How Whiteflies are Damaging Crops in India?
What is the News?
According to a study by ICAR- National Bureau of Agricultural Insect Resources, Invasive Whiteflies Species are increasing in India.
Whiteflies:
- Whiteflies are sap-sucking insects. They are members of the insect family Aleyrodidae (order Homoptera). These insects become abundant during warm climates and are found on houseplants and in greenhouses.
- Origin: Most of the whitefly species are native to the Caribbean islands or Central America.
- India: Around eight types of whitefly species are found in India. The first invasive whitefly was reported from Kerala in 1995. These species are now distributed throughout India except Jammu & Kashmir.
- Invasive Species: Whitefly species reduce the yield and also damage crops. Hence, they are considered as invasive species. These insects excrete sticky honeydew and cause the yellowing or death of leaves.
Key Findings of the study:
- Expanding host range: Whitefly species are expanding their host range (Species on which they feed) on valuable plant species like coconut, banana, mango, sapota, guava, cashew, oil palm, and important medicinal plants.
- Reason for expanding host range: The host range of all the whiteflies is increasing due to their polyphagous nature (ability to feed on various kinds of food) and prolific breeding.
- Resistance to available insecticides: Whiteflies have also been difficult to control by using available synthetic insecticides.
Suggestions:
- Monitoring of Whitefly Species: The administration should ensure continuous monitoring of the whitefly species, their host plants, and geographical expansion.
- Phytosanitary Measures: States should ensure stricter phytosanitary measures at relevant places to reduce the chances of incoming exotic species.
- Awareness among citizens: The state should work towards increasing awareness among the public about the threat posed by invasive species. This will help reduce the chances of the public indulging in illegal or unintentional import of invasive species.
- Biological Control Methods: As the whiteflies are getting difficult to control by using synthetic insecticides. Therefore, naturally occurring insect predators, parasitoids and entomopathogenic fungi (fungi that can kill insects) could be used as novel biological control of the invasive whiteflies.

“Dipcovan Kit” -DRDO develops Antibody Detection Kit —
What is the News?
Defense Research and Development Organisation(DRDO) has developed a Covid-19 antibody detection kit named Dipcovan.
About Dipcovan Kit:
- Dipcovan kit is a Covid-19 antibody detection kit. Defence Institute of Physiology and Allied Sciences lab of DRDO developed it in association with Delhi’s Vanguard Diagnostics Pvt Ltd.
- Purpose: Its primary purpose is to detect antibodies. It will also be used in Covid-19 epidemiology studies such as serosurveys.
- Antibodies are protective proteins produced by the immune system to attack antigens. The antigen is a toxin or other foreign substance that induces an immune response in the body.
- How does it work? DIPCOVAN is a DIPAS-VDx Covid-19 IgG antibody microwell ELISA. The kit can detect both spikes and nucleocapsid (S&N) proteins of the SARS-CoV-2 virus with a high sensitivity of 97% and specificity of 99%.
- The detection kit has been approved by Indian Council of Medical Research(ICMR).
- Significance: The kit offers a significantly faster turn-around time. It requires just 75 minutes to conduct the test without any cross-reactivity with other diseases. It also has a shelf life of 18 months.
About ELISA:
- Enzyme-Linked Immunosorbent Assay(ELISA) is a test that detects and measures antibodies in blood.
- The test can be used to determine antibodies related to certain infectious conditions.
- Some examples include HIV which causes AIDS, Rotavirus, Zika virus, Lyme disease among others.

UK’s Electronic Travel Authorisation Scheme
What is the News?
The United Kingdom(UK) has announced plans for a fully digital border with the launch of Electronic Travel Authorisation Scheme.
About Electronic Travel Authorisation(ETA) Scheme:
- The scheme is similar to the U.S.-style electronic travel authorization. It will pre-check the travellers coming to the U.K.
- Under this, visitors without a visa or immigration status have to apply for an electronic permit before coming to the UK.
- Among those who would need the Electronic Travel Authorisation (ETA) would be people arriving for short holidays or changing flights in the UK.
- However, people who wish to stay in the country for a long period of time – for example over six months – would need to obtain a visa rather than an ETA.
Significance of this new scheme:
- The system would allow automated and early security checks. It will stop foreign criminals from arriving in the country, with applicants only allowed to travel once they have been cleared.
- The scheme will also make it easier for the officials to count the numbers coming into the country.

SC Ruling on Personal Guarantor’s Liability for Corporate Debt
What is the News?
The Supreme Court has upheld the government’s move to allow lenders to initiate insolvency proceedings against personal guarantors.
Who is a personal guarantor?
- To showcase their intent to repay the bank loan on time, the promoters of some big business houses submit a personal guarantee to the lenders. It secures them loans easily and timely.
- It is sort of like an assurance from the owner or the owners of the company that the money borrowed by their company for various purposes shall be repaid on time as per the agreed schedule.
- Furthermore, it is different from the collateral. Indian corporate laws say that individuals such as promoters are different from businesses and the two are very separate entities. Thus, a promoter can give a guarantee for the company it is running
What is the issue?
- In 2019, the Government issued a notification. It allowed creditors, usually financial institutions and banks, to make a move against personal guarantors under the Indian Bankruptcy and Insolvency Code(IBC).
- The intention was to hold the guarantor promoters liable for the defaulting companies against loans.
- However, the notification was challenged by the promoters, claiming that it was always a management board that ran the company. Therefore, the promoters alone should not be held liable for the default on debt repayment.
What has the Supreme Court said?
- The Supreme Court has upheld the notification issued by the Government.
- The court said that there is a close connection between personal guarantors and their corporate debtors. Hence, it was this connection that made the government recognise personal guarantors as a separate category under the IBC.
Significance of this judgment:
- This judgment assumes significance as it will now allow lenders to go after personal guarantors even while bankruptcy proceedings against the ailing companies are pending. This will speed up the process for the recovery of dues.
