Web-wormsFall webworms build unsightly webs that fill tree tops in the fall of the year. To control them, cut down the webs and destroy them.

Control fall webworms and rid trees of webs


By William G. Tyson for CAES News

Are you noticing webs in some of the trees throughout your landscape? I always get multiple calls during the late summer and early fall about webs in trees and worms crawling on everything. The fall webworm is the pest weaving these problems.

Two types of caterpillars make webs in trees – Eastern tent caterpillars and fall webworms. The Eastern tent caterpillar is more of a problem in the spring, and the fall webworm is more of an issue in the late summer/early fall.

Native to North America, fall webworms can produce from one to four generations per year. Webworms enclose small branches and leaves in their light gray colored webs. It’s not considered a major economic pest in forestry, but it can heavily defoliate shade trees and ornamentals. Its webs are unsightly, and constant infestations of individual trees will cause limb and branch diebacks.

The fall webworm feeds on more than 100 species of trees and ornamentals. Pecan, oak and fruit trees are their preferred hosts in our area.

Adult moths appear from May through August and deposit their eggs in hair-covered masses on the underside of leaves. The larvae are a pale yellowish-green with a dusky strip down the back and a yellow stripe down each side.

As the worms mature, they become covered with long gray hairs. Their head color varies from red to black. The newly hatched larvae spin a web over the foliage on which they feed for protection against predators. On heavily infested trees, webs may be found on several branches. The webs they build in trees stay around long after the worms leave.

Webs in trees stick out like a sore thumb, but damage to most trees is usually insignificant.

The best control method is to cut the web out of the tree, with the worms in it, and destroy it. Several chemicals will control webworms but may not be practical due to problems related to applications in larger trees. If you do spray to control the caterpillars, it is best to get good coverage, spraying the insecticide inside the webs to kill the pests.

Research has demonstrated that proper dry-off methods are vital in promoting udder health during the nonlactating period and at calving. For high producing cows, it may be necessary to decrease dietary energy over the last 1-2 weeks of lactation by increasing fiber and eliminating grain. Abrupt cessation of milking is probably as good as intermittent milking with a diet change for low and medium producing cows; however, intermittent milking is recommended for high producing cows to decrease milk yield and minimize leakage at dry-off, which could lead to mastitis. First lactation cows should be given a 50- to 60-day dry period, but multiparous animals fare well with a 35- to 45-day dry period. Selective dry cow therapy with non lactating cow antibiotics plus teat seal is as effective as blanket dry cow therapy with non lactating cow antibiotics plus teat seal for cows with SCC less than 200,000/ml. However, blanket dry therapy with both products is recommended for cows that dry off with greater than 200,000/ml. It is important to follow recommended infusion techniques to preserve the protective components of teat canal keratin and the sphincter muscle. And lastly, use of coliform vaccines will enhance immunity over the dry period and reduce clinical coliform mastitis in early lactation. This publication address these topics in more detail in order to help producers prevent mastitis in their dairy herds.

Prevalence of mastitis in dairy goats ranges between 5% and 30%, with Staphylococcus spp., otherwise known as the coagulase-negative staphylococci, identified as the most frequent cause of infection. These staphylococci produce persistent subclinical mastitis with markedly elevated somatic cell counts (SCC), which may lead to clinical symptoms. Prevention is the key to controlling staphylococcal mastitis in dairy goats, as once this disease becomes established, chronic inflammation of mammary tissues and elevated SCC will follow, resulting in reduced milk yield and quality. This publication discusses proper husbandry practices and sanitation methods that can be implemented by producers. The results of two vaccine trials as a potential means to control mastitis in ruminants are also presented and discussed. Vaccination should only be included as part of the whole herd approach to mastitis control. Any vaccination program must be carried out in conjunction with other proper management practices.

With the increased demand for “gluten-free” products in the market place, food processors and manufacturers have started to develop more and more better-tasting and nutritious food products that are also gluten-free. However, the federal food labeling regulations for gluten-free products can be very confusing for small food processors and new food product entrepreneurs. The purpose of this bulletin is to assist small food processors and food entrepreneurs in their understanding of the FDA labeling requirements for putting “gluten-free” on the label of packaged food products. The authors do not claim interpretation or replacement of any other federal or state regulations about labeling requirements.
