Biological control studies of soft and hard ticks in Egypt
TLDR
Three varieties of Bacillus thuringiensis were investigated against the soft tick Argas persicus and the hard tick Hyalomma dromedarii and Concentrations lethal to 50% of tick populations indicated that Dipel 2x was the most potent, followed by Vectobac and HD 703.
Light and electron microscopic studies of Myxobolus stomum n. sp. (Myxosporea: Myxobolidae) infecting the blackspotted grunt Plectorhynicus gaterinus (Forsskal, 1775) in the Red Sea, Egypt
TLDR
The ultrastructure of the plasmodial wall and sporogenesis of the present species followed the usual pattern valid for most studied myxosporean species.
Studies on monieziasis of sheep I. Prevalence and antihelminthic effects of some plant extracts, a light and electron microscopic study
TLDR
Treatment of heavily infected animals showed an antihelminthic effect, since the complete absence of eggs was recorded 9 days after treatment when fecal investigations were done, and in vitro results indicated that the plant extract is efficacious at all concentrations tested.
The efficacy of neem seed extracts (Tre-san®, MiteStop®) on a broad spectrum of pests and parasites
TLDR
Tests on skin compatibility proved that there are no skin irritations during or after use, however, some target species are less sensible (beetles, Triatoma stages, fly maggots), while the specimens of the other species cited above were successfully killed even at low concentrations of the extract.
Some species of the genus Myxobolus (Myxozoa: Myxosporea) infecting freshwater fish of the River Nile, Egypt, and the impact on their hosts
Abstract. Six Myxobolus species are described from Nile fish, five of which are new and one is redescribed: M. naffari Abdel Ghaffar et al., 1998 was recovered from the gills of Labeo niloticus and
Morphological and molecular biological characterization of Pleistophora aegyptiaca sp. nov. infecting the Red Sea fish Saurida tumbil
TLDR
Comparison of the nucleotide sequences and divergence showed that the sequence of the present microsporidium was most similar to that of Pleistophora anguillarum (99.8% identity) differing in 13 nucleotide positions, so the present species was recorded and phylogenetically positioned as a new species of Pleistsophora.
Why is it crucial to test anti-lice repellents?
TLDR
There are much more difficulties to repel lice when compared to other insects or even ticks; it must be feared that several repellents on the market might have used a problematical test system and thus might not be as effective as they claim.
Life cycle and attacks of ectoparasites on ruminants during the year in Central Europe: recommendations for treatment with insecticides (e.g., Butox®)
The occurrence of ectoparasites on ruminants throughout the yearly seasons was compiled from the literature and from our own experiments that were based on ultraviolet trap catches during the years
Efficacy of a single treatment of head lice with a neem seed extract: an in vivo and in vitro study on nits and motile stages
TLDR
An anti-louse shampoo (Licener®) based on a neem seed extract was tested in vivo and in vitro on its efficacy to eliminate head louse infestation by a single treatment and found that a total submersion for only 3 min prior to washing 3× for 2 min with tap water was sufficient to kill all motile stages.
