Dealing with Blister Beetles

Blister beetles, from the family Meloidae, are sometimes referred to as oil beetles and found in all parts of the Unites States and Canada. Adult blister beetles vary in size and color but are recognized by the elongated, narrow, cylindrical, and soft bodies. In Nebraska, the three-striped, grey, and black blister beetles (Fig. 1) are the most common species. Blister beetles produce a chemical called cantharidin which is toxic to animals and humans. The male blister beetle secretes cantharidin and presents it to the female after mating.

Checking Water from Afar

For cattle producers who rely on wells in pastures and rangelands as a water source for their cattle, much time is spent checking water to make sure that windmills and submersible wells are delivering the water cattle need.   These water checks are often made daily or every other day to ensure water is available.  When problems occur with a water source cattle depend on, time is limited to get the problem fixed, haul water or move the cattle to another location where water is.  Timeliness of knowing there is a problem with a well or a tank that stores water is essential

Managing Bull Fertility Prior to the Breeding Season

As we prepare for the breeding season or for those in the midst of the breeding season, it is important to think about how we can manage bull fertility and understand critical factors that can impact fertility. There are many factors that can affect sperm production; however, the main factors that can decrease sperm production are disease, fever, injury, and extreme environmental conditions. We must keep in mind that spermatogenesis, the production of sperm, is a 61-day process in bulls; therefore, it will take upwards of 60 days to have normal sperm again following an injury/insult.

Musk Thistle

Early Detection and Rapid Response (EDRR) is a concept to identify potentially invasive species prior to or just as the establishment of the invasive is taking place.  An Integrated Pest Management plan (IPM) can be developed to manage, contain and eradicate the invasive species before it can spread further.  This will avoid costly, long-term control efforts.

Musk Thistle  
a.k.a. – Nodding thistle, Nodding Plumeless thistle 
Scientific name:  Carduus nutans L.
Family:  Asteraceae (Sunflower family)

Fermenting for Forages: Small Grain Silage

When the term silage is used, typically what comes to mind is corn silage. This is especially true in the Great Plains and Midwest where corn is king. Another silage that may be less known is small grain silage.

Fermenting for Forages: Finding the Right Moisture

Developing cattle rations without distillers products to provide moisture and protein is an issue on many producers’ minds.  One option this summer is to cut fall planted rye or spring oats, wheat, triticale, or barley for silage.   Small grain silage can add moisture and some protein to rations and help fill the gap before corn silage is ready to harvest this fall.

Field Bindweed

Early Detection and Rapid Response (EDRR) is a concept to identify potentially invasive species prior to or just as the establishment of the invasive is taking place.  An Integrated Pest Management plan (IPM) can be developed to manage, contain and eradicate the invasive species before it can spread further.  This will avoid costly, long-term control efforts.
