Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola

Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola was established on 20th October, 1969 with its head-quarter at Akola. 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.

    KAIROMONAL EFFECT OF SOME PLANT EXTRACTS AND MOTH SCALES FOR IMPROVING THE PERFORMANCE OF TRICHOGRAMMA CHILONIS (ISHII)
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-06-28) KUMAR, DEVENDRA; Satpute, Dr. N.S.
    The study entitled “Kairomonal effect of some plant extracts and moth scales for improving the performance of Trichogramma chilonis (Ishii)” was undertaken at Biocontrol laboratory, Department of Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2018-19. The experiment was laid out in Completely Randomized Design (CRD) with six treatments and five replications. Studies were undertaken to evaluate the hexane extracts of male and female moth scales of host insects and hexane extract of various host plants for improving the performance of Trichogramma chilonis (Ishii) under laboratory and potted plants conditions. Male and female extracts of E. vittella and Corcyra was taken and leaves extracts of four plants namely cotton, brinjal, tomato and okra were taken along with a standard octacosane for studying their effect in improving parasitization by T. chilonis. The results revealed that treating irradiated eggs of Corcyra chephalonica with hexane extract of moth scales of female E.vittelia and female C.cephalonica at 10000 ppm has recorded maximum parasitism of 81.99% and 75.99% by T. chilonis, respectively whereas in control (Hexane), 40.66% parasitism was recorded. Maximum emergence of 71.03% was observed with C. cephalonica female moth scale extract followed by Earias female extract (70.08%). Similarly, the other biological parameters like fecundity and female longevity were also found to be influenced significantly by the moth scale extracts. Among the host plants tested, the hexane extract of cotton leaves has recorded 80.66% parasitism followed by hexane extract of tomato leaves (74.66%). Also maximum adult emergence (75.92%) was observed on hexane extract of tomato leaves followed by cotton leaves (72.67%). Maximum fecundity was obtained when egg cards were treated with hexane extract of cotton leaves with 70.4 eggs/female compared to control (Hexane) recording 42.2 eggs/female. Highest female longevity (9.2 days) and male-female ratio (1:0.96) were also recorded on hexane extract of cotton leaves. The present study also indicated that kairomonal compounds from hexane extract of host plants and host insects plays important role in increasing parasitization by T. chilonis on both cotton and pigeonpea plants under greenhouse conditions.
