The effect of essential oil Origanum vulgare L. a medicinal plant was studied on toxicity, physiology and biochemical characteristics diamondback moth Plutella xylustella in controlled condition. LC10, LC30 LC50 values were estimated 0.234, 0.710 1.528 percent (v/v) respectively for 3rd instar larvae. Repellency under LC10 concentrations 22.8 ± 6.64 49.8 6.95 respectively. Effect feeding efficiency also evaluated concentrations. Approximately Digestibility (AD), Efficacy Conversion Ingested...

Abstract The essential oils of Thymus vulgaris L. and Origanum vulgare were investigated for their toxicity physiological aspects on the lesser mulberry pyralid Glyphodes pyloalis Walker in controlled condition (24±1°C, 75±5% RH 16L : 8D). leaf disc method was used to study acute toxicity, effect LC 10 , 30 50 feeding efficiency 4th instar larva, biochemical indices. oil doses estimated be 0.107%, 0.188% 0.279% T. vulgaris, 0.67%, 1.173% 1.728% O. vulgare, respectively. results showed that...

Physiological and Biochemical Effect of Pyriproxyfen on Indian Meal Moth Plodia Interpunctella (Hübner) (Lepidoptera: Pyralidae) Insect growth regulators generally have a selective effect the target insects practically no apparent side non-target organisms especially vertebrates. Hence, insect could be suitable choice to control pests in stored products. Ten-day-old larvae meal moth interpunctella were expressed juvenile hormone analogue pyriproxyfen order an growth, metamorphosis,...

The lesser mulberry pyralid, Glyphodes pyloalis Walker (Lepidoptera: Pyralidae) is a monophagous and dangerous pest of that has been recently observed in Guilan province, northern Iran.

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...
