Biology and Control of the Horse Chestnut Leaf Miner Moth Cameraria Ohridella

Synopsis: Cameraria ohridella (Gracillariidae), the horse chestnut leaf miner, causes severe damage to horse chestnut trees. Its biology and the host-parasite-relationship have been investigated in the HAMburg-CAMeraria-Project (www.cameraria.galk.de), the results are presented in this video. The following topics are described in detail: the single developmental stages of the horse chestnut leafminer (egg, larval stages, spin larva spinning a "cocoon", pupa and imagines); damage to chestnut trees by larvae feeding on chestnut leaves; determination of the population density, population dynamics and the control of the moth. The video contains several REM shots which reveal morphological details of the developmental stages of Cameraria ohridella as well as microscopic shots.

The collection is particularly strong in the areas of scientific and ethnographic films. The films are in German but many are also available with English commentaries. Programmes are available for sale on DVD, video or CD-ROM and some can be previewed free online. There is also an online Media Library of Cell Biology (http://www.iwf.de/IWF/Media/Cellbiology.htm) supplying digital media in various formats.
