DEVELOPMENT OF HORSE CHESTNUT LEAFMINER (CAMERARIA OHRIDELLA DESCHKA & DIMIC) ON RED HORSE CHESTNUT

摘要

Observations on the development of the horse chestnut leafminer on red horse chestnut (Aesculus x carnea H.) were carried out in Wroclaw, Lower Silesia, Poland, in 2001-2003. Three generations of the pest were recorded to lay eggs on the red horse chestnut leaves. Although females of each generation deposited eggs abundantly, the hatching larvae died after a short period of feeding in the plant's leaves and the species did not complete its development on this tree. Mostly L_1 and L_2 larvae were found inside the leaf mines. The observed leaf damage was, therefore, negligible.
