Cockroaches are of the great importance in public health. Blattella germanica is the main specie that infests commercial kitchens and industrial kitchens, due to conditions for their development. One of the methods to control B. germanica is the use of insecticides in the gel bait formulation. The o...

Flies control is still a complex problem in many systems but particularly in animal husbandry. An unstructured approach remains towards them in the various affected activities, which still too often are activated only in the face of an emergency. Even in modern farms, IPM for flies is not considered...

Albino mice were single caged and offered a chloralose formulation in a standard ‘...

Urban centres amplify both abiotic and biotic parameters favouring pest life history. In absence of natural enemies in urban areas, these parameters often are directly proportional to growth and population of these pests. Under the influence of climate change and global warming, these centres will a...

Mosquitoes transmitting infectious disease have a diversity of habitats in Nagano, and many species can be expected. There have been few reports about mosqu...

Thermal control is one of the possible control methods for bedbug infestations. It is however often assessed controversially. This assessment is not always based on objective arguments and rarely on own, practical experiences. On the basis of practical trials and experiences from over 450 heat treat...

Inside a two year old family house, clothes moth adults appeared in all rooms in 2012. Inspection of clothes did not find any moths. The moth population was heavy, with at least 10 moths caught daily. Thermal fogging inside the house with deltamethrin reduced flying moths for no more than 14 days. T...
