indian meal moth, plodia interpunctella hubner is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repellent activity of 18 p...

the potato tuber moth (ptm), phthorimaea operculella zeller (lepidoptera: gelechiidae), is an important pest of potato and other solanaceous plants. it is cosmopolite and oligophage that exists in most countries where potatoes are grown. because of chemical treatment adverse effects, there is a necessity to find safe alternatives to synthetic insecticides. so, medicinal plants are promising sin...

the red flour beetle, tribolium castaneum (herbst), is one of the most destructive pests attacking stored grain products all over the world. serious problems assossiated with using synthetic chemical insecticides have strongly demonstrated the need for applying alternative safe compounds such as plant essential oils. the present experiment was conducted to evaluate fumigant toxicity of essentia...

Purpose: To investigate the insecticidal activity of the essential oil of Cinnamomum cassis and its main constituent compound, trans-cinnamaldehyde, against the booklice, Liposcelis bostrychophila. Methods: Steam distillation of C. cassis twigs was carried out using a Clavenger apparatus in order to obtain the volatile oils. Gas chromatography/mass spectrometric (GC/MS) analyses (HP-5MS column)...

the essential oils of aerial parts of three medicinal plants artemisia khorassanica podl., rosmarinus officinalis l. and mentha longifolia l. were isolated by hydrodistillation and investigated for their toxicity and repellency against tribolium confusum jacquelin du val. at 27 ± 1 ºc and 60 ± 5% rh in darkness. the mortality of the adults increased with concentration from 185 to 1111 μl/l air ...

b a ckground: the efficacy of essential oil of chenopodium ambrosioides flowering aerial parts and its three main active ingredients was evaluated against blattella germanica male adults. m e t hods: composition of essential oil was determined by gc-ms. topical application bioassay was used to evalu- ate contact toxicity of essential oil and three main components. fumigant toxicity of essential...

fumigant toxicity of various doses of essential oils (185.2, 370.4, 555.5, 740.7, 925.4, 1111.1, and 1296.3 µl/l water) from five officinal plants, including rosemary (rosmarinus officinalis), lavender (lavandula vera), fennel (foeniculum vulgare), tarragon (artemisia dracunculus)and summer savory (satureja hortensis)on two stored products pests, cowpea weevil (callosobruchus maculatus) and red...

Growth and yield of cotton were best with combinations of fumigants and organophosphate and carbamate nematicides. Organophosphates or carbamates used alone did not give season-long control of root-knot nematodes. Long-term control was poor because the temporary sublethal effects of these materials diminished soon enough lhat the nematodes could reproduce. The nematodes survived the treatments ...

Background: Nowadays stored–product insect pests are controlled by pesticides and chemical fumigant compounds. The continueous use of chemical pesticides is harmful for non–target creatures specially humans and other mammals. Beside they polluted the environment. Objective: Accoring to the studies, the essential oil of Labiatae plants have insecticidal activity against some pests. In this st...

The objective of the current study was to determine the chemical constituents and fumigant toxicity of the essential oil isolated by hydrodistillation form Juniperus foetidissima. The chemical composition of the essential oil was determined by GC and GC-MS. The essential oil included large amounts of monoterpenes 51.4%, with citronellol being the major compound thereof, and sesquiterpines 42.4%...
