Locust attacks in Rajasthan have turned severe after three decades and hence there is a need to strengthen the Locust Warning Organisation, Chief Minister Ashok Gehlot said on Friday. Addressing Agriculture Department officials, District Collectors and Locust Warning Organisation officials, over video conference, he said: "This time, the locust attack has been quite different as these locusts have moved from the border areas to Ajmer, Jaipur, Karauli, Tonk, Dausa, Sawai Madhopur and other districts." "We have to work new ways to control them," he said, adding that the Prime Minister's attention was also drawn towards the issue during the video conference held with him recently. Since the Locust Warning Organisation comes under the Centre, the Central government should strengthen it and provide necessary resources, he added. (IANS)
