Sugarcane27
The sugarcane aphid, Melanaphis sacchari , was discovered late in the 2013 growing season in the coastal sorghum regions of Texas. (sorghumgrowers.com)
Sugarcane aphids will only survive and multiply significantly in sorghum genotypes, including Johnsongrass, shattercane, sorghum-sudangrass, sudangrass, forage sorghum and grain sorghum. (sorghumgrowers.com)
However, sugarcane aphids are distributed by the wind, so small colonies can be found in these crops, but at this time, they have not been found to be of economic importance. (sorghumgrowers.com)
The sugarcane aphid that infests sorghum is a different biotype than the sugarcane aphid that is found in sugarcane but they look identical in appearance. (sorghumgrowers.com)
Seed companies have now had multiple growing seasons to observe their hybrids and should have a good grasp of their tolerance level to sugarcane aphids. (sorghumgrowers.com)
Growers in those regions where sugarcane aphid has been a reoccurring issue should visit with their seed company representative as well as seek advice from regional extension agronomists and entomologists when choosing hybrids. (sorghumgrowers.com)
When choosing a sugarcane aphid tolerant hybrid, all of the criteria used for selecting a non-tolerant hybrid should be considered. (sorghumgrowers.com)
Sugarcane aphid can be controlled with good scouting and timely insecticide application, if needed. (sorghumgrowers.com)
Current commercially available tolerant hybrids are not immune from sugarcane aphid. (sorghumgrowers.com)
However, research has consistently shown that sugarcane aphids reproduce slower on tolerant hybrids and in some cases are able to withstand a higher sugarcane aphid population without a reduction in yield compared to susceptible hybrids. (sorghumgrowers.com)
They have identified better sources of sugarcane aphid resistance and tolerance and these qualities are now incorporated into many commercially available hybrids. (sorghumgrowers.com)
Check with your seed company on which of their grain sorghum hybrids are most tolerant to sugarcane aphid. (sorghumgrowers.com)
Unlike grain sorghum, there are only a few forage sorghum hybrids that have sugarcane aphid tolerance. (sorghumgrowers.com)
On a positive note, companies have been working to incorporate sugarcane aphid tolerance into their forage sorghum, particularly those used for silage. (sorghumgrowers.com)

MISSISSIPPI STATE -- Sightings of sugarcane aphids on sorghum crops, commonly known as milo, have increased rapidly from one Mississippi county in 2013 to the entire northern and central portions of the state this year. (msucares.com)
Last year was the first time producers reported seeing aphids feeding on sorghum and not just sugarcane, Catchot said. (msucares.com)
The sugarcane aphid, or Melanaphis sacchari, feeds on the vascular tissue that moves sugars through a sorghum plant. (msucares.com)
Entomologist and consultant Jared Pepper was scouting sorghum producer Matt Edgar's 100-acre crop in Yazoo County early this summer when he saw sugarcane aphids in that area for the first time. (msucares.com)
Resistance4
Emergence of Hessian fly biotypes that overcome resistance in most wheat varieties has led to supply shortages of wheat varieties resistant to Hessian fly. (uky.edu)
There were 187 genes that were highly expressed during the early time of aphid infestation in the SCA-resistant line, including genes encoding leucine-rich repeat (LRR) proteins, ethylene response factors, cell wall-related, pathogenesis-related proteins, and disease resistance-responsive dirigent-like proteins. (biomedcentral.com)
Host plant resistance has proven to be highly economical and eco-friendly long term insect management strategy [ 8 ] that has been broadly used for the management of other sorghum pests such as greenbugs ( Schizaphis graminum ) and corn leaf aphids ( Rhopalosiphum maidis ) [ 9 , 10 ].

Corn1

Polyphagous1
Polyphagous aphids often consist of host-specialized biotypes that perform poorly in non-native hosts. (bvsalud.org)
Resistant2
Aphid feeding on the SCA-resistant line upregulated the expression of 3827 and 2076 genes at early and late time points, respectively, which was relatively higher compared to RTx430 and SC1345 plants. (biomedcentral.com)
The problem with having only one product on the market is aphids become resistant really quickly," Catchot said. (msucares.com)
Crops1
For convenience that strain was referred to as strain B (biotype B), to distinguish it from the milder infestation of the earlier known strain A. Less than a year after its identification, strain B was found to have moved to tomatoes, and other fruit and vegetable crops. (wikipedia.org)
Pests1
Frisbie & Smith (1989) coined the termbiologically intensive IPM, which involves reliance on ecological methods of control basedon knowledge of a pests biology. (vdocuments.net)
Insects2
If you kill the beneficial insects, then the aphids will get out of hand really quickly," he said. (msucares.com)
The combinatorial analysis has great potential to identify biotype-specific effector candidates in aphids and other sap-sucking insects. (bvsalud.org)
Genes2
Co-expression network analysis revealed that aphid infestation modulates sorghum defenses by regulating genes corresponding to phenylpropanoid metabolic pathways, secondary metabolic process, oxidoreductase activity, phytohormones, sugar metabolism and cell wall-related genes. (biomedcentral.com)
The homologous genes of published aphid effectors were not differentially expressed between CU and MA. (bvsalud.org)

Malvaceae1
Here, we tried three strategies to identify possible effectors in Malvaceae- (MA) and Cucurbitaceae-specialized (CU) biotypes of the cotton-melon aphid Aphis gossypii Glover. (bvsalud.org)
Yield1
In the Delta, the yield was 20 percent less than what we had in the hills because we caught aphids late and never got 100 percent control of them. (msucares.com)
Grain1
They evolved a biotype or mutation that allowed it to feed on grain sorghum. (msucares.com)
Plants2
We used RNA-sequencing approach to identify the global transcriptomic responses to aphid infestation on RTx430, SC265, and SC1345 plants at early time points 6, 24, and 48 h post infestation (hpi) and after extended period of SCA feeding for 7 days. (biomedcentral.com)
Aphids also secrete sugary substance known as honeydew, which allows the growth of sooty mold and results in reduced leaf area for light absorption and photosynthesis in plants, thus declining the photosynthetic efficiency of infested plants. (biomedcentral.com)
Days1
That option costs the producer more on the front end, but it protects the crop from the aphids for 35 to 40 days after planting, Catchot said. (msucares.com)
Leaves1
When aphids are present and leaves are dry, you can see this shiny substance. (msucares.com)
Made1
Researchers think the aphid made a host shift, which is not uncommon with aphids," he said. (msucares.com)

Finally, we searched for DEGs of the 177 salivary proteins in the aphid-head transcriptomes, and the salivary proteins with expression differences were regarded as effector candidates. (bvsalud.org)
