The nutritive value of the annual alfalfa (Medicago rigidulla, Medicago polymorpha and Medicago scutellata) species harvested at flowering stage was assessed by chemical composition, in vitro dry matter and nitrogen digestibility, in sacco dry matter and nitrogen degradation (0, 8, 12, 24, 48 and 72 h) and palatability (short-term intake rate, STIR) methods. Mean values of the chemical analysis...

The fruit fly Bactrocera caudata is a pest species of economic importance in Asia. Its larvae feed on the flowers of Cucurbitaceae such as Cucurbita moschata. To-date it is distinguished from related species based on morphological characters. Specimens of B. caudata from Peninsular Malaysia and Indonesia (Bali and Lombok) were analysed using the partial DNA sequences of cytochrome c oxidase sub...
The invasion of Africanized honeybees (Apis mellifera L.) in the Americas provides a window of opportunity to study the dynamics of secondary contact of subspecies of bees that evolved in allopatry in ecologically distinctive habitats of the Old World. We report here the results of an 11-year mitochondrial DNA survey of a feral honeybee population from southern United States (Texas). The mitoch...
BACKGROUND Snail medic (Medicago scutellata L.) seeds exhibit a significantly higher content of a trypsin inhibitor than other Medicago species. This inhibitor belongs to the Bowman-Birk family of serine protease inhibitors (BBI) and exhibits a good sequence homology with the BBI from soybean, while presenting some differences. It has been suggested that BBIs have antitumoral and radio-protecti...
In order to evaluate and compare the yield of mixed and pure range land species, this research was carried out of semi-Arid of Gonbad Kavous. The plan was designed complete Blok with three replications in crop year of 2012-2013. The treatments were with 5 levels of monoculture planting pattern included, Festuca ovina L, Festuca arundinacea Schreb, Medicago scutellata L, Agropyron elongatum Anal...
چکیده- گونه های یونجه یکساله (medicago spp.)، که بومی مناطق مدیترانه ای هستند، به طور گسترده در مزارع و مراتع ایران کشت می شوند. روش های مختلفی برای کشت یونجه های یکساله وجود دارد؛ و اگرچه روش کشت بر نمود گیاه اثر می گذارد، ولی اطلاعات کمی در مورد روش های کشت یونجه های یکساله وجود دارد. به منظور بررسی تاثیر روش های کاشت (دست پاش و کشت ردیفی) بر ویژگی های کمی و کیفی سه گونه یونجه یکساله (m...
Honey bee colonies exhibit a wide range of behavioral variations depending on genetic origin and environmental factors. Therefore, the performance evaluation honey races is critical to laying foundation for future selection improvement in Ethiopia. Thirty Apis mellifera scutellata (A. m. scutellata) similar resources contained hive were kept improved box hives evaluated through various behavior...
Morphometric and genetic changes in a population of Apis mellifera after 34 years of Africanization.
Though the replacement of European bees by Africanized honey bees in tropical America has attracted considerable attention, little is known about the temporal changes in morphological and genetic characteristics in these bee populations. We examined the changes in the morphometric and genetic profiles of an Africanized honey bee population collected near where the original African swarms escape...
