The objective of STC is structural protectio,n, i.e., to control termite activity within...

Rigid board insulations, including polystyrenes, polyisocyanurates and others, are used as standard building materials. In the past decade problems developed with subterranean termites entering structures, undetected, when rigid board insulation was installed as a continuous sheet beginning below gr...

Many historical sites in Italy suffer severe damages to wood structures, works of art and ancient books due to well established subterranean termite populations (Reticulitermes sp., R. lucifugus lucifugus, R. lucifugus corsicus). In six field tests, termite colonies were treated with a baiting proce...

Ants and subterranean termites are economically important insect pests in the urban environment. Managing populations of these pests through bait-toxicant control tactics is a viable option that requires a thorough understanding of their biology. The terminology used in describing a bait-toxicant co...

Using triple-mark-recapture and agonistic behavior studies one colony, consisting of 7 monitoring stations, was determined to consist of approximately 147,000 Reticulitermes foragers. This single colony was baited using Sentricon™ Termite Colony Elimination System. Sixty days later termites were abs...

A sensor comprised of a wooden monitor on which a conductive circuit of silver particle emulsion was painted was placed in a monitoring/baiting station to detect foraging activity of the subterranean termite, Coptotermes havilandi Holmgren on Little Cayman. Sensor accuracy was 100% one month after i...

Diverse plant-dervived defense compounds present an intriguing model for exploring termite responses in controlled environments. Our group is identifying terpene and sesquiterpene constituents of folded, volatile oils distilled from a variety of citrus products. These oils include the pyryl alcohols...

A weak link in the implementation of effective termite baiting techniques is reliable recruitment of termite foragers to baits. Little is known about how termites locate food sources, but many factors may influence whether foragers find and recruit to a given bait. These include the abundance and pa...

A dust containing 80% triflumuron, a chitin synthesis inhibitor, was tested for its efficacy in eradicating colonies of subterranean termites (Coptotermes spp.) in the Sydney-Newcastle area, Australia. Triflumuron is believed to act on a termite colony in the following way: first the queen stops lay...

Prevention of termite attack is preferable to remedial control. This can be accomplished through good architectural design, use of termite-resistant building materials, installation of physical or chemical barriers to prevent subterranean termite penetration, and possibly also installation of termit...

Recruit* AG is the above-ground baiting element of the Sentricon® Termite Colony Elimination System which is used to protect structures from termite infestation and damage. It is designed to be placed directly over active structural infestations of subterranean termites. Experience has shown that mu...

Some strains of the hyphomycete fungus, Metarhizium anisopliae, are highly virulent for various species of Australian termites. One of these, FI-610, has been selected for control of Coptotermes spp. and Nasutitermes exitiosus, and shown to kill mound and tree nests when sufficient dry conidia are a...

Intragallery application of 0.23% or 0.5% spinosad (suspension concentrate, SC) resulted in 98-100% drywood termite mortality in a laboratory simulated gallery bioassay and significantly reduced drywood termite activity, as measured using an acoustic emissions detector (AED), in a comparative field ...

The French Quarter of New Orleans is the site for a new national campaign against the Formosan subterranean termite, Coptotermes formosanus, an exotic species that now infests 13 states. The campaign includes the U.S. Department of Agriculture’s Agricultural Research Service, the Louisiana State Uni...

Monitoring stations of were used to observe foraging and feeding behavior of Reticulitermes at the Institute of Forest Genetics (IFG) near Placerville, and at a site in Novato. At IFG 53 monitoring stations were used by cuticular hydrocarbon phenotype A, 10 by phenotype B, and 5 by phenotype C. At N...

Structure, distribution and number of surface sensilla on the antenna of Prorhinotermes simplex (Rhinotermitidae, Isoptera) were studied by scanning (SEM) and transmission electron microscopy (TEM). Distribution and organization of sensilla on the antenna of pseudergates, presoldiers (=white soldier...

Imidacloprid belongs to a new group of insecticides, the chlorinated nicotine derivatives.

Termiticidal activity of deltamethrin as a technical and/or formulated material has been well documented around the world by governmental and university researchers in laboratory and long-term field evaluations. United States Department of Agriculture- Forest Service (USDA-FS) ”Gulfport” field testi...

Urban entomology has grown dramatically in the last 25 years and has attained a disciplinary status within the entomological and pest management community. As urban centers have grown throughout the world, the importance of the control of arthropods and insects associated with humans and their struc...

The applied objectives for bait-toxicant against subterranean termites are at minimum the suppression of foraging activity and ideally the elimination of the entire colony population. Subterranean termite colonies containing hundreds of thousands to millions of individuals may forage up to I50 m in ...

Bait toxicants were evaluated against Formosan subterranean termites infesting 61 river-bound trees in Lake Charles, Louisiana. This afforded a natural setting from which termite colonies could not escape and bait efficacy could not be misinterpreted by colony movement away from the study site. Of 1...

Determining termiticide performance has, historically, been conducted by assessing attack of wooden boards placed over treated soil. This method was developed by the USDA-FS Gulfport laboratory, and is referred to as the ground-board test. A modification of this involves pouring concrete over the tr...

Microbial (bio) insecticides are products based on living micro-organisms which are pathogenic to insects. These micro-organisms have a long history of study and are considered to have great potential as pest control agents. However. in the past research has concentrated on pests of agriculture and,...

The current world-wide status of research into urban entomology is reviewed. Data were collected by a mailed survey, and telephone or e-mail interviews. Data are incomplete, but some trends do emerge. Most research in urban entomology has an applied orientation. Personnel in most research facilities...

Anoxia resulting from contained atmospheres of ~ 0 .1 % oxygen (1,000 ppm) was lethal to all stadia of a variety of insect pests commonly encountered in museums and other sensitive areas. Low % 02 in a closed system was achieved and maintained by displacement with gaseous nitrogen. The effect of ano...

The results of a four year study with six termiticides including: bifenthrin, chlorpyrifos, cypermethrin, fenvalerate, permethrin, and isofenphos indicate significant differences in effectiveness among products applied to different soil types in Texas. Each of the five field test locations represent...

Participation at approved training seminars incurs costs and limits work availability for urban pest control company owners, supervisors, and service technicians. However, the continued need for training to properly control pests, and to acquire or renew a license forces pest control operators to co...

A population of the Formosan subterranean termite, Coptotermes formosanus Shiraki, detected in February 1992, was determined to be well established within a limited residential area of La Mesa, San Diego County, California, U.S.A. The large size of workers and soldiers, and annual swarms of reproduc...

Soil termiticide treatments provide a bamer to exclude soil-borne termites from structures. The vast populations of subterranean termites are generally unaffected by the termiticide application. In the future, monitoring, exclusion (physical or chemical bamers), and population suppression devices (b...

No choice feeding tests, Reticulitermes flavipes (Kollar) weekly survival and feeding on two bait toxicants was compared for sound sweetgum blocks and those decayed by Gloeophyllum trabeum (Pers. ex Fr.)
