Another Beetle Pest
Last week my wife and I went to Big Cedar near Branson and I was surprised to see Japanese beetles all over the plantings. This insect is a major pest back East because it will eat just about any garden plant and loves roses.
Since I have not seen this beetle in Lawrence, I decided to see what's known about its distribution in Kansas. It turns out there is a very nice data base called NAPIS, the National Agricultural Pest Information System. or "Pest Tracker". Looking up Japanese beetle gives an information link with pictures of the sort of damage the grubs can do to lawns, tips for controlling the insect. They don't mention what we used to do when I was young namely pick the beetles off and plop them in jar of rubbing alcohol.Alas, there don't seem to be any quick fixes, but that is typical for most pest species. Instead the suggested approach outlined here is an Integrated Pest Management (IPM) approach. IPM involves monitoring larval and adult populations, cultural practices, and yes judicious use of appropriate pesticides and where practical biological control with parasites that attack the grubs and adults. Pest Tracker also has a recently updated distribution map for the Japanese Beetle. http://worldonline.media.clients.ellingtoncms.com/img/blogs/entry_img/2008/Aug/08/japbeetlemap.gifLook at the full sized map here.Notice the beetle is widespread in the East and it appears to be moving into Kansas. In Douglas County, it has been found in surveys. There is one hot area of infestation, namely Wichita and the Kansas Department of Agriculture blames infested nursery stock for this.So look at the picture carefully. The quarter to half inch long beetle is easy to identify by the white markings on the side of the abdomen, the greenish metallic thorax and orange wing covers. If you see it, I'd suggest collect one for verification, contact the local extension bureau for advice and don't bring uninspected plant material from another area into Kansas.
