Monthly visits to 2 field sites in southern Mississippi were made to determine the influence of monitor examination on feeding site affinity by southeastern native subterranean termites (Reticulitermes spp.). Wooden board monitors were examined once every 30, 60, or 90 days. Presence of live termites and damage to the boards (both binary parameters) were collected for each plot examined over a ...
microcerotermes diversus silvestri (isoptera: termitidae) is the most economically destructive wood pest in structures in khuzestan province (iran). chemicals such as essential oils and plant extracts that are compatible with the environment and have high potential to be used in integrated pest management programs are extremely important resources. this study evaluated contact and digestive tox...
Enviton. Entomol. 11: 1290-1293 (1982) A census of 24 1-ha plots indicated .an average abundance per ha of 4.42 colonies of Reticulitermes flavipes (Kollar) and 2.38 colonies of R. virginicus (Banks). Nearest neighbor analysis indicated the mean distance between colonies of R. f2avipes to be 22.48 m, between colonies of R. virginicus to be 26.19 m, and between colonies, irrespective of species,...
Termites have a great potential to cause damage plants and other woody materials because these insects live in colonies. Termites' preferences for harm vary depending on the species. Surveys related termite species, estimates of that occurred, as well trees attacked Riau Islamic University Area were carried out an initial step avoid impact greater attack. The survey results showed termites foun...
Historic background and the concept of slow-acting toxicants for population suppression of subterranean termites are reviewed. Information needed for development of bait-toxicants and studies needed to generate such informa tion are summarized. Current control measures for subter ranean termites rely exclusively on soil termiticides, primarily organophosphates and pyrethroids. They are used a...
Baiting techniques have been developed over the years to control Coptotermes species, the most economically important termite species in Australia. Given the restrictions on organochlorines as termiticides in North America, this paper highlights research that has focussed on baiting programs against Coptotermes as alternatives to current control measures: drenching soil with pesticides or fumig...
