The ultrastructural and biochemical characteristics were studied in active and diapausing pupae of the horse chestnut leaf miner, Cameraria ohridella, collected in summer. The active pupae contained developing internal organs, while those in diapause

This study of the proteins in the silk of the summer and winter cocoons of the horse chestnut leaf miner Cameraria ohridella revealed they can inhibit protease activity. The inhibitory activity of the summer silk was higher against both the fungal pr

In this study, we tested the hypothesis that a micro-serrated edge on the honey bee Apis mellifera stinger tip serves as a tool for more intensive crushing of cell membranes in the victim's tissues. This could have mechanical consequences as well as
