SCREENING FOR SUCKING PESTS (THRIPS AND JASSIDS) RESISTANCE/TOLERANCE IN COTTON GERMPLASM LINES (GOSSYPIUM HIRSUTUM L.) G. TH*, YALLAPPA HARIJAN AND I. S. KATAGERI Agricultural Research Station, Dharwad Farm, UAS, Dharwad - , INDIA e-mail: [email protected] INTRODUCTION Cotton (Gossypium .   Abstract: The soybean germplasm contains several genes that provide resistance to the soybean aphid, Aphis glycines Matsumura, (Rag-genes). These genes can limit A. glycines population growth and prevent yield loss. However field tests of Rag-containing soybean are never free of aphids. The cabbage family (Brassica) has formed an important part of our diet for hundreds if not thousands of years. Because man has bred the plants for productivity and flavour over the years they are, like any thoroughbred, vulnerable to pests and diseases. Luckily most brassica problems have a solution. Clusters of small (approximately 2mm) yellow. Evaluation #1 - host plants / resistance. Infested Octo / 10 aphids per plant, when plants were leaves. Evaluated 12 November, for: Chlorosis / Damage rating (1 – 9) Plant height, Leaf number (node number).

  Abstract. The green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae), is an important pest of many crops in the world and a vector of more than plant viruses. It is a major pest of Brassica vegetables such as Chinese cabbage in northern China. Chemical control is extensively used to manage this aphid around the world; however, development of Cited by: 1. In 3 field trials in , Vigna radiata and V. sublobata accessions were screened for Ostrinia furnacalis resistance. In the first test, 35 of the 85 V. radiata entries assessed showed moderate resistance. In the second test, of the 13 V. radiata accessions evaluated only V had less damage than the susceptible control, VCA. In the third test (24 V. sublobata entries), .   Scientists Find Aphid Resistance in Black Raspberry By Sharon Durham Octo There's good news for fans of black raspberries: A U.S. Department of Agriculture (USDA) scientist and his commercial colleague have found black raspberries that have resistance to a disease-spreading aphid.. Agricultural Research Service (ARS) horticulturist Chad Finn . researchers who worked with ~ 86 ~ Journal of Entomology and Zoology Studies Brassica plants and found highly resistant to aphid while different species of Brassica showed diversity in their relation to L. erysimi from highly susceptible to highly tolerant [3, 7, 11, 17, 20,].

that have some inducible resistance to aphids, a plant could be used that's susceptible to aphid attack to 'switch on' the defence mechanism through the natural underground connection. (, ). Screening and identification of resistant germplasm is fundamental and continuous process for sustain-able production (Akhtar et al., ). Focus Group IPM for brassica 18 Strategies to control Alternaria brassicae and A. brassicola also consist of disease free seed, crop rotation, tolerant/resistant cultivars, reduced plant densities for better aeration and reduced N fertilization. In most years, Alternaria is sufficiently controlled by these measures. Economically. Aphids are one of the most harmful non-indigenous threats to agriculture in the United States. The consequences directly caused by aphids include production losses, quality decreases, and agricultural risk increases (Miller et al., ). For example, in the western U.S., the yield losses caused by Russian wheat aphids reached $$File Size: KB.   The IAC soybean variety was developed in Brazil and has resistance to stink bugs. Each plot will be harvested and yield and quality (% of the kernels damaged by stink bugs) will be determined. Progress 07/01/04 to 06/30/05 Outputs Stink bugs (primarily southern green, brown and green stink bugs) are the number one pest of Georgia's soybean.

ICRISAT ho accessions of the sorghum germplasm from all over the world. Therefore, extensive screening of the sorghum germplasm was undertaken, and several stable sources of resistance to the key insect pests have been identified.

