 600 m by the following year, where it destroyed almost 60 of C. arvense leaves and resulted in plant wilting at a density of 4.5 beetles plant. Laboratory studies of the beetle' s development of 2 C intervals from 15 to 27 C identified the optimum developmental temperature as 25.5 C. Beetles reared at this temperature laid an average of 245 eggs, with a 41-fold generation increase. Habitat comparisons between biotypes of A. carduorum from Wusu and Europe suggest that the Wusu biotype may be better suited as a biocontrol agent of C. arvense on the Canadian prairies. |
