Biology and Management of the Bermudagrass Mite, Eriophyes cynodoniensis

Characteristic tufting damage wrought by Bermudagrass mites to ‘Celebration’ bermudagrass shoots in a heavily infested golf course fairway.

The bermudagrass mite, Eriophyes cynodoniensis (Sayed) (Arthropoda: Arachnida: Eriophyidae), also known as the couch grass mite, can be a serious pest of bermudagrass in multiple high-maintenance turf systems such as sod production, athletic fields, and golf courses. Mites cause leaf and bud galls, which can lead to severe aesthetic damage and plant decline or death in high-maintenance areas with low tolerance for plant damage. In this 7-page fact sheet written by Pablo Agustin Boeri, Nicole D. Benda, J. Bryan Unruh, and Adam Dale and published by the UF/IFAs Entomology and Nematology Department, review the biology, identification, and management of the bermudagrass mite, and get specific management recommendations based on evidence from UF/IFAS research.

Stinging and Venomous Caterpillars of the Southeast

io moth caterpillar Automeris io

Wasp and bee stings are familiar to most people, but some might be surprised to learn that several caterpillars can also sting. Unlike wasps and bees with stingers, these caterpillars have barbed hairs that break off the caterpillar when it brushes against something. The hairs embed in skin and cause sudden or gradually building pain. The severity of a caterpillar sting varies based on the person and number of spines in the skin. Many stinging caterpillars also release a toxin on contact, which may cause health problems for some people. This 4-page fact sheet written by Rebecca Perry and Adam Dale and published by the UF/IFAS Department of Entomology and Nematology describes several stinging caterpillars commonly found throughout the southeastern United States.

Managing Southern Chinch Bug in Warm Season Turfgrasses

Figure 1. Southern chinch bug, Blissus insularis Barber. From left to right: nymph, short-wing, and long-wing adults

Southern chinch bug, Blissus insularis Barber, is the most damaging insect pest of St. Augustinegrass in the United States. St. Augustinegrass is the most common turfgrass used in Florida. The ubiquity of this single turfgrass species makes southern chinch bug an economically important pest in the state. In fact, chinch bugs cost Florida homeowners and professionals millions of dollars every year. This 7-page fact sheet written by Eileen A. Buss, Brianna M. Whitman, and Adam G. Dale and published by the UF/IFAS Department of Entomology and Nematology describes the biology of the pest and the damage it causes and lists ways to scout and monitor for chinch bugs and some strategies for control of the pest.
