Assessing physical barrier on the basis of a laboratory test is an important step on the product development, as those barriers have to remain efficient towards subterranean termites as long as the building is in service. This becomes more challenging when the anti-termite barrier has to resist agai...

Cyantraniliprole is a novel insecticide that belongs to the anthranilic diamide class of insecticides. The novel mode of action of cyantraniliprole depletes calcium from insect muscle, affecting muscle contraction, causing paralysis and eventually death. We report the results of testing of two formu...

In the past years test systems for the evaluation of repellents, attractants and insecticides/acaricides have been developed and further refined in our laboratory. A standardized laboratory test system for the evaluation of tick repellents (Moving-Object (MO) Bioassay) has been extensively used with...

The species of termites that have an impact on urban dwellings in Southeast Asia are reviewed. Termites of the genus Coptotermes are considered, by far, to have the greatest economic impact on urban dwellings. In Peninsular Malaysia, where the species of Coptotermes have been relatively well studied...

Insecticide resistance in insects is a well-documented phenomenon that is equally related to toxicology and evolutionary biology. Insecticide resistance in the German cockroach has a long history dating back over 60 years. Thus, the recent evolution of gel bait aversion resistance is but one example...

Although there are few cockroaches in newly built or insecticide-treated buildings or houses, they enter from outside, increase in number and spread out widely as time goes by. To elucidate how German cockroaches distribute widely in such places, we previously investigated their horizontal movement ...

This descriptive survey studied comparison of malaria cases, epidemiological and entomological serves, insecticides used and mean temperature, relative humidity and amounts of rain fall in a ten year period (1994-2003).The most important species of anopheline vectors include: Anopheles stephensi, An...

Termites are considered to be urban pests in Japan, which has a long history of combating the two most economically important subterranean termites [Reticulitermes speratus (Kolbe) and Coptotermes formosanus Shiraki], since Japanese houses are made principally of wood. Approximately half of new home...

A brief overview on the options for biological control of termites is presented. Many organisms have been identified as being able to kill termites. However, we do not know their real impact on field populations of termites. Research has focused on some entomopathogenic nematodes and the fungi Beauv...

Eliminating termites from structures is a real-world battle that requires vigilance, knowhow, and the best tools available. Chlorfenapyr, the active ingredient in MYTHIC®, STEALTH®, and PHANTOM®, is unique among termiticides and belongs to a class of chemistry called “pyrroles”. Chlorfenapyr is non-...

Residual performance of a pyrethroid/chitin synthesis inhibitor (alpha-cypermethrin/flufenoxuron) suspension concentrate formulation on plywood panels against German cockroaches was examined in the laboratory for up to 6 months of aging using three evaluation methods (forced-contact, self-contact an...

House dust mites are one of the main reasons for allergies which makes an efficient control necessary. The commonly used compounds are pyrethrins, pyrethroids but also compounds as benzyl benzoate. Furthermore the acaricidal effects of some solvents (e.g. propylenglycol, diethylenglycolmonobutylethe...

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...

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,...

Pest control in urban environment can be carried out either sporadically or in a concentrated way, covering large areas. The efficacy of organized pest control programs comprising large parts of cities or even whole cities is far higher than the success of separate control works done by individual m...

When parent adults were kept and allowed to oviposit at 20'C in a long day (14L:lOD) regime, and the eggs and hatching larvae were reared at 20°C under the same conditions or in darkness, no or very few (less than 12%) fully-grown larvae entered diapause. When parent adults were kept and allowed to ...
