Question

Consider the following statements related to the locust infestation:

1. They originate in Rajasthan as Deserts provide the perfect bare ground for laying eggs.

2. The rainfall in these regions will produce enough green vegetation to enable both egg-laying and hopper development.

3. In India Ministry of Earth Sciences is responsible for monitoring, survey, and control of Desert Locust.


Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3​

Answer 1

Option A - 3 Only.

☆ More Information :-

• Indian Agriculture is highly prone to Desert Locust. The Desert Locust is a trans-boundary pest that can cause irreparable damages.

• Locust Control and Research is a sub-component under the Sub Mission on Plant Protection and Plant Quarantine (SMPPQ), a scheme under Green Revolution (Krishonnati Yojana) through which regulatory, monitoring, surveillance, and capacity building functions are performed.

• In order to keep the menace of locust at bay Locust Warning Organization (LWO) has been established.

• Locust Warning Organisation (LWO), Directorate of Plant Protection Quarantine and Storage, Ministry of Agriculture & Farmers Welfare, Department of Agriculture, Cooperation & Farmers Welfare is responsible for monitoring, survey and control of Desert Locust in Scheduled Desert Areas mainly in the States of Rajasthan and Gujarat. Hence statement 3 is not correct.

• Locusts normally live and breed in semi-arid/desert regions. For laying eggs, they require bare ground, which is rarely found in areas with dense vegetation. So, they are more likely to breed in Rajasthan than in the Indo-Gangetic plains or the Godavari and Cauvery delta. Hence statement 1 is correct.

• While green vegetation is good for hopper development – the stage between the nymph that has hatched and before its turning into a winged adult moth – such cover isn’t widespread enough in deserts to allow the growth of large locust populations. Hence statement 2 is correct.
