The structure of altemicidin, a new acaricidal and antitumor agent, was determined to be (1R,2S,3aR,7aS)-4-carbamoyl-2-hydroxy-6-methyl-1-(sulfamo ylacetamido)-2,3,3a,6, 7,7a-hexahydro-6-azaindene-1-carboxylic acid by a combination of spectroscopic and X-ray crystallographic analysis of its derivatives. Altemicidin is a monoterpene alkaloid.

The acaricidal effect of eleven essential oils (Sweet basil, Common juniper, Atlas cedar, Coriander, Blue gum, European silver fir, Common lavender, Lemon, Peppermint, Scots pine, Summer savory) against poultry red mite Dermanyssus gallinae was tested in vitro using the direct contact method, at three different doses: 0.2 mg/cm2, 0.4 mg/cm2 and 0.6 mg/cm2. The results of the study revealed that...

Acaricidal resistance studies were carried out Department of Veterinary Parasitology in Udaipur to detect status against commonly used commercial acaricides, 1.25% Butox® (Deltamethrin) and 10% w/v DERMEEZ® (Cypermethrin) ticks collected from three villages (Vallabhnagar, Ranchorpura Kikawas) Udaipur, Rajasthan using Adult Immersion test (AIT) Larval packet (LPT). Recommended concentration acar...

Milbemycins are a family of sixteen-membered macrolides produced by Streptomyces hygroscopicus subsp. aureolacrimosus. They exhibit broadspectrum insecticidal and acaricidal activity. * ~ 3) In the course of our studies on the microbial conversion of milbemycins, we obtained 13/?hydroxymilbemycins A3 (2b), A4 (lb), and D (3b) from milbemycins A3 (2a), A4 (la), and D (3a), respectively, and 1 3j...

Tetranychus cinnabarinus is an important agricultural pest with a broad host range. We previously identified curcumin as a promising acaricidal compound against T. cinnabarinus. However, the acaricidal mechanism of curcumin remains unknown. In this study, RNA-seq was employed to analyze the transcriptome changes in T. cinnabarinus treated with curcumin or the solvent. A total of 105,706,297 cle...

OBJECTIVE To examine the acaricidal effects of the essential oil of Cymbopogon citratus leaf extract (lemongrass) and ethanolic Azadirachta indica leaf extract (neem) against house dust mites Dermatophagoides farinae (D. farinae) and Dermatophagoides pteronyssinus (D. pteronyssinus). METHODS Twenty-five adults mites were placed onto treated filter paper that is soaked with plant extract and b...

The number of studies emphasizing the possible damage that acaricidal spray formulations can cause on engorged female ticks’ reproductive parameters is small. The present study evaluated the deleterious effects of a spray formulation (dichlorvos 60% + chlorpyrifos 20%) on the reproductive parameters of a susceptible population of Rhipicephalus (B.) microplus females, using the Stall Test. The t...

Here we describe a rare clinical manifestation of canine pododemodicosis. A dog was presented with pedal erythema, scaling, crusting, severe edema and digit loss. The following diseases were taken into account for the differential diagnosis: pododemodicosis, lethal acrodermatitis, zinc responsive dermatosis and pemphigus foliaceus. Results from skin biopsies revealed the presence of Demodex spp...
