Effects of Melia azedarach extract on demographic and biochemical characteristics of the cabbage aphid, Brevicoryne brassicae.

The cabbage aphid, Brevicoryne brassicae L. (Aphididae: Hemiptera) a destructive aphid, is native to Europe and is now found in many other parts of the world. Currently, one of the main problems of Iranian cabbage growers is the significant damage caused by this pest.

Biology and life table parameters of Brevicoryne brassicae (Hemiptera: Aphididae) on cauliflower cultivars.

In this article, the biology and fertility life table parameters of the cabbage aphid, Brevicoryne brassicae (L.) (Hemiptera: Aphididae), were studied on cauliflower leaves, Brassica oleracea var. botrytis (Brassicales: Brassicaceae), of the cultivars Smilla, Snow mystique, White cloud, Buris, Galiblanka, Snow crown, SG, and Tokita.

Effect of temperature on developmental rate of Sesamia cretica (Lepidoptera: Noctuidae) immature stages.

Effect of temperature on development of pink stem borer, Sesamia cretica Lederer, was studied at eight constant temperatures (15, 18, 20.5, 24, 27, 30, 34, and 38°C), a photoperiod of 16:8 (L:D) h, and 50-60% rela\tive humidity. The larvae of pink stem borer were reared on cutting stems of maize.

Pathogenicity of the entomopathogenic fungus Metarhizium anisopliae var. major on different stages of the sunn pest Eurygaster integriceps.

The sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), is the most important insect pest of wheat and barley. The population management of this pest is of major concern to wheat producers. One of the potential control strategies is to use entomopathogenic fungi.

Fumigant toxicity and oviposition deterrency of the essential oil from cardamom, Elettaria cardamomum, against three stored–product insects.

Use of insecticides can have disruptive effects on the environment. Replacing the chemical compounds in these insecticides with plant materials, however, can be a safe method with low environmental risk. In the current study, chemical composition and insecticidal activities of the essential oil from cardamom, Elettaria cardamomum L.

The fruit essential oil of Pimpinella anisum L. (Umblliferae) induces neuronal hyperexcitability in snail partly through attenuation of after-hyperpolarization.

Aim Of The Study: Many biological actions of Pimpinella anisum L. (Ainse), including antiepileptic activity have been demonstrated; however, there is no data concerning its precise cellular mechanisms of action. We determined whether the fruit essential oil of anise affect the bioelectrical activity of snail neurons in control condition or after pentylenetetrazol (PTZ) induced epileptic activity.

Developmental time and fecundity of white peach scale, Pseudaulacaspis pentagona (Targioni-Tozzetti) (Homoptera: Diaspididae), on potato, kiwi and mulberry hosts in Iran.

The white peach scale (WPS), Pseudaulacaspis pentagona (Targioni-Tozzetti) (Homoptera: Diaspididae), is a world wide polyphagous scale insect. It is widely distributed in north of Iran, near the Caspian Sea areas, where it is the main pest of mulberry and kiwi trees. The development and fecundity of P.
