Message from Prof. Cranshaw dated 7/23/15 Spottedwing Drosphila

Activity by spottedwing drosophila is starting to pick up and normally is most severe through August and early September. Raspberries and blackberries are most susceptible, but they can go into other small fruits.

Earlier today I was asked if there were any insecticide options for this useful for gardeners. I would like to share my response, following, which can also provide an interim recommendation until this fall when we have a formal fact sheet on this subject:

"Getting a CSU sheet on SWD for home gardeners is a very high priority for me. What has held me up is that I have been waiting to see if there is something new in research that gives us better options, as what we have is not very good at present. Also, we have been conducting surveys of the fruit of various ornamental trees/shrubs to determine which of these are important "non-crop" hosts, as well as doing year-round trapping to determine the life history in the state, and these are wrapping up.

"And, although there are insecticide options, I have been a little leery of recommending them because the main crops affected - caneberry crops - have staggered bloom (fruit in a stage needing protection are on the same plant with flowers). Which results in it being a "crop in bloom" whenever one were to apply a pesticide, which raises conflicts with visiting pollinators. So, any recommendations, in my mind, would have to have the directions that sprays for this insect only be made in the evening, after bees stop visiting the plants. and that is a difficult message to get across.

"That being said, the insecticides I feel would be most effective, are available to gardeners, and - if used to avoid direct application to visiting bees (in evening) - would have the active ingredients of either spinosad or acetamiprid. The Monterey product is one of the several spinosad products available in garden centers. Most acetamiprid products are in the Ortho line.

"And, in the interim I have been recommending a Cornell fact sheet that has a home gardener angle:


"There >will< be a CSU sheet next year.


Are YOU a beekeeper? You have an important role in honey bee health - keep your hive healthy! Request a FREE copy of "Integrated Hive Management for Colorado Beekeepers" which describes monitoring and diagnosis of pests and diseases in Colorado. For one or more hard copies, Email us!

Our good friends and colleagues at CSU have produced an excellent bulletin entitled " Integrated Hive Management for Colorado beekeepers". Despite the title, I think most everything in the bulletin is entirely applicable to Wyoming except for the pest monitoring calendar. We probably start a little later in the spring and end earlier in the fall for some pests. The electronic version PDF file of it can be downloaded here at the CEPEP pollinator protection page here:

Crucifer Flea Beetle Species Needed

I have had Prof. Cranshaw, of CSU, request assistance from us in Wyoming for a study he is doing on the major flea beetle species that plague crucifer plants in our gardens. The two species he is most interested in are in the genus Phyllotreta.

Here is what Phyllotreta cruciferae looks like http://bugguide.net/node/view/371022/bgimage

Here is what Phyllotreta pusilla looks like http://bugguide.net/node/view/899607/bgimage

He would like to have specimens of flea beetles collected from all over Wyoming. To be of use to science, he needs the location of where they were collected (physical address or geographic coordinates), the date of the collection, and who collected them included with each sample.

These are small active beetle that might require an insect net to catch. You can kill them in freezer and send them in a crush resistant package to Whitney. These beetles are hard bodied so they don't require alcohol for preservation. However, If they are dried out and rattle around inside a package the antennae and tarsi will break off so pad them with a little tissue to prevent that.

To send directly to Whitney use this address:

Thank you for any specimens you can gather. If you have question about this project don't hesitate to contact me or Whitney.
