To repel mosquitoes, there have been many highly effective chemical repellent products, but they carry the potential risk of being unsafe for humans and harmful to environment. Insect products derived from natural sources that are safe environmentally friendly becoming increasingly popular. PMD is a broad-spectrum insect present in small amounts Eucalyptus citriodora essential oil (EO). In this...

The extracts of Impatiens noli-tangere, I. parviflora and I. glandulifera (Balsaminaceae) were evaluated for their effect on green peach aphid (Myzus perssicae), an important insect pest of many plants. All the extracts showed insecticidal and repellent activity. After 54 h of exposure, the most active extract was Impatiens parviflora with 99.7 and 90.0 % mortality at 0.5 and 0.1 % concentratio...

In this study, antibacterial, antifungal, antimycobacterial, cytotoxic, antitumor, cardiovascular, antifeedant, insecticidal, antileishmanial and some other single activities of diterpenoids and norditerpenoids isolated from Turkish Lamiaceae plants, are reviewed. The diterpenoids were isolated from species of Salvia, Sideritis, and Ballota species growing in Anatolia. Fifty abietanes, ten kaur...

India with its knowledge of rich ancient traditional systems of medicine provides a strong base for the utilization of a large number of plants in general healthcare. Large number of herbal drugs existing in India, very few has been studied systematically so far. Solanum xanthocarpum is an important medicinal herb in Ayurvedic medicine. Various studies indicated that Solanum xanthocarpum posses...

Cosmetic acceptability and primary skin irritation are the two main parameters for assessing the suitability of any topical formulation meant for protection against the painful bites of mosquitoes. In the present study four newer analogs of N,N-diethyl-2-phenylacetamide (DEPA), were synthesized and formulated for topical application as insect repellent. They were assessed for their irritant beh...

Synthetic insecticides and repellents have been broadly used worldwide for the control of crop pests and insects acting as vectors of human disease. Despite effectiveness, synthetic insecticides or repellents may cause serious damages to the environment and consequently to humans and animals. The growing biotechnological investigation for alternative insecticides and repellents, particularly of...

A eucalyptus-based insect repellent (PMD) with the principal active ingredient p-menthane-3,8-diol was evaluated in the field in comparison with deet. In human landing catches in Tanzania, 3 formulations of PMD were tested against Anopheles gambiae and An. funestus. Repellents, applied to the legs and feet at doses chosen as used in practice, gave complete protection from biting for between 6 a...

Molecular field topology analysis, scaffold hopping, and molecular docking were used as complementary computational tools for the design of repellents for Aedes aegypti, the insect vector for yellow fever, chikungunya, and dengue fever. A large number of analogues were evaluated by virtual screening with Glide molecular docking software. This produced several dozen hits that were either synthes...
