varieties of mustard and rape examined for resistance to. resistance is one of the most effective means of controlling insect pests in sorghum. 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.

Common name Mealy cabbage aphid Latin name Brevicoryne brassicae Plants affected Cabbage, cauliflower, Brussels sprout, swede and other brassicas Main symptoms Greyish white aphids cluster underneath the leaves and on growing points.
Leaves distorted and discoloured on young plants Caused by A sap-sucking insect Timing April-October. aimed to characterize and compare feeding behaviour of cabbage aphid for resistance screening in Brassica germplasm and classify the germplasm into susceptible or resistant groups based on the acceptability of feeding on each genotype.
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.

No source for aphid resistance is presently available in Brassica juncea. A wild crucifer, Brassica fruticulosa is known to be resistant to mustard aphid. An artificially synthesized amphiploid, AD-4 (B.

The oil seed Brassica is infested by green peach aphid (Myzus persicae S.), cabbage aphid (Brevicoryne brassicae L.) and turnip aphid (Lipaphis erysimi Kalt.).B. juncea (Indian mustard) is predominantly infested by L. erysimi whereas two other species B.
brassicae, and M. persicae also occur. All growth stages of the crop are attacked by aphids but the greatest damage is Cited by:. The data for B. brassicae are limited to three plantings, because these aphids occurred in substantial numbers in only one of the two locations, and not in all plantings at that location.
