Subterranean termites in the genus Coptotermes Holmgren are structural pests that have become globally distributed beyond their native range in Southeast Asia. Because of their destructive nature, it is useful to understand the pathways of their spread. Additionally, phylogenetic analysis of evolutionary relationships may lead to increased accuracy of insecticide-based management on the basis t...

We report myiasis by Lucilia silvarum with an overall prevalence of 0.9% in amphibian populations in boreal Alberta. In the period 1998--1999, we documented L. silvarum infestations in wild populations of wood frog (Rana sylvatica), boreal chorus frog (Pseudacris maculata), boreal toad (Bufo boreas boreas), and Canadian toad (B. hemiophrys). We believe this is the first record of this parasite ...

Spatio-temporal distribution of Coelaenomenodera lameensis Berti and Mariau, 1999, pest of palm oil tree (Elaeis guineensis Jacquin, 1963) was carried out on 1226 ha of an industrial plantation at Toumanguié (south-east of Côte d’Ivoire). Temporal distribution of population established the existence, according to the years, of favorable periods of Coelaenomenodera lameensis infestations. Eight ...

The efficacy of a flumethrin 1% pour-on (Bayticol, Bayer AH) was evaluated against natural infestations of ticks on cattle on a dairy farm in Ethiopia during 1997/98. The cattle, (n = 92), which were Friesian/ Zebu crosses, were heavily infested with Boophilus decoloratus. Dry cows (n = 8) were randomly selected and allocated either into a treatment or a control group. Flumethrin 1 % pour-on wa...

Health burdens associated with poor housing and indoor pest infestations are likely to affect young children in particular, who spend most of their time indoors at home. We completed environmental assessments in 644 homes of pregnant Latina women and their children living in the Salinas Valley, California. High residential densities were common, with 39% of homes housing > 1.5 persons per room....

Monitoring programs increasingly are used to document the spread of invasive species in the hope of detecting and eradicating low-density infestations before they become established. However, interobserver variation in the detection and correct identification of low-density populations of invasive species remains largely unexplored. In this study, we compare the abilities of volunteer and exper...

The most important ectoparasites infesting/infecting alpaca (Vicugna pacos) and llama (Lama glama) are reviewed. The clinical manifestation and the diagnosis of the different parasitic infections/infestations of Sarcoptes scabiei, Chorioptes sp., Psoroptes sp., Damalinia (Bovicola) breviceps and Microthoracius spp. are described as well as therapies against them. Demonstrating S. scabiei and Ch...

Proteins extracted from salivary glands of unfed, three days and five days fed adult Hyalomma marginatum marginatum were analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). We have noticed changes during the three feeding steps. Some proteins disappeared during feeding process (23, 38, 39, 40 to 50, 95 and 112 kDa), they might be proteins which were converted in ot...
