Four essential oil-based products and a liquid-based borate spray were tested for their efficacy against adult, pyrethroid-resistant, field-strain and Harold Harlan susceptible-strain bed bugs using direct spray applications. The most effective product was Green Bug (100% mortality in one hour or le...

Entomological indices based on larval surveillance methods are not sensitive enough to accurately monitor Aedes aegypti population densities in areas differing in levels of infestation. Here, we present and discuss results obtained from a pilot program using a new approach, the Monitoring System and...

Hospitals play an important role within a healthcare setting. The presence of arthropods in hospitals, like spiders, mites, bedbugs, mosquitoes, beetles, cockroaches, flies and ants, was reported in many studies. Besides its great epidemiological relevance, the presence of culicines that are potenti...

Pyriproxyfen is an insect growth regulator that affects the physiology of morphogenesis, reproduction and embryogenesis of insects. It exhibits a high level of activity against mosquito larvae inhibiting adult emergence at very low dose rates. It has low mammalian toxicity and environmental impact. ...

Outbreaks of mysterious skin lesions on multiple personnel at five military installations were initially blamed on spiders. Requests were made for pest inspection and control to remedy the situation. Pesticides were applied at four of the installations even though no medically important arthropods w...

Catches of mosquitoes and sand flies in CO2 traps baited with three different lures and an unbaited control were compared. The lures examined were carbon dioxide, carbon dioxide plus 1-octen-3-ol, and carbon dioxide plus human hair in ethanol. Studies using a 4 x 4 Latin square design, with 3 sets o...

The influence of seasonal ground temperature and relative humidity on cellulose consumption by two native subterranean termite species was evaluated in South Carolina, USA. Seven colonies of Reticulitermes flavipes Kollar and six colonies of R. virginicus (Banks) were studied. In-ground plastic buck...

SumiOne® (common name metofluthrin, 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl (E,Z) (1R,3R)-2,2dimethyl-3-(prop-1-enyl) cyclopropane carboxylate) is a novel vapor active pyrethroid that is effective against mosquitoes. Impregnated paper substrates have been shown to be effective at dispensing metofl...

Soils of pH 5, 7, and 9 were treated with the equivalent of a commercial application of 0.50% permethrin. Over a period of 36 months post-treatment, the soil was analyzed to determine the concentration in parts per million of permethrin remaining in the soil. There was a significant difference in th...

Two Navy surplus barges (each 91 x 20 ft) were equipped with one street lamp at each corner of the barge and with fourteen 60 x 80 inches white cloth panels, each panel illuminated with one 100W spotlight. Adult midge attraction to light on these barges was studied in the summer of 1998 on Lake Monr...

Chronic, unacceptable, insecticide resistant German cockroach (Elartella germanica) populations exist in some of the U.S. Army's food service facilities We have conducted field trials using heat to control German cockroaches in food service facilities. The process used involved: caulking holes in wa...

Laboratory comparisons of pyrethroid toxicities on a range of insect pests demonstrated greater kill activity than expected for the photolabile allethrin series compounds relative to other pyrethroids. Further investigation in chamber and warehouse trials confirmed the utility of S-bioallethrin in s...

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...

Commercial bait products are becoming increasingly important for household and industrial pest control. The advantages of baits are widely acknowledged and include convenience and ease of use, discrete placement of the insecticide, reduced environmental contamination and minimal disruption to the cu...

Several types of Culigel@ superabsorbent polymers were evaluated as matrices for the controlled release and/or encapsulation of insect growth regulators, bacteria, or organophosphates for long-term control of immature mosquitoes or adult and immature cockroaches. Bioassays against mosquito larvae wi...
