Preliminary laboratory bioassay to evaluate engineered Fibre-boards against subterranean termites C. acinaciformis (Isoptera: Rhinotermitidae)
2012 - IRG/WP 12-10768
In Australia, laboratory bioassays with subterranean termites typically contain groups of workers and soldiers in a substrate of moist mound material. This termite substrate may affect termite consumption, and the test materials create a favorable termite condition for the test. The main purpose of this test is to examine the effect of a melamine formaldehyde treatment of wood panels to evaluate t...

Laboratory and Field evaluation on Natural Resistance and Feeding Preference of Different Wood Species to Subterranean Termites (Isoptera: Rhinotermitidae, Termitidae) in Pakistan
2012 - IRG/WP 12-10769
The resistance of twenty four different woods to attack and damage by subterranean termite species Heterotermes indicola (Wasmann) and Coptotermes heimi (Wasmann) was evaluated by choice and no choic in laboratory and field trials. Mean wood mass loss was calculated for both laboratory and field trials results using Analysis of Variance (ANOVA). Mean percentage termite mortality was calculated fo...

The importance of proper taxonomic identification, a case study with Reticulitermes spp. from USA
2012 - IRG/WP 12-10774
Taxonomy has been evolving with recent advancement in molecular and internet technologies. The importance of a stable taxonomic foundation is unquestionable as this science provides crucial information about evolutionary relationships and allows questions about the life history and ecology of organisms to be asked. We hope to highlight the issues and lessons we have learned from revising the taxon...

Bioavailability of Bifenthrin and Fipronil against subterranean termites (Isoptera: Rhinotermitidae) in various soils
2013 - IRG/WP 13-10804
Present study was conducted to determine the toxicity and bioavailability of Biflex (Bifenthrin) and Fipronil (Phenyl pyrazole) termiticides against common termite species Heterotermes indicola (wasmann). Soil was collected from ten different areas of Lahore and was divided into sandy clay loamy (SLC) soil and sandy loamy (SL) soil after analysis. Laboratory bioassays (Topical application method a...

Toxic effect of Melia azedarach L. unripe fruit extracts onto Reticulitermes flavipes Kollar (Isoptera: Rhinotermitidae)
2015 - IRG/WP 15-10848
The subterranean termite, Reticulitermes flavipes Kollar (Isoptera: Rhinotermitidae), is part of one the major biotic agents which damage wood and it is a pest in several countries, where the economic losses are huge. In Chile there have been foci of infestation in the Metropolitan Region and in the Region of Valparaíso with a big expansion in the last years. This study evaluated in laboratory th...

Repellency of Schinus molle L. leaf extracts onto Reticulitermes flavipes Kollar (Isoptera: Rhinotermitidae)
2015 - IRG/WP 15-10850
Reticulitermes flavipes Kollar (Isoptera: Rhinotermitidae), is a subterranean termite which damage wood and it is a pest in several countries, where the economic losses are huge. In Chile there have been foci of infestation in the Metropolitan Region and in the Region of Valparaíso with a big expansion in the last years. This study evaluated in laboratory the repellence effect of extracts from Sc...

New approach to improve the estimation of colony population in subterranean termites (Blattodea: Rhinotermitidae)
2016 - IRG/WP 16-10866
The aim of this study was to estimate the mortality and fading effects of dye markers Neutral red and Nile blue commonly used in the estimation of termite colony population, in order to determine the decrease rate from the initial number of marked and released termites. This rate can be considered in the application of the different indexes used to calculate the number of termites of the colony. I...

Evaluation of the effects of different concentrations of Fipronil against Reticulitermes grassei (Blattodea: Rhinotermitidae)
2016 - IRG/WP 16-30702
A laboratory evaluation of the effect of different concentrations of Termidor (fipronil at 9.09%) has been carried out. Six concentrations (10,000; 1,000; 100; 50; 10 and 5 ppm) have been tested in two different colony models imitating an open environment.
After five days treatment, mortality data were collected. The three higher concentrations showed nearly 100% mortality. At 50 ppm the mortalit...

Analysis of hindgut bacterial phyla frequency and diversity in subterranean termites exposed to chitosan-treated wood
2017 - IRG/WP 17-10882
The termite hindgut contains a microbial community that symbiotically aids in digestion of lignocellulosic materials. For better understanding of the dynamics of the bacteria-termite relationship, a species survey of bacterial hindgut microbes in subterranean termites (Reticulitermes flavipes: Kollar) collected from Louisville, Mississippi was performed after exposure to chitosan-treated and contr...

Effects of teak, Tectona grandis Linn, heartwood extractives against Heterotermes indicola (Isoptera; Rhinotermitidae)
2018 - IRG/WP 18-10910
Heartwood extractives from Tectona grandis were investigated for antitermitic activities against Heterotermes indicola in laboratory experiments. Extractives were removed from wood shavings by soxhlet extraction using an ethanol: toluene (2:1) solvent system. Termite feeding and mortality followed a concentration dependent response. The highest termite mortality occurred at an extractive concentra...

Control of Asian subterranean termites Coptotermes gestroi (Blattodae: Rhinotermitidae) by a new generation bait system with vegetal extracts-diflubenzuron mixture
2023 - IRG/WP 23-30797
The efficacy of anti-termite bait pebble dosed at 0.3% w/w of Diflubenzuron, and Chitin Synthesis Inhibitor (CSI) and 0.6% w/w of vegetal extract from Berkem Biosolutions®, was evaluated in the laboratory on the Asian subterranean termite Coptotermes gestroi (Wasmann). Four concentrations 33.3%, 50%, 50% bis and 100% as well as two neutral matrices, were used in two in-house developed test method...

Laboratory evaluation of PA1b, an insecticidal protein extracted from pea seeds (Pisum sativum), as bait active ingredient against the subterranean termite Coptotermes gestroi (Blattodea: Rhinotermitidae) in tropical zones
2024 - IRG/WP 24-11038
Coptotermes gestroi (Wassman 1896) is one of the worst pests in tropic areas, economically. Two types of curative methods are used since decades to eliminate colonies that attack constructions: injection of biocidal treatment solutions on wood, walls and soil, and population control using baits. In application of the current regulations, the first technique can no longer be used in Europe, to lim...
