In the search for alternatives to conventional insecticides, essential oils extracted from aromatic plants have been widely investigated. Their toxicities toward insects were of special interest during the last decade. The purpose of this paper is to provide an overview of the data published mostly in the past 10. years on aromatic plant and plant's essential oils that have been reported to possess insecticidal activity and practical methods and recent techniques for screening these compounds. The review refers to 230 plants, their geographical distribution and the organism tested. Some aspects of recent insecticidal activity directed research on natural products are discussed. © 2011.

Essential oils extracted from Lantana camara were tested for fumigant activity against Sitophilus granarius adults. Composition of L. camara essential oil included large amounts of sesquiterpene hydrocarbons, mainly β-caryophyllene. The bioactivity of the essential oil extracted by hydrodistillation from leaves of L. camara was assessed under laboratory conditions. With fumigation bioassays, essential oils showed different activities on S. granarius. April essential oil, after 24 hours of exposure, exerted the highest activity. Similar results were obtained for February and June essential oils after 48 hours of exposure, although December essential oil showed good fumigant activity after 96 hours of exposure. The persistence of the insecticidal efficiency of the essential oil (remanence tests) against S. granarius adults confirmed that June essential oil was efficient for 2 weeks. Even if laboratory bioassays are only the first step towards the use of essential oils in practical applications, these substances represent a possible alternative to chemical insecticides in some market places. © 2012 Taylor & Francis.

The biological effects on Sitophilus granarius were evaluated for three aromatic herbs essential oils: Foeniculum vulgare, Rosmarius officinalis and Lippia citriodora. Stored grain pests were currently controlled by chemical pesticides. This control method leads to pollution of the environment and intoxication of consumers. Essential oils of aromatic plants are more considered as good control alternative tools. Filter papers treated with 5, 50 and 500 μl of test oil were placed in the bottom cover of 1 l plastic bottle. The insects, 50 adults per bottle, were exposed for 1-5 days. Cumulative mortalities were determined 24 and 120 h after treatment. All treatments were replicated five times. The components of the essential oils were identified through GC and GC-MS. The identity of the constituents was confirmed and their relative proportions determined. The results indicate that these natural products may find potential application as useful, environmentally safe insect control and crop protectant agents. © 2011 Elsevier Ltd. All rights reserved.
