Social life is usually associated with enhanced propagule pressure, which increases the chance of introducing several individuals during a single introduction event. insects are therefore among most successful invasive species, benefiting from rapid establishment and increased foundation success in new habitats. In termites, pressure may also be by development reproductive small group foraging ...

The aromatic -carboline norharmane, which is located in the fat body of Reticulitermes speratus, stimulated the activity of juvenile hormone epoxide hydrolase (JHEH) of larva, ergatoid, and nymphoid homogenates. JHEH activity of ergatoid (16.67 ± 1.30 μU/termite) and nymphoid (20.94 ± 1.64 μU/termite) homogenates fortified with 0.1 mM norharmane was significantly higher than that of ergatoid (9...

Reticulitermes flavipes (Kollar), R. virginicus Banks, and Coptotermes formosanus Shiraki were stressed by holding them at 25°C or 28°C, respectively, in metal pans for 5 d prior to introduction into 1 side of 3-jar arenas (3 containers connected serially) containing freshly­ collected nestmates. After 14 d, mass loss of wooden blocks was determined for blocks from the arena side to which stres...

The insecticidal effects of Lantana camara L. (flowers, leaves, stems and roots) and the soil where lantana had been growing, on foraging activity and survival of the subterranean termites Coptotermes formosanus and Reticulitermes flavipes were examined in a 3-week experiment. The soil in which lantana had been growing had no effect on termite tunneling and survival. Incorporation of chipped fr...

This study evaluated the natural durability of seven imported hardwoods Bangkirai (Shorea laevis), Burckella (Burckella.), Ipe (Handroanthus.), Jarrah (Eucalyptus marginata.), Kempas (Koompassia malaccensi), Malas (Homalium foetidum) and Merbau (Instia) used for deck boards against decay fungi (Fomitopsis palustris, Gloeophyllum trabeum, Trametes versicolor, Irpex lacteus) subterranean termite ...

New, and previously reported microsatellites, were characterized for a group of four cryptic sibling species in California (USA) in the subterranean termite genus Reticulitermes with the goal of finding loci appropriate for population and species level studies. Three new microsatellites were identified originating from R. hesperus, and 19 loci previously characterized in R. flavipes and R. sant...

The easy leaching of boron from wood preservation formulations has limited the use of this highly active fungicide. The recently discovered adduct with flavonoids allows boron to be retained for longer periods of time within wood and consequently to extend its life. Two different leaching treatments were compared, and the fungal and termite decay were examined. The biological tests showed extre...
