We've seen fall armyworms moving in a few pastures recently. The threshold for this insect is about 2-3 caterpillars per square foot, fewer if the grass is young. The armyworms tend to be easier to see and are more actively feeding in the early morning or when it's cooler and cloudy out. On hot days check low in the canopy for caterpillars.

Our recent pop up showers have led to an increase in mosquito numbers in places. We have several species of mosquitos in our area, and all of them breed in standing water. It doesn't take much water to provide an adequate spot for mosquitos to breed.

Our mosquito populations are high right now. The two smaller mosquito species pictured above (Aedes sp.) are active throughout the day and into the evening, and will preferentially feed on humans. They can breed in very little water, and can reproduce quickly. Our first line of defense against mosquito borne illness is remembering the "Four Ds".
Dr. Sonja Swiger, our Agrilife extension entomologist at Stephenville states "Using products containing DEET, picaridin, oil of Lemon eucalyptus, or IR3535, as active ingredients provide reasonably long-lasting protection from mosquito bites." Be sure to read and follow the label for any product you use.
