A new notion of coneigenvalue was introduced by Ikramov in [Kh.D. Ikramov. On pseudo-eigenvalues and singular numbers of a complex square matrix (in Russian). Zap. Nauchn. Semin. POMI, 334:111–120, 2006.]. This paper presents some majorization inequalities for coneigenvalues, which extend some classical majorization relations for eigenvalues and singular values, and may serve as a basis for fur...
تریپس ها و شته ها از آفات مهم محصولات گلخانه ای هستند که علاوه بر خسارت مستقیم با انتقال بیماری های ویروسی مشکلات دوچندانی به وجود می آورند. در سال های اخیر از سنک های جنس Orius spp به دلیل قدرت بالای شکارگری به عنوان عامل کنترل بیولوژیک این آفات مکنده، به ویژه در گلخانه ها استفاده می شود. یکی از معیارهای مهم در بررسی کارایی شکارگران و پارازیتوییدها، واکنش آنها به تغییر تراکم میزبا...
BIOLOGY/ECOLOGY Dispersal mechanisms Flight range of winged adults is very limited. Long-range dispersal of eggs, immature stages and adults is manmediated with the transport of infested plant material. Reproduction The taxonomic status of this alien aphid is problematic, and hence the interpretation of biological information is difficult. Moreover, different biotypes exhibiting host preference...

Little is known about the mechanisms by which plant genotype shapes arthropod community structure. In a field experiment, we measured the effects of milkweed (Asclepias syriaca) genotype and ants on milkweed arthropods. Populations of the ant-tended aphid Aphis asclepiadis and the untended aphid Myzocallis asclepiadis varied eight- to 18-fold among milkweed genotypes, depending on aphid species...
