Heat stress is a major environmental limiting wheat productivity in most cereal growing areas of the world. The objective this study was to evaluate heat tolerance durum (Triticum turgidum var. durum) genotypes. For purpose, 45 genotypes were grown during two seasons (2012–2013 and 2013–2014) under non-stress (normal sowing) heat-stress (late conditions. indices calculated based on grain yield normal sowing (Yp) late (Ys) Results combined analysis variance showed significant influences as...

The lesser grain borer, Rhyzopertha dominica (F.), causes damage to stored grains resulting in both quantitative and qualitative losses. use of synthetic fumigants the management stored-product pests resulted undesirable side effects such as environmental contamination threat human animal health. In this study, lethal sublethal essential oils from four Eucalyptus species, E. microtheca, procera, spatulata, torquata were studied against R. adults. Gas chromatographic-mass spectral analysis...

Meloidogyne spp. are important parasitic nematodes affecting a variety of plants worldwide. We investigated the nematicidal properties specific compounds found in bio-fumigant plants, particularly linalool, nonanal, methylene chloride, and 2-Decanal. Laboratory findings revealed that chloride 2-Decenal effectively reduced populations second-stage juveniles (J2s). Additionally, research explored effects tomato (Solanum lycopersicum L.) on M. incognita J2s, observing leaves significantly...

Toxicity of Essential Oil Agastache Foeniculum (Pursh) Kuntze to Oryzaephilus Surinamensis L. and Lasioderma Serricorne F. The essential oil aerial parts foeniculum (Lamiaceae) was isolated by hydrodistillation method constituents were analyzed gas chromatography mass spectrometry (GC-MS) method. Methyl chavicol, 1,8-cineole, 1-octen-3-ol, 3-octanone germacrene D the predominant components oil. chavicol (94.003%) identified as a major component in tested for toxicity against adults...

Inert dust insecticides (IDIs) can make a significant contribution to Integrated Pest Management (IPM) programs of stored grain providing insect control and preserving quality during storage. Unlike chemical-based insecticides, IDIs are unaffected by even high summer temperatures maintain efficacy for many months rather than the days or weeks their chemical counterparts. Their three main applications structural treatment empty storage facilities grain- handling machinery; commodity capping...

Plant secondary metabolites play an important role in plant-insect interactions and therefore such compounds may have insecticidal activity against insects.The chemical composition of the essential oil from leaves flowers Lavandula stoechas grown Kashan, Iran, was studied by gas chromatography mass spectrometry (GC-MS).1,8-Cineole (7.02%), γ-Cadinene (5.33%), T-Cadinol (5.07%), p-Mentha-1-en-8-ol (5.02%) Caryophyllene (5.01%) were found to be major constituents oil.In fumigant toxicity tests...

The uncontrolled use of synthetic insecticides is a great hazard for the environment and consumers.Essential oils were introduced as low toxic agents against mammals non-targeted insects.In this study, essential oil from aerial parts blue giant hyssop (Agastache foeniculum [Pursh] Kuntze) (Lamiaceae) was isolated by water steam distillation method with Clevenger apparatus, its chemical composition studied gas chromatography mass spectrometry.The toxicity A. red flour beetle, Tribolium...

Inspite of well-established potentiality plant essential oils as biopesticides, their environmentally low persistence is considered a hindering obstacle for its commercialization. In the present study, chemical composition and toxicity isolated from leaves Thymus eriocalyx kotschyanus were evaluated against two-spotted spider mite, Tetranychus urticae. The chemicals in crude oil found to be thymol (28.83%), oleic acid (11.51%), palmitic (8.60%), borneol (5.72%), ρ-cymene (3.60%), 1,8-cineole...

The use of chemical insecticides has had several side-effects, such as environmental contamination, foodborne residues, and human health threats. utilization plant-derived essential oils efficient bio-rational agents been acknowledged in pest management strategies. In the present study, fumigant toxicity oil isolated from Satureja intermedia was assessed against cosmopolitan stored-product insect pests: Trogoderma granarium Everts (khapra beetle), Rhyzopertha dominica (Fabricius) (lesser...

Although the use of synthetic chemicals is principal method for insect pest management, their widespread application has led to numerous side effects, including environmental pollution and threats human animal health. Plant essential oils have been introduced as promising natural substitutes insecticides. However, high volatility and/or low durability are main limiting factors oil control pests. Accordingly, along with an evaluation fumigant toxicity Eucalyptus largiflorens against cowpea...

In the present study, toxicity of essential oils Mentha piperata L. and pulegium pathogenicity Lecanicillium muscarium (Zare & Gams) were studied in melon aphid, Aphis gossypii Glover. Analyses by GC-MS indicated limonene (27.28%), menthol (24.71%), menthone (14.01%), carvol (8.46%) M. oil pulegone (73.44%), piperitenone (5.49%), decane (4.99%), (3.07%) as main components. Both pathogenic fungus had useful against A. gossypii. Probit analysis LC50 values (lethal concentrations to kill 50%...

In the present study, toxicity and physiological disorders of essential oil isolated from Artemisia annua flowers were assessed against one main insect pests mulberry, Glyphodes pyloalis Walker, announcing safe effective alternatives to synthetic pesticides. The LC50 (lethal concentration kill 50% tested insects) values oral fumigant bioassays A. 1.204 % W/V 3.343 μL/L air, respectively. oil, rich in camphor, artemisia ketone, β-selinene, pinocarvone, 1,8-cineole, α-pinene, caused a...

One of the new ways warehouse pest control is carbon dioxide treatment, which had no residues on target products. In present research, at first, CO

The root-knot nematode (Meloidogyne incognita) is a plant pathogen that causes significant economic damage to important food crops. nematicidal and insecticidal effects of the essential oil extract root stem different species Eupatorium have been studied in several countries. We investigated impact stems leaves E. adenophorum on second-stage juveniles (J2s) M. incognita. Nematode mortality decreased by root-stem treatment increasing temperature time. Nematodes (J2) were more sensitive than...

Abstract The essential oils, with known effects on insects, could be an alternative method to classical insecticides. In the present study, oils of Agastache foeniculum (Pursh) Kuntze, Anethum graveolens L., Cuminum cyminum Foeniculum vulgare Gaetner and Satureja hortensis L. were isolated by hydrodistillation using Clevenger apparatus their insecticidal activities determined against Callosobruchus maculatus adults through fumigant bioassay.
