background & aim: the use of herbal extracts as safe and effective factors for eradicating of stores pests has attracted much attention. in this paper, the bio-effects of fumigation and repellent effects of essential oil of eucalyptus globolus were investigated on red flour beetle. experimental: in this study, the toxicity, fumigation and repellency contacts were assayed by topical applicat...
Chemical composition of the essential oil from Thymus carmanicus Jalas, and its fumigant activity was investigated against two stored product insects, Callosobruchus maculatus (F.) and Sitophilus granarius (L.). Essential oil was isolated via hydrodistillation from dry leaves of T. carmanicus using a modified Clevenger-type apparatus and the chemical composition of the oil was assessed via GC a...
To develop natural product resources to control cigarette beetles (Lasioderma serricorne), the essential oil from Artemisia lavandulaefolia (Compositae) was investigated. Oil was extracted by hydrodistillation of the above-ground portion of A. lavandulaefolia and analyzed using gas chromatography-mass spectrometer (GC-MS). Extracted essential oil and three compounds isolated from the oil were t...
Damage to cotton by Rotylenchulus reniformis below plow depth was evaluated in a sandy clay loam soil at Weslaco, Texas. In December 1999, 14 holes on 51-cm centers were dug 91 cm deep along the planting bed and adjacent furrow and 2 ml of 1,3-dichloropropene was placed 91, 61, and 30 cm deep as each hole was refilled and packed. This technique eliminated 96%, 81%, and 74% of R. reniformis down...
Abstract The green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae), is an economically important cosmopolitan crop pest. Essential oils (EOs) are complex mixtures of secondary metabolites that exhibit a wide range biological activities, including antioxidant, antimicrobial and anti-inflammatory activities. Monoterpenes, as the major constituents EOs, well known for having In this st...
The aim of this research was to determine chemical composition and insecticidal activity of the essential oil of Illicium pachyphyllum fruits against two grain storage insects, Sitophilus zeamais and Tribolium castaneum, and to isolate any insecticidal constituents from the essential oil. The essential oil of I. pachyphyllum fruits was obtained by hydrodistillation and analyzed by GC-MS. A tota...
