Comparative Efficiency of Certain Products against some Piercing-Sucking Pests and their Associated Predators on Cotton Plants

Toxic Effect of Capsicum and Garlic Xylene Extracts in Toxicity of Boiled Linseed Oil Formulations against Some Piercing Sucking Cotton Pests

Capsicum and garlic were extracted in xylene. The obtained extracts were used to prepare four emulsifable concentrates "EC's". Formula A "capsicum xylene extract + emulsifier", Formula B "garlic xylene extract + emulsifier", Formula C "capsicum xylene extract in boiled linseed oil + emulsifier" and Formula D "garlic xylene extract in boiled linseed oil + emulsifier ". All prepared formulations ...

Toxicity of Aromatic Plants and Their Constituents Against Coleopteran Stored Products Insect Pests

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

New insights into an RNAi approach for plant defence against piercing-sucking and stem-borer insect pests.

Insect double-stranded (ds)RNA expression in transgenic crops can increase plant resistance to biotic stress; however, creating transgenic crops to defend against every insect pest is impractical. Arabidopsis Mob1A is required for organ growth and reproduction. When Arabidopsis roots were soaked in dsMob1A, the root lengths and numbers were significantly suppressed and plants could not bolt or ...

Influence of cover crops on insect pests and predators in conservation tillage cotton.

In fall 2000, an on-farm sustainable agricultural research project was established for cotton, Gossypium hirsutum L., in Tift County, Georgia. The objective of our 2-yr research project was to determine the impact of several cover crops on pest and predator insects in cotton. The five cover crop treatments included 1) cereal rye, Secale cereale L., a standard grass cover crop; 2) crimson clover...
