Background & Aim: Tetranychus urticae Koch is one of the most important pests of crops, ornamental and greenhouse plants in the world and, can damage to 900 plant species. Resistances to pesticides and acaricides have guided researches to introduce new methods to control T. urticae. Botanical pesticides are an important group of natural productions that are usually safer than ...

Exposure of the skin to ultraviolet (UV) radiation, particularly its UV-B component (280-320 nm), from the sun results in erythema, edema, hyperplasia, hyperpigmentation, sunburn cells, immunosuppression, photoaging, and skin cancer. Amongst these various adverse effects of UV-B radiation, skin cancer and photoaging are of great concern. More recent changes in lifestyle have led to a significan...

The Cosmetic Ingredient Review Expert Panel (Panel) has issued an amended safety assessment of 7 Hypericum perforatum-derived ingredients as used in cosmetics. A common name for this plant is St John wort. These ingredients function in cosmetics as skin-conditioning agents-miscellaneous and antimicrobial agents. The Panel reviewed relevant animal and human data related to the H perforatum-deriv...

A growing era of alternative medicine is upon us. All who practice medicine have a small population of patients who eschew Western medicine and prefer alternative approaches, including botanical remedies, to treat their medical problems. Many alternative practitioners advertise and sell products on the Internet. Indeed, this trend now includes a growing number of topical treatments for skin can...

Propolis is a resinous substance collected by bees (Apis mellifera) from various tree buds which they then use to coat hive parts and to seal cracks and crevices in the hive. Propolis, a known ancient folk medicine, has been extensively used in diet to improve health and to prevent disease. In the present study, we have evaluated the effects of ethanolic extracts of Brazilian propolis group l2 ...

Milbemycins are a family of sixteen-membered macrolides produced by Streptomyces hygroscopicus subsp. aureolacrimosus. They exhibit broad-spectrum insecticidal and acaricidal activity. * ~ 3) In the course of our studies on the microbial conversion of milbemycins, we obtained 13/?hydroxymilbemycins A4, A3, D, 13/Miydroxy-LLF28249a, 28-hydroxymilbemycin D, and 28-hydroxy-LL-F28249a by using Cunn...

The carmine spider mite, Tetranychus cinnabarinus (Boisduval), is an economically important agricultural pest that is difficult to prevent and control. Scopoletin is a botanical coumarin derivative that targets Ca2+-ATPase to exert a strong acaricidal effect on carmine spider mites. In this study, the full-length cDNA sequence of a plasma membrane Ca2+-ATPase 1 gene (TcPMCA1) was cloned. The se...
