Abstract:

Glandular trichomes can defend (Medicago species from herbivores in a variety of insect orders. Wild alfalfas with high concentrations of glandular trichomes occur in a restricted portion of the geographical range of the species (Medicago saliva L. sensu lato), especially in the Caucasus, Ukraine, and adjacent areas of the USSR. These observations suggest that this adaptation was developed to defend the alfalfa against insect pests with similar geographical distribution. That M. sativa plants with pods covered with glandular hairs tend to have larger, if fewer, seeds than plants with pods lack

Abstract:

Alfalfa (Medicago sativa) is the most important forage legume and one of the most widely grown crops in Serbia. Aphids (Hemiptera: Aphididae) are one of the most significant groups of pests of that crop. Three aphid species, Acyrthosiphon pisum, Aphis craccivora and Therioaphis trifolii, are considered as important pests of alfalfa in Serbia. The most abundant of them, T. trifolii, is more adapted to warmer temperatures and it is the predominant aphid species during summer months, while A. pisum is prevalent during the spring period. In warmer climates, an increasing abundance of T. trifolii a

Abstract:

Alfalfa is one of the most important legume forages in the world and contributes greatly to the improvement of ecosystems, nutrition, and food security. Diseases caused by pathogens and pests severely restrict the production of alfalfa. Breeding resistant varieties is the most economical and effective strategy for the control of alfalfa diseases and pests, and the key to breeding resistant varieties is to identify important resistance genes. Plant innate immunity is the theoretical basis for identifying resistant genes and breeding resistant varieties. In recent years, the framework of plant i

Abstract:

Interactions of insect pests and their natural enemies increasingly are being considered from a metapopulation perspective, with focus on movements of individuals among habitat patches (e.g., individual crop fields). Biological control may be undercut in short-lived crops as natural enemies lag behind the pests in colonizing newly created habitat. This hypothesis was tested by assessing parasitism of cereal leaf beetle (Oulema melanopus) and alfalfa weevil (Hypera postica) larvae at varying distances along transects into newly planted fields of small grains and alfalfa in northern Utah.

As a substitute for pesticides, crop rotation has been most rewarding in the control of nematodes; sugarbeet cyst and root knot nematode examples are detailed.

This leads to difficulties in suppresses and reduction of pests, diseases and weeds at the yield of alfalfa.

Weeds generally have low nutritional value, unpleasant smell and taste, and also affect the quality of alfalfa seeds.

Abstract:

The article presents the results of experimental research on the pneumatic collection of pests of agricultural crops. Today, insect pests are one of the main problems in agriculture. Pests cause 20 to 40 percent of global crop losses every year, and pesticide treatment is the main method of control. The continuous use of pesticides leads to potential human diseases, plant and soil pollution, so much attention is paid to ecological control methods. Pneumatic collection of pests is the main and most effective means of control. And the development of new designs and devices for its implementation

Abstract:

Lygus hesperus Knight (Miridae: Hemiptera), a key pest of cotton in the United States, is a highly polyphagous insect. Upland cotton (Gossypium hirsutum L. var. hirsutum) and alfalfa (Medicago sativa L.) are two major field crop hosts of Lygus hesperus in the Texas High Plains. While alfalfa is considered a source of Lygus in cotton, Lygus intercrop movement behavior has not been fully characterized in cotton-alfalfa systems. Understanding the intercrop movement behavior of Lygus may facilitate better decision-making for Lygus management in these crops. A series of studies including a mark-rel

Abstract:

Alfalfa (Medicago sativa), recognized as the most valuable legume feed crop, faces significant challenges in enhancing both qualitative and quantitative production amidst the pressures of climate change. This review highlights these challenges, including the underutilization of genomic and genetic resources, while proposing potential solutions through genome editing. Our focus is on leveraging CRISPR/Cas technology in conjunction with decades of advancements in conventional breeding to expedite the improvement of alfalfa. By adopting this approach, we aim to overcome the limitations of traditi

Abstract:

Alfalfa is a valuable high-protein fodder crop suitable for the preparation of various types of feed (green mass, hay, haylage, silage). Due to the increasing aridity of the climate, there is a need to expand its crops in the northern regions of the country. Currently, it is necessary to create alfalfa varieties with a good adaptation to modern environmental conditions, to improve the development of seed production of this crop. Often alfalfa plants are highly susceptible to disease damage, damage by pests. Fungal diseases (fusarium, brown spotting) during the epiphytotic period can also reduc

The beet webworm Loxostege sticticalis has caused significant economic losses to the production of agriculture and animal husbandry in China. Preference testing of larva feeding and adult oviposition and flight capability tests were carried out on five host plants: soybean, pigweed, pea, broad bean, and alfalfa. An experimental population life table and population growth trends over the subsequent 200 days were constructed. The test results show that the larvae showed no significant preference among different plants. However, adults lay more eggs on soybeans. The pests failed to complete a gen

Abstract:

For both New Zealand and China, agriculture is integral to the economy, supporting primary production in both intensive and extensive farming systems. Grasslands have important ecosystem and biodiversity functions, as well providing valuable grazing for livestock. However, production and persistence of grassland and forage species (e.g. alfalfa) is not only compromised by overgrazing, climate change and habitat fragmentation, but from a range of pests and diseases, which impose considerable costs on growers in lost production and income. Some of these pest species are native, but increasingly,
