In natural ecosystems, biological relationships have serious effects on system stability. Allelopathic is negative or positive effect of a plant on other plant growth. Today this word is used for rangelands, same as agricultural areas. Because of good herbage production, Medicago is most common plant in agricultural rotations and rangelands. Therefore investigation of its allelopathic qualities...

Herbivorous insects are characterized by a great diversity of host plant associations, yet, the processes driving host range evolution are not fully understood. When herbivores encounter a novel host, local selection pressures are expected to shape traits that mediate plant–insect interactions. I show that a leafmining fly, Amauromyza flavifrons (Meigen) (Diptera: Agromyzidae), suffers a profou...
