The planted crops are easily attacked by aphids causing a huge loss to the crop growers.
The evidence for the same is reported as below:
Kansas extension agent on sugarcane aphids: ‘A serious threat to industry’

Sedgwick County, Kan. (KSNW) – The Sedgwick County Extension Office has confirmed its first case of sugarcane aphids of 2017.
“It hasn’t been here long yet, so for the sorghum producers and farmers in the county, it’s definitely important that we now start scouting for this pest,” said Sedgwick County Extension Agricultural and Natural Resources Agent Zach Simon.
Simon said sugarcane aphids, true bugs that suck sap from plants, were found in a sorghum field near Colwich on Wednesday.
“These aphids have not been here for more than 10 days probably, at the longest,” Simon said.
However, Simon said it won’t take long for the aphids to spread and potentially cause damage to Kansas sorghum.
Agriculture University cautions farmers against Aphid damage to wheat crops

University (PAU) has advised the farmers to remain vigilant and regularly monitor their wheat crop for aphid damage.
“Aphids are the most important insect pests of wheat and their damage is observed in March. These are small, soft bodied, green to blackish green louse like insects found in colonies on leaves and earheads. Aphids suck sap from the leaves and maturing grains, “he said.
Due to heavy feeding by aphids, the grains fail to develop or remain shriveled, he told.
Aphids also excrete honeydew on which black sooty mould develops that affects the yield, he added. The high population of aphids at the earhead stage can cause substantial losses in yield, he warned.
They have proven to be the enemies of the growers, haven’t they?!
So, what is an aphid??
Aphids have soft pear-shaped bodies with long legs and antennae and may be green, yellow, brown, red, or black depending on the species and the plants they feed on. A few species appear waxy or woolly due to the secretion of a waxy white or gray substance over their body surface.
Generally, adult aphids are wingless, but most species also occur in winged forms, especially when populations are high or during spring and fall. The ability to produce winged individuals provides the pest with a way to disperse to other plants when the quality of the food source deteriorates.
There are numerous species of aphids found throughout the world. These garden pests are usually most active in the springtime and decrease with a rise in outside temperatures.
They live on plants, especially on the new plant growth and buds, and the eggs can survive the winter. Although aphids live in colonies, they will move to other plants when their host plant is dying or overpopulated.
Aphids are among the most feared pests among growers in temperate regions.
What kind of damage can they do?
Aphids passively feed on the sap of phloem vessels in plants and extract the plant’s fluids and nutrients which turn the leaves yellow and stunt shoots. Some species inject the toxin into plants, which causes leaves to curl and further distorts growth. The newly developed plant becomes unhealthy and hence may die but the larger plants may survive with some damage.
Aphids produce a sweet and sticky excretion known as honeydew which turns black when affected by sooty mold fungus. The black spots affect the photosynthesis cycle and the plant eventually die. The aphid’s honeydew not only attracts the sooty mold fungus but also ants because the honeydew contains necessary ingredients like amino acids, protein, and sugar the fungus and ant requires.
All these were the direct and indirect damages to the plant/crops but the most harmful consequence of aphids is the Transmission of Diseases. Aphids can transmit dozens of viruses from a diseased plant to healthy in few seconds, especially through the winged generation. The biggest problem with viruses is that there is no remedy for them so that the infection of a plant that is not tolerant or resistant to the virus leads inevitably to a decline in the final production.
There are many conventional methods to prevent the plants and crops from aphids but all are ineffective. Pesticides are used which have failed to keep these pests away from the crops.
Knowing all the damages caused by aphids and the ineffectiveness of the conventional methods use, let’s now know how to combat these pests.
C Tech Corporation can offer you the effective solution to overcome the damages caused by aphids, TermirepelTM is an ideal solution for prevention from inflicts of Aphids.
TermirepelTM works on the mechanism of repellency. It temporarily inhibits the mating cycle of the insects. The product impairs the ability of the insects to reproduce, that is the insects will not lay eggs or the laid eggs will be infertile. The product causes feeding disruption in an insect by triggering an unpleasant reaction within the insect which might try to feed on the application. The product temporarily blocks the reproduction system of the insects by hindering the release of the vital hormones for growth.
TermirepelTM is a non-toxic, non-hazardous, non-carcinogenic and anti-insect aversive. It is RoHS, RoHS2, ISO, REACH, APVMA, NEA compliant and FIFRA exempted.
TermirepelTM is developed on the basis of green chemistry and technology.
TermirepelTM is available in the form of a masterbatch, liquid concentrate, and lacquer.
TermirepelTM masterbatch can be incorporated in plastic tree guards, fencing of trees, mulches, films, guard bags etc.
