Rice (Oryza sativa) is susceptible to damage during storage including quantity and quality. for a long time will experience decrease in quality both chemically physically. This study was aims determine the chemical physical properties of rice attacked by lice (Sitophyllus oryzae sp). The experiment arranged Randomized Completely Block Design (RCBD) with treatments form samples commercial rice, ...

It is generally thought that the evolution of obligate parasites should be linked intimately to the evolution of their hosts and that speciation by the hosts should cause speciation of their parasites. The penguins and their chewing lice present a rare opportunity to examine codivergence between a complete host order and its parasitic lice. We estimated a phylogeny for all 15 species of lice pa...

This study was carried out on two long-legged buzzards that were brought for treatment to the surgery clinic of the Veterinary Faculty, University of Selçuk. A few lice were observed on the body surfaces of the birds. Forty-seven lice were collected from the buzzards. The lice were preserved in a tube containing 70% ethanol. They were mounted on slides separately after being cleared in lactophe...

netic analysis of lice supports direct contact between modern and archaic humans. et al. Molecular identifi cation of lice from pre-Columbian mummies. al. First molecular evidence of Bartonella quintana in Pediculus humanus capitis (Phthiraptera: Pediculidae), collected from Nepalese children. et al. Genotyping of human lice suggests multiple emergencies of body lice from local head louse popul...

We examined Swainson's warblers (Limnothlypis swainsonii (Audubon, 1834), Aves: Parulidae) for lice fauna during 2 yr at three study sites in Arkansas, USA. A total of 66 individuals were examined; eight birds (10.6%) were parasitized with 16 lice of two new species belonging to two genera Myrsidea Waterson, 1915 (Amblycera: Menoponidae) and Brueelia Kéler, 1936 (Ischnocera: Philopteridae). Par...

The insecticidal activity of spinosad was evaluated against susceptible and permethrin-resistant human lice. In a permethrin-susceptible strain of the body louse, Pediculus humanus humanus L. (Anoplura: Pediculidae), the toxicity of spinosad was similar to that established for permethrin, with an LD50 value of 1.2 ng/insect and 2.4 ng/insect, respectively. Topical application of spinosad to pop...

We report detection of Bartonella quintana Brenner, the pathogenic agent of trench fever, from body lice, Pediculus humanus L., infesting homeless people in Tokyo by polymerase chain reaction. Two of 12 (16.7%) homeless were infested with Bartonella-positive body lice. From the current status of the recent increase of homeless people in many large cities of the developed countries, a medical ex...

Preening is the principle behavioral defense used by birds to combat ectoparasites. Most birds have a small overhang at the tip of their bills that is used to shear through the tough cuticle of ectoparasitic arthropods, making preening much more efficient. Birds may also scratch with their feet to defend against ectoparasites. This is particularly important for removing ectoparasites on the hea...
