Microcapsule formulation of fenitrothion as a soil termiticide
1991 - IRG/WP 1478
The efficacy and the mode of action of a microcapsule formulation of fenitrothion against Coptotermes formosanus Shiraki were investigated. The physicochemical property that this formulation does not allow the active ingredient to diffuse through the capsule wall contributed to a long lasting efficacy and safety for the men spraying. The residual effect of the fenitrothion microcapsule in soil was...

Testing of termiticides in soil by a new laboratory method with regard to Phoxim for replacement of chlorinated hydrocarbons
1986 - IRG/WP 1292
In comparison to chlorinated hydrocarbons insecticides of the compound classes organophosphates, carbamates and pyrethroids were tested according to an earlier described soil-test in the laboratory. The following termite-species were used: Heterotermes indicola, Reticulitermes santonensis and in addition Reticulitermes flavipes, Reticulitermes lucifugus, Reticulitermes speratus and Coptotermes for...

Resistance to soft rot of hardwood plywood treated with CCA salt
1983 - IRG/WP 3258
Plywood made from indigenous hardwoods was treated at an average loading of 34 kg Celcure A per m³ and was installed in a field test. After 20 years the samples were only slightly attacked by soft rot and the glue bonds were still intact....

Termiticidal effectiveness of synthetic pyrethroids, carbaryl and chlordane in wood-block test
1985 - IRG/WP 3356
The results of some wood-block tests with allethrin, permethrin, fenvalerate, carbaryl and chlordane against Coptotermes formosanus are tabled and compared against some organophosphates, chlorpyrifos, fenitrothion, phoxim, tetrachlorvinphos and acephate. The treatment of the wood blocks was exactly as described in Document No: IRG/WP/3330. Among the pyrethroids tested, permethrin was the most effe...

Tunneling ability of subterranean termites through termiticide-treated soil
1988 - IRG/WP 1375
A test apparatus was designed to facilitate accurate measurement of termite penetration into termiticide-treated soil; three termiticides at 500 ppm were evaluated. Coptotermes formosanus Shiraki workers tunneled significantly farther into chlordane-treated soil than did Reticulitermes flavipes (Kollar). Both species only slightly penetrated chlorpyrifos-treated soil. Neither species penetrated so...

Evaluation of termiticides in field trials
1990 - IRG/WP 3633
Termiticide-treated posts and stakes have been tested at the field test site in Kagoshima, Southern Kyushu, Japan. Various commercial and alternative termiticides have been evaluated annually as TAI (termite attack index), calculated by the equation: TAI = R x P, where R is the mean of attack rating of 0 (sound), 10 (sign of tasting), 30 (slight attack), 50 (moderate attack), 100 (severe attack), ...

The preventive actions of three commercial wood preservatives against Dinoderus minutus
1984 - IRG/WP 1233
Dinoderus minutus is one of the most common pest insects for the bamboos. For preventing the damages of this insect, the preventive treatment of bamboos with preservatives is necessary. But because of the environmental reasons, only limited insecticides are available in Japan. The author determined the preventive effects of three commercial products against Dinoderus minutus by the medium of the B...

Laboratory tests on the residual effects of pyrethroids against termites after one year
1983 - IRG/WP 1216
Due to recent restrictions of ecological nature which most of pesticides are been submitted, it is necessary in wood preservation to test new products and formulation with low mamalian toxicity for substitution of the traditional products. The efficiency of five synthetic pyrethroids in comparison to the traditional organo-chlorinated pesticide chlordane was evaluated. Wood blocks impregnated with...

Laboratory evaluation of six commercial termiticides against subterranean termite, Coptotermes gestroi Wasmann
1994 - IRG/WP 94-30034
Small specimens of Heavea brasiliensis (10 x 10 x 20 mm³) were exposed to the laboratory colony of Coptotermes gestroi Wasmann for 4 months after dip- or brush-treatment with six commercially available emulsifiable termiticides (alpha-cypermethrin, cypermethrin, permethrin, bifenthrin, chlorpyrifos and chlordane). Synthetic pyrethroids and chlorpyrifos were effective as well as 1% treatment of ch...

Soil termiticides: A review of efficacy data from field tests
1987 - IRG/WP 1323
This paper reports efficacy data from the field evaluation of various soil termiticides by the U.S. Department of Agriculture, Forest Service, Gulfport, Mississippi. These chemicals, which include a number of chlorinated hydrocarbon, organophosphate, pyrethroid, and carbamate insecticides in a range of concentrations, have been in long-term tests at seven field sites. Data are reported for the gro...

Variable chlordane residues in soil surrounding houses in Louisiana
1989 - IRG/WP 1404
Eight soil samples from each of 30 houses in greater New Orleans, Louisiana were collected in October, 1986 and analyzed for chlordane residues (ppm). All houses had reportedly been treated in the late 1960's or early 1970's. Chlordane occurred in all samples, and the overall mean (+ SEM) was 870.6 + 96.5 ppm. Residue levels were unaffected by construction type (slab, crawl, craw...

Laboratory tests on the residual effects of pyrethroids against termites thirteen years after application
1994 - IRG/WP 94-30056
This paper is in continuation to a series of articles published on the work being developed in Brazil regarding the feasibility of using photostabl synthetic pyrethroids against termites. Tests were carried out to compare the efficacy of five synthetic pyrethroids with the traditional organo-chlorinated pesticide, chlordane. Wooden blocks were impregnated with alcohol-based solutions of the above-...
