The pink bollworm menace

The pink bollworm is an insect known for being a pest in cotton farming.

The pink bollworm is native to Asia but has become an invasive species in most of the world’s cotton-growing regions.

Pink bollworm larvae specifically target cotton and are difficult to control because this damaging stage is found inside the boll. The female moth lays eggs in a cotton boll, and when the larvae emerge from the eggs, they inflict damage through feeding. They chew through the cotton lint to feed on the seeds.

The National Cotton Council of the USA estimates that the pink bollworm costs American cotton producers more than US$32 million each year in control and yield losses.

Pink bollworm threatenscotton crop in M’wada

Prasad Joshi  | TNN | Jul 28, 2020

Aurangabad: Pink bollworm has been found to have infested cotton crops in some parts of Marathwada, prompting the authorities concerned to ask farmers to use pheromone traps and pesticides.

The danger to the ‘cash crop’ from the pest ahead of likely bumper kharif season due to the good monsoon has left the farming community worried in Marathwada, which is known as the cotton cultivation belt.
Vasantrao Naik Marathwada Agricultural University, Parbhani, has alerted the farmers against the attack of pink bollworm on the cotton crop.

‘Pink bollworm is out of control in India’

KV Kurmanath, Hyderabad | March 13, 2019 

That pink bollworm has developed resistance to Cry1Ac and Cry2Ab (or Bollgard-II) — the two biotech solutions currently available in India to tackle pink bollworm — is no news.

Virulent attack of the pest is destroying the fibre crop on lakhs of acres across the country, particularly in the West, Central and Southern parts.

An American pink bollworm expert says that it is impossible to tackle the menace with the current two Bt toxins being used in the country. “It has gone out of control. It’s too late. Too little,” he points out when asked about the likely control mechanisms.

“The two genes that are being used in India are now ineffective. The resistance is widespread. There is no way we can set the clock back if we use these two Bt toxins,” Bruce Tabashnik, Head of Department of Entomology at the University of Arizona, who studies pest resistance and has done extensive study on pink bollworm and its resistance to Bt toxins, told BusinessLine.

Along with the deficient rainfall, the pest has triggered concern among farmers, even as futures and spot prices of ginned cotton continue to rule firm. 

Pink bollworm resistance towards the insecticides is a major issue of concern. Preventative treatment that might be applied during the pre-bloom period is discouraged because this can destroy many beneficial forms that keep bollworms and other pests under control. What can be done to get rid of the bollworms?

TermirepelTM a C Tech Corporation product is best to deal with the nuisance caused by this pink bollworm.

Termirepel™ is thermally stable and does not degrade on exposure to heat and sunlight. It does not kill or harm the insect but repels them. It does not volatilize and does not degrade the soil. It is RoHS, RoHS2, RoHS3, REACH, ISO, APVMA, NEA, EU BPR compliant and FIFRA exempted.

Our product 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, i.e. 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.

Our TermirepelTM masterbatch can be incorporated in the agricultural films, polymer materials, greenhouse films, polymer sprinklers, irrigation pipes, plastic parts from pumps and tractors used in the fields.

The product in the form of liquid concentrate can be mixed in paints and be painted on the concrete walls around the farms.

Our lacquer product can be applied to already installed applications. The lacquer is compatible with most of the surfaces like metals, wood, polymers, concrete, etc. It can be applied on the wooden fences around the farms and already installed pipes.

TermirepelTM does not kill the target species but only repels them thus balancing the ecology and thus helping in maintaining the goal of sustainability.

This product works on the mechanism of green technology. The product does not have any adverse effect on humans. Therefore, significant in today’s time and date as ecology salvation has become the prime focus.
