In sorghum (Sorghum bicolor L. Moench) cultivation, the main pest is sugarcane aphid (Melanaphis sacchari Zehntner (Hemiptera: Aphididae)). The insecticide imidacloprid frequently used to control this insect, and in some cases, it complemented with release of lacewings species Chrysoperla carnea Stephens (Neuroptera: Chrysopidae). has been shown be harmful non-target insects, such as natural en...

BACKGROUND Papaveraceae Argemone mexicana L., Burseraceae Bursera simaruba (L.) Sarg., Acanthaceae Justicia spicigera Schltdl. and Selaginellaceae Selaginella lepidophylla (Hook. & Grev.) Spring., have been used in Mexican traditional medicine to treat hypertension. The objective of this study was to further characterize the cardiovascular effects of the methanol extracts of such plants. METH...

In January 2005, a cyclone hit southern Madagascar, including the Beza Mahafaly Special Reserve, disrupting the flowering/fruiting cycle of Tamarindus indica, leaving Lemur catta without its major food resource during reproductive periods. We studied two adjacent groups of L. catta during the late gestation period, and both groups ventured outside the reserve to feed. The Red group (RG) fed dai...

Airborne biological allergens trigger an allergic response required for the development of atopic disease. Biological allergens are released into the air by wind, rain and active discharge mechanisms. In this review article an attempt has been made to evaluate the published literature on prevalence and types of air borne allergens in India. Important pollen allergens reported from India were: P...

The present study was designed to evaluate relative contribution of different polyphenols (total phenolics, flavonoids, flavonols) and their antioxidants activities in aqueous extracts of different parts of some plants; Argemone mexicana, Datura metel, Calotropis procera, Thevetia peruviana, and Cannabis sativa. The antioxidants (total phenolics, flavonoids, flavones) were determined by chemica...

OBJECTIVE Argemone mexicana is a Papaveracea plant; some reports have shown their antibacterial, anti-cancer, sedative and probably anti-anxiety properties. From their aerial parts, flavonoids and alkaloids have been isolated, which are intrinsically related to some actions on the central nervous system. The aim of this study was to evaluate the anxiolytic-like effects of the plant, using its e...
