Termite mortalities and daily consumptions of the specimens by the termites during the 3-week-exposure are also shown in Table 5.

Termites are mainly known for damage caused to human beings, both in urban and rural areas. However, these insects play an important role in the decomposition of organic matter in tropical regions and are important natural resources, which are widely used in traditional medicine and are also consumed by human populations in several parts of the world. Prysmian Termitex Termite Resistant Power Cables Prysmian Termitex is a revolutionary cable protection system from Prysmian that provides the ultimate solution to termite attack. An effective alternative to brass taping or nylon jackets, Prysmian Termitex is a proven termite repellent which can be added to the sheathing compound of many.
Termite. Termites, sometimes known as white ants, are a group of eusocial insects usually classified at the taxonomic rank of order, Isoptera. with high resistance to wear and tear. The study. Numerous studies to date have investigated antimicrobial activity of Actinobacteria isolated from a variety of insects (Poulsen et al. , Seipke et al. , Madden et al. ), including termites (Khucharoenphaisan et al. , Matsui et al. , Visser et al. , Chouvenc et al. ) for the purpose of discovering novel by:

A number of studies on the resistance of acetylated wood to attack by wood destroying termites have been conducted, but there is no common understanding of why.
Termite" derives from the Latin and Late Latin word termes ("woodworm, white ant"), altered by the influence of Latin terere ("to rub, wear, erode") from the earlier word tarmes.
Termite nests were commonly known as terminarium or termitaria. In earlier English, termites were known as "wood ants" or "white ants".Class: Insecta. Termite mortality in blockboard specimens during termite resistance tests. Key: as for Fig.
It can be concluded from these laboratory studies that blockboard bounded by boron-treated Ekaba veneer is well protected from the brown- and white-rot Cited by: This test method covers the laboratory evaluation of treated or untreated solid wood for its resistance to subterranean termites.
This test is considered as a screening test for treated material and further evaluation by field methods is required. The leachability of these boron compounds and the termite and decay resistance of wood treated with these compounds were evaluated. The boron leaching rate of wood treated with quaternary ammonium TPB formulations ranged from to percent, while that of quaternary ammonium tetrafluoroborate formulations ranged from to percent.
Laboratory Termite Resistance Tests. Untreated and treated MDF samples were exposed to the subterranean termites, Coptotermes formosanus Shiraki, according to the JIS K standard method .An acrylic cylinder (80 mm in diameter, 60 mm in height) whose lower end was sealed with a 5 mm thick hard plaster (GC New Plastone, Dental Stone, G-C Cited by: 7.

Termite bioassay. A no-choice termite resistance test with Reticulitermes flavipes Kollar (eastern subterranean termites) was performed using five leached test specimens (25 × 25 × 6 mm) for each treatment es were collected from Janesville, WI, USA. One specimen was placed in the bottom of an acrylic cylindrical container (90 mm diameter and 60 mm height) Cited by: Comparative termite resistance of 12 Malaysian timber species in laboratory tests Roszaini Kadir School of Environment, Natural Resources Cited by: Gee Chow, a biologist who worked in Lewis' lab before forming his own termite company.

Therefore provision must be made during construction to allow space for inspection under the floor of the house. This will include the use of ant caps which aid in the detection of termites.
Laboratory studies place the barrier in direct contact with foraging subterranean termites. Resistance to damage will be evaluated. Field studies will place barriers on or in soil in areas of high termite densities.
Studies will be configured to simulate construction practices in which the barriers will be applied. 60 Further, a given material may prove resistant to one species of termite but not to 61 another (Beal et al. ; Beal and Bultman ; Watson et al. 62 Many studies on the resistance of plastics to termites were conducted under both 63 laboratory and field conditions during the s through the s (see references.

CSIRO, Australia. Division of Entomology Technical Paper No. Grace, J. () Review of recent research on the use of borates for termite. Laboratory-made particleboards were tested for their resistance to subterranean termite, Coptotermes curvignathus Holmgren (Order Isoptera, Family Termitidae) by Indonesian standard SNI –, during four weeks and at the end of the test their mass loss percentage and feeding rate were determined.
Particleboards consisted of: jabon (Anthocephalus cadamba, Cited by: 2. The book also examines caste differentiation in the three lower termite families, namely, Hodotermitidae, Kalotermitidae, and Rhinotermitidae. This volume includes discussions on the rearing, feeding, and biochemistry of termites; the radioisotopes for feeding studies; and the moisture requirements for termite Edition: 1.
Termites are of great interest to both entomologists and those concerned with pest management. On the one hand their complex social systems and nest building make them fascinating for students of insect behavior, while on the other they are major pests of crops and buildings in the tropics and subtropics.
This book provides a general scientific introduction to the termites. Earlier trials showed an improved resistance of DMDHEU-treated wood against Coptotermes formosanus and Reticulitermes speratus in a laboratory choice test (Yusuf et al. ) and in a Portuguese field trial (Schaffert et al.
). However, due to known differences in the biological behaviour, it was of interest to get information on the Cited by: test results. The results from the untreated SP control samples indicate strong termite vigor and performance, and hence the test data are valid.
