Control of Reticulitermes grassei as a pest in Spain: Termite distribution in an urban area
2010 - IRG/WP 10-10719
The European subterranean termite Reticulitermes grassei Clément, 1978, has been an important pest in Palenciana, a locality in the southern province of Cordoba (Spain) for a long time. The different stages of the pest elimination process have been studied and are presented here. Firstly, a through inspection of all town dwellings was conducted in order to determine a theoretical affected area of...

Laboratory study of fipronil baits against Reticulitermes grassei (Isoptera: Rhinotermitidae)
2010 - IRG/WP 10-30553
Fipronil is currently used as chemical barrier against subterranean termites, in this paper their possible use as bait has been tested. Their efficacy with Reticulitermes grassei Clément in feed forced and feed choice tests has been analyzed, evaluating the mortality caused by administration of fipronil at 1 and 10 ppm (wt/wt). Our results show that 90% mortality is achieved at 6 days with feed f...

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...