Beginner. Scientific Names Myzus persicae, Brevicoryne brassicae, Lypaphis erysimi. Identification. Small, pear-shaped insects, with cornicles or “tail-pipes” near the tip of their abdomen; Typically found in colonies located on the underside of the leaf, or along the stem or petioles; Aphids pierce the leaves and suck the sap from many vegetable crops, causing leaf.

Key words: Rice germplasm, Screening, Yellow stem borer, Resistance INTRODUCTION Rice (Oryza sativa L.) is one of the most significant cereals and is the staple food for more than 2 billion people.

Almost 90 percent of the rice is grown and consumed in Asia. India is the second largest rice producing country in the world.

Multiple Aphid Resistance from Alien Sources and Its Chromosomal Location in Bread Wheat Abstract Wheat (Triticum aestivum) is a very important cereal crop and is cultivated worldwide on more than million hectares annually, with an average grain yield of about 3 t/ Size: 1MB.

Stemphylium blight is an important fungal disease of lentil caused by Stemphylium botryosum. It occurs in all major lentil growing regions of the world, including Bangladesh, India, Nepal, Syria, USA and Canada. As lentil production in Australia is increasing, stemphylium blight is considered a potential threat to the industry.

However, information on this pathogen and Cited by: 4. The ascochyta blight resistance of 14 chickpea cultivars, 29 imported chickpea lines and 38 local breeding lines to four Australian isolates of Ascochyta rabiei was investigated.

Each isolate was tested individually on each chickpea genotype. There were no differences between the four isolates in their pathogenicity. However, there were large differences Cited by: Aphids, particulary the cabbage aphid (Brevicoryne brassicae) are the major pest causing economic damage to rape production in Zimbabwe (Dube).

Under favorable conditions, feeding damage from large number of aphids can kill seedlings and young transplants, on larger plants, its feeding results. Resistance against aphids is critical trait for the stability and sustainability of barley production.

Very few sources of resistance are available against corn leaf aphid in India. Thus, a large collection of accessions acquired from Directorate of Wheat Research, Karnal under a Network Project on barley germplasm evaluation was screened against corn leaf aphid in : Beant Singh, Sarvjeet Singh.

The aphids feed on many varieties of produce, including cabbage, broccoli (especially), Brussels sprouts, cauliflower and many other members of the genus Brassica, but do not feed on plants Family: Aphididae.

SCREENING OF BRASSICA GERMPLASM FOR RESISTANCE TO MAJOR DISEASES in the evening with conidial suspension ( conidia/ml) of Alternaria brassicae (Kolte, b).

The concentration was adjusted with the help of haemocytometer. Proper moisture in the field was maintained for 2 days after inoculation. Cabbage aphids are found on all plants in the cruciferous family: cabbage, rape, swedes, turnips, broccoli, brussels sprouts, cauliflower, kale, mustard and some weed species.

It is the most common aphid found on these plants and usually the most abundant. For this, resistant sources need to be identified first. Up to now there were no methods suitable for high throughput phenotyping of plant germplasm to identify sources of resistance towards phloem-feeding insects.

Results. In this paper we present a high throughput screening system to identify plants with an increased resistance against by: In a separate field study, the host plant resistance against aphids enhanced the parasitism of aphid species, Sitobion avenae (F.) by its parasitoid Aphidius spp.

The feeding behaviour assessment revealed the presence of both interspecific and intraspecific. The sugarcane aphid Melanaphis sacchari (Zehntner) (Homoptera: Aphididae) was first discovered on sorghum [Sorghum bicolor (L.) Moench], in the United States in Florida as early (Wilbrink ), and later confirmed by Denmark (), although it also has a history of infesting sugarcane, Saccharum officinarum (L.), in Florida (MeadDenmark ) Cited by: eliminate the aphids from the product.

Grey aphids are also known as cabbage aphids. If you want to get scientific, they go by Brevicoryne brassicae. According to the University of California Agriculture & Natural Resources, these pests occur in dense colonies and “prefer to feed on the youngest leaves and flowering parts and are often found deep within the heads of cabbages or.
