We had a pasture fly IPM meeting with Aaron Gabriel in Washington County last Thursday. We had a great turnout of 13 producers and 2 veterinarians. The host farm is an organic dairy producer and there were 10 other organic producers.

Horn flies, face flies and stable flies are the 3 main pasture flies causing cattle issues in the fields. At this farm there were a lot of stable flies. Prime habitat for stable fly breeding is where grass/hay comes in contact with the soil. As seen in the following photo this habitat was plentiful.

On the plus side, there were also many dung beetles in the manure pats. The following photo shows holes created by dung beetles on the top of a manure pat. More on dung beetles see article below.

The temperatures were 0 to 3 degrees above normal for most of the state. Precipitation ranged widely from only 0.01 inches to over 3 inches. The heaviest rain was in the Northern Plateau, Mohawk Valley, and northern Eastern Plateau from thunderstorms. The base 50 growing degrees ranged from 100 to 150.
Today high pressure will bring sunny skies and warmer temperatures into the mid 70's and low 80's. Overnight temperatures will drop into the mid 40's to mid 50's.
Friday will be sunny with temperatures in the upper 70's to mid 80's. Lows will range from the low 50's to low 60's.
Saturday's highs will be throughout the 80's nearing 90 with a possibility of showers and thunderstorms as frontal systems pass through. Lows will be in the upper 50's and low 60's.
Sunday's temperatures will be throughout the 80's with showers & thunderstorms possible again. Lows will be in the 60's.
Monday's highs will be in the low to mid 80's with showers & thunderstorms possible. Overnight temperatures will be in the low 60's.
Tuesday will have highs will be in the low to mid 80s with lows in the low to mid 60's.
Wednesday's temperatures will be in the low to mid 80's with showers possible. Overnight temperatures will be warm in the mid 60's.
The five day precipitation amounts will range from a tenth to half an inch. The 8-14 day outlook is showing above normal temperatures for the southern border of the state and above normal precipitation for just southwest corner of the state.
Face flies and horn flies, two key fly pests attacking cattle on pasture, both complete their egg, larval and pupal stages in cow manure. These two fly pests are, however, frequently not alone – about 450 arthropod species have been reported to inhabit cow pats. Why dig through manure to find dung beetles? Dung beetles are very important insects that help decompose cattle manure and aide in recycling nutrients in pastures. Dung beetles compete with other organisms like pest flies for resources within the manure, thus limiting successful pasture fly development. Dung beetles help recycle the manure back into the soil providing nutrients for the pasture grasses to continue to grow and produce forage. Having a good population of dung beetles is an indication of a healthy pasture. There are three types of dung beetles that can occupy a dung pat:
Rollers (telecoprids) Geotrupes species, form balls of manure which they push from the pat to bury as brood balls
Tunnelers (paracoprids) Onthophagus species are tunnelers that consume the pat and burrow beneath it to bury brood balls.
Dwellers (endocoprids) Aphodius species, consume the manure as they tunnel within the dung pat and oviposit eggs in the manure or surrounding soil. Most dung beetles found in NY are dwellers.

Some feed-through insecticides can have detrimental effects on manure inhabiting arthropods. These materials are not always completely metabolized in the body and are dispelled into the manure pat. To enhance dung beetle populations try to select fly control methods and products that help preserve dung beetles in your pastures.
As mentioned in last weeks WPR, we have a statewide effort on the lookout for western bean cutworm moths. Western bean cutworm (WBC) is an emerging pest in NY, with the potential to cause substantial damage to corn, Zea mays and beans, Phaseolus vulgaris.
Researchers in Ontario Canada and Indiana reported first WBC trap catches during the week of June 23 in a few of their monitoring stations. This week WBC moths were captured in New York and Pennsylvania. In NY, WBC moths were collected one each in Ithaca (Tompkins County) and Kennedy (Chautauqua county). This was about the time of our first WBC collections last year and while numbers of WBC collected are small, the finds signal that the 2011 WBC season has begun.
Economically important infestations of this insect are not expected in 2011. The question remains, however, will the insect be found again this season?, where?, in what numbers? and what will it mean to our producers?
Our NY trapping program will continue through August. Results of the regional trapping network will soon be posted at the Sweet Corn Pheromone Trap Network Report (ECB, CEW, FAW, WBC), and Pennsylvania State University's Pest Watch website. Stay tuned for more information.
Alfalfa and Grass Hay:
Cattle on Pasture:
Dairy Cattle Barn Fly Management:
*Check facilities for favorable fly breeding conditions: (organic matter + moisture): leaks in watering systems, roof gutters for leaks and potential overspill, drainage,
*Sanitation, sanitation, sanitation - clean animal resting areas, feed troughs, minimize source of moist organic matter i.e. fly breeding areas in barn and in adjacent animal loafing yard
*Use, replenish, replace fly management materials: sticky fly tapes/ribbons, insecticide baits, natural enemies (parasitoids), fly population monitoring (3 x 5) spot cards
*Consider purchase and release of Muscidifurax raptor and/or M. raptorellus natural enemies of house and stable fly pupae.
