Laboratory evaluation of four benzoylphenylureas against two species of Reticulitermes Holmgren, 1913 (Isoptera: Rhinotermitidae) from Southwest Europe
2008 - IRG/WP 08-30472
The use of benzoylphenylureas in baits for the control of termite pest is currently increasing. The chemical compounds used have been tested mainly with American termites. The effectivity against non-American termite species must be analyzed because the worldwide use of those compounds. In this paper four benzoylphenylureas (hexaflumuron, diflubenzuron, triflumuron and noviflumuron) have been test...

2009 - IRG/WP 09-20407
Drywood termites (Isoptera: Kalotermitidae) are serious economic pests of both plants and seasoned wood (furniture, wood frame structures). Currently, five species of kalotermitids are known to occur in the Hawaiian Islands: Neotermes connexus, Incisitermes immigrans, Incisitermes minor, Cryptotermes brevis, and Cryptotermes cynocephalis. These termites are difficult to detect and observe due to ...

Termite taxonomy and distribution with particular reference to climate change in Africa
2010 - IRG/WP 10-10738
Termites constitute an integral component of various ecosystems in Africa. Termites are also amongst the most difficult of the insects to study because of their cryptic behaviour. There are around 2600 species of termites (Isoptera) in 280 genera which have been described worldwide and about 39% of the total termite species are found in Africa. Some termite species are well known pests of agricul...

Phytosanitary standards and the potential for acceptance of chemical treatments as a phytosanitary measure
2011 - IRG/WP 11-30558
Regulations governing international trade in forest products must balance the economic and social benefits of trade with the potential risks of transporting invasive species. The International Plant Protection Convention (IPPC) is an international agreement intended to manage this process. It develops international phytosanitary standards (ISPMs) that are recognised by the World Trade Organisation...

ISPM No. 15 and the Incidence of Wood Pests: Recent Findings, Policy Changes, and Current Knowledge Gaps
2011 - IRG/WP 11-30568
Largely as a result of international trade, hundreds of species of bark- and wood-infesting insects have become established in countries outside their native range. Many of these exotic insects have caused severe economic and environmental impact to urban and forest trees in the receiving countries. Most bark- and wood-infesting insects have been transported to new countries by means of the wood...

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...

Transfer of thiamethoxam from exposed to non-exposed workers of Microcerotermes diversus Silvestri (Isoptera: Termitidae)
2012 - IRG/WP 12-10783
Because Microcerotermes diversus (Silvestri), a subterranean termite, is able to attack cellulosic materials, it is destructive to structures and the most economically important wood pest in Iran. Therefore, control or management of the termite is a serious public concern. The use of nonrepellent termiticides such as thiamethoxam (a neonicotinoid compound) has been gaining popularity in recent yea...

Effect of Rifampin on gut symbiotic bacteria isolated from Anacanthotermes vagans Hagen (Isoptera: Hodotermitidae)
2014 - IRG 14-10835
Termites thrive in terrestrial ecosystems and play an important role in bio-recycling of the lignocellulosic biomass, that is a mixture of cellulose, hemicellulose and lignin. However, these insects become pests when they interfere with human interests related to wood/cellulose products, attacking structural timber, furniture and paper products. Sustainable management of subterranean termites usin...

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...

Pest and pathogens threaten the sustainability of plantation forestry: Global research collaboration will define the future
2018 - IRG/WP 18-50341
Global plantation forestry is dominated by intensively managed stands of Pinus, Populus, Acacia and Eucalyptus species. The greater proportion of these plantations has been established in areas where the trees are non-native and have thus been separated from their natural enemies. In all documented cases, these plantations have initially been free of serious pest and disease problems. But as ti...

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...
