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...

Descriptions of Dambullaeus adonis Mąkol et Moniuszko SP NOV: (Trombidiformes: Erythraeidae, Callidosomatinae) and Latois nigrolineata Świerczewski et Stroiński SP NOV: (Hemiptera: Fulgoromorpha, Flatidae) from Madagascar are provided. The first host record for ectoparasitic larvae of Dambullaeus Haitlinger, 2001 and the first evidence on host-parasite association between flatid adult and eryth...

The unexplained collapse of honeybee (Apis mellifera) colonies across the world continues to fascinate both the scientific and mainstream media alike. This is mainly due to the worldwide importance of honeybees in ecological and commercial sectors. We recently reported how the ectoparasitic mite, Varroa destructor, altered the viral landscape in the Hawaiian archipelago by decreasing the viral ...
