This Agricultural University was named after the illustrious son of Vidarbha Dr. Panjabrao (alias Bhausaheb) Deshmukh, who was the Minister for Agriculture,Govt. of India. The jurisdiction of this university is spread over the eleven districts of Vidarbha. According to the University Act 1983 (of the Government of Maharashtra), the University is entrusted with the responsibility of agricultural education, research and extension education alongwith breeder and foundation seed programme. The University has its main campus at Akola. The instructional programmes at main campus are spread over in 5 Colleges namely, College of Agriculture, College of Agricultural Engineering & Technology, College of Forestry, College of Horticulture and Post Graduate Institute. At this campus 4 degree programmes namely B.Sc.(Agri.) B.Sc. (Hort.), B.Sc. (Forestry) and B.Tech. (Ag. Engg.) , two Master’s Degree Programmes viz. M.Sc.(Agri.) and M.Tech. (Agri.Engg.) and Doctoral Degree Programmes in the faculties of Agriculture and Agril. Engineering are offered. The University has its sub-campus at Nagpur with constituent College, College of Agriculture which offers B.Sc.(Agri.) and M.Sc.(Agri.) degree programmes. The Nagpur Campus is accomplished with a garden, surrounded by its natural beauty and a well established Zoo which attract the general public and visitors to the city. A separate botanic Garden is being maintained on 22 hectares with a green house for the benefit of research workers. In addition there are 2 affiliated grant-in-aid colleges and 14 private non-grant-in-aid colleges under the umbrella of this University A Central Research Station is situated at the main Campus which caters to the need of research projects undertaken by Crop Scientists of the principle crops of the region are Cotton, Sorghum, Oilseeds and Pulses.

    IN VITRO ASSESSMENT OF SOME IPM COMPONENTS AGAINST MAJOR SUCKING PESTS OF COTTON
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-06-14) ARYA, KRISHNA; Kolhe A. V.
    The present investigation entitled “In vitro assessment of some IPM components against major sucking pests of cotton” was carried out during the year 2017-2018 in Department of Agricultural Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The data on mean prey consumption on all prey densities at different time periods of 3, 6, 9, 12 having equal time intervals showed that the predator feeds maximally during the first 3 hours of exposure to the prey and the amount of aphids fed decreased for the next 3 hour interval. The proportion of prey consumed also keeps on decreasing as the prey density increases for the first time period of 3 hrs and also for cumulative time periods of 6, 9, 12 and 24 hrs after exposure of the predator to the prey. The attack rate ‘a’ at a cumulative exposure of first 12 hrs was found to be higher, 0.0391/12 hrs as against to a lower attack rate at cumulative exposure of next 12 hrs i.e., 0.0254/24 hrs. However the handling time ‘Th’ was found 0.3654 hrs (21.92 min) after 12 hours of cumulative exposure which increased to 0.4441 hrs (26.65 min) after next 12 hours of cumulative exposure. This shows that the predator was more efficient as a biocontrol agent during the first 12 hrs of exposure to the prey than after that time period. In the field population of A. biguttula biguttula collected from the village of Chandur, district Akola, the LC50 of imidacloprid and acephate was worked out as 95.92 ppm and 483.37 ppm respectively. Similarly from Kanshivni village, district Akola the LC50 of imidacloprid and acephate was worked out to be 175.51 ppm and 607.76. However, in the field susceptible population of leafhopper LC50 value of imidacloprid and acephate was 21.68 ppm and 51.11 ppm respectively. Relative Toxicity of imidacloprid was higher as compared to acephate at all locations. Imidacloprid was 5.04, 3.46 and 2.36 times more toxic than acephate at Chandur, Kanshivni and in field susceptible population. Resistance to acephate and imidacloprid was observed at both the locations with resistance fold being greater for acephate. Relative Resistance to imidacloprid was 4.42 fold and 8.10 fold at Chandur and Kanshivni respectively. The Relative Resistance to acephate was 9.46 fold and 11.89 respectively.
